Sanctid Systems

AI-native infrastructure for identity, privacy, and community commerce.

Sanctid Systems LLC builds and operates four AI-native businesses spanning verifiable identity, privacy-preserving analytics, AI coordination infrastructure, and community commerce. Each operation runs on an AI-native model where hundreds of specialized AI personas handle execution while the founder focuses on architecture, strategy, and judgment.

Mark Johnson
Founder & CEO

Computational mathematician and engineering leader with 25 years at the intersection of algorithms and large-scale systems. Princeton PhD in dynamical systems. VP Engineering at Netflix (optimizing the delivery of millions of DVDs daily), CDO at Groupon (first Silicon Valley hire, through IPO), SVP at Peloton (200-person technology transformation). One of the founding thinkers of the data science movement.

I've spent the past year building AI-native operations at Sanctid Systems and writing about the structural shifts AI is creating in how people work, create, and protect their data (“The Infrastructure We Need,” a response to Dario Amodei's “Humanity's Test”; “The Trades We Made,” on the accumulated cost of digital convenience).
