About us

Built at Launch House

From Cardi B and Paris Hilton's former mansion — an a16z-backed accelerator where ambitious founders live and collaborate together. That's where Stub3 started: a crib full of builders coming together after being isolated during Covid to learn how Web3 could change the way creators could monetize their work.

A house full of founders

Launch House brought founders together under one roof to live, build and ship in the same week. Stub3's first prototype — a proof-of-attendance badge minted at a live show — came out of that environment.

We kept the same operating principle: build with fans and operators in the room, not in a spreadsheet.

Inside the house

From the crowd

Our founder has been to a lot of concerts

Stub3 was built by someone who spent years in the pit, in the seats, and in the parking lots. That archive of shows is part of why we believe every fan's history should be verifiable — and rewarded.

The stub, reinvented

Changing the way ticket stubs are used

A stub used to be a keepsake and nothing more. We turn it into a live data layer: verified attendance, a permanent fan record, and rewards that keep paying off long after the encore.

Infrastructure

We're building on Soneium

Soneium is an entertainment-first blockchain — a network designed around fandom, music, anime and creator IP rather than trading. That focus matters for us: collectibles need to be cheap enough to hand out free at a gate, fast enough to mint while a fan is still standing in line, and durable enough to prove attendance years later.

Every Stub3 badge is issued on Soneium, so a fan's history stays portable and verifiable across artists, festivals and platforms — and royalty-ready when the entertainment economy settles on-chain.
