Custom software & SaaS development

We build custom software that holds up in production

We turn ideas into working products — web apps, SaaS platforms, mobile apps and the AI features inside them — built properly and shipped to production.

Why Nextrey

Built properly, shipped, and supported

01

Built for the job, not from a template

We start from your problem, not a boilerplate. Whether it is a web app, a SaaS product, a mobile app or an AI feature, we design the architecture and build exactly what the task needs — one product or several services.

02

We build the parts you can't see in a screenshot

The difference between a demo and a real product is everything users never notice — data models that hold up, integrations that don't break, reliability under load. That unglamorous engineering is the work we care about most, and it's why what we ship keeps working.

03

We don't disappear after launch

Shipping is the easy half. After launch we stay on as the team that fixes, updates and improves what we built — so your product keeps moving forward instead of quietly rotting once the first version is out. Staying involved after launch is one of our strengths.

FAQ

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.

Have something to build?

We work with companies that need real software built and shipped — and, just as often, maintained afterwards. Tell us what you are planning and we'll tell you honestly how we'd approach it.
