Halcyon helps founders get new projects off the ground. We provide seed funding, introduce co-founders, and accelerate new ideas.

Halcyon believed in us early. They made grants to fund the research that led to Goodfire. Then they invested, introduced key early hires, and stood by us as a mission-aligned backer.

Halcyon was an early supporter and quickly provided seed funding and operational support to get Transluce off the ground. They serve an invaluable role in the ecosystem.

Halcyon is how I met my Fathom co-founders, as well as some of our funders and board members. Fathom wouldn't be what it is today without Halcyon!

Halcyon understood the importance of our work early on, and backed it up with a significant launch grant. Mike introduced our first key hire and later joined our board. Seismic wouldn't exist without their support.
