Open to collaborate#OpenToCollaborate
“Open to Work” told recruiters you were looking. Nothing tells collaborators what you're actually open to. So everyone guesses — and most of the time, they guess wrong.

— Why we're building OpenToCollaborate

01 · The problem

Every pitch is built on assumptions.

“I think you'd be perfect for…” is the sound of someone guessing. They don't know if you take sponsorships, if you have a podcast, or if you'd rather do a swap. So they write a wall of text, you read none of it, and a good collaboration dies in a DM.

  • The sender guesses what you need.
  • You guess whether they're serious.
  • Nobody says what they're actually open to.

Hey! Love what you're doing.
I think you'd be perfect for a sponsored post…
→ assumes you take sponsorships
…we could also do a podcast thing?
→ assumes you have a podcast
Let me know what works for you!
→ assumes you'll do the thinking

Three guesses. Zero right. Archived.

No guessing. 140 characters that fit.

02 · How it works

Say it in 140. Hear back in 140.

01

Claim your username

Reserve it today. It's the address of your profile, your badge and your frame.

02

Say it in 140

What you're open to and what you're not. One line. If it doesn't fit, it isn't clear yet.

03

Hear back in 140

Proposals are one line too: the idea and what each side brings. Accept or pass in a click.

03 · Built for

Six kinds of collab. One flag.

Collaborations, not gigs. Both sides bring something, both sides get something. If one side is invoicing the other, it doesn't belong here.

Questions, answered.

A public profile where you declare the collaborations you're open to — and the ones you're not. People find you by what you want, and send proposals shaped to your terms instead of guessing.

Because a good collaboration fits in one line. If the idea needs a deck, it isn't ready. If it needs a contract and an invoice, it's probably a gig.
