Product Builder

Hey!

I'm Raitis, a product builder in Riga. If something should exist, I make it.

Portrait of Raitis Cakstins

I started in IT support and worked my way up to leading a dev team, until I realized I'd rather build the thing than manage around it. So now I build: software, automations, and websites, the kind companies usually rent or outsource, made to keep.

And it never stopped at the day job. I co-founded Ars Ratio and Mandet, and I ship my own products on the side, across AI, ecommerce, and the tools businesses quietly run on. My own ideas, other people's problems, same instinct: take it from idea to done.

Get in touch

I'd rather make something than talk about it. Anyone can ship a demo. The real work is making something that still holds up on the hundredth day, in someone else's hands. So that's what I build: things made to keep.
