Building a marketplace is harder than building a store. You are serving two groups of users at once, moving money between them, and asking strangers to trust each other. That is why the best marketplace app development firms tend to look different from general software shops: they talk about vendor onboarding, split payouts, search relevance, reviews and dispute handling before they talk about frameworks.
This list covers ten firms that build two-sided and multi-vendor marketplaces for web and mobile, and that publish marketplace case studies on their own sites. Some build fully custom platforms, some work on top of Sharetribe or the open-source Medusa stack, and one builds on low-code tools for founders who need to validate demand fast. If your project is closer to a single-seller store, our guide to ecommerce website development companies is a better starting point.
Every company here was checked against its own website: service pages, named marketplace projects and the facts each firm publishes about itself. Where a figure is the firm’s own claim, we say so.

Best Marketplace App Development Firms In 2026
The firms below are ordered by how central marketplace work is to their business, with dedicated specialists first.
1. CobbleWeb — London Studio Building Custom Marketplaces Since 2012
CobbleWeb is one of the few firms on this list that does almost nothing but marketplaces. The London-based company was founded in 2012 by Ramdane Mir (CEO) and Paul Payen de La Garanderie (CTO), and it lists offices in London, Paris and Dubai. Its pitch is that a marketplace succeeds on platform architecture and user journeys, not just code, so its engagements cover UX research, product design, build and post-launch analytics.
The firm treats payments as a core part of the product rather than a plugin. According to its site, it configures payment service providers around each client’s business model, which matters when you need escrow, delayed payouts or commission logic that a standard checkout cannot handle. Work runs in two-week Lean Agile iterations.
The published case studies are specific. CobbleWeb says it rebuilt Affordable Art Fair’s product marketplace to replace an earlier Magento build, reporting a 50% rise in turnover and 65% higher customer spend. It also lists FanPass, a ticket resale marketplace, Nestify, an Airbnb property management platform with a cleaner-facing mobile app that has expanded to seven countries, and Soshop, a cashback rewards platform with more than 25,000 merchants. These results are the firm’s own figures.
CobbleWeb suits founders and established brands who want a partner that has already solved the common marketplace problems, especially in Europe, and who value product strategy alongside engineering.
2. Codica — Custom Marketplace Builder With 16 Published Marketplace Case Studies
Codica is a software company registered in Tallinn, Estonia, with a team of more than 60 people and nine years in the market, according to its site. Marketplace development is one of its headline services, and its case study library is dominated by marketplace projects, mostly for clients in Australia, the US and Europe.
The range is wide. Codica lists Trade A Boat and TradeRVs, Australian marketplaces for boats and recreational vehicles, a multi-vendor vehicle platform in Africa that runs more than 90 country-localized marketplaces on one codebase, and Nextor, a UAE multi-vendor parts marketplace with buyer, vendor and admin portals, bulk inventory import, multi-carrier shipping and Elasticsearch-driven search. It also built PlanMyKids, a US service marketplace where parents book kids’ activities, and Go Golfer, a peer-to-peer golf equipment marketplace that uses the OpenAI API to moderate buyer and seller chat.
Codica tends to report outcomes in traffic and sales terms. The agency says the iExpedition travel marketplace generated $2 million in sales in its first year, and that the African vehicle platform saw 430% traffic growth over two years after SEO work. It also says its startup clients have raised more than $56 million combined.
Codica is a strong fit for vertical product marketplaces with large catalogs, complex search and parts data, and for founders who care about organic search from day one.
3. Journeyhorizon — Premium Sharetribe Partner Focused On Two-Sided Marketplaces
Journeyhorizon was founded in 2018 by Matthew Ryan and Tri Nguyen and pairs Australian product and business leadership with an engineering team in Vietnam. The company describes itself as a marketplace development and marketing partner, and its site lists it as a Premium Sharetribe Partner. It works across rental, services, product, B2B and classifieds marketplace models.
