Summary

Senior🎓
Top SchoolCliff Crosland is a seasoned founder and engineering leader with 15 years building high-scale data platforms and security infrastructure, currently CEO and co-founder of Scanner.dev, which makes petabyte-scale S3 logs instantly searchable and saves customers six- to seven-figure log costs. He previously led backend and data-platform engineering at Cisco and Accompany, shipping production systems in C++, Ruby, Rust, Java, and Scala, and helped scale people-graph and insights features used across Webex. Cliff combines hands-on systems design with product-driven execution—accelerating detection engineering projects by up to a year while avoiding re-ingestion and schema work. A pragmatic technologist who once co-founded fintech and loyalty startups, he’s unusually comfortable oscillating between low-level performance work and CEO-level strategy, and these days admits a mostly-loving relationship with Rust.
