How it works
-
1/7Your profile
Say what you build and what you're missing
Specialties, starting point, availability and ambition. You don't need anything built: you may not even have an idea yet. Answer one or two short questions so people can see how you think.
-
2/7Tap to see more
Every card has more than one page
One tap on the card moves to the next block: what they're looking for, when they work, where they're starting from and their answers.
-
3/7Swipe
Like or pass, no fuss
Right if you're interested, left to move on to the next person. Nobody knows who you passed on.
-
4/7The deck buttons
Four shortcuts under the card
- Super Like Tell them you're really interested. It stands out more than a like.
- Undo Bring back the last profile you passed on. It's a Premium feature.
- Boost Your profile shows up sooner for 30 minutes. It's a Premium feature.
- Filters Search by specialty and time zone. The other filters are Premium.
-
5/7Match
When the interest is mutual, it's a match
You can only talk to people who liked you back. When you match, a private chat opens between the two of you.
-
6/7Chat
Talk and see if you click
To break the ice, the app suggests a few questions to start with. Nobody hires anybody here: you're peers and you decide together.
-
7/7Groups
Join a project or start your own
Beyond one-to-one matches, you can form a group of up to 6 people whose skills complement each other, see who's in and talk in the group chat.
Frequently asked questions
Is it free?
Yes. Creating your profile, swiping, matching, chatting and joining groups are free. Premium is optional and adds unlimited likes, undo, seeing who liked you, Super Likes, Boost and advanced filters.
How old do I need to be?
cofounder is for people aged 16 and over. Read our child safety standards.
Is it a dating app or a job board?
Neither. It's for finding someone to build something with as equals: nobody hires anybody. We don't offer legal advice or funding either.
Do I need an idea already?
No. You may have no idea yet, one you haven't started or have tried something small. You say so on your profile and meet people at a similar point.
When can I download it?
Very soon on the App Store and Google Play. Once it's out, the buttons on this page will take you straight to the store.
How do I cancel Premium?
From the store you subscribed in: on iPhone, in your Apple account settings → Subscriptions; on Android, in Google Play → Payments & subscriptions. Deleting the app doesn't cancel the subscription.
How do I delete my account?
In the app, under Settings → Account. If you no longer have the app, follow these steps.
What do you do with my data?
Only what's needed for it to work: your profile, your matches and your messages. Your photo is optional and only goes public after an automatic safety review. We don't sell data. The details are in the privacy policy.

Your other half is looking too. Get cofounder and start swiping.
