Fractional technology leadership Kansas City, MO

A CTO who still reads the code.

Thirty years of building software and the organizations that ship it. I take the technology leadership seat by the month — set the architecture, steady the team, and stay close enough to the work to know whether it is actually going well.

Why people call

Two situations bring most people here.

Neither one is a staffing problem. Both are judgment problems — and judgment is the thing that is hardest to hire quickly.

There is a team, and no one senior enough to steer it.

You have engineers — maybe your own, maybe an agency, maybe an offshore partner — and a roadmap that keeps sliding right. The effort is real. What is missing is someone who can tell sound technical judgment from confident-sounding technical judgment, and who has the standing to act on the difference.

There is a decision you cannot take back.

A cloud migration. An acquisition. A re-platform. A build-versus-buy call where being wrong stays expensive for years. You want someone who has done it before, who will say the unwelcome thing early, and who has no stake in which answer you pick.

How I think about it

The decisions that got you here are the ones holding you back.

Every technical decision has a stage it is correct for. The difficulty is that the stages contradict each other — what was right at the start is exactly what is slowing you down later, and founders reasonably read that as somebody having made a mistake. Usually nobody did. It is the frame I use inside engagements.

These are stages of a product, not a company. An established business launching something new has that product back at the start, and a portfolio can easily hold products at three different stages at once — which is usually where the arguments come from. Pick the stage that fits the product you have in mind.

THE SIX STAGES OF A DIGITAL PRODUCTCUSTOMERS · REVENUETIMEZero to oneEarly adopterValley of deathProduct-market fitScalingMaturity
Stage 01

Zero to one

Get one customer.

Going from nothing to a first customer or user. Speed, rapid prototyping, flexibility, and direct user engagement, all in service of validating the idea. Build the smallest amount of product that teaches you the most, then change based on what it taught you.

You are here if

0 of 5 match

Everything here is in service of learning fast. The most expensive mistake at this stage is building as though you already know the answer.

Stage 02

Early adopter

Gain multiple users, and validate.

With the first users onboard, the focus shifts to gaining more of them and leaning on early adopters for feedback and validation. Refine the product on user insight, begin scaling operations slightly, and lay the groundwork for broader market penetration. Speed to learning and change is still the thing that matters most.

You are here if

0 of 5 match

The trap here is mistaking enthusiastic early adopters for a market. They tolerate rough edges that later customers will not.

Stage 03

Valley of death

Which of the features and ideas you have built will actually scale the customer base?

The first two stages establish what is desirable, feasible, and viable. But getting your first few customers is often the easy part. This stage asks a harder question: of everything you have built, which of it scales? Most companies do not make it out of here. That is why it has the name it has.

It is also, by a wide margin, the stage I am called into most often.

You are here if

0 of 11 match

If several of those landed, that is the conversation I have most weeks.

Stage 04

Product-market fit

Optimize, and start scaling the infrastructure.

Reaching product-market fit means the product satisfies a strong market demand. The emphasis moves to optimizing the product, scaling infrastructure, and improving the experience on comprehensive feedback, in order to support growth and prepare for real scale. Process starts to matter considerably more than it did.

You are here if

0 of 8 match

This is where infrastructure decisions get expensive to defer. It is a good moment to have someone senior look at the foundations before growth makes them permanent.

Stage 05

Scaling

Process, and scaling the company itself.

With product-market fit established, the company focuses on rapid growth: expanding the user base and scaling operations. Technical scalability, team expansion, process optimization, and entering new markets are the critical activities. Process becomes essential to keep scaling without losing quality.

You are here if

0 of 7 match

Hiring outruns process at this stage, and the architecture usually outruns both. Most of my Build & Modernize work starts here.

Stage 06

Maturity

Innovation, expansion, and diversification.

The product is well established, with meaningful market share and stable growth. The work becomes innovation within the product lines, operational efficiency, market expansion, and diversification — holding position while finding new avenues for growth.

This is also where most established organizations and associations sit: twenty years of decisions, each defensible when it was made, collectively expensive to change.

You are here if

0 of 6 match

Modernization at this stage is rarely a rewrite. It is sequencing — deciding what to move, in what order, without stopping the business.

Services

Five ways to engage.

Most engagements begin as one of these and grow into another. Software development, integration, data, AI, product, and people leadership are not separate practices here — they are what one technology leader has to be fluent in at the same time.

