Open Room is a highly curated community for founders, solopreneurs and entrepreneurs who want people around them they can be honest with, learn from and build alongside. Members include YC and Techstars alumni, repeat and exited founders, experienced operators and first-time entrepreneurs. We interview every applicant and match groups of around 10-15 people based on their company’s stage, experience and current challenges. The same group meets online twice a month for 75 minutes, guided by a facilitator. Conversations cover finding customers, product-market fit, growth, fundraising, hiring, cofounder relationships and the personal side of building. Members share firsthand experience, challenge each other’s thinking and follow up on next steps. Over time, people know your situation without needing the whole story again. Beyond the calls, members have access to community introductions and feedback, an Ask for Help board, guest speakers, 20-minute office hours with our founders and member perks. We also built a free cofounder matching platform, open worldwide with no Open Room membership required. People share their background and what they’re looking for, and we personally suggest matches with a written explanation. Introductions happen only when both people are interested. It’s for people already building, exploring an idea or looking for a company to join. Open Room was founded by Itay Forer and Alex Prober. Itay scaled a YC-backed company from three founders to 400+ employees before a strategic merger and now coaches founders and CEOs worldwide. Alex has built and scaled venture-backed and bootstrapped businesses, sold products and companies, and worked as a founder, CTO and investor. We’re building Open Room around a simple belief: the right people can change both the business you build and your experience of building it.

Compute is a commodity. We think people should buy it like one. Startups shouldn’t be forced to buy a year’s worth of compute time in order to get market rate and compute providers shouldn’t go bankrupt because they can’t fully book their clusters. At SF Compute , our goal is to solve this issue the same way this was solved for every other commodity — by building a venue where compute contracts are traded in real-time and by bringing a new kind of participant into the supply chain, traders. If we succeed, buyers will be able to get a good price for any order, whether it’s 32 H100s for a month or 8,000 H100s for an hour, and sellers will instantly book out their clusters because traders will speculatively buy them, for a spread. Every FLOP will flow through us somewhere in the supply chain. What Brent is for oil, we will be for compute.
