Two apps wearing one logo
One side opens it forty times a day to earn a living. The other opens it once a month to get something done. Building a single experience for both is how marketplaces lose their supply.
What's different here
Marketplace apps are almost always designed demand-first, because that is who the funding deck is about. The result is a beautiful buyer experience and a supply-side tool that a professional has to use all day and quietly hates. Since supply is the harder side to acquire and the more expensive to replace in nearly every marketplace we have worked on, that priority is backwards — the side with the higher switching cost should get the better software.
Marketplaces & Platforms clients
What app development looks like for marketplaces.
These are the plays that wouldn't appear on a generic app development page — they only make sense in marketplaces & platforms.
Treat the supply app as professional software
Someone using your app to run their working day needs density, keyboard-and-glance efficiency, offline tolerance and speed over polish. The design conventions that make a consumer app feel pleasant — generous whitespace, one action per screen, animated transitions — actively slow down a person doing this forty times before lunch.
Instrument the two sides on different metrics
Demand-side health is conversion and repeat rate. Supply-side health is time-to-first-earning, jobs accepted per active provider, and the churn of providers in their first month. Blending both into one engagement dashboard hides the metric that actually predicts whether the marketplace survives.
Design for the empty state, because early on that is the product
A liquidity gap is the normal condition of a young marketplace, and it shows up in the app as an empty list. What that screen says — expected wait, nearby alternatives, an honest estimate — does more for retention in the first year than any feature, and it is almost always an afterthought.
Notifications are the marketplace, not a channel
On the supply side a missed notification is lost income, so delivery reliability is a product requirement rather than a growth tactic. We treat the notification path as critical infrastructure — delivery confirmation, fallback channels, and a review of what genuinely warrants interrupting someone at work.
What holds marketplaces back
The cold-start problem
Buyers leave because supply is thin; suppliers leave because there's no demand. Both sides churn and neither reaches critical mass.
You're spread across too many categories
Marketing eleven categories at once means none reaches liquidity. Concentration feels risky and is almost always the right call.
You're measuring GMV, not match rate
GMV can grow while the core experience gets worse. Match rate and time-to-first-match are the health metrics that actually predict retention.
Supply-side churn is invisible
Suppliers who receive no requests quietly stop responding. By the time it shows in your numbers, the damage is done.
The full scope.
Everything in a app development engagement, applied to marketplaces & platforms.
Product discovery & scoping
Jobs-to-be-done research, user flows, and a ruthlessly prioritized MVP scope with everything else parked in a v2 backlog.
UX & UI design
Full interface design across every state — loading, empty, error, success — plus a component library in Figma.
Cross-platform mobile build
React Native for iOS and Android from one codebase, with native modules where performance genuinely requires them.
Web application build
Next.js with server components, type-safe APIs, and a database layer designed for your actual access patterns.
Backend & infrastructure
Auth, database, storage, background jobs, and CI/CD — deployed on infrastructure that scales without a rewrite.
Analytics & observability
Product analytics, crash reporting, performance monitoring, and error tracking wired in before launch, not after.
App Store submission
Store listings, screenshots, review guideline compliance, and submission managed end to end.
Post-launch iteration
An included sprint of improvements based on the first month of real user behavior.
How this runs.
Discovery
Weeks 1–2User research, competitive review, technical feasibility, and MVP scope definition with explicit cut lines.
Design
Weeks 2–4User flows, wireframes, and full UI design for every screen and state, prototyped and tested with real users.
Build
Weeks 4–10Two-week sprints with a working build in your hands at the end of each one. No black-box development.
QA & launch
Weeks 10–12Device testing, performance profiling, beta distribution via TestFlight, then store submission.
Iterate
Month 4+Analytics review, user feedback synthesis, and a prioritized roadmap for the next release.

Marketplaces & Platforms questions, answered straight.
You can, and plenty do, but be clear about what it costs. A shared app forces compromises that land hardest on the side you are least able to lose, and the migration later means asking your providers to install something new at the exact moment you need them least disrupted. If budget only covers one build, our advice is usually to build the supply app properly and serve demand with a good mobile site — that is the opposite of what most founders expect to hear.
