Outsource Mobile App Development
Outsource mobile app development to a senior team without the offshore lottery. We're a Tallinn-based agency that delivers iOS and Android apps end to end — clear scope, EU timezone overlap, and code you fully own. Built for startups and SMBs that need to ship without hiring an in-house team.

Our Approach
How We Run an Outsourced Build
Outsourcing fails on communication and ownership, not coding. We structure every engagement so you stay in control and never lose visibility.
One accountable team
You get a dedicated team with a single point of contact, not a rotating cast of contractors. The people who scope it are the people who build it.
Transparent by default
Shared backlog, weekly demos, and access to the codebase throughout. You always see real progress, not a status email written to reassure you.
Timezone that overlaps yours
Based in Estonia, we share working hours with Europe and have meaningful overlap with the US East Coast. Questions get answered the same day.
Fixed-scope or dedicated-team, your call
Fixed price for a well-defined build, or a dedicated team you direct month to month for evolving products. We recommend the model that fits your stage.

Why Prosperity
Why Outsource to Us
We've delivered 40+ products for clients across Europe and the US, including a major hearing-care group and European utilities. Outsourcing to us feels like an extension of your team.
Senior-only delivery
No junior bench billed at senior rates. The engineers on your project have shipped production apps before and don't learn on your budget.
EU quality, competitive cost
Estonian rates are well below US and UK agencies but you keep EU work standards, GDPR fluency, and easy communication. A genuine middle ground.
Honest about the trade-offs
Outsourcing isn't free of friction — you give up some direct control and need to invest in clear briefs. We'll tell you when hiring in-house would serve you better.
Built for clean exits
We document as we build and keep everything in your accounts. Whether you stay or leave, you're never trapped by our involvement.
FAQ
Frequently Asked Questions
Usually, yes — for one project or a fixed period. Hiring an in-house iOS and Android team means recruitment, salaries, benefits, and management overhead before a line of code ships. Outsourcing converts that into a predictable project cost with no long-term commitment. In-house wins once you need a permanent, evolving product team.
