Summary
🤩
Rockstar🎓
Top SchoolMark Hendrickson is a founder and product-focused engineer with 12+ years building consumer web and crypto products, now based in Barcelona leading Neotoma—a deterministic state layer that makes long-running AI agents auditable, versioned, and user-controlled. He combines hands-on product design and engineering with startup experience spanning founding exits, GM roles, and UX leadership at blockchain-focused teams like Hiro and Trust Machines. His work centers on sovereign systems where memory, data, and money remain local-first and inspectable, turning agents from forgetful tools into replayable teammates. Mark’s background as a writer and early web entrepreneur informs a rare mix of narrative clarity and technical rigor, and he operates Neotoma solo while integrating agents across email, finance, content, and product workflows. An early TechCrunch contributor and serial founder, he brings a pragmatic obsession with explicit state and user agency that underpins nearly two decades of building interoperable, trust-oriented platforms.
