Marketplace Development

Marketplace development for two-sided platforms that need to scale

Two-sided platforms engineered for trust, scale, and unit economics — supply onboarding, demand discovery, payments, payouts, and operator surfaces.

Capabilities

What we ship

Two-sided platforms touch every hard problem in B2B engineering: payments, KYC, search, fraud, and operator tooling. We have shipped each piece in production at scale.

  • Supply-and-demand onboarding flows with KYC, KYB, and verification
  • Marketplace payments: Stripe Connect, Adyen for Platforms, custom orchestration
  • Search and discovery surfaces, ranking, and personalization
  • Dispute, refund, and chargeback handling end-to-end
  • Operator dashboards for trust, safety, and fraud teams
  • Ratings, reviews, and reputation systems
Supply and demand

A marketplace is two products that have to balance

The supply side and the demand side need different surfaces, different metrics, and different operator workflows. We build both halves so they grow together.

  • Supply onboarding with KYC, KYB, and document verification

  • Demand-side discovery: search, filtering, ranking, personalization

  • Trust and safety: ratings, reviews, dispute handling, fraud signals

  • Marketplace payments: held funds, scheduled payouts, multi-party splits

  • Operator surfaces for moderation, support, and growth teams

  • Cross-border payouts, regional compliance, and currency handling

Outcomes

Outcomes that prove the marketplace is healthy

A marketplace works when supply and demand both grow without operator intervention scaling linearly. These are the outcomes we hold ourselves to.

  • Time-to-first-transaction under 7 days for new supply-side participants
  • Marketplace take-rate visibility with audit-grade ledger reconciliation
  • p95 search latency under 200ms across catalogs of millions of listings
  • Dispute resolution times cut by 50% with structured case management
  • Multi-region payout support without per-region code rewrites

Marketplace FAQ

What founders ask before launching a marketplace

Do you build marketplaces from scratch or extend existing ones?
Both. Greenfield marketplaces where we own the architecture from day one, and extensions to existing two-sided platforms where the supply-side or operator surfaces have hit a scaling wall. The first conversation is always about which side of that wall the product is on.
Stripe Connect or Adyen for Platforms?
Stripe Connect for early-stage marketplaces in the US and Europe with under $50M GMV per year. Adyen for Platforms for global marketplaces, multi-currency programs, or platforms where unit economics matter at scale. The decision drives ledger design, payouts, and operator tooling, so we make it deliberately in the first scoping sprint.
How do you handle trust and safety on a marketplace?
Three layers. Identity verification at onboarding through Onfido, Persona, or Sumsub. Behavioral and transactional monitoring at runtime through Sift, Unit21, or a custom rules engine. Operator surfaces for the trust-and-safety team with structured case management, reason codes, and audit logs. Skipping any one of these layers is how marketplaces lose to bad actors at scale.
How long does a marketplace MVP take to ship?
A focused supply + demand + payments MVP takes 12 to 16 weeks with a senior engineering pod. A production-grade two-sided platform with KYC, payouts, search, ranking, dispute handling, and operator tooling typically takes 6 to 9 months. We ship in two-week sprints with working demos so the team always knows where things stand.
