Trust gap—new buyers and sellers hesitate without social proof

How we build

We architect marketplaces on Supabase with Stripe Connect for automated seller payouts, Algolia for semantic search and matching, real-time messaging for buyer-seller negotiation, and reputation systems that bootstrap trust. Supply and demand dashboards give you real-time liquidity signals.

Questions

How do seller payouts work?

Each seller connects their bank account via Stripe Connect. We aggregate their earnings daily, calculate take-rate commission automatically, and send net funds weekly. Zero manual payroll overhead.

How do you prevent fraud and bad actors?

Tiered trust: identity verification for sellers, buyer feedback loops with moderation, automatic holds on accounts with dispute spikes, and manual review before refunds. Bad actors get banned and can't re-register.

Can you build search and recommendation?

Yes. Algolia powers full-text and faceted search. We layer in your own matching algorithm—proximity, seller rating, price range. Personalization improves conversion by 20-30%.

What if supply and demand become unbalanced?

Real-time dashboards show you days-of-inventory, seller activation rates, and buyer acquisition. We help you run promotions, adjust commission tiers, and identify bottlenecks before liquidity crashes.
