The workshop “Briefing: more than a short conversation” was perfect. Petra Wolkenstein presented exactly the right mix of well-founded infotainment and training in applicable expertise.

Petra used her wealth of B2B negotiating experience to help our lab companies find ways to grow and share the pie with Arsenal. Based on the relationships they’d developed with the business owners, and the quality of their offers, half the companies reached agreements to enter commercial pilots. That speaks volumes for Petra’s value.
