We are Interjektio

It started with two coders from Oulu

Interjektio Oy was founded in 2019 in Oulu by experienced software developers. Behind the company are Antti Haapala and Rainer Koirikivi. Although the company itself is young, the combined expertise spans over two decades of demanding software projects, databases, and distributed systems.

More great people and talented developers

Originally, Rainer and Antti each ran their own solo companies and worked on similar projects. As the workload grew, they founded a joint company and hired their first team members. Clients came through word of mouth, driven by consistently high-quality work.

Today, Interjektio employs 6 software developers. Our office has plenty of space, but for some reason everyone prefers to work together in one large room. Work practices are flexible, and for relaxation the office has it's own bar, a pinball room, and a gym.
