We build the software your business runs on.
Guava designs and builds custom web apps, mobile apps and internal systems. From the first prototype to launch, and for years after. Precise engineering, no shortcuts.
Custom software, end to end.
All servicesWeb applications
Web apps engineered to stay fast and maintainable as they grow. This is the core of what Guava does.
Mobile applications
Mobile apps for iOS and Android that feel native. One codebase, one backend, one product.
Information systems
Custom internal systems that fit how your business actually runs. Dashboards, workflows and data in one place, not across ten spreadsheets.
AI development
Practical AI grounded in your data. Assistants, automation and integrations that save real hours, not just demo well.
Prototyping & MVP
A functional MVP that proves the idea before the budget scales. Analysis first, code second.
Support & maintenance
After launch we stay on. Monitoring, tweaks and support that keep your product running smoothly for years.
The proof is in production.
Booking platforms, internal systems, campaign websites. A selection of projects that have been running in production for years, and the clients who trust us with them.
Other professionals build on our code.
Alongside client work, we maintain a handful of open-source libraries. Software teams around the world have used them over 1.6 million times. When other experts keep reaching for our work, that says more than any sales pitch could.
A small team, obsessed with getting it right.
Guava is a Czech software studio. We take the time to understand the problem before writing a line of code. It shows in the products we ship and the clients who stay.
- Fixed scope and transparent pricing. You know the cost from day one.
- Iterative delivery. You see progress and give feedback throughout.
- Long-term support. We don’t disappear after launch.
How we work.
Five steps, no surprises. You’ll know what to expect and what it will cost before development starts.
“If I had an hour to solve a problem I’d spend 55 minutes thinking about the problem and 5 minutes thinking about solutions.”
Discuss your project
Personal meetingWe discuss the issues you encounter and the outcomes you’re after. You leave with a rough timeline and a budget range.
Analyze, design & prototype
According to project sizeWe analyze the problem first, then deliver a working MVP. Thinking before coding.
Development
According to project sizeOnce the prototype is ready, we work iteratively. You see progress and give feedback throughout the whole process.
Testing & QA
Quality assuranceAutomated tests, real-device checks and final polish. Nothing ships until it works.
Launch & support
Ongoing partnershipOnce everything is ready, we launch. Monitoring, tweaks and support keep it running smoothly for years, and when the roadmap grows, we move straight into agile development, sprint by sprint.

We’ll come back with an honest take on scope, timeline and cost. No obligation, no sales pitch.
