Custom software & SaaS development
We build internal systems and public-facing applications
We turn ideas into working products: web apps, SaaS platforms, mobile apps, and the AI features inside them. We build them properly and ship them to production.

From design and launch to ongoing development.
Built for the job, not from a template
We don't start from a prebuilt recipe. We start from your goal and build what actually fits your day-to-day operations.
What matters isn't visible
What users don't see matters most: , integrations, and that keep performance and stability in place.
We don't stop after launch
Launch is not the finish line. After release, we handle fixes, tuning, and further development based on the agreed scope of work.
What we do
Software development, end to end
We build public-facing and internal applications of all kinds, from to platforms, web and mobile apps, and AI features. Pick the closest fit or tell us your idea.
Have an idea for what to build?
We work with companies that need real software built and shipped, and often maintained afterwards. Tell us what you are planning and we'll tell you honestly how we'd approach it.

Common questions
What does Nextrey build?
Custom software: web applications, SaaS products, mobile apps and AI features. We take a product from the first idea to production, and we can keep maintaining it afterwards. We build for whatever market you're targeting. Your users don't have to be in Europe.
How much does a project cost?
Every product is different, so we don't sell fixed packages. After a free first call we scope the work and give you a fixed quote, so you know the number before we start. As a rough guide, a first version is usually a multi-month project; the cost depends on scope, integrations and how polished it needs to be.
How long does it take to build?
Most first versions take a few months (often 3 to 9), depending on scope. You get a realistic timeline after the first conversation. We'd rather commit to a date we can hit than an optimistic one we can't.
Do you work with companies outside the Czech Republic?
Yes. We work remotely with clients wherever they are, and your product can target any market. Being an EU company simply means we can handle GDPR and EU requirements cleanly when they apply to you.
Do you maintain the product after launch?
Yes, it's one of the main reasons clients stay with us. We fix issues, ship updates and keep improving what we built, or hand it over cleanly if you have your own team. We run our own SaaS in production, so we build with the long term in mind.
Why work with Nextrey instead of a bigger agency?
We have a real product in production to point to, not just a portfolio of mockups, including parts most teams wouldn't bother with, like turning a clunky government licence registry into a couple of clicks. We build the unglamorous engineering that keeps a product alive. You get depth and ownership of the result, not a sales pitch.
