Marketplace development is one of the hardest things to get right. You're effectively shipping two products at once (one for buyers, one for sellers), running money between strangers, and racing for liquidity before competitors get there first. White-label marketplace platforms (Sharetribe, Yo!Kart, CS-Cart Multi-Vendor) get you live in weeks but cap you on customisation and charge perpetual fees as you scale.
Custom-coded marketplaces flip both problems: built around your exact category and trust model, no per-transaction or per-vendor platform tax, and engineered to scale from 10 vendors to 10,000 without a rewrite. We've built marketplace MVPs in 8–14 weeks on the same React + TypeScript + Supabase + Stripe Connect stack as our SaaS work.
Pairs naturally with our web app capability — most marketplaces evolve into full operations platforms over time.
