For Marketplaces founders
Engineering for
Marketplace Founders
Marketplaces are full-stack products with two distinct user flows, payment routing, dispute resolution, search, and trust signals. That's why most marketplace MVPs ship at 3 months instead of 4 weeks. The cost isn't engineering hours — it's coordination overhead between specialists.
Marketplaces are network-effect businesses. Slow time-to-supply means slow time-to-demand. The supply side has to be live and stocked before demand-side acquisition starts paying off.
Stack we use
Compliance
Tax / 1099 reporting if your marketplace has US sellers — we integrate with Stripe Tax or Avalara. Sales tax nexus is complex and we won't pretend it's not; you need a tax advisor too.

Why marketplaces builds are different
Same engagement model.
Industry-specific defaults.
We don't pretend a generic SaaS stack ships marketplaces at v1. The pain points below are what most builds in your industry get wrong on the first try — we wire them correctly from commit one.
The pain points
What breaks at v1 in marketplaces
Each of these is something we've watched founders get wrong on the first build. We ship the correct version on day one.
01
Two-sided onboarding without two-sided code duplication
Most marketplace MVPs ship two parallel auth/profile/dashboard codebases for buyers and sellers. They diverge fast. We architect a shared base with role-specific surfaces.
02
Stripe Connect done right
Account types, payment routing, KYC requirements, payouts, dispute handling, application fees. Connect is its own product — skipping a feature here means rebuilding it once a dispute happens.
03
Search and matching that actually works
Postgres full-text gets you to 100 listings. Past that you need proper search infrastructure (Typesense, Algolia, or a dedicated Elasticsearch). We choose based on traffic profile, not defaults.
04
Trust signals that match the category
Reviews, verified badges, dispute history. Each category needs a different mix. We don't ship 'reviews' as a generic feature; we ship the trust signal the market needs.
What we ship
Concretely,
by handoff.
The work you'd hand a salaried marketplaces engineer — done end to end on a flat-price engagement.
- Shared auth/profile base with buyer + seller role surfaces
- Stripe Connect with proper KYC, payouts, application fees, disputes
- Search (Postgres FTS / Typesense / Algolia, picked based on scale)
- Reviews + verified badges + dispute resolution
- Admin to actually run the marketplace (suspend accounts, refund manually, etc.)
