Fractional CTO for founder-led AI companies

Your prototype shipped in a weekend. Your product shouldn't take a month.

I work inside your codebase, your delivery system, and your engineering team to find where production work slows down — and materially improve shipping velocity over 90 days.

The velocity gap

The gap is real — and it has a fixable cause.

You ship a working prototype over a weekend. Your engineers take two weeks to ship something smaller. The math doesn't add up, and no one in the room can explain why.

The cause is the distance between a demo and production: the tests, reviews, and infrastructure that make software safe to ship. That distance is hard to see from the outside, and it rarely gets translated into language a founder and an engineer can share — so it shows up as friction instead of a conversation.

Case study

A seed-stage team that could not ship what it demoed.

Situation

A founder-led team building agentic finance software. The founder was producing working prototypes in days; the engineering team needed weeks to get comparable work into production. Neither side could explain the difference, so it was being read as a performance problem.

What I found

The gap was not effort or talent. Production work was queuing behind manual review, a test suite nobody trusted enough to release on, and environment differences that turned every release into a negotiation. AI-assisted code was entering the repository faster than the review process could absorb it.

What changed

We started managing review capacity rather than coding speed: clear ownership per area of the system, smaller change sets, a test suite the team was willing to stake a release on, and an explicit operating model for where AI-assisted work is and is not allowed to go straight to review.

Where it landed

Releasing stopped being an event that needed coordinating and became something the team does on its own. The founder stopped being the escalation path for engineering decisions, and the conversation moved from why is this slow to what should we build next.

“His vibe coding seems to move faster than SDEs delivering features.”— Founder, seed-stage agentic-finance company
What I do

I find where engineering velocity is being lost — and work inside the team to recover it.

Start from the code

I form my read from your repo, your pull requests, and your pipeline — the real artifacts. Depending on your product and team, I pair that with focused conversations to fill in what the code alone can't show.

Close the velocity gap

I find where work actually stalls and rewire it so features ship at the speed your prototypes promise.

Bridge founder and team

I turn what you want into what your engineers can build, and their concerns into decisions you can make, working embedded with your team.

Set engineering strategy

I set engineering strategy with you: what to build now, what to defer, where to invest, and how the architecture, roadmap, and team evolve as you scale.

How it works

Ninety days, three stages.

01

Fit call

Thirty minutes, free. We work out whether a velocity gap is really your constraint. You leave with a written scoping memo and a recommended next step, whether or not we work together.

02

Engineering diagnostic

Weeks 1–2. I read your engineering end to end — team, architecture, delivery, AI workflows — and hand you a state-of-engineering report, baseline delivery metrics, risks ranked by business impact, and a prioritized 90-day plan.

03

Embedded implementation

Weeks 3–12. I work inside your team on shipping cadence, code review, architecture decisions, hiring, and the calls that have stalled. Founder-mode means I work directly in the artifacts and decisions — not as an adviser who appears for one weekly meeting.

Fit

Who this works for — and who it doesn't.

A good fit

  • You have a working product or a credible prototype.
  • You prototype faster than your team can productionize.
  • You have roughly 4–30 engineers.
  • Release speed is a business constraint, not an annoyance.
  • You want hands-on leadership inside the team, not an agency.

Not a fit

  • You need an outsourced team to build an MVP.
  • You want occasional architecture advice, not embedded work.
  • You have no internal engineering team yet.
  • Your core problem is product–market fit, not execution.

Questions

What founders ask before we start.

Will you sign an NDA?

Yes. I sign your NDA before the fit call if you want the conversation covered from the start, and always before I am given access to anything — code, metrics, roadmap or people.

How is access to our repository handled?

On your terms and through your normal process. I use an account your team provisions, with the same permissions and offboarding as any engineer, and I do not copy source code onto machines outside the access path you approve.

Do you write production code?

Yes, where it is the fastest way to unblock the team or to prove a pattern is workable. I am not a contract developer, though — the goal is that your engineers keep shipping after I leave, so most of my time goes into review, architecture decisions and the delivery system rather than feature volume.

How much time do you spend with the team?

Enough to be a participant rather than a visitor. During the diagnostic I am in your artifacts daily; during the embedded stage we agree a rhythm that fits how your team already works, including reviews, planning and the decisions that have stalled.

Do you replace our engineering leader?

No. If you have one, my job is to make them more effective, not to sit above them. If you do not have one, I hold the role temporarily and help you hire the person who will keep it.

What if we already have a CTO or VP of Engineering?

That is a common and productive setup. They own the team and the roadmap; I bring an outside read on where delivery is losing time, and a second experienced pair of hands on the decisions that are hardest to make from inside.

Can you help us hire?

Yes. That usually means defining what the next two or three roles actually need to be, writing the scorecards, running technical interviews with you, and calibrating offers — not sourcing.

What happens after 90 days?

The embedded stage is designed to end. You keep the state-of-engineering report, the operating changes and the plan. Some founders continue at a lighter cadence, some bring me back for a specific decision later, and some are done — all three are fine outcomes.

Do you work with competing companies?

No. I take one engagement at a time in any given market, and I will tell you before we start if there is an adjacency you should know about.

What size and stage do you work with?

Founder-led software companies with roughly four to thirty engineers, a working product or a credible prototype, and release speed that has become a business constraint. The fit section above is the honest version of this answer.
