Understanding between man and machine

Inspiration

The company was started by Sander Nagtegaal and Marcel Panse in 2016, with a mission that is inspired by a personal tragedy.

Sander is known to be an avid martial artist. About 4 years earlier, a severe accident happened in a Mixed Martial Arts (MMA) training session, resulting in a stroke that left him without the ability to speak for months. He avoided human contact and focused on computers entirely, discovering the limitations of digital communication from a unique perspective.

This ordeal made the two friends decide to devote their next startup entirely to improving the understanding between people and their technology.

Vision

Unless.com improves the understanding between man and machine, offering services that adapt digital communication to match the state of mind of individual people. Its real-time personalization platform lets you tailor your website messaging to each unique visitor.

Only one year old, the Unless platform now caters to over 6000 websites. Considering the multi-billion dollar, growing market for personalization, this is only the beginning.

And it does not stop here. Unless is now aiming at fully automated personalization, leveraging machine learning and artificial intelligence for a contextualized website response across the entire customer journey.
