Buyer discovery & search
Search, filters, categories, maps and sort that get people to the right listing in seconds, not scrolls.
App UI/UX Design · AI-First · Results-Driven
A marketplace or on-demand app is really two apps in one. The demand side — buyers, riders, guests — needs to search, compare and book in a few taps. The supply side — sellers, drivers, hosts — needs to list, get discovered, accept requests and get paid. Marketplace app design is the UX and UI work that makes both journeys feel effortless and keeps them synchronized, because a great buyer experience is worthless if there is nothing to buy, and vice versa. Get either side wrong and the flywheel never spins.
The levers that separate a marketplace that converts are fast, forgiving search and filtering, listing pages that answer every question before the tap to book, trust signals like reviews and verification, and a checkout that feels safe with clear fees and payouts. On-demand apps add live timing — request, accept, dispatch and track states that update in real time. The common mistakes are burying supply behind bad search, hiding fees until the last step, and designing the buyer flow while forgetting the seller has to fill it.
We map both journeys before styling a screen, prototype the request-and-accept loop so the timing feels right, and design listing, search and checkout screens as reusable components engineers can build directly. Everything gets tested with real users on both sides so friction is found before launch, not after your first thousand sign-ups.

Two-way reviews, verification badges, reporting and dispute flows that keep both sides accountable.
Services
End-to-end UI/UX design for two-sided and on-demand apps — from mapping both journeys to a production-ready design system your developers can build straight from.
Interviews with both audiences, competitor teardowns and journey maps for demand and supply so design is built on evidence.
Low-fidelity screens and flows for buyer and seller in parallel, locking the structure and the sync points before any pixel is styled.
Clickable prototypes of search, listing, booking and the request-accept loop you can test with real users on both sides.
Pixel-perfect screens with your brand, accessible type and color, and every state — empty, loading, live, error — designed.
Reusable listing cards, search patterns, checkout and map components with tokens so both sides stay consistent and fast to build.
Find where buyers drop off or sellers stall, then ship prioritized fixes to lift bookings and listings.

FAQ
Most two-sided app design engagements run from about $10,000 for a focused MVP covering both journeys to $35,000+ for a full on-demand product with a complete design system, maps and live-tracking flows. Cost depends on how many screens each side needs, research depth and how much real-time complexity is involved. Use the estimator above for an indicative range — the figure is approximate, and we confirm a firm quote on a free scoping call.
It is the UX and UI design for apps that connect two groups — buyers and sellers, or customers and providers. It covers search, listings, provider onboarding, real-time matching or booking, checkout and reviews, designed so both sides convert and stay in sync. It differs from single-audience app design because you are shaping two connected journeys at once, not one.
A clickable prototype covering both sides of an MVP typically takes 3–4 weeks; a full on-demand product with a design system runs 6–10 weeks. We work in short sprints so you review real screens for both audiences early, and design can run just ahead of development.
We research and map both journeys in parallel from the start, and identify the exact points where they hand off — a booking request, an acceptance, a payout. Both sides get their own wireframes, prototypes and usability tests, so supply is never treated as a bolt-on to the buyer experience.
Yes. We run a UX audit of both sides of your live app, find where buyers abandon search or checkout and where sellers stall in onboarding, and deliver a prioritized redesign — from targeted flow fixes to a full visual and design-system refresh.
Yes. We are based in Houston, TX and design marketplace and on-demand apps for clients across the US and internationally. Over 20+ years and 700+ projects we have collaborated with fully remote and hybrid teams over Figma, video calls and shared prototypes.
Yes. We are based at 9800 Richmond Ave in Houston (Westchase / Energy Corridor) and work with Houston startups and companies in person, as well as clients nationwide and worldwide.
Yes. Design is one part of our end-to-end software development, so the same in-house team can take approved screens straight into mobile or web development — including the maps, payments and real-time features a marketplace needs — with nothing lost in handoff.
