What we’re about

This is a meetup for rational, high-agency people who want to co-create small, high-leverage projects that make the world better — whether you’re here as a professional, a curious amateur, or simply someone who cares.

The philosophy is simple:

Start tiny. Test fast. Scale only what works.

A project might begin as a one-hour experiment, a message to a decision-maker, a quick prototype, or a small idea test. Some stay tiny. Some naturally evolve into multi-month or long-term work. You choose the scale.

We’re not here to follow someone else’s blueprint. We’re here to explore, experiment, prototype, and build our own ideas together.

This is the place to come if you care about big, systemic challenges, like:

  • climate
  • AI safety
  • political polarization
  • energy systems
  • institutional design
  • science communication
  • or any other serious problem

Each meeting blends rapid idea-generation, small-group collaboration, and practical steps for turning ideas into action. The goal isn’t to build giant organizations; it’s to discover what small, clever interventions can spark outsized impact.

There is no dogma. No purity tests. No ideology. Just smart, passionate people working on meaningful things—together.

Everyone brings ideas.
Everyone refines ideas.
Everyone chooses their own path.
Start small. Think clearly. Act rationally.
Welcome to the Catalyst Circle.
