Someone whose ambition matches yours, who takes the work seriously, and who you trust to solve hard problems together. C2FM is how you find your co-founder — on purpose.
APPLY TO JOINProximity. Timing. Whoever happened to be in the room. That's how most startups decide who to build with.
C2FM exists because that's not good enough.
C2FM is NYC's climate co-founder matching platform. A curated community of technical and non-technical operators, founders, and climate-serious professionals, brought together through intentional in-person experiences and online matching. All Access Membership starts at $20/mo.
Intimate breakfasts and dinners with operators, founders, and investors a few years — and a few hard lessons — ahead of you. The questions you haven’t thought to ask yet, answered by people who’ve already lived them. Flatten the curve before you start climbing it.
Bi-monthly speed matching curated by C2FM’s algorithm across technical depth, domain focus, readiness, working style. By the time you walk in, the work of narrowing the field has already started. Plus, members get weekly curated match drops between events, so the matching doesn’t stop when the evening does.
Chemistry isn’t chemistry until you’ve actually worked together. Hackathons and casual build nights where matched pairs test real compatibility in action. Members get one place to track all their matches, plus a community Slack to post needs, trade resources, and stay in the work between events.Ready to see where you land in the matching process?

C2FM is for people who are all-in on climate and ready to expand beyond who they already know.
The operator who keeps circling back to the same problem. The exited founder who's ready to go again. The researcher who's done working inside someone else's vision. The professional who has spent years in climate and is ready to build their own venture.
Every year, New York produces serious climate talent — researchers, operators, engineers — who can't find each other. C2FM is the infrastructure that changes that. The intentional moments where co-founder discovery begins on purpose, and the best climate companies start with the right decision: who to build with.
“[He] and I met and want to pursue this startup. Like I've never been more pumped to do anything.”

C2FM (Climate Co-Founder Matching) is NYC's climate co-founder matching platform. We drive climate startup formation through curated in-person events and an online portal powered by our proprietary founder matching algorithm. Every member is vetted, climate-serious, and ready to build.
C2FM is for climate-serious professionals in the NYC area — operators, founders, engineers, scientists, and domain experts who are all-in on climate and ready to find a co-founder. You can already have an idea, be actively building, or be exploring which problems in climate you want to solve. We started with the Columbia community and have expanded to include the broader NYC climate ecosystem.
We're looking for climate-serious intent, relevant skills or domain experience, and readiness to build with someone. You don't need a polished pitch, a deck, or even an idea — but you do need to be genuinely planning to start a climate company, with the time and commitment to actually do it. We also pay close attention to the intangibles: how you work, what you value in a partner, and what kind of co-founder dynamic you're looking for. Skills are table stakes — fit is what makes a company actually work.
C2FM is for founders and future founders — people whose plan is to start a climate company, even if they're not building one this month. Where you are in that journey shapes how you'll use the platform. Earlier-stage members get the most out of Learn events and browsing the portal while they sharpen their thinking. Members closer to actively building lean into speed matching and Build events. What we're not is a casual networking community — every member has founding intent.
Skills and experience are the starting point, not the whole picture. Building a company with someone is closer to marriage than hiring — you can have the perfect technical fit on paper and still fall apart six months in if your working styles, values, or risk tolerance don't align. C2FM is built around that reality. Our matching algorithm weighs the intangibles alongside the obvious stuff: how you make decisions, what you need in a partner, what dealbreakers you have, what kind of dynamic energizes you. Every member fills out a detailed profile, and our IRL events and weekly portal matches surface people who complement you across all of it — not just the skills column.
Co-founder discovery takes time — most members don't find their match at the first event or in their first batch of portal matches. The members who get the most out of C2FM treat it as a months-long process: showing up consistently, building relationships, and learning what they actually want in a co-founder along the way. Some members match within weeks; others take six months or more. The platform works best when you're patient and active.
We host a few public events throughout the year for people who want to get to know C2FM before applying — keep an eye on the events page. But almost all of our programming is members-only. To access the full slate of Learn, Meet, and Build events, you'll need to apply and be approved. Events are RSVP-based, so membership doesn't guarantee a spot at every event.
Yes, membership is $20/month, and it comes down to two things.
The first is access. You get weekly curated match drops, members-only events, our community Slack, and a curated network of serious climate builders across NYC. All C2FM events are free for members, and most are kept small, so RSVP early to grab a seat.
The second is that the fee filters for serious builders. It keeps the community full of people who are genuinely in it to build in climate.
If you're a serious builder and the $20 a month just isn't affordable for you right now, email me at sammie@c2fm.network and we'll work it out.
No. C2FM is private and accessible only to approved members. Your profile is never shown publicly or to non-members.
