​You've heard of accelerators. Have you heard of a Decelerator? ​Every year, promising climate startups wind down. What disappears with them: years of experiments, materials data, process notes, dead ends worth knowing about, and hard-won tacit knowledge. The next team starts from zero. ​The Decelerator, a new program from The Engine, works with founders of climate ventures that are winding down or pivoting significantly to turn what they learned and built into a public, searchable repository other founders and researchers can build on. Founders decide what's shared. ​Capital already invested in hard science shouldn't create value only when a company succeeds. A more efficient climate ecosystem saves time, and time is the constraint that matters most. ​We'll be in New York for Climate Week. Come talk about it over coffee. These are casual, drop-in office hours: stop by anytime between 9 and 11, ask questions, share your perspective, or just say hello. ​What to expect ​A relaxed, come-and-go format, no agenda, no pitch. First cup of coffee on us. ​Time with some of the team behind the Decelerator. ​Open conversation about where this could go. ​Who should come Accelerators, ecosystem innovators, investors, founders facing a wind-down (or anyone who knows one), and anyone curious about turning company closures into building blocks for future climate breakthroughs.