S/01

Fractional CTO

Org designArchitectureHiringPartner oversightBoard comms

I take the technology leadership seat. That means the architecture calls and the roadmap, but equally it means hiring, standards, performance conversations, and translating all of it for a board or an investor without hand-waving. I run your team the way I ran my own — and I stay hands-on enough that nobody has to summarize the codebase for me.

When the team is external — an agency, an offshore partner, or no engineering organization at all yet — the work shifts to sourcing the right partners and holding them to account. Several of my engagements have looked exactly like that, and when every line of code is written outside the building, choosing who writes it is an architectural decision.

Typical: 2–4 days per month, ongoing

S/02

Data & AI Enablement

Data modelingAI strategyAgentic deliveryADRs & standardsAgent access

Most AI problems turn out to be data problems in a costume. I get the data modeled, migrated, and trustworthy first, then sequence the AI work that is genuinely worth doing and name the parts that are not yet. I also build with agentic tooling every day, which is why a one-person engagement can move at a pace that used to take a pod.

AI is a force multiplier for whatever discipline you already have, which means it multiplies the absence of it just as faithfully. The questions I get most are how to build fast with it without boxing yourself in, how to get uniform code out of several developers and several agents, and what to write down — architecture decision records, standards, the rules a team and its tooling both follow.

The newer one is access. When agents rather than other software are the callers of your APIs, the assumptions your authorization model was built on quietly stop holding.

Typical: scoped per engagement

S/03

Build & Modernize

Build vs. buyCloud migrationAWSIntegrationRe-platforming

Data center to cloud. Oracle to PostgreSQL. Scattered systems onto one platform with a single identity model. This is the unglamorous, high-consequence work of moving a running business onto better foundations without dropping it — and it lives or dies on sequencing, and on someone actually reading the code being moved.

I am also happy to talk you out of building something. Custom software is the most expensive kind to own, and the invoice arrives every year after the one you budgeted for. Buy it where something proven already fits, build only where the thing is genuinely yours, and spend the difference on the parts that actually differentiate you. I have no bench to keep busy, so that advice costs me nothing to give honestly.

Typical: 3–12 months, embedded with your team

S/04

Assessment & Technical Diligence

Maturity scoringM&A diligenceVendor review

A scored read on a digital product company — yours, a partner's, or one you are about to buy. The model works across three dimensions: strategy, where the product is headed and why; performance, how it is doing today and how well the organization converts and retains; and capabilities, how well the team actually executes and whether the technology suits the stage they are in.

Every finding is weighed against the stage the product is actually in, which is what keeps the result honest. Hold a company hunting its first customer to mature-company standards and you get conclusions that are unfair, wrong, and flattering in the worst way — because premature investment looks like maturity right up until it doesn't. I built the methodology on a live acquisition, and it produces a document you can act on and defend, not a deck.

For sponsors and acquirers, that means a defensible read on a target before the deal closes, and a costed view of the remediation you would be taking on.

Typical: 1–3 weeks, fixed fee

S/05

Leadership Coaching & Team Development

1:1 coachingCareer laddersDelivery discipline

One-on-one work with VPs, directors, and first-time managers, plus the team-level version: review culture, career ladders, and how decisions get made and written down. I have been the person who needed this and the person responsible for providing it, across a firm that grew to sixty-five people. Both experiences shape how I do it.

Typical: monthly retainer

Selected work

Four engagements, described honestly.

Including a migration whose first cutover failed, and a product that never reached market. Case studies where everything went well are not case studies, they are advertisements.

Netsmart

  • SectorPE-backed healthcare software
  • Client since2012 — across two of my companies
  • RoleData-layer risk analysis & phased migration structure
  • Scale~1,800 tables · ~8TB · 10 teams
  • ScopeData center to AWS; Oracle to Aurora PostgreSQL; SQL Server to Redshift

A database is not storage. It is where years of business logic and quiet optimization accumulate — and if you treat it as something to simply move, you will miss where most of the complexity actually lives.

Read the detail

Netsmart has worked with me since 2012, across two of my companies. That is the part I would point at first: this is not a project, it is a fourteen-year relationship, and the hard work only gets handed to people who have already earned it.

Most recently, leaving a private data center for AWS: roughly 1,800 tables and 8TB of data off Oracle and onto Aurora PostgreSQL, driven by Oracle licensing costs and the smallest downtime window we could manage. It became considerably broader than that in practice. The Java application had to be containerized onto ECS, Oracle-specific database logic had to be rewritten, reporting had to move off SQL Server onto Redshift, and networking and performance had to be reconsidered for a cloud environment entirely.

