A co-founder pool or a match you describe to an AI

YC Co-Founder Matching does one job: it helps you find a co-founder. It caps your outreach at 15 invitations a week. You tell its AI the co-founder, investor or adviser you need, and it suggests eligible Omnitwine members who fit, each with a reason. Both are free, and both leave the decision to connect with you. ^[8]

When YC Co-Founder Matching fits best

Choose YC if you want a co-founder specifically and can wait up to a week for approval. The Startup School course and the in-person meetups add structure that Omnitwine’s terms don’t describe. A match forms only when both founders accept, and YC publishes its rules in the Startup School FAQ. ^{[2] [3] [6]}

When Omnitwine fits best

Choose Omnitwine when you need an investor or an adviser alongside a co-founder search, or when you can describe a co-founder in a sentence and want suggestions from eligible members. Its AI suggests members who fit, each with a reason, and you decide whether to connect. Signed-in members can also browse its member directory yourself. It lists every member's name, email and LinkedIn. ^{[5] [8] [7]}

What each one doesn’t do

YC doesn’t hire, sell services or promise a match, and joining doesn’t improve your chances of getting into YC. Omnitwine doesn’t verify identity, skills or credentials, and it isn’t a job board or a payment service. No match or reply is guaranteed. Its network is young, so who you can reach depends on who has joined. ^{[2] [6] [8]}

Using both

The two can run side by side. A founder can run a co-founder search on YC and use Omnitwine for an adviser or an investor. On Omnitwine, assume that other signed-in members can see your name, email and LinkedIn profile before you connect with anyone. ^[7]
