Kaisa Nummela

Portfolio Owner, Digital Channels


I’ve always felt that you are very committed to helping us and always ready to work hard to get things done or solve any issues (even when SLA agreement has not been in place).

You are very skilled and competent in what you do.

You are really fast in developing new features or even applications when there is a need to have something ready extremely quickly.

Founder of diginomica.com

We get a powerful yet bespoke system that grows with our needs without compromising performance. 

The team works hard to ensure they understand requirements (and make us think carefully before committing!).

BRAINSUM helped us flip the maintenance/innovation cost profile so that we get much more innovation than was possible with the old system.

I have been working as an agile methodology advisor with the team for a couple of years.  Over my stint working with Brainsum, we've adapted our workloads while adjusting to high and low intensities.

It's been truly rewarding working with them: they have never regressed while employing a smooth and amazing persistence to keep on developing.
