Our backers include Matt Schlicht (founder of Moltbook), the founders of Crunchbase and Republic, and VCs including Draper, Precursor, and Liquid2. We're working at the frontier of autonomous systems, building agents that don't just chat, but run entire businesses. Our system identifies business opportunities through market signals, validates ideas with live ad tests, builds and launches software products, and brings in human experts wherever agents fall short.

Over the next 12 months, our focus is on reliability, throughput, and self-improvement, making every launch better than the last.

This is a highly technical leadership role that combines architectural decision-making with hands-on engineering.
