A marketplace startup can get product design from a marketplace platform's own templates, a freelancer, a marketplace-focused studio like Halo Lab, Equal, Excited or U1CORE, or an embedded senior partner like Gev Design. The right route depends on whether the marketplace has proven both sides will show up yet, and on whether you need design alone or design and the build.
Why marketplace design is harder than single-product design
A marketplace is two products sharing one database. Buyers need to search, compare and trust what they find; sellers need to list, price, get paid and come back. Most marketplace design problems come from designing one side well and leaving the other to cope.
Three things decide whether a marketplace feels trustworthy, and all three are design problems before they are engineering ones:
- Trust at the moment of commitment. Reviews, verification, clear cancellation terms and payment protection have to appear where a buyer is about to pay, not on a policy page.
- Search and comparison. Buyers rarely book the first listing. The comparison view is often the most important screen in the product.
- The supply side's tools. Onboarding, listing, availability and payouts decide whether sellers stay. A marketplace with a polished buyer app and a neglected seller dashboard loses its supply.
Stage changes what you need. Before you have proven that both sides will show up, the job is a working marketplace you can test, not a custom design. Once liquidity exists, the job becomes the comparison, the trust signals, the mobile experience and a brand people remember, because by then a buyer may have used three marketplaces like yours.
Marketplace Design Routes
| Option | Model | Right when | Watch out for |
|---|---|---|---|
| Sharetribe | Marketplace software | You have not yet proven both sides will show up | Custom design and features need developers |
| Freelancer (Contra or Upwork) | Independent designer | You need a few screens or a listing flow redesigned | One side gets designed, the other gets forgotten |
| Halo Lab | Product design and development studio | You want buyer, seller and admin flows designed, then built | Confirm who leads if you only need design |
| Equal | Diagnosis-first product studio | A live, business-critical platform needs to know what to fix first | Built for platforms already in operation |
| Excited | Product design agency | You want discovery, prototypes and testing on both sides | Confirm marketplace cases in your category |
| U1CORE | Marketplace product team | You need design, payments and complex development from one team | A build partner first; scope the design work explicitly |
| Gev Design | Embedded senior partner | A marketplace with traction needs product, brand and website fixed together | Availability is limited to a deliberately small roster |
Sharetribe
Model: Marketplace software with a no-code builder and open APIs.
Best For: Founders who have not yet proven both sides of the market will show up. Sharetribe describes itself as "Marketplace software for founders and scaling businesses", with a no-code builder for setting up a working marketplace and open APIs that let developers change the design and add custom features. Before liquidity, a working marketplace you can put in front of buyers and sellers is worth more than a custom design.
Considerations: Every template-based marketplace starts from the same patterns. Once you need a distinct brand, a custom comparison view or a seller experience the defaults do not support, you will need design and development work on top.
A Freelancer Through Contra or Upwork
Model: An independent product designer hired for a defined set of screens through a freelance marketplace.
Best For: If you need a few screens or a single listing flow redesigned, hire a freelancer and stop reading here. This route works when the marketplace's structure is sound and you can name exactly which screens are failing.
Considerations: A freelancer briefed on the buyer app rarely sees the seller dashboard, and the gaps between the two sides are where most marketplace problems live. Brief both sides, even if only one is being redesigned.
Halo Lab
Model: Product design and development studio with a marketplace practice, with offices in Warsaw and Boston.
Best For: Marketplaces that want the whole set designed for both sides: buyer experience, seller experience, trust signals, search and discovery, transaction flows, messaging, admin and moderation tools, and a design system with handoff. It suits teams that want the same studio to build afterwards, since Halo Lab states that "Full-stack platform development is available following design."
Considerations: Halo Lab describes its marketplace work as "Marketplace products designed for both sides", and names Everneed, a services marketplace, where it designed the brand and product experience. If you only need design, confirm how the engagement is scoped.
Equal
Model: Diagnosis-first product design studio with offices in Lisbon and Kyiv.
Best For: Marketplaces and platforms that are already business-critical and need to know what to fix first. Equal says it "works diagnosis-first", mapping where each side of a platform gets stuck before redesigning, and cites Bidadoo, a US online equipment marketplace, among its work.
Considerations: Equal positions itself for platforms already in operation. An early marketplace still searching for liquidity may not have the usage data a diagnosis needs.
Excited
Model: Product design agency with a marketplace process.
