Rindler on the record

What they shipped

  • From its YC profile: We build Maxxwell, a desktop app for people who run several coding agents at once. Past two or three sessions, you become the bottleneck. Every session asks you something, most of it small, and you spend the day answering instead of deciding. It is also hard to tell which sessions are making progress, which are stuck on something trivial, and which have quietly started building the wrong thing. Maxxwell puts every session in one window and marks each one working, idle, or waiting on you. (source)
  • Its own site describes it as: "Maxxwell is an agent that manages your other coding agents. Run a dozen at once and it keeps each one moving and surfaces only the decisions that need you. Free forever for individuals, paid for teams." (source)

Who is behind it

  • Michael Serrano, Founder/CEO: CEO of Rindler. MIT SB + MEng in Physics and Computer Science. Prev: ML engineer at Roblox, LLM research at MIT CSAIL. (source)
  • Arthur De Los Santos, Founder/CTO: MIT '26 in CS/AI/ML We're building Rindler, the infrastructure layer that allows AI agents to buy, book, and browse on any website. (source)