My focus early was finding the risk in the data layer and shaping a phased approach around it. Oracle-specific behavior sat deep inside stored procedures. Date and time handling had to be evaluated case by case, because no global rule existed. Primary keys that were perfectly fine in Oracle had to be rethought as BIGINT. Performance assumptions did not survive the move. None of that appears in an architecture diagram. It appears when you start moving things.

So we broke it into four phases to bound the risk: application to AWS on containers with Oracle still in place, Oracle to RDS to cut the data center dependency, Oracle to PostgreSQL, then reporting to Redshift.

The first full cutover did not go well. We had load tested and validated the key workflows, but real users surfaced performance problems tied to years of tuning and client-specific optimization that were never in our test scenarios. We rolled back — which was possible only because the phasing had been built to allow it. The whole thing was harder and more expensive than anyone planned for. The platform is now fully on AWS and PostgreSQL, positioned to actually use cloud-native architecture rather than reproduce what was there before.

ABOUT Healthcare

  • SectorHealthcare software
  • RoleTechnical & product diligence lead
  • ContextPre-acquisition evaluation
  • ModelStrategy, performance, capabilities — scored against developmental stage
  • OutputMaturity methodology & scoring model

Praise an early-stage company for meeting mature-company standards and you conceal the fact that it invested prematurely in things it does not yet understand. That is a bad thing wearing the costume of a good one.

Read the detail

ABOUT was evaluating a company it intended to acquire and needed more than a surface read on the target's technology and product organization. So we built a multi-factored model that drills into a digital product company across three dimensions.

  • Strategy — Where is the product headed, and why? What does the company actually intend it to become?
  • Performance — How is it performing today? How do customers find it, how effectively does the organization convert opportunities, and what does retention look like?
  • Capabilities — How well does the organization execute the strategy? What is the team like, how do they build, and is the technology appropriate to the stage they are actually in?

That last clause is the part that makes the model work. Products move through common developmental stages, and one still hunting its first customer cannot be judged against a mature one without producing conclusions that are both unfair and wrong — and that obscure what is genuinely good about the business. Every finding is weighed against the stage the product is actually in. For a target with a portfolio that means several answers rather than one, and the gap between them is usually where the interesting findings are.

We gathered what we could through conversations, artifacts, and observation, then tracked each answer, judged whether it was developmentally appropriate, and classified the risk attached to it. The deal team came away with a defensible, comparable picture of what they would be buying — and, just as usefully, a costed view of what it would take to fix.

A wealth management software startup

  • ClientUnnamed — still in stealth
  • SectorWealth management software — a product company, not an advisory firm
  • RoleTrusted technical advisor
  • Context10-person offshore team, zero external customers
  • FindingMature-company engineering at a pre-customer company
  • OutcomeRedirected early; in internal use, still pre-launch

A ten-person offshore team, a hand-built identity system in Azure, and no customers outside the founders' own firm. Each of those is defensible alone. Together they describe a company solving a mature company's problems before it had solved its first.

Read the detail

The founders are not technical, but they know their business cold: they run a successful wealth management firm, and years of that had shown them exactly where the tooling falls short. The product idea was to sit on top of the many back-office applications a wealth management firm depends on to serve its clients. That is genuine founder insight, and it is why the company was worth advising in the first place.

The build had been contracted to an outsourced firm with a local account rep and an engineering team overseas. The first call I joined had ten people on it. The only user was the founders' own firm — real validation, but not the same test as a first customer with no stake in the company.

A month in, the money was going into hand-coding an identity model in Azure and standing up infrastructure sized to one firm's requirements. Meanwhile the thing the product actually needed — a way to integrate the assorted back-office systems a second customer would arrive with — did not exist. Much of the build was either mature-company work or so specific to one integration that landing customer two would cost about what customer one had. And ten people were burning cash against zero revenue.

So I pushed them to stop and rebuild for the stage the product was actually at — what gets you to the next phase of the lifecycle, not the one after that. They did, and it cost a fraction of what continuing would have.

