KOALA42

KOALA42 was founded in 2018 and is based in Czechia with offices in Prague and Zlín. The firm builds custom web and mobile applications, internal systems, and AI solutions for businesses across manufacturing, logistics, fintech, and SaaS. They have completed 70+ projects and maintain a 5.0 Google rating. The team works across both startups raising capital and established mid-market firms, positioning themselves as bridge-builders between business needs and technical implementation.

Services and capabilities

KOALA42 offers four primary service lines: mobile app development (iOS via Swift/Objective-C, Android via Kotlin/Java, plus cross-platform frameworks like Flutter and React Native), web application development, AI solutions, and internal/enterprise software systems. For mobile, they handle everything from App Store and Google Play distribution to long-term maintenance post-launch. On the web side, they build applications for e-commerce, document automation, supply chain optimization, and real-time production monitoring. Their stated approach includes UX/UI design paired with backend architecture, API development, DevOps, and CI/CD pipeline setup.

They also offer strategic consulting before development begins—analyzing business problems and sometimes recommending off-the-shelf or open-source alternatives if custom development isn't the right fit. They create clickable UI/UX prototypes before writing production code, positioning this as a way to validate assumptions and reduce rework.

Notable work

Named projects from their portfolio include Talsec (a security shield for mobile apps), Onepos (order management for payments platforms), Qapline (truck fleet logistics management), and EWA (a waste-sorting incentive app). A client testimonial from Jaroslav Hořejší at Dřevěné konstrukce states the software "gives us an overview of production" after helping track and document manufacturing. Another from Eva Čejková (Testuj.to CEO) praises their ability to "find the most efficient paths and flag risks and costs." Pavel Kučera, formerly CTO at Avast, described them as a "flexible and agile team not afraid of new technologies."

How they work

KOALA42 uses agile methodology with 14-day sprints. Initial consultation is free. After kickoff, they run a brainstorming and analysis phase, then build a functional UI/UX prototype for client sign-off before coding begins. During development, automated testing scripts validate code quality and simulate user workflows. Clients receive a functional demo on a test server at the end of each sprint and can adjust requirements based on progress. They offer two pricing models: monthly time-and-materials billing with work summaries, or fixed-price projects negotiated upfront. Timeline for an MVP is often cited as three months. Post-launch support includes bug fixes, optimization following OS updates, and long-term maintenance—they explicitly state that engagement does not end at deployment.
