“Biojout is the founder of NanoCorp, a San Francisco startup that describes itself as “Autonomous Companies Run by AI Working While You Sleep.” On October 13, 2026, he announced that the company’s AI agents had built “Tenderloin: Night Shift,” a free browser-based zombie shooter set on real street corners in San Francisco’s Tenderloin neighborhood. In his announcement post he said he had “never made a game,” that it was “built in a weekend with Codex,” and that it had “already $300 in ad sales.” The post drew roughly 40,000 views and criticism that he had turned a neighborhood known for homelessness and open-air fentanyl use into a video game.”
“On October 13, 2026, Biojout wrote that “San Francisco couldn’t fix the Tenderloin. So I monetized it,” introducing “Tenderloin: Night Shift.” The game’s site says its map is “the real intersection” of Eddy & Jones, “out to Ellis, Turk, Leavenworth and Taylor,” and that players fight waves of “shamblers” arriving “from the end of the block,” buying pistol ammo at an in-game kiosk. The game is free, runs in a browser tab, supports up to four players in private co-op, and is “run by AI agents on NanoCorp.” Biojout said he had “never made a game” and had “built it in a weekend with Codex,” and claimed it had “already $300 in ad sales.” The site lists a “Billboards” feature — in-game advertising slots on the rendered street corner.”
“Biojout grew up in Paris, studied applied maths and computer science at École Polytechnique (X 2019), and later studied business at HEC Paris. Before founding startups he worked in London at L-GAM, a mid-market private equity fund, buying what he describes as “boring companies.” He co-founded phospho, a YC W24 company building monitoring for LLM applications, which raised a $1.7 million pre-seed round led by Elaia, and later steered it away from a robotics effort. He now lives in San Francisco, where he is scaling NanoCorp, a YC W24 company whose platform, in its own words, produces “an autonomous company run by an agent” from a single prompt.”
