5050 alumni are creating massive positive impact:


5050 is run by 50Y. We’re experts in deep tech entrepreneurship.
At Fifty Years, we’ve built deep tech companies ourselves. We’ve backed over 100 deep tech companies from the earliest stages and helped them raise over $4.6 billion. We've helped our founders achieve many “firsts”
the first carbon-negative molecule factory
the first cultivated meat approved in the U.S.
the first microgeo satellite for internet connectivity
the first in-orbit space factory that manufactured pharmaceutical drugs
the first de novo synthesis of a 1000+ base DNA molecule
and many more
We supported these founders when they barely had a working prototype. We backed Sean Hunt and Gaurab Chakrabarti when they had just built a janky prototype reactor with wood, PVC pipes, and zip ties from Home Depot. Solugen has now built a 63-foot-tall carbon-negative molecule factory that offsets over 30,000 tons of CO2 a year and is on the path to decarbonizing 90% of the chemicals humanity needs.
We backed John Gedmark and Ryan McLinko when Astranis was an idea on a whiteboard. They've now launched satellites, closed more than 1 billion dollars in contracted revenue, and are on the path to connecting 3 billion people to the internet.
Our 5050 alumni:
5050 was the fundamental catalyst for founding Huminly! Huminly would have had a very different start, if at all!
Office hours helped me focus on a select number of objectives I needed to hit to spin out of Stanford and fundraise. I remember Alex told me early on to focus on the polyester monomer and to meet the technical specs at a viable cost. That advice is something we’re now chasing at full speed!
Nikita Khlystov, co-founder of Huminly. Prev. Cochran lab at Stanford
Our team completed 5050, and we started Externa. We built our first pitch deck and negotiated our first client deal during 5050! The 50Y team gave us key advice when spinning out our startup. After 5050, the cohort has become a fantastic network to lean on.
Helena De Puig, co-founder of Externa. Prev. Collins lab at Harvard
The caliber of scientists that Fifty Years brought together was incredible. You gain insider knowledge you’d only gain if you talk to and share with peers who are also trying to figure out the entrepreneurial journey themselves.
Floris Engelhardt, co-founder of Kano. Prev. Bathe lab at MIT
Before 5050, the chances of us starting a company were ~10%. They’ll tell you if it’s a bad idea and help you land on something worth pursuing. Within weeks, we quit our jobs at Tesla, and we’re now building the startup full-time.
Niccolo Cymbalist, co-founder of Clippership. Prev. Tesla and PhD from Caltech.
We joined right as we were spinning out, and it's been a game changer. There were numerous times I heard a tip from a 5050 event and used the advice the next day at our company. It's run by former founders who really get it and have been there, done that.
Eric McShane, co-founder of Electroflow Tech. Prev. Cargnello lab at Stanford
As a mechanical engineer, bouncing ideas off a cohort with a deeply technical background in chemistry and biology expanded my sense of what’s possible. From working on a problem in manufacturing with no market opportunity, I pivoted to something I am deeply passionate about in the energy space.
Daniel Rahn, founder of MetalAF. Prev. SpaceX
Surrounding myself with incredibly kind and supportive scientists, founders, and 50Y team gave me the confidence to pursue entrepreneurial ideas that I otherwise would not have even considered exploring.
Erin Huiting, Bondy-Denomy lab at UCSF

Market forces reward shipping models faster over long-term human flourishing. Safety isn’t keeping up.
Make alignment the default path.
The 5050 experience
1. Identify civilization-scale problems that are good business opportunities.
5050 will help you answer: How do I turn research into a startup? How do I align commercial demand with a flourishing future? How do I recruit a world-class team? Am I the right person to do it?
We'll help you diagnose and mitigate risks, pivot quickly if necessary, identify the problem you can uniquely solve, and make a solid plan to commercialize your tech.
Does the idea chunk nicely into milestones? Is it too risky, or not risky enough? Is there a market for it? Do the technoeconomics make sense? Is your invention 10x cheaper, better, or faster than how things are done today?
2. Learn everything you need to start a deep tech startup.
We’ll host weekly entrepreneurship workshops. You’ll learn the best deep tech approaches to hiring, fundraising, selecting your co-founder, recruiting, engaging customers, achieving product-market fit, executing fast, and storytelling.
50Y Partners will meet with you weekly to give mentorship, resolve challenges, and set the pace for execution. Recognizing that every delayed solution can cost real lives and entire ecosystems, 5050 will help you quickly de-risk your technology, hit milestones, raise your first round, and avoid costly mistakes.
3. Grow into a great founder.
We’ll help you figure out if entrepreneurship is for you (it’s not for everyone!) and coach you through the early days of your startup. You’ll meet successful deep tech founders and learn what the early days of building a startup look like.
Personal growth workshops will push past your edge and help you develop traits all great founders share: thinking against the grain, studying the greats, high expectations, speed, optimism, audacity, risk-taking, relentlessness, work is life, and resourcefulness.
4. Join a community of future deep tech founders.
You’ll join a cohort of ambitious scientists, engineers, and builders tackling the world’s most pressing problems. Building alongside entrepreneurial peers will challenge you to level up and provide a community to lean on for support. Since you’re navigating the entrepreneurial journey together, it’s almost guaranteed someone in your cohort has just solved the challenge you’re facing right now.
5050 alumni, many of whom are now deep tech founders, are eager to share their experiences with you.
5. What? When? Where?
Our next cohort runs from September to December.
We’ll fly the entire cohort to SF for the kickoff weekend (early Sept) and a 3-day off-the-grid experience (Oct 24 - 26). After the kickoff, every week you’ll join office hours with 50Y Partners and afternoon workshops focused on essential entrepreneurship skills. Workshops are held in-person in SF and Boston, and remotely for participants across the rest of the US.
