Founders get access to our 2 coworking spaces in Lisbon, so they can build and scale with the support of a community.
What began with web3 founders has grown into something bigger.
Today we back founders across tech, entertainment, and AI. €100M+ total funding raised. 110+ supported projects.
At Poolside, we invest at the earliest stages and work alongside founders: capital, introductions, and technical help when it counts.

and everything moves very fast, so they learned to ship under pressure

3. Adapt quickly.
Web3 moves fast. Narratives shift and yesterday's assumptions can become obsolete.
That comfort with uncertainty is valuable when building in AI.
2. Build for a small, technical audience.
Find the people who understand the problem deeply, build for them, and use their feedback to improve.
1. Ship in public
Web3 taught founders to build in front of an audience, share progress early, and let users see what's coming.
That translates well to AI, where the product and the market are evolving together.
A few founders at Poolside came from web3.
Some of the habits they picked up are surprisingly useful for building AI products. 🧵
