About Rento

Rento Innovations Oy is a full-service software development company of full-stack developers, designer, business analyst and project manager. We provide services such as tailor-made customer projects and IT consulting. We have deep expertise in development, QA & testing, UX/UI design and project management. We are passionate about what we do and our mission is to create our own product.

Rento Innovations was founded in 2015 just before Valentine’s day by three ex-colleagues Vesa, Tero and Mira. Mika and Andreas joined to give more dev power for us and our projects. We have laid-back management and everybody in the team can influence decisions. Rento headcount is yet rather small, but our experience and skills are huge. We have a desire to grow and we are currently interested to hire more developers. One of our super skills is making bad jokes, but we have also badass technical skills like you can see from below picture.


Vesa Nohteri

CEO / Business & project manager

20 years in IT-field and still loves every second of it. Experienced in both technical and management sides. Nowadays more in management side, but to satisfy his technical side, eagerly deep-dips into the Rento products. Passion for sales and marketing. Loves most of the people and would hug them often if he wouldn't be a Finn.

Mika Hamunen

Full stack developer

Experienced full-stack developer who writes nice clean tested code and is always interested to learn more and trying out different languages, frameworks and libraries. Also highly comfortable in designing and implementing infrastructure.

Andreas Lindroos

Full stack developer

A well-rounded web developer who has a slight focus on front ends written in Javascript. Excited to see more Javascript being used in mobile development. Enjoys writing end-to-end browser tests and coming up with new ideas.

Tero Kaarrela

CTO / Full stack developer

Experienced full-stack developer. "New tech" junkie and highly skilled developer, who just might be in love with POC's. Has excellent training skills and is able to explain his tech stuff in such a manner that even designer and sales understands. Loves to make techno.

Mira Aaltonen

Designer / Software tester

Passion for digital design. Bad UX makes her scream and cry at the same time. 15 years ago started as a dev, but soon realized that likes to break other developers toys more than to create the toys for others to break. Loves gadgets and thinks that if you don't have data, then it never happened. Good at Instagram stalking.
