How this works
One AI-native engineer.
The output of a team.
One senior engineer plus AI agents now ships fractional cto that used to need a four-person team. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in Boston who need to ship before the next round closes.
The local read
Why fractional cto is hard in Boston
Boston founders have access to the best deep-tech talent in the country and almost none of it is hireable at seed stage. Biotechs pay above market for ML engineers. Cambridge robotics shops pay close to that for ROS 2 specialists. The local agency option is mostly enterprise consulting with multi-quarter contracts.
We're not enterprise consulting. One senior engineer owns the build, Eastern Time, overlap with your MIT advisors and Boston-based investors. FHIR or HL7 for healthtech. PyTorch and Hugging Face for ML features. Next.js for the SaaS layer. Flat-price quote in 24 hours. Code in your GitHub from commit one.
Hiring one senior leader here is a ~$290K year-one outlay and a 60–90 day search. Our fractional cto engagement starts at $4,000 with a first deploy in Monthly engagement.
