Transforming marketplaces

We build the infrastructure that lets small teams run marketplaces the way the largest ones do.

Proper started as an internal billing service for a two-sided rental business. The problem was never the payments — it was everything that had to be true before a payment could happen safely.

Identity, payouts, disputes, tax and trust all had to agree with one another, and each one lived in a different vendor with a different idea of what an account was. Reconciling them by hand cost more than the transactions were worth.

So we wrote the layer we wanted to buy. Today it runs for several thousand operators who would rather spend their attention on supply and demand than on ledger drift.

Our thesis is simple: marketplaces fail on operations far more often than they fail on demand. The founders we work with rarely run out of buyers first. They run out of the ability to settle correctly, at volume, without a finance team.

Onboarding and payouts that clear the same compliance bar in every market you sell into.
A ledger that survives refunds, split fees and partial cancellations without a spreadsheet reconciling it afterwards.
Dispute handling that a support agent can run end to end without escalating to engineering.

None of this is glamorous, and none of it appears on a landing page. It is, however, the difference between a marketplace that can enter its fourth country and one that quietly stops at two.
