Successful together.

We are proud of our successful customers. And of our development and OEM partners.

Pitting people against one another only helps the other side. That is why we practise working together.

If we’re honest, the word „partner“ is overused in business. As soon as two people have exchanged their email addresses, they call themselves partners. That’s why we’d like to make it clear right from the start: every partner on this site is a genuine partner.

We therefore regard our customers as partners and support them far beyond simply supplying the software. After all, only successful customers are long-term customers. We also work with software partners who market our technology as an OEM version under their own brand names.

And last but not least, we work alongside law firms to develop bespoke solutions. These so-called development partners bring their specialist knowledge, gained from day-to-day practice, directly into our software.

Customers

Whether they are SMEs or large corporations, we support our clients with tools, expertise and outstanding support.

OEM partner

Not everyone can specialise in everything. That is why many software manufacturers turn to us for help with specific specialist areas.

Development partner

Only real users know what their tool needs to be capable of. That’s why we work with several law firms.
