Two-sided marketplaces,
built past the demo.
Supply onboarding, search that matches, payments that split correctly and the admin tooling your ops team lives in. Built on a foundation that survives your first thousand transactions.
What it is
What marketplace development actually involves
A marketplace is two products wearing one brand. Supply needs onboarding, listing management and a payout they trust. Demand needs search, comparison and a checkout that does not lose them. Both sides need to believe the other is real.
The hard parts are rarely the listing pages. They are the money and the trust: splitting a payment three ways and getting the accounting right, holding funds until delivery, handling refunds and chargebacks, and giving your ops team the tools to intervene when something goes wrong.
What we build
Both sides, and the machinery between.
The parts that decide whether a marketplace works after launch, not during the pitch.
Search and matching
Filters, ranking and relevance that fit your category, with the indexing to keep it fast as inventory grows.
Payments and payouts
Split payments, escrow where the category needs it, refunds, chargebacks and the reconciliation your finance team will ask for.
Trust and safety
Reviews, dispute handling, fraud signals and the moderation queue that keeps a marketplace usable.
Ops and admin
The internal tooling your team needs on day two: impersonation, manual overrides, refunds, audit logs.
Analytics
Liquidity, match rate, time to first transaction. The numbers that tell you whether the marketplace is actually working.

Common questions
Marketplace questions we get first.
Not answered here? Email us. A real reply from an engineer, no form.
How do you handle the cold start problem?
That is a business problem before an engineering one, but we build for it: bulk supply import, seeded listings, and manual matching tools so your team can close the first transactions by hand while liquidity builds.
Can you do split payments and payouts?
Yes. Split payments, held funds where the category needs escrow, scheduled payouts, refunds and chargebacks, with reconciliation your finance team can actually use.
Do we need escrow?
It depends on the category and the delivery risk. High-value or delayed-delivery categories usually do. We map the money flow with you before writing any of it.
What does a marketplace cost to build?
It comes down to how many of the pieces above you need at launch. We scope it and give one fixed number. Most first versions cut trust and safety back and keep payments complete, because money bugs are the expensive ones.
Who owns the code?
You do. Repos, infrastructure, payment accounts and third-party services all transfer on day one and stay in your name.
