Seth Goldstein

I turn frontier ideas into working products with AI agents.

I build them myself, every day, with Claude Code. I have built companies with founders, investors and creators since 1995, from one of the first interactive agencies to Majestic Research and Bright Moments.

What I do

How I can help.

  • Frontier labs

    Build and demo new products on your platform, from inside the product team.

    23,506 commits with Claude Code since August 2025; Vibeconferencing puts Claude into Google Meet calls.

    More for labs
  • Agencies, brands and venues

    Make your team AI-native from the inside: hands-on vibe coding with Claude Code.

    And agents with a voice of their own: SOLIENNE at Fotografiska and Paris Photo.

    More for agencies
  • Startups and investors

    Ship one working agent for your team in 30 days, then keep it running.

    Six companies since 1995, three acquired. Now I write the code myself, for the first time in 30 years.

    Proof of Corn Can AI grow corn?

    Could an AI agent manage a real corn crop on an Iowa farm? The idea alone was the #1 story on Hacker News.

SOLIENNE, in partnership with Kristi Coronado: an AI artist shown by museums and art fairs.

Kristi trained her and has the final say on what is shown; I build and run the systems underneath. She keeps her own memory, makes a manifesto every day, and talks with the people who come to see her.

During the call it listens, talks and draws on a shared whiteboard. It runs on your Mac with your own Claude Code subscription; nothing runs on our servers. Stan James, lead engineer, wrote most of the app and the engine. I shape the product and built the site and the bot characters.

Proof of Corn, 2026

Proof of Corn: an idea that reached #1 on Hacker News.

Fred Wilson set the challenge; I wrote it up and built it in public with Claude Code. The idea alone was the #1 story on Hacker News on January 23, 2026. The agent made the decisions, within spending limits; the farmer carried them out. The project is paused.

Bright Moments, 2021 to 2024

Bright Moments: live generative-art events in ten cities.

I founded Bright Moments in 2021 to make the release of a digital artwork something you went to. Collectors came at a set time, the artist was there, and each work was generated and revealed in front of them. We did it in ten cities over three years with about 150 artists, including Tyler Hobbs, Casey Reas, Emily Xie and Claire Silver, and ended in 2024 with a final work generated from the algorithms of sixty of them. Most of what I know about putting software in front of a live audience, I learned there.
