Ralf Dümmel (55) mourns the loss of FLÜWA founder Karlheinz Voll on Instagram. The master bricklayer and civil engineer presented his invention, “the spirit level with wings”, on the VOX founders’ show “Die Höhle der Löwen” in April 2021 and concluded a deal with the entrepreneur. Now “dear Karlheinz has unfortunately passed away,” writes Dümmel in an emotional post on Instagram, which he found very “difficult”.

Dümmel was fully enthusiastic “as an entrepreneur”. “But it’s much more important that I got to know such a special person and gained a friend in life,” writes the lion. His thoughts are with Voll’s family and wish them “a lot of strength”.

“Take care, Karlheinz, thank you for the many great moments together, I will never forget you,” Dümmel closes his post. He also shared a black and white photo in which he poses with the founder and his invention in front of a “Lion’s Den” poster.
