Catalyst Community

Catalyst is a community of founders, builders, hackers & scientists

Build faster with the support, insight, and energy of people like you.

A Community Built for Acceleration

We’re not a typical event series. Catalyst is a curated space for serious builders, thinkers, and change makers to connect, grow, and create. Our vision is rooted in human acceleration and long term flourishing, not just through ideas but through tangible actions.

Values

Built around real connection

Catalyst is a startup community rooted in real-world connection. No noisy chats, no endless feeds - just focused time with people who build.

We meet in person

Everything starts face-to-face. Dinners, retreats, and deep conversations spark trust and clarity no screen can match.

Built to stay small

We don’t optimize for scale. We optimize for signal. Each gathering is designed for depth, not reach.

Quiet, intentional presence

We keep it simple. Updates go out via email or private channels. The rest stays offline, where real work happens.

Member-driven, not platform-led

No dashboards. No group chats. Members shape what happens next—we just help make it real.

Backed by those who build.

Invest or raise through Catalyst’s internal angel syndicate — a founder-first circle where capital moves through trust, not pitches.

Take on or Extend Advisory Positions

Join early teams where your expertise matters.

Being at the retreat with other founders created connections that feel way more meaningful and lasting than anything you’d get from a conference or event.
