Fractional CTO
CTO-level leadership.
Without the C-suite salary.
You don't need a $250K/year CTO to make the right technical decisions. You need an experienced engineer who's been CTO before — available when you need them, gone when you don't.
The problem
Most startups don't need a full-time CTO.
You need someone who can make architecture decisions that won't haunt you in 18 months. Someone who can evaluate developers, choose the right stack, and keep your technical roadmap honest. But you don't need that person 40 hours a week — and you definitely can't afford $200-350K in salary plus equity.
"A bad technical decision at the start costs 10x to fix later."
That's where a fractional CTO comes in. You get the experience and judgment of someone who's built and scaled products before — without the full-time overhead.

FAQ
Common questions
How many hours per week? +
Completely flexible. Some clients need 5 hours a week, others need 20. We scale up or down based on what your startup needs right now — no minimums, no long-term contracts.
Do you replace a full-time CTO? +
For early-stage startups, yes — we handle everything a CTO would. As you grow and are ready to hire a full-time CTO, we help you find them, onboard them, and transition out cleanly.
Can you also build the product? +
Absolutely. Unlike most fractional CTOs who only advise, we also write code and ship features. Strategy and execution from the same person means nothing gets lost in translation.
What if we already have developers? +
Great. We work alongside your existing team — setting architecture standards, doing code reviews, unblocking technical decisions, and mentoring junior engineers.
