The esperta Story

esperta was founded in Berlin in the beginning of 2020 but with expertise and experience of more than 30 years of extensive work in the world of electronics.

The founders of esperta come from completely different areas: Research, precision electronics, the production of electronic components and worldwide sales of products form the basis of esperta. There are also international employees from the areas of hardware development, software and firmware as well as marketing and social media. A competent team in logistics, purchasing and administration complete the workforce around esperta.


We are not a Start-Up company, but a group of experienced people setting up a new combination of working together.

The decades of international experience of all employees in these areas allow ideas that have long been available in patented form to be turned into reality.
