What Clients Say About Us

Jani Muuronen - Talented

The Reactron team is a great long-term partner. They apply their expertise well and always advise the most efficient solution. Even when we need ad-hoc requirements, it was a breeze for them.”

"We got to know Reactron through their Innovation Voucher services, which enabled us to grow significantly faster because they provided us with the technical knowledge that we didn’t have. Reactron built a software prototype for our smart robot using React Native, which is a technology that they’re exceptionally good at. We’re glad to have them at the start of our journey because it helped us validate our ideas, test our robot, and solidify the foundation for our future robots.”
Co-Founder at Superflash
"Working with the Reactron team was a very positive experience. The team was earnest, hard-working, and diligent. They worked on everything from packaging our native SDK and npm packages to creating user interfaces and improving our overall architecture. Whenever your company needs to speed up your React Native development with true expert-level help, Reactron will not disappoint."
Mikko Virkkilä
CTO at Steerpath
"The team was flexible, patient, and meticulous. From our requirements, they even advised a more efficient solution, and they even delivered an additional bonus feature which made our solution more robust and reliable."

Tests to a software development team are like legs to a whole body that bears the weight of technical complexities in the pursuit of good-quality products. Without tests, the fast cycle of iterations and the market’s requirement of quick releases often seen in modern software development will easily overwhelm the business itself.
