Before founding Arch, I earned an MBA and Master's in Environmental Science from Stanford, led global solar projects with 180+ employees, and was a management consultant at McKinsey, helping software companies scale. Ask me about my favorite cafes and brunch spots in SF! Sacha (Co-Founder & CTO) - Hi, I'm Sacha!

Originally from Belgium, I discovered my passion for climate tech after experiencing devastating fire seasons in Australia and California. With a dual M.Sc. in Engineering and Management, I thrive at the intersection of engineering, design, and strategy. My entrepreneurial journey includes both early failures (a Tinder-like app ahead of its time) and successes (a YC-backed company with 40+ employees).

Previously, I built AI tools enabling first responders to rapidly identify fire ignition zones, directly influencing my path to founding Arch. Interviews start the week of March 31st. 🌱 Ready to Make an Impact? If this sounds like you, we'd love to connect.