Sharetribe’s own co-founder and CEO, Juho Makkonen, is quoted on Journeyhorizon’s site calling it one of Sharetribe’s first development partners and saying it has helped clients launch more than 100 marketplaces. Beyond custom Sharetribe builds, the firm sells plugins and mobile app templates, which can shorten the path from a web marketplace to native apps.
Its featured case study is GearSource, a global B2B marketplace for professional audio, video, lighting and staging equipment. Journeyhorizon reports that organic traffic rose 31% and indexed pages grew from about 4,000 to 19,000. Sugarlift’s founder is also quoted praising the firm’s marketplace work. The company says it has nearly 60 specialists and clients in more than 20 countries.
Journeyhorizon suits founders who have chosen Sharetribe, or are open to it, and want a team that can extend the platform with custom features and help with marketplace marketing after launch.
4. Roobykon Software — Sharetribe Specialist With A Large Rental And Sharing Portfolio
Roobykon Software calls itself an online marketplace development company, and its site backs that up with a dedicated Sharetribe development practice and a long list of live marketplace projects. The company lists a Tallinn, Estonia address and says it has more than ten years of experience building and scaling Sharetribe marketplaces, with clients in over 50 countries.
Payments are a visible part of the offer. Roobykon integrates Stripe Connect and Stripe Tax and displays a Stripe Verified Partner badge. Sharetribe’s co-founder and CEO is quoted on its site saying Sharetribe recommends Roobykon to its customers, a useful signal when you are choosing someone to extend a hosted platform.
The portfolio leans toward rental and sharing models. Named projects include Drive lah, a peer-to-peer car sharing platform, Upisle for yacht rental, HotPatch for flexible workspace rental, HomeHak, a tenant-first rental marketplace, Rosella Street, a circular-economy sharing platform, and Aircraft For Sale, a marketplace for aircraft buyers and sellers. Roobykon also lists learning, wellness and expert-services marketplaces such as AllCourse and Book Holistic.
Roobykon is a good fit for booking-based and rental marketplaces where availability calendars, deposits and Stripe Connect payouts are the core of the product.
5. Rigby — Creator Of The Open-Source Mercur Marketplace Platform On Medusa
Rigby is a Polish team of more than 50 people with offices in Wrocław, Warsaw and Rzeszów. It builds commerce platforms on Medusa, the open-source headless commerce engine, and it created Mercur, an open-source marketplace platform built on Medusa’s core. That gives clients a multi-vendor foundation they own outright, without per-transaction platform fees.
The firm offers multi-vendor, B2B, B2C and MVP marketplace development. Because Mercur handles the vendor, order and commission layers, Rigby’s projects tend to focus on the parts that differ from client to client: integrations, custom checkout logic and unusual product types.
Its published work reflects that. Montelink is a service marketplace on Mercur that supports seven business areas and three product types in one checkout, with AI-based translations. Rapid Data is a multi-tenant B2B2C marketplace for the funeral industry, which Rigby says now runs more than 1,000 storefronts and reached a production-ready MVP in about three months. For Septeo CNEE, it built a Medusa marketplace connected to Microsoft Dynamics Sales to remove manual order entry into the CRM.
Rigby suits companies that want an open-source, self-hosted marketplace they can extend over time, particularly B2B operators with ERP or CRM integration needs.
6. Chop Dawg — Philadelphia App Studio Shipping Two-Sided Marketplace Apps Since 2009
Chop Dawg is a Philadelphia app development studio that says it has been shipping mobile and web apps since 2009, with more than 500 launches across iOS, Android and the web. It is a generalist studio, but it publishes several marketplace builds, and they show the kind of mobile-first, two-sided products the team is comfortable delivering.
