We build, teach and operate software
Optersoft is a software consultancy in Barcelona. We help companies start on new technology — Rust, Python, Kotlin Multiplatform, AI — train the teams that will own it, and build the software they need. The products we run ourselves are where we prove it first.

Start on new technology with a team that already ships it
We help companies adopt Rust, Kotlin Multiplatform, Python and AI without betting the roadmap on it, we train the teams that will own the code, and we build what they need with them.
Technology
What we build with, and what we run
Open tools you can use today, the platform our own products run on, and the material we teach from. All of it in production, on our own products first — that is where we prove it before we bring it to your project.
The apps for peopleAbout
Who you would actually be working with
There is no account manager here and no layer to be handed down to. The people who agree the scope of your project are the people who build it — named, with faces, on one page.
