How it works

A new way to back American businesses

Four reasons the Blast Furnace is built differently — for the founders raising and the investors backing them.

Foundry-reviewed

Every raise passes our operator-led diligence before it ever reaches the floor.

Open to everyone

Reg CF and Reg A+ structures mean you don't need to be accredited to take part.

Real ownership

Back the businesses you believe in with equity, revenue shares, or notes — not vague promises.

A guild around the deal

Members get founder AMAs, deal memos, and the Forged Network to scale post-raise.

Three stages of the fire

Every deal moves through the furnace

Spark — the open call

Founders pitch the guild. The community votes the most promising raises forward to Foundry Review.

Foundry Review — operator diligence

Directors and member operators pressure-test the model, the cap table, and the founder before anyone invests.

Ignite — the live raise

Cleared deals open on The Blast Furnace floor with full memos, founder AMAs, and patient terms.

The Foundry Review pass meant I didn't have to be the smartest person in the room to feel safe writing a check. The operators already did the work.
