Ambush and the art of making complicated things work
Behind the AI promises sits a less glamorous job: making data, software, hardware, and people agree. Ambush has built its business around that difficult meeting.
Brett Adcock
Brett Adcock is a serial entrepreneur and founder of Figure AI, the humanoid robotics company valued at $39 billion after a $1B+ Series C in September 2025. Raised on a third-generation farm in central Illinois, Adcock built his first web companies at 16, co-founded and sold talent marketplace Vettery to Adecco for ~$100M in 2018, took eVTOL company Archer Aviation public on the NYSE at a $2.7B valuation, then pivoted to what he calls the hardest problem: building general-purpose humanoid robots. Figure's robots now work autonomously on BMW's production floor and have logged over 30,000 vehicles built. In 2025-2026, Adcock simultaneously launched Hark (personal AI hardware, $700M Series A at $6B valuation) and Cover (school weapon-detection tech). He is currently running three companies at once while publicly estimating his net worth at ~$19 billion.
