Our Values

Driven by our customer’s success

Our customer’s success is essential to our own success. We aim to add value and exceed expectations with every customer interaction.

Brave & Bold

Think big, start small, go fast! We value people who take initiative and are willing to experiment on the path to greatness. We grow fast, fail fast, learn fast, and adjust on our way to success.

Always be Growing

It doesn’t matter where we come from, it matters what we are capable of as individuals. We believe that investing in employee’s growth means investing in the Company’s growth. We love the challenge that growth brings, we seek it out, and we thrive on it.

Respectful & Inclusive

We don’t believe in false hierarchy, we believe in the strength of an idea. Regardless of an individual’s background, experience or title, we value differences and everyone’s contribution.

Get S#!t Done

We thrive in a high-achieving environment where we hold ourselves, and each other, accountable to work as hard as we can. We value the need to balance this drive with the need to take time off and live full lives outside of work, in order to remain a high performance company.

Humble & Grateful

We acknowledge our past successes and are appreciative of where we are now. We respect the work that has been done, and the work that needs to be done to push us beyond what we know is possible.

Sound like a good fit?

With more than 30 years of experience in both M&A transaction and integration activities, I saw how poor the generic tools for M&A were . That’s why we founded Midaxo. Our mission is to help companies succeed with their M&A with one easy-to-use, comprehensive and intuitive solution.