The product has not gone to market. It is in use inside their own firm, which is real value, but the outside launch has not happened yet. I would rather say that than round it up: outside advice can redirect what a company spends and stop a bad trajectory early, and here it did. What it cannot do is decide when, or whether, a company goes to market — that call belongs to the founders, and weighing it against a firm that already works is a reasonable thing to take time over. The spend was significant. On the original trajectory it would have been far larger.

MCAA

  • SectorNational trade association
  • RoleFractional CTO — no in-house technology team
  • ScopeShared platform, identity, two application rewrites
  • Scale~165,000 labor units migrated and validated
  • DeliverySourced and managed external development partners
  • StackAWS, Cognito, PostgreSQL, Salesforce

MCAA has no internal engineering organization. Every system that serves their members is built by someone outside the building — which makes choosing and managing those partners a form of architecture.

Read the detail

Two custom applications needed modernizing: WebLEM, the labor-estimating platform, and NCPWB, which serves their certified pipe-welding bureau. Both had been built as independent silos. Meanwhile a growing list of third-party software vendors were integrating MCAA's labor data into their own products, with no coherent way to understand who was using what.

Part of my role is simply being the technology function they do not have: finding development partners who are genuinely good, then managing those relationships closely enough that the work actually lands. They also needed a real identity strategy — both to give members one coherent experience across applications, and to see how members and third parties were using their data. Rather than solve that twice, I made the call to stand up one shared platform environment that both the labor and welding applications sit on: a single identity model built on AWS Cognito, one set of common services, and Salesforce membership as the source of truth. Identity is not worth hand-rolling — the judgment was in the membership model and the integrations, not in reimplementing authentication that Cognito already does better than we would.

The WebLEM overhaul ran with an outside development agency that I oversaw, with me as architect and a hands-on contributor alongside them. The legacy application had business rules hardcoded throughout the codebase, so the real first task was modeling the domain properly — the part of this work I care most about getting right. Once the model was sound, the harder problem was moving decades of legacy data onto it: roughly 165,000 labor units, each one a number some contractor will eventually put on a bid. I leaned heavily on AI to build a comprehensive migration and validation system that checks the new engine against the legacy output across all of them, rather than trusting the migration on faith. In an estimating product, a difference in the fourth decimal place is a real dollar figure on a real job.

The NCPWB rewrite began a few months ago with a team I would put against anyone's, and it is already integrated with the shared platform services. Significant UA integrations are ahead, and they will create real value on all sides.

Also: a shorter technology assessment and strategy work for Buttonwood Financial Group. Under the Artisan flag, delivery work for US Engineering, WellSky, Opendorse, FanThreeSixty, SportsEngine, Cynergy Wellness, and Cerner.

Companies I have built

Four companies. Not all of them worked.

Anyone can publish the wins. What you actually want to know about the person you are handing your technology to is how they behaved when it went the other way — and whether they can tell the difference between a problem they controlled and one they did not.

Beyond the Scores

Founder & CEO · 2011–2016
Athlete-centered sports SaaS
Acquired — SportsEngine

Bootstrapped from nothing on AWS: one of the first athlete-centered SaaS platforms for youth and amateur sports. Everyone else was building league-centric software. We built for the real-time information needs of athletes and their parents instead — which made adoption viral, because parents went and pushed their own clubs onto the platform.

It grew to support 750+ competitions across 20 countries and became a leading provider of technology to gymnastics organizations. SportsEngine acquired it in 2016. I stayed on for the following year to lead the integration into their platform and run the Kansas City office, including architecting a new registration system on SportsEngine's payments infrastructure. This one worked.

Viagio Technologies

Founder & CEO · 2011–2023
Founded as Artisan Technology Group
Built to 65, then scaled back

A custom software development firm, started the same month as Beyond the Scores. I grew it from a startup to sixty-five people and $8.5M in revenue, acquired two other companies along the way, held top-quartile Net Promoter Scores, and took it to #180 on the Inc. 5000 in 2021.

Then the market swung hard against custom development, and I led the work of scaling it back — which meant parting with genuinely excellent people who had done nothing wrong. Downsizing a company full of talent like that is an extremely difficult thing to live through, and I do not intend to describe it as a learning experience.

My partner wanted to keep it going and had the capital to keep backing it. I left in November 2023 and started Blue Sprout on my own. Those were among the hardest decisions of my career, and they are a large part of why I take the leadership half of this work as seriously as the technical half.