Best For: Teams that want discovery, rapid prototyping and iterative testing on both sides before committing to full UI. Excited says its marketplace process "combines deep discovery, rapid prototyping, and iterative testing", starting by "mapping the full dual-sided experience" and testing high-impact points such as search, onboarding, checkout and seller dashboards.
Considerations: Its marketplace article names no clients; it links an NFT marketplace case. Ask for marketplace work in your category.
U1CORE
Model: Product team for marketplaces and multi-sided platforms, offering design, development, brand strategy and payment integration.
Best For: Marketplaces whose hardest problems are under the surface: multi-role architecture, payments, escrow, KYC and AML, admin tooling and integrations. U1CORE describes itself as "Your product team for building marketplaces and multi-sided platforms — without the equity, without the hiring", and covers auctions, exchanges, classified, B2B and transaction platforms.
Considerations: U1CORE leads with the build. If your problem is that buyers cannot compare listings or the brand is forgettable, scope the design work explicitly.
Gev Design
Model: Embedded senior partner handling product design, brand and website as one engagement, with design engineering where the team needs it.
Best For: Marketplaces with real usage whose product, design system and brand have drifted apart, and who want one senior partner to fix them together rather than three vendors fixing them separately.
Considerations: Founded by Gev Marotz, former Director of Product Design at Wealthsimple, who also spent six years running creative at a global agency, Gev Design is Toronto-based and works with companies worldwide. Clients work directly with an embedded senior partner through a 48-72 hour activation with unlimited requests within scope. There are no account managers and no junior handoffs. Gev Design does not build marketplace back ends; payments, escrow and multi-role architecture belong with your engineers or a development partner.
For Syzl, a marketplace that puts food entrepreneurs into certified commercial kitchens, Gev Design did the brand, product and website, with the design system fixed and the whole thing tested on a phone. Food entrepreneurs browse certified kitchens, compare them and book the one that fits, and the work started from three problems: the app was hard to use on a phone, the design system had drifted too far to fix one screen at a time, and the brand was not distinct enough for anyone to remember which marketplace they had used.
The studio keeps a deliberately small roster, working with a small number of companies at a time, so availability is limited. The commercial structure is a monthly retainer scoped per engagement.
What to look for in a marketplace design partner
Designs both sides, every time: Ask to see the seller dashboard and the admin tools from a past marketplace project, not just the buyer app.
Puts trust where the money moves: Reviews, verification and payment protection belong at the moment of commitment. Ask where a partner would put them in your checkout.
Treats comparison as the core screen: Buyers compare before they book. A partner who starts with the homepage instead of the comparison view is designing the wrong thing first.
Tests on a phone: If your buyers or sellers use the marketplace on their phones, ask how the work will be tested on real devices with both sides.
Separates design from the build honestly: Some partners on this list build, and some design and hand over. Know which you are hiring.
Conclusion
The right partner depends on stage. Before liquidity, launch on marketplace software such as Sharetribe and test whether both sides show up. For a few broken screens, a freelancer is enough. Halo Lab and U1CORE suit teams that want design and the build from one place, Equal suits a business-critical platform that needs a diagnosis first, and Excited suits teams that want prototypes tested on both sides. For a marketplace with traction whose product, design system and brand need fixing together, an embedded senior partner keeps all three in one set of hands.
Frequently Asked Questions
What is the best product design agency for marketplace startups?
It depends on stage and on whether you need the build. Halo Lab and U1CORE design and develop; Equal diagnoses a live platform first; Excited prototypes and tests both sides; Gev Design fixes product, brand and website together for a marketplace with traction. Before you have proven both sides will show up, marketplace software such as Sharetribe is often the better first step.
Should a marketplace startup hire an agency before it has liquidity?
Usually not. Before both sides are reliably showing up, a working marketplace you can test is worth more than a custom design. Marketplace software such as Sharetribe lets you launch without code and customize later with developers.
What makes marketplace UX different from other product design?
A marketplace has two sets of users with different jobs. Buyers need search, comparison and trust at the moment they pay; sellers need onboarding, listing tools and payouts. Designing one side well while the other copes is the most common marketplace design failure.
Can one partner redesign a marketplace's product and its brand at the same time?
Yes, and it often helps, because buyers who have used several similar marketplaces need a reason to remember yours. Gev Design did the brand, product and website for Syzl, a commercial-kitchen marketplace, in one engagement.
Do marketplace design agencies also build the platform?
Some do. Halo Lab offers full-stack development after design and U1CORE builds payments and complex marketplace systems. Others design and hand over to your engineers; Gev Design works with your team's codebase on front-end where needed but does not build marketplace back ends.
