What does Conway Research do?
Conway Research is an applied AI lab founded by Sigil Wen (creator of the Web 4.0 manifesto and a Thiel Fellow) building efficient frontier models and inference engines for on-device personal AI. Its flagship product, Underdog, runs private AI models (including the 4B-parameter 'Woof' and 'Underdog 27B') entirely on consumer hardware like Macs and iPhones without sending data to external servers. In October 2026 the company announced backing from Andreessen Horowitz, Khosla Ventures, Hummingbird Ventures, and Anthology (Anthropic/Menlo Ventures), among other investors.
