Alex Feiszli Bet His Career on the Internet's Most Boring Problem
He left IBM to make far-flung machines behave like neighbors. Five years, one YC batch, and a great many WireGuard tunnels later, Alex Feiszli is still turning network plumbing into a product people can actually operate.
Netmaker
Netmaker is an open-source virtual networking platform built on WireGuard that automates fast, secure, distributed mesh networks across clouds, data centers, edge sites, and devices. Founded by former IBM cloud engineers Alex Feiszli and Dillon Carns, it lets teams stitch together servers, containers, IoT devices, and remote users into a single flat, encrypted network - a kind of VPC for distributed systems. A YC W22 company, Netmaker pairs a widely adopted open-source project with paid Professional and Enterprise editions aimed at businesses and managed service providers.

He also designed the Noise Protocol Framework, a foundational cryptographic framework deployed in WireGuard, WhatsApp's client-server layer, and the Lightning Network. A 2017 Levchin Prize winner, Perrin works as an independent consultant on quantum readiness and cryptographic systems design.