The most detailed is Park King, a parking marketplace where owners list spaces and drivers book them. Chop Dawg built React Native apps for iPhone and Android that launched in both stores at the same time, plus a staff web dashboard for inventory, policy and insights. Stripe handles Apple Pay, Google Pay and card payments, splits fees and releases funds when a booking ends. The build includes a live availability map with EV-only filters, transaction-safe locking to prevent double bookings, photo verification, in-app chat, tiered approval for listings and a dispute console for refunds, warnings and bans.
The studio also lists BedMatch Pro, a senior care placement marketplace, and QuickPro, a home help marketplace. It does not publish traction numbers for these projects, so ask for references if outcomes matter to your decision.
Chop Dawg is a fit for US founders whose marketplace lives mainly on the phone and who want a single team to handle design, both native apps and the admin back office.
7. LowCode Agency — FlutterFlow And Bubble Partner With Published Marketplace Pricing
LowCode Agency is a Miami-based firm founded in 2019 by Jesus Vargas. It builds on low-code platforms and describes itself as an official FlutterFlow agency partner and a Bubble Silver Tier certified agency. The company says it has more than 40 people and has built over 450 apps.
Its marketplace service covers two-sided and multi-sided platforms, built mostly with FlutterFlow for cross-platform iOS and Android apps, Supabase for data and Stripe Connect for money movement. The agency lists escrow, split payments, platform fees, seller payouts and refunds as standard payment features, with escrow recommended for high-value transactions.
What sets it apart is transparency on cost. LowCode Agency publishes typical ranges on its site: $25,000 to $50,000 for an MVP over 8 to 12 weeks, $50,000 to $100,000 for mid-complexity builds over 12 to 18 weeks, and $100,000 to $200,000 or more for full-featured platforms over 18 to 28 weeks. Its marketplace page features work for Sotheby’s International Realty, where the agency reports 75% faster listing management after centralizing data.
LowCode Agency suits founders who need to test liquidity on a real product within one quarter, and who accept the tradeoffs of a low-code stack in exchange for speed and a predictable budget.
8. Clockwise Software — Builder Of The Workerbee B2B Consulting Marketplace With Stripe Escrow
Clockwise Software is a Ukrainian product development company headquartered in Dnipro that says it has been building products since 2014. Online marketplaces are one of its listed areas of expertise, framed around platforms that connect vendors and customers, alongside SaaS and web application work.
Its flagship marketplace case is Workerbee, a US multi-vendor marketplace where businesses find software modernization and integration specialists. The platform serves individual consultants, consulting agencies, software vendors and buyers. Clockwise built a matching score that ranks providers against customer requirements, escrow payments through Stripe, a net-30 option with purchase orders and enterprise invoicing in the admin panel, and Twilio-based communication. It also added a lead manager role so a human capital management partner can review and assign incoming requests to agencies.
The case study lists the team (a project manager, business analyst, designer, two frontend and two backend developers and a QA engineer) and notes the engagement has run since December 2021, with iOS and Android apps planned. Clockwise says the marketplace is live and that the partnership channel grew Workerbee’s customer base.
Clockwise is a good match for B2B service marketplaces that need invoicing, approval workflows and matching logic that consumer-focused templates do not cover.
9. Django Stars — Python Team Behind Proptech And Mortgage Marketplaces Since 2008
Django Stars has been building software with Python and Django since 2008, according to its site, and now has more than 100 team members. The company keeps an office in Kyiv and lists a US business address in Wilmington, Delaware. Its client base is spread across Europe, the US, Switzerland, the UK and the Middle East.
Its marketplace work is concentrated in property and finance, where pricing models, document checks and data pipelines are as important as the listing pages. Django Stars says it built Scoperty, a German proptech marketplace, from scratch, including mapping features and automated price estimates for real estate agents. It engineered Lendage, an end-to-end digital mortgage marketplace that automates financial data checks and scoring, and it built WeCre8, a bilingual ecommerce marketplace with a warehouse management system that launched with more than 7,000 products.
