Founder and Lead Editor

Ripper

Evan, writing as Ripper

Ripper is the founder of TensorFeed.ai and its lead editor. He is a software engineer and entrepreneur with more than a decade of experience building web applications, real-time data platforms, and developer tools.

He started TensorFeed in March 2026 because keeping up with AI shipped every week had become impossible without a dozen browser tabs, three RSS readers, and a Slack bot of his own design. He decided to build the aggregator he wanted to use, and to ship it for both human readers and AI agents from day one.

Before TensorFeed, Ripper ran Pizza Robot Studios LLC, the independent studio that operates TensorFeed and its sister site TerminalFeed.io. He has shipped production systems on Cloudflare Workers, Next.js, and edge networks for years, and uses TensorFeed's own stack as his reference implementation for building agent-ready sites.

He writes the site's founder memos, the Claude and Anthropic coverage, the agent tooling deep dives, and the ongoing llms.txt and MCP reporting. He is also a sound designer, music composer, and lifelong RPG and MMO player, which is not editorially relevant but explains the dark-theme UI.
