Preview: the Brotherhood app on an iPhone, showing a founder profile in Discover.

A founder profile with prompt answers and photos you can like one by one. The match screen: It's a build — you and Maya want to build together.

IThe Match

The right co-founder.

Browse founders the way you'd want to meet them: real work history verified through LinkedIn, prompts that show how someone thinks, and the skills they're missing. A match only happens when you both say yes.

  • Verified profiles, imported from LinkedIn
  • Filter by stage, skills, industry and city
  • Mutual match. No cold DMs, no noise.
Sharehouses: house groups, a map of listings and a smart lease ready to sign. A smart co-tenancy lease with rent split, equity clauses, chores and exit terms.

IIThe Houses

A house full of builders.

Live with people who keep the same hours. Form a house group with founders you've matched with, find the neighborhoods that work for everyone's commute, and sign a smart lease right in the app.

  • House groups and sharehouse chats
  • Listings mapped around your whole group
  • Smart lease: rent split, chores, exit terms
The funding directory: grants, fellowships, accelerators and VCs with deadlines and terms. The pitch shelf: startups seeking funding, with stage, traction and team size.

IIIThe Capital

Capital that already knows your name.

Skip the cold-email lottery. Browse 39 real funding programs, from grants and fellowships to accelerators and funds, each linked to its official application. Then put your pitch where investors on Brotherhood can find it.

  • Grants, fellowships, accelerators and VCs
  • Filter by type, stage and region
  • A pitch shelf built for investors

Questions, answered.

When does Brotherhood launch?

We're putting the finishing touches on the app now. Early-access members are invited first, in waves, ahead of the public launch on the App Store and Google Play.

How much does it cost?

Joining is free, including matching, house groups and the funding directory. Optional Plus and Pro memberships add extras like unlimited likes and advanced filters.

Who is it for?

Early-stage founders from idea to Series A, anyone looking to become a co-founder, and the angels and micro-VCs who back them.

Where is it launching?

City by city, across startup hubs in the US, Canada, the UK and Australia. Add your city when you sign up. It helps us decide where to open next.

What do you do with my details?

We use them only to invite you to Brotherhood and send launch updates. We never sell them. Reply to any email from us, or write to admin@builderbrotherhood.com, and we'll remove you.

Your details, in plain words

When you request early access we collect your first name, email, city (if you add it), whether you're a founder or investor, your phone type, and which link brought you here.

We use them for one thing: inviting you to Brotherhood and sending launch updates. We don't sell them or share them with advertisers. They're kept on our web host and in our email inbox.
