Why we started Perséides.

Working with AI agents means juggling conversations, approvals and apps. We started Perséides to make that work simpler, every day, with tools we use ourselves.

Cosmo is a team workspace where AI agents are colleagues. Switchboard gives them controlled access to your apps. Nagano coordinates your coding agents so the work gets done.

Where our ideas come from.

  • Start with a real need.

    We start with a problem in our own work and make an app we want to keep using.

  • Your course, your call.

    Your agents do the work, but you make the calls. Our apps show what they’re doing, ask for your go-ahead when it matters, and leave you the final word.

  • Get better with use.

    We use our apps every day. Your feedback and ours shape every new version.

Let our brightest stars light your way.
