# David Lanstein

> David Lanstein is the San Francisco-based co-founder and CEO of Atolio, a private, permission-aware enterprise search company founded in 2019. After beginning as a software engineer at Splunk and moving into sales leadership at Loggly and PagerDuty, he saw how institutional knowledge became harder to find as companies grew. Atolio turns that operating lesson into infrastructure: it indexes information across workplace systems, uses organizational context to rank answers, and can run inside a customer's own cloud or on-premise environment. The company announced $24 million in total funding in September 2025 and later secured a $1.25 million U.S. Air Force SBIR Direct-to-Phase II contract.
