Marketplace · 720-hour cycle
kaedax builds two-sided marketplaces — services, goods, B2B procurement — in a fixed 30-day (720-hour) cycle. Marketplace engineering is liquidity engineering: supply onboarding that doesn't leak, matching that converts, payments with escrow and splits, and the trust systems that keep both sides from going around you.

[ §01 ] the problems we're hired for
Chicken-and-egg is strategy, but supply onboarding friction, empty-state design, and single-player utility are engineering. We build the surfaces that make a thin marketplace useful at day one, so your supply acquisition spend isn't wasted on a leaky funnel.
Escrow, split payouts, refunds across two parties, KYC on sellers, marketplace-of-record liability — getting this wrong is existential. We build on Stripe Connect or equivalent rails with reconciliation jobs from day one.
The moment both sides trust each other, they're motivated to go around you. The defense is engineered: in-platform value (escrow, insurance, dispute resolution, scheduling) that makes leaving costlier than your fee.
Reviews that resist manipulation, verification flows, dispute resolution with evidence trails — the unsexy systems that decide whether transaction #10,000 happens. They're in our first spec, not your post-launch backlog.
[ §02 ] what ships
The shapes of marketplaces work that fit a 720-hour cycle. Every build ships with runbooks, monitoring, and 30–60 days of post-launch on-call.
Buyer and seller surfaces, onboarding funnels for both sides, empty-state-aware UX.
Search, filters, ranking, and recommendation surfaces tuned for conversion on thin supply.
Escrow, split payouts, refunds, seller KYC — on Stripe Connect rails with reconciliation jobs.
Reviews, verification, dispute workflows with evidence trails — the moat against disintermediation.
[ §03 ] proof
Escrow, KYC, payouts — the scary parts were done by week two. We spent the rest of the cycle on matching, which is the part that actually wins the market.
[ §04 ] questions
Market quotes for two-sided marketplace MVPs run $50,000–$250,000 over 3–6 months, with payments and trust systems driving the spread. kaedax prices per fixed 720-hour cycle, shared on the scope call. One cycle ships both sides plus payments.
Stripe Connect or equivalent rails: escrow, split payouts, two-party refunds, seller KYC, and reconciliation jobs from day one. Marketplace payments are a different discipline from checkout, and we treat them that way.
Yes — empty-state design, single-player utility, and low-friction supply onboarding are engineering choices we make deliberately. Our ATRIUM engagement shipped a marketplace built for thin-liquidity day one.
Disintermediation defense is engineered: escrow, dispute resolution, scheduling, and insurance live in-platform so leaving costs more than your take rate. We design those hooks into the first transaction flow.
One cycle ships a focused marketplace: both sides, matching, payments, and core trust systems. Deep verticalized features (logistics, insurance, financing) typically land in a second cycle — we map this on the scope call.
