Fragaria

Fragaria is a Prague-based software development firm founded in 2012 with more than 10 years of experience building web applications, single-page applications, and mobile apps. The company operates with a team of senior-level developers and positions itself around SCRUM methodology and agile development. They work with international clients and maintain fluency in English across the team.

Their portfolio spans fintech (banking APIs and personal finance apps used by 200,000+ clients), travel tech (booking systems and portfolio management platforms), civic participation platforms, blockchain initiatives, and open-source projects. Notable clients include Kiwi.com, Komerční banka (part of Société Générale Group), Česká spořitelna (Erste Group), and Democracy 21.

Services and capabilities

Fragaria's work breaks into several areas. They build full-stack web applications from frontend through backend—the company has handled Angular and React frontends paired with Python Django and Node.js backends. They also do infrastructure work: they scaled a central logging facility at a major Czech bank using Elasticsearch, Kibana, and Kubernetes. On the infrastructure side, they've managed deployments to AWS and worked with Kubernetes for scaling.

The firm contributes to open-source (they maintain Karmen, a 3D printer controller) and has worked on blockchain projects—specifically Ethereum smart contracts and decentralized platforms. They've also undertaken frontend strategy work, helping Komerční banka update its tech stack for modern interactive web apps.

For specific outcomes: Fragaria delivered an e-voting platform for Democracy 21 that handled civic budgeting decisions in Říčany (5 million CZK budget votes) and New York City ($30 million budget). A related project, the Prezident 21 internet voting game, reached 3 million visitors. They built Moje zdravé finance, a financial management app within Česká spořitelna's George banking platform, which serves 200,000+ clients and is used by bankers in branches across the Czech Republic as a financial counseling tool.

Notable work

Kiwi.com: Fragaria became an IT solutions supplier for the travel startup, contributing development and project leadership across several smaller projects. They work in an agile cadence and handle integration of product increments into existing infrastructure.

Winding Tree: The firm is part of a distributed development team researching and implementing an open-source platform using Ethereum blockchain to disrupt travel distribution and reduce middlemen. They handle both research and developer-facing tooling to lower the barrier to entry.

Fast (Komerční banka): Fragaria created the entire frontend development strategy for new web apps (both internal and external) at the bank, modernizing their tech stack to handle increased demand for interactive web applications.

Logman (Komerční banka): They built the central logging facility handling logs from dozens of internal systems with varying requirements. The solution uses Elasticsearch and Kibana with Kubernetes scaling to manage large volumes while maintaining maintainability.

Democracy 21: As sole tech supplier from January 2015 to June 2018, Fragaria delivered an e-voting platform that handles security, scalability, and reliability without compromise. Citizens in Říčany and NYC have used it to decide on budget allocation.

How they work

Fragaria uses SCRUM methodology with sprint-based development. At the start, they agree on team composition, sprint length, and overall timeline. Each sprint involves task definition, selection, end-to-end implementation (including analysis, UI design, development, testing, and deployment), acceptance, and retrospective. At the end of each sprint, the client receives a functioning version of the application, allowing for rapid priority shifts. Tasks are accepted only when the client is 100% satisfied. Contracts are flexible with a 1–3 month notice period, and the first sprint typically produces a functional prototype. If dissatisfied, clients can reconfigure or exit. The company guarantees handoff documentation so other teams can continue the work.
