Jam.gg, founded in Paris in 2020 as Piepacker and rebranded in 2022, built a browser-based social cloud gaming platform for playing retro and indie multiplayer games with friends with no download or install, on patented streaming technology the company said cut bandwidth requirements by roughly 15x. It passed 8 million users before pivoting to selling its cloud gaming technology B2B to game developers and publishers. Backed by Makers Fund, Serena Capital, LEGO Ventures, Kima Ventures and Kickstarter (~$15.4M raised) and a Y Combinator W20 company. Jam.gg never published an HTTP API: its developer surface was a native game-integration SDK plus a Compose Multiplatform virtual gamepad library, both shipped from the GitHub organization still named piepacker. Y Combinator's company directory now lists Jam.gg as Inactive, noting the business split into two entities in 2023 with Onibi emerging separately; the jam.gg web property no longer completes a TLS handshake and piepacker.com has left DNS.
