Taking over a Sharetribe marketplace someone else built
Your marketplace is live, but the developer who built it has disappeared, the code is hard to follow, or every change breaks something else. Often it started as the cheaper option. We have taken over many Sharetribe projects in this state.
- Code audit. You send us access. We look at the code, the architecture, what works and what doesn't, and you get a written report of what to keep and what to fix.
- Stabilize. We fix what breaks first, so a change to one part stops breaking another.
- Then new features. Once the base holds, we build what's next and use our ready-made extensions where they fit.
What we usually find when we take over
- Servers nobody has updated in years.
- Deadlines that kept slipping, and a developer who got harder to reach.
- Often no maintenance plan, because nobody offered one.
Planning a new marketplace
Start with a discovery call. We tell you whether Sharetribe fits, then scope and build it.
How a project worksOn an older Sharetribe version
Moving from Sharetribe Go or an older template to the current platform.
Most of our clients stay with us for years.
We migrated our Sharetribe from another service provider to Gunars and IT House, and have been extremely happy with their work. Everything from communication to staging, development and service options has been premium quality and always on time.
Why work with us on your Sharetribe marketplace
Product experience since 2003, beyond Sharetribe
Since 2003 we've built enterprise platforms, SaaS products, e-commerce systems, and complex web applications. Every marketplace is a business, so we bring that product experience to your pricing model, onboarding flow, and growth strategy.
A team that's worked with Sharetribe directly
We've worked with Sharetribe's team since their early platform days, back when it was called Sharetribe Go. We understand how the platform works under the hood, so we debug faster and design the architecture with fewer surprises.
Ready-made extensions that save weeks
Shopping carts, wishlists, checkout add-ons, customer verification, alternative payment gateways, and more. We reuse proven components where they fit instead of rebuilding the same feature from scratch.
Senior attention on every project
A dedicated project manager who knows your marketplace, backed by senior developers with 7+ years of experience. On complex problems, our founder joins the team to help find the best solution. You work with the same senior people from kickoff to launch.
The team has worked with many ST projects already so they can think creatively with you and solve problems in a cost efficient and effective way. … They kept the schedule, were professional and all features work as expected. Most importantly the developments don't block you managing everything from the console so you remain independent after.

How a typical Sharetribe project works
01
Discovery call
You tell us about your marketplace idea. We tell you whether Sharetribe is the right fit, or whether you need something else.
02
Scope & design (1 week)
We define features, choose extensions from our library, and design your marketplace to match your brand.
03
Build (2 to 6 weeks)
Custom transaction flows, integrations, design implementation. You see working progress throughout.
04
Launch & iterate
Your marketplace goes live. We help you onboard first users and iterate based on real feedback.
The first call is free. Bring your questions, leave with a clear next step.
Book a free callWe think about your business first
We've been founders too, so we ask about your pricing, onboarding and growth before we talk about features.
We challenge your feature list before building it
Is this the right marketplace model? Will your users actually pay for this? Should you launch leaner and test demand first? We know which questions to ask because we asked them about our own marketplace first.
Broader experience makes Sharetribe projects sharper
We migrated Betty Blocks from Ruby on Rails to Elixir for enterprise-scale performance. We've built legal tools for Karnov Group. That depth informs decisions on your marketplace, from pricing models to scaling architecture.
If you outgrow Sharetribe, we're still here
Most marketplaces won't need this. Sharetribe can take you very far. But if the day comes when you need custom infrastructure, we build that too, with Ruby on Rails, Next.js, Node.js, Elixir. We help you transition without starting over. You don't need to find a new team.
Custom marketplace developmentOur rule of thumb on platform vs. custom
If Sharetribe covers 80% of what you need, stay with Sharetribe and customize the rest. If it covers less than half, a custom build might fit better. We'll tell you which side of that line you're on.
Custom marketplace developmentOur first-sprint guarantee
If after the first sprint you don't feel like we're the right partner, we stop and don't invoice for that sprint.
If we're the wrong fit, we'll say so on the first call and point you to a better option.
Book a free callFrequently asked
How long does it take to build a Sharetribe marketplace?
You can launch a basic marketplace in as little as 1 week. Most customized projects with design and integrations take 2 to 6 weeks.
What happens when I outgrow Sharetribe?
Most marketplaces never need to leave Sharetribe. If you do, we handle the transition. See custom marketplace development →
Can you add AI features to my Sharetribe marketplace?
Yes, AI-powered search, content generation, and recommendations using OpenAI, Anthropic, or other models.
Do you work with Sharetribe directly?
We've worked with Sharetribe's team since their early platform days. Sharetribe CEO Juho Makkonen has publicly recommended our work.
Can you take over an existing Sharetribe marketplace?
Yes. We review what's already built, assess what's salvageable, and take it from there. We have also migrated an existing marketplace from Sharetribe Go to the new Sharetribe infrastructure, moving all users and listings without data loss.
Who owns the code?
On a Sharetribe build, the code we write for your marketplace is yours. Sharetribe itself stays a hosted platform you subscribe to. If we build a fully custom platform, you own the whole codebase.
Do you work with Sharetribe's no-code setup, the developer platform, or both?
Both. Sharetribe's no-code tools cover simple changes and its APIs cover complex features. We have worked with Sharetribe's own team since their early platform days.
What affects the cost of a Sharetribe project?
It depends on what you need. The main factors are the features and extensions you choose, how far the design moves from the default template, the integrations you add, and, for an existing marketplace, the state of the code we take over. We go through the specifics on the discovery call, then define features, extensions, and design in the scope step, before we give you an estimate.
