SHARE MONEY · SPEND TOGETHER Spend and share money together.
Financial infrastructure for communities. Brook is the easiest way for a group to collect, manage, and use money together. Don't just give, participate in what happens next.
Brook is in early access. We're onboarding a small group of communities to share and spend money together — join the pilot to get early access and help shape what we build.

HOW COMMUNITIES SHARE TOGETHER
People share money in funds.
A fund lets people share money together, set spending boundaries, and see exactly how it's used. Share with a person, group, or project.

A STORY FROM BROOK
Michael's roommate fund, told as it happens.
"It was so easy to spend on our Brook card. No reimbursements, we always are on the same page, no more Venmoing back and forth. We have been using it for months and LOVE IT!"

FREQUENTLY ASKED
Questions we hear a lot.
Is Brook really free?
Yes — giving from your shared balance is free. Credit card contributions carry a standard processing fee, which we pass through at cost; Brook makes no money on it.
Where is my money held?
Funds are held by First Internet Bank of Indiana, an FDIC-insured U.S. bank.
Is giving tax-deductible?
For funds run as charitable causes through Brook's 501(c)(3) structure, contributions are tax-deductible to the full extent allowed by law. Personal funds (like sending money to a family member) are not deductible.
What happens if a fund doesn't use all its money?
The fund creator can return unused contributions to the people who gave them — or roll them into a related fund. The money never disappears into "platform fees."
Can I see a fund without contributing?
Yes — if the fund owner invites you. Brook funds have flexible visibility: from fully public to invite-only.
