DoxxNet founder Barrett Lyon is building a 196-domain mesh for private peer-to-peer calls, chats, and 20 GB file transfers.
a16z’s Joel de la Garza talks with DoxxNet founder Barrett Lyon, whose path to building privacy infrastructure included a near-fatal engine failure over Oakland: after losing most engine power, he landed safely at Buchanan Field, later tracing the failure to three cascading faults. Lyon says internet protocols have stagnated and argues that VPNs only mask entry and exit points while leaving users dependent on servers they may not control. DoxxNet’s parallel mesh spans 196 domains and supports encrypted, direct calls, chat, and file transfers up to 20 GB without a central application server. The company says it operates 26 sites with 12 people, using locally run AI instead of network administrators. Lyon also warns that aggregated ad-tracking data can reveal intimate life patterns, and disputes claims about data centers’ water use. The conversation closes with his earlier cyber-defense work at Prolexic, Russian cybercriminals, and network artwork in MoMA’s collection.
