Measurable, self-organized work, and long and happy customer relationships are the cornerstones of getting things done the Montel way. Our full-stack developers become a natural extension of your own technology team or help you build one from scratch.

Our projects are billed flexibly on a day-to-day basis with real-time customer access to monitor progress. With us, you can always be in direct contact with the lead developer for maximum effectiveness.

The development workflow can be further complemented by MontelCare , our 24/7 cloud management service with a full guarantee.


Our software architects and full-stack developers have decades of experience in designing and creating commercially successful software. Our developers have wide-ranging expertise but there are some things that we do better than others.


We master a variety of platforms and technologies, and will gladly help you choose the tools that best serve your needs.

We are one of the leading Python development companies in Finland but also have deep understanding of especially Javascript, Ruby and Elixir. Django, Rails, Express and Phoenix are some of our weapons of choice when it comes to frameworks. Vue and React are our current favourites to create beautiful frontends. Just to name some of the tools we consider to be the best at the moment.
