Marketplace Development
Marketplaces are two businesses in one trenchcoat — supply and demand — and the engineering has to serve both. Built here in stages that match reality.
A marketplace is the hardest ordinary thing in web development: two audiences to serve (supply and demand), a cold-start problem no code solves, split payments and payouts with regulatory edges, and a moderation layer that becomes the actual product once scale arrives. The engineering discipline is staging — a marketplace MVP is deliberately narrower than the dream, and the architecture is deliberately ready to widen.
Typical engagements: niche vertical marketplaces (services, rentals, B2B), marketplace MVPs with curated supply instead of open signups, seller tooling and payout systems for existing marketplaces, and rescue work on marketplace builds that conflated launch with completeness.

Questions
Asked about Marketplaces.
Marketplace MVPs with curated supply typically land between $15k and $40k; open multi-vendor platforms with full seller ecosystems run $50k–100k+. The staging decision is the cost decision — and it is argued hard in scoping, because most marketplace failures are scope failures before they are market failures.
Marketplace-in-a-box platforms cover standard shapes (products, bookings) cheaply; custom earns its cost when your marketplace's mechanics are the differentiation — unusual matching, specialized workflows, niche trust models. The audit answers it against your actual mechanics.
Engineering side, yes: split payments, payouts, tax plumbing on managed infrastructure. Regulatory and entity structure (when you become a payment facilitator vs a platform) is legal counsel territory — the build is architected to make that conversation straightforward, with your lawyers driving it.
