Why this works for Boston

The local math

Boston is the deep-tech founder town in 2026. MIT and Harvard pipelines feed biotech, healthtech, and robotics. The catch: ML talent here is priced against $300K+ biotech offers, and your seed-stage budget doesn't compete. Different math — one named senior engineer plus AI agents, two-week first deploy, flat price.

Year-one outlay for a single senior hire in Boston: ~$290K. Our fractional cto engagement starts at $4,000.

FAQ

Common questions about fractional cto in Boston

How much of your time do we get?

Plans typically range 10–30 hours/month depending on scope. We're not your only commitment, but we set a fixed window every week that's yours — same day, same hours.

Is the price really flat?

Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

Can you hire engineers for us?

Yes — full hiring loop: writing the JD, sourcing channels (we have a network), screening, technical take-home design, final-round interview. Most CTOs we've helped hire run their first sprint inside a month of starting.

Will you keep coding if we hire a full CTO later?

Happy to. Many founders bring on a full-time CTO and keep us as senior IC for 2–3 months while they ramp. No ego — we'll happily report to whoever you hire.

Who owns the code?

You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
