Mobile-first
Most investment decisions happen on phones. We prioritized the mobile experience from day one and treated desktop as secondary.
CASE STUDYFINTECH · REAL ESTATE
We built RentInvesto from scratch in 8 months — the entire platform, from mobile app to admin panel. It's the first app in Poland that lets you invest in real estate as easily as opening a bank deposit. We joined in April 2024 as their technology partner.

RentInvesto had deep real estate expertise and a clear vision: make property investment accessible to everyone in Poland. What they didn't have was a working platform.
Investment platforms in Europe must meet strict regulations around identity verification, document signing, and financial transactions. Speed couldn't come at the cost of compliance. This wasn't just an app; it was financial infrastructure.
Mobile apps (iOS and Android), a web version, and an admin panel for the RentInvesto team.
Users verify their identity through Veriff, sign investment agreements electronically via Signius, and can start investing within minutes.
Investors deposit funds through Stripe. Monthly rental income is automatically distributed through zen.com.
A voice-enabled assistant (built with LiveKit and OpenAI) that answers questions about properties and investments in natural conversation.
The RentInvesto team can add properties, configure investment parameters, track user activity, and manage the platform without developer help.
We started from scratch — no legacy code, no inherited problems. This gave us freedom to make the right architectural decisions from day one.
Compliance wasn't an afterthought. We built identity verification, electronic signatures, and regulatory checks into the core flow. When regulations changed mid-project (which they did), our modular approach meant we could adapt without major rewrites.
We worked in close collaboration with the RentInvesto team, validating each phase before moving to the next. This prevented scope creep and kept the project on track.
Compliance wasn't an afterthought.
Most investment decisions happen on phones. We prioritized the mobile experience from day one and treated desktop as secondary.
We built test suites to simulate financial flows without risking real funds, then rolled out in stages with careful monitoring.
Financial apps face the strictest scrutiny. We started store documentation early and submitted for feedback before the final build, shipping a 5/5-rated app on first approval.
MVP in 3 months, production launch in 8 months. The platform now operates under a European investment license with automated monthly payouts.
Financial apps must work perfectly on mobile. That's where users make decisions.
In financial applications, regulatory compliance must be built in, not added later.
A project from scratch allows building the right architecture without compromises and technical debt.
An AI assistant can make platform interaction easier, but it doesn't replace solid technical foundation.
The codefunded team showed remarkable professionalism and flexibility in the face of rapidly evolving business requirements. On the technical side, they delivered a flawless solution and proved to be a rock-solid partner throughout the entire development of the application.
