Cinder

Cinder raised a $41 million Series B on 12 May 2026, led by Radical Ventures with Accel, Y Combinator, M12 (Microsoft's Venture Fund), PSP Growth, and Neuberger's Outpost Ventures also participating (Cinder press release; TheSaaSNews). Its named customers include OpenAI, Spotify, Depop, and Black Forest Labs, who use Cinder to detect and enforce against abuse in real time. The company was founded in 2022 by CEO Glen Wise, a former CIA cyber analyst and Meta Threat Discovery engineer. For someone weighing an early-stage infrastructure company, a fresh institutional round plus a named roster of AI-lab customers is a more checkable signal of durability than the pitch alone, though role scope and structure are typically still being defined this early in a post-Series-B company.