Tuerri

Chief Technology Officer · 2022–2023
InsurTech for Guidewire InsuranceNow
Never gained traction

A turnkey mobile product for property and casualty carriers: a branded iOS and Android app fully integrated into their Guidewire InsuranceNow environment, covering claims, payments, policy and coverage details, and offline proof of insurance.

I was CTO from 2022 to 2023 and guided the technical direction and the Guidewire integration work. My day-to-day involvement was limited, though, and that was the problem rather than an excuse for it: Tuerri needed considerably more capital and a leader with the capacity to drive it daily. Viagio had most of my attention, and I could not give this what it actually required. The entity still exists; the company did not take.

It is on this list because a list with it left off would be a highlight reel, and a highlight reel is not useful to you.

Blue Sprout Consulting

Founder & Principal · 2024–present
Kansas City, MO
Current

Where the work goes now. Independent by design: there is no bench to keep busy and no incentive to recommend a larger engagement than the problem actually deserves.

I hold a small portfolio deliberately — a limited number of clients at any one time. The model only works if I can operate as an actual member of your leadership team rather than a vendor you have to manage.

Everything above is why the advice is worth what it costs. I have made the calls, carried the payroll, and been wrong in public.

About

Mike Zimmerman

Founder, Blue Sprout Consulting. Kansas City, Missouri.

I took a computer science degree out of Nebraska in 1995 and started at Cerner the following January, where I stayed a decade — finishing as a senior software architect leading a team of six responsible for the technical architecture behind Cerner Millennium: middleware, security, internationalization, and system management. That is where the healthcare depth comes from, and it is not a coincidence that four of my clients since have been healthcare software companies. After Cerner came Chief Software Architect at National Marketing Resources, then senior architect at Softek Solutions.

In 2011 I co-founded two companies at once and spent the following twelve years finding out what that costs. Beyond the Scores was acquired by SportsEngine in 2016. Viagio I built to sixty-five people and $8.5M in revenue, and to #180 on the Inc. 5000, before the market turned and I had to take it back down. Somewhere in there I have met payroll, lost the deal, and sat in the room where everyone finds out the estimate was wrong.

Blue Sprout has been my own practice since January 2024. Thirty years in and roughly two hundred projects along, what it adds up to is not a longer list of technologies. It is pattern recognition — knowing which of the ten things going wrong is the one that actually sinks the quarter — and a willingness to say the unwelcome thing early, while it is still cheap to act on. I learned the value of that the expensive way.

I work with founders between seed and Series B who need senior technology leadership well before they can justify hiring it, and with established organizations — growth-stage, PE-backed, and often regulated — carrying twenty years of systems that no longer match how they operate. Both need the same thing: someone who can hold the strategy and the code in their head at the same time.

Excellence is not a choice. It is the standard.

How I work
  • Great communicationYou should never wonder what is happening or what it means. Written down, in plain language, before you have to ask.
  • CuriosityBe curious, not judgmental. Yes, that is from Ted Lasso. It is still the fastest way to find out why a system is the way it is.
  • SelflessnessThe engagement succeeds when your team is stronger than when I arrived — including in the parts that never needed me.
  • QualitySpeed that creates rework is not speed. I would rather be right on the third day than confident on the first.
  • Have funHard technical work goes better when people are not miserable. That turns out to be a delivery strategy, not a perk.

Every role, every date, the full record — that lives on LinkedIn, and it is kept current.

Full background on LinkedIn
In the Kansas City community

Kansas City has a genuinely good startup ecosystem, and most of what I know about early-stage companies I learned inside it.

  • Digital Sandbox KC

    Review panel

    I sit on the panel that evaluates companies applying to the program — going deep on the business model and the technical approach, then deciding as a committee whether a company is a fit for Digital Sandbox and its grant-backed funding. It is the same work as the technical diligence I do commercially, done for the ecosystem rather than for a fee.

  • Pure Pitch Rally

    Technical workshop lead

    I lead the technical workshop that every Rally company attends, walking founders through the maturity lifecycle above and the decisions that belong to each stage. It is the part of the job first-time founders find hardest, and the part nobody warns them about.

  • Helzberg Entrepreneurial Mentoring Program

    Mentee, then Fellow

    I came up through HEMP as a mentee and served as a Fellow for several years afterward. Much of what I understand about running a company — including the parts that went badly — I worked out with other HEMP entrepreneurs in the room.

  • KC Tech Council

    Former board member

    Board service with Kansas City's technology industry association, working on the health of the regional tech sector and the pipeline of people entering it.
