A senior technical leader, one day a week
For seed and Series A teams that need real architecture ownership, hiring judgment, and a board-ready technical story, without the cost or commitment of a full-time CTO.
Ways to work together
Advisory
2–4 h / weekA sounding board for your founding engineers, architecture calls, tradeoffs, and hiring input on demand.
Fractional CTO
1 day / weekI own the technical direction, architecture, roadmap, hiring, and the board narrative, as part of your leadership team.
Tech Due Diligence
Fixed scopeIndependent assessment of a target's architecture, team, and risk, for investors and acquirers who need the real picture.
Equity partner
SelectiveFor an early product I truly believe in, I can take part of my compensation in equity and carry the technical side the way a co-founder would.
What I take off your plate
Architecture decisions
The load-bearing choices, made and documented.
Hiring & interviews
Scorecards, panels, and closing senior talent.
Roadmap sanity
What to build now, and what to defer.
Code quality gates
Review standards that scale with the team.
Cloud costs
Spend that tracks value, not surprises.
Board-ready tech narrative
The story your investors need to hear.
Most teams do not need a full-time CTO, they need senior judgment applied at the right moments by someone with enough context to be accountable for it, and that is a one-day-a-week job when the process is honest.Evgeny Bereza · birch
