Who we are!
The JESAKO company was founded in 2020 by Sascha and Jeanette Koltzenburg because we were looking for a way to combine family and work as closely as possible.
company name
JESAKO thus also stands for SAscha JEanette KOltzenburg
The love of family, technology and creativity, but also the usable space allowed this idea to mature in us.


Our team
We are now an interdisciplinary team of mechanical engineers, hardware and software engineers, industrial and product designers and intellectual property rights specialists.
What we do!
My wife and I have three children and are also active as marriage coaches, a great passion of ours. I have been an experienced mechanical engineer for more than 25 years and manage the company JESAKO together with my wife.

We are both convinced Christians and believe in the God of the Bible and his Son Jesus Christ. The more I (Sascha) learn and get to know about the interrelationships of our complex living space, the more I know that chance could never have created something so grandiose. The precision of the regulatory and life mechanisms amaze me every time and leave me in awe.
