High-Tech Gründerfonds secures another successful exit – EH-D acquired by Bosch Rexroth

June 29, 2021

  • By taking over an extensive technology package, Bosch Rexroth will increase its range of electrically driven, servo-hydraulic compact axes
  • EH-D is the ninth HTGF portfolio company to be acquired by a HTGF fund investor
  • HTGF and Bayern Kapital took up stakes in EH-D in 2010 as part of a seed financing round 

Bonn, 29 June 2021 – High-Tech Gründerfonds (HTGF) has achieved another successful exit, with the EH-D assets being sold to Bosch Rexroth. The company’s site will be retained, while the employees will be transferred to Bosch Rexroth. EH-D is the ninth HTGF portfolio company to be acquired by a HTGF fund investor. Robert Bosch GmbH has invested in all three HTGF funds. HTGF is a seed investor for tech start-ups, but it also acts as a platform of exchange between corporations, SMEs and start-ups.

By taking over the companies’ special compact axis know-how, we’ll be able to offer our customers unique drive solutions for all power classes that are leading both technologically and economically. In addition, it will help to further drive the electrification of industrial applications. The addition to our portfolio will also help us in our strategy to win customers in other sectors such as the food industry.

Dr. Steffen Haack, Member of the Executive Board of Bosch Rexroth AG responsible for Development and Head of the Industrial Hydraulics Business Unit

The axes have a number of special technical features. Their internal gear pumps are suitable for 4-quadrant operation, i.e. operation in both directions as a drive or a brake. The oil-flushed synchronous motors allow targeted heat dissipation and thus extended operating ranges with no need for secondary cooling measures. And the specially developed compensators for EH-D compact axes help to balance differential volumes and compensate for internal leakage flows or temperature fluctuations in the fluid. High-Tech Gründerfonds (HTGF) and Bayern Kapital took up stakes in EH-D (formely Böhner-EH GmbH) back in 2010 as part of a seed financing round.

We’re extremely proud that founder and CEO Kai Böhner has succeeded in revolutionising electrohydraulic drives on the basis of the investment in 2010. That’s why we’re all the more delighted to see that this achievement has convinced Bosch – a HTGF investor that has continually invested since day one – to acquire EH-D through Bosch Rexroth and integrate it into its own range of products. And for this we’d like to say, congratulations!
