We're a 5-person team in SF (YC W26). Aryan and Jai met on day one at UC Berkeley and finished EECS/CS in 2.5 years. Aryan was a military officer in the Singapore Armed Forces. Jai published research at Stanford at 16 and worked as a SWE at 5 startups. We recently hired an ex-YC founder and would love one more onboard.
