Strategy & Technology

we build software for fintechs & startups.


We build your apps

To make your web and mobile projects a success, we’ve learned from experience to use a pragmatic, agile approach straight away, focusing on the rapid development of successive operational versions that become increasingly complete. That’s why we see ourselves less as ‘developers’ and more as ‘doers’.

One price, one delivery date

Our pragmatic approach can also be seen in the way we organize our collaboration with you. Our rates are not calculated per hour or per working day, but rather as a single price per project. We analyse your needs, commit ourselves to a delivery date and a budget, and that’s what we stick to, as a point of honor.

About us

We began working as software developers back in the days when the internet was just starting up, in the middle of the 1990s. We have lived through all the trends and worked in countless languages and technologies. This unique experience has given us the capacity of hindsight, and another way of looking at things that is rather more analytical and unaffected by passing fads.

Our values

Our decision to pool our resources within extHand is based on our desire to have free rein in working the way we want to. We aim to bring you solutions that are rooted in the values we uphold:

Delivering what we promise

Real passion for our profession

Transparency and keeping an open mind

Motivated by these values, we are confident that we can make a difference. Our mission is to provide you with innovative solutions so that your project can develop its full potential.

Our technologies

We don’t believe in ‘Swiss army knife programming’. The technologies we have selected are reliable, tested, stable and effective in the long term. We have even learned to master them. Although a few of our choices might surprise you, they were not made lightly. They are based on a clear understanding of the reality of start-ups and of the Fintech universe. We are willing to bet that, like all our clients, you will agree with us once we demonstrate to you the reasons for our choice.