The firm also lists MoneyPark, the Swiss mortgage and advisory platform, among its named clients, which gives a sense of the regulated, data-heavy environments it is used to.
Django Stars suits marketplaces where the hard part is the back end: scoring, valuations, compliance checks or integrations with financial data sources. It is less of a fit for a quick consumer MVP.
10. Apiko — Marketplace Practice Covering B2B, B2C And Peer-To-Peer Models
Apiko is a software development company that lists a Tallinn, Estonia address and reports more than 85 completed projects. Marketplace development is a named area of expertise on its site, with separate service pages for B2B, B2C and peer-to-peer marketplaces, plus MVP, SaaS and mobile app work.
Its marketplace case studies are aimed at services and finance. Good Life Sorted is a UK marketplace that connects older adults with vetted helpers for household chores, cooking, shopping and companionship, a model where vetting and trust are central to the product. Apiko also built the mobile app for Multi, which it describes as the top financial services marketplace in Ukraine, supporting conversion across more than 150 currencies alongside loan management, transport insurance and cashback offers.
Apiko also points to long client relationships outside marketplaces. It says it has worked with Hive, the US project management tool, for more than ten years, during which Hive raised $28 million. That kind of tenure is relevant for marketplaces, which usually need a steady team well after launch.
Apiko fits founders building care, services or peer-to-peer marketplaces who want a partner that can take a product from MVP through several years of iteration.
How To Choose A Marketplace Development Partner
Should You Build Custom Or Start On A Platform Like Sharetribe?
Hosted marketplace software such as Sharetribe gives you listings, search, transactions and Stripe Connect payouts out of the box, so a capable team can launch in weeks. Open-source options such as Medusa with Mercur give you similar building blocks you host and own. A fully custom build makes sense when your transaction model is unusual: multi-party bookings, negotiated pricing, regulated payments or deep ERP integration.
Ask each firm which route it would take for your model and why. A good partner will tell you when you do not need custom code yet. Be wary of anyone who recommends the same stack for every project.
How Will Payments And Payouts Work?
Money movement is where marketplace projects most often stall. Ask how the firm handles seller onboarding and identity checks, commission and fee logic, delayed or escrowed payouts, refunds, chargebacks and taxes. Stripe Connect is the most common choice, but ask which account type the firm recommends and how it handles sellers in countries Stripe does not fully support.
Request a walkthrough of a live payout flow from a previous project. If the team cannot explain who holds funds at each step, keep looking.
Has The Firm Built Your Type Of Marketplace Before?
Rental marketplaces need availability calendars and deposits. Product marketplaces need catalog management, shipping and returns. Service marketplaces need matching, scheduling and quoting. B2B platforms need invoicing and approval chains. These are different products, and experienced marketplace developers will have case studies close to yours. Ask to speak with a past client whose model matches your own.
What Is Their Approach To Trust And Safety?
Reviews, identity verification, listing moderation, messaging rules and dispute tools are what make strangers willing to transact. Ask how the firm handles fake listings, off-platform leakage, review manipulation and refund disputes, and what admin tools your operations team will get on day one. Admin tooling is often underestimated in proposals, and it is what your team will use every day.
How Do They Plan For Search And Liquidity?
A marketplace with good supply that buyers cannot find will still fail. Ask how the firm approaches search relevance, filters, sorting and SEO for listing pages. Firms that report traffic results on their case studies, as several on this list do, have usually thought about discoverability as part of the build.
Also ask how they would help you seed one side of the market, for example with bulk vendor import tools or concierge onboarding flows.
What Will It Cost To Launch And Keep Running?
Get the build estimate and the run cost separately: hosting, platform subscriptions, payment fees and the monthly retainer for fixes and new features. Low-code and hosted-platform builds are cheaper to launch but can carry ongoing platform fees, while custom builds cost more upfront but leave you owning the code. Ask for a phased plan that gets a usable MVP in front of real buyers and sellers first, then budget for at least a year of iteration after launch.
