This year we were good again.

A tree-mendous year!

The Seven2one year in review 2021

We were good at embracing the new,
good at doing things differently,
good at making an impact –
and always good at serving our clients!

What about you? In any case, you were good to work with, and we wish you good health and good fortune in the year ahead!

What a crazy year!

We wore masks, followed social distancing rules and exhibited great flexibility – and yet the coronavirus is still here. However, we also made the best of the situation together, worked very hard and chalked up many successes.

These are great achievements, and a huge thank-you goes out to our staff. A second big thank-you goes out to our great clients: for their loyalty and great cooperation over the last 12 months. We very much appreciate all of this.

You truly earned your holidays, so please enjoy your time off, do what you can to recharge your batteries after this extremely eventful business year and get a good start in 2022.

We are looking forward to being at your side again as we provide “more than software”!

On behalf of the entire team
Carmen Bickle and Jan Marco Heinz
