steezr

Prague, Czechia

We design and build custom software in Prague. And we stick around.

We're steezr, a small, founder-led software studio in Prague. Johnny, our founder and lead engineer, started out building websites alone in 2020. Today we're a team of six. We grew slowly and on purpose, and we still work directly with the companies that hire us. One senior team handles brand identity and design, custom platforms, web and mobile apps, Shopify e-shops, cloud/devops, security, AI integrations and process automation. The people designing your product are also building it. You talk to them directly, in English or Czech. There are no account managers passing messages between you and the work. For ajedeš, we built a custom platform that runs a car-trading business end to end. Automation and AI took over intake, valuation, photo edits and customer support. We add AI where it earns its place, and we'll talk you out of a bad idea if that's what the project needs. After launch, we often stay for years on monthly maintenance retainers and keep shipping new projects for the same clients. Most of our work still comes from referrals and returning clients.

Description

We build web platforms, apps and internal systems from scratch around your business, database schema to last pixel. Tools chosen to fit: Next.js, React, Node.js, TypeScript, Python/Django and Go. Clean, documented APIs make the next integration a small ticket rather than a rewrite. We write code we'd happily hand to the next developer, even if that's not us.

We design interfaces people get on the first try. We interview users and study heatmaps, then run usability tests to inform every design decision. Our Figma design systems include components and tokens, with guidelines for using them. The same team designs and builds, so nothing gets lost between the Figma file and the finished product.

Team

6 members in steezr's team

Storysteezr started in 2020 as Johnny building websites from a flat in Prague. No pitch decks, no sales team. Clients kept coming back and sending their friends, and most of our work still starts that way. We grew slowly and on purpose into a small senior crew. You talk to the people who build your product.
