Stacksquare is an events organization for founders, investors, and operators. We host fireside chats, expert sessions, and peer gatherings in small rooms, and read every conversation through four lenses: stack, capital, strategy, and psychology.

The manifesto
There’s a specific kind of conversation that only happens in person. The one that actually changes something.

What we host
01
Fireside chats
One guest, live questions, no podium. The conversation you wish the panel had been.
02
Expert sessions
A practitioner walks through what they actually do, and takes it apart with the room.
03
Peer gatherings
Founders, investors, and operators around one table. Small enough that everyone talks.
The next room is forming.
Rooms stay small by design. One expert in the middle, four lenses on the table, and seats that go fast.
