We’re excited to announce Blake Scholl as a speaker at Startup School 2026.

Blake is the founder and CEO of Boom Supersonic. He started the company in 2014 with a background in software engineering — not aerospace — and set out to build the world’s first economically viable supersonic airliner. Last year, Boom’s XB-1 demonstrator completed its supersonic flight test campaign, becoming the first independently developed jet to break the sound barrier. The full-scale Overture airliner has pre-orders from United, American, and Japan Airlines.

It’s exactly the kind of wildly ambitious technical company we want more of. Blake will be with us in San Francisco on July 25–26.

We're entering a new era of software where a single person, working with AI agents, can build products that previously required entire teams.

In this episode of Lightcone, the hosts break down the rise of AI coding agents, "tokenmaxxing", and the emerging workflows behind tools like Claude Code and OpenClaw. They discuss why AI systems today feel less like productivity tools and more like collaborators, why the future of AI should be personal and user-controlled, and how founders are starting to build software in completely new ways.

Most AI chips are designed for “prompt in, response out.” Agents don’t work that way. They loop, branch, and hold context across dozens of steps, and current GPUs hit 30–40% utilization because of it.

That gap is where purpose-built silicon wins.
