We build & enhance softwarewith .NET and AI.

Smaltsoft is a software house founded in 2019 with a simple idea: build great software, skip the fluff. Based in Poland and serving clients worldwide — across Europe and the United States — our team of engineers, architects, and AI specialists works with companies of all sizes, from startups finding their footing to large enterprises scaling their systems. We focus on AI and .NET because that's what we know best.

We're engineers first. We write clean, reliable code and use AI where it actually helps, not as a buzzword on a slide deck. Whether it's a custom .NET application, an AI-powered product built with Azure AI and Semantic Kernel, hands-on training or technical consulting, we build things that work and ship them fast.

How we work is simple: no unnecessary meetings, no bloated processes, no surprise invoices. Whether you need a dedicated development team or a single expert consultant, we tell you what's possible, how long it will take, and what it will cost. Then we deliver. That's it.
