Cold Start Ventures is looking for exceptional CTO co-founders to lead new companies in our portfolio. Each venture is backed by tier-1 VCs with $1.5M+ in committed day-one capital. You’ll join as a true co-founder — with the equity, influence, and expectations that come with it. If there’s a fit, you’ll hear from us within 24 hours.
At Cold Start, we incubate companies at the intersection of healthcare and AI, built around deeply researched, conviction-driven theses. To date, our team has helped create over $2B in portfolio value, including breakout successes such as 3Y Health and Berry Street. Our ventures benefit from a tested playbook that drives a 6× higher survival rate to Series B than the industry average.

Structured training – experience in top-tier engineering environments (Big Tech or lage-stage startups)
Elite education – Undergrad CS or related degrees from top 20 universities
Bias toward action – hungry, resourceful, and relentlessly execution-oriented
Why Cold Start?
