Co-founder matching, in person

Find the person your startup is missing.

Missing Seat matches founders with the people who want to join them. We screen both sides, match them on paper, and bring them together for an evening of one-to-one conversations.

Who it's for

Two sides of the same table.

Founders

You have the idea. You're missing one person.

You have a startup or a serious idea, and you know which role is empty. Tell us who you need, and we seat you across from people who can fill it.

  • Matched on the role you need, your hours and your industry
  • Ten conversations in one evening
  • No pitching to a crowd

Sign up as a founder

Joiners

Don't start a startup. Join one early.

You have skills a young company needs, and you'd rather build with someone than start from zero. Meet founders looking for exactly what you bring.

  • Students, career switchers and seasoned professionals
  • Matched on your skills, interests and time
  • See startups from the inside before they hire

How it works

From sign-up to introduction.

One short form. We do the sorting, you do the talking.

1

Tell us your side

About four minutes. Founders name the role they need. Joiners say what they bring.

2

We match on paper

Role needed against skills offered, then hours per week and industry.

3

Meet one-to-one

Two rounds of eight-minute conversations. Founders stay seated, joiners move.

4

Mutual yes

Tick who you want to see again. We share contacts only when both said yes.

Not only developers.

Most early teams are missing someone who doesn't write code. These are the roles founders ask for. If yours isn't here, you can write it in.

Questions

Before you sign up.

Do I need a technical background?

No. Founders look for marketing, sales, finance, legal, operations and design as often as for developers.

Do I need my own startup idea?

Founders need a startup or a serious idea. Joiners don't. That's the point of their side of the table.

Is this a job fair?

No. Founders look for a co-founder or an early team member, and many offer equity rather than a salary. Each founder tells us what they offer, so it's clear before you sit down.

I bought a ticket on Eventbrite, Luma or Meetup. What now?

Go to Have a ticket? and fill in the same short profile with your order number. We need it to match you. You don't pay again.

What happens with my answers?

We use them to match you for the evening you signed up for. Your name and LinkedIn go to someone else only after a mutual yes. You decide separately whether we keep your profile for future evenings. Read the privacy notice.

Can I get a refund?

Tickets are non-refundable. If your side is full when you sign up, you join the waitlist and only pay when a seat opens.
