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.
What We're Looking For
Former founders only - we look EXCLUSIVELY for those who have started companies before
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?
$2B+ portfolio value created - built scale companies like 3Y Health, Berry Street
$1.5M+ seed capital on day 0 - you don't need to bring your own thesis or investors
True co-founder of the business - your voice, equity and contributions will be that of a true co-founder
6 survival rate to Series B - our playbook consistently outperforms industry averages
What You'll Do
Join an existing Cold Start venture as CTO and co-founder
Prototype and launch the product, leveraging our playbook and technical resources
Recruit and lead a world-class team
Build a category-defining company with enduring impact
We are in-person out of SF and NYC.
