“Koppel’s empathy with the IT industry makes all the difference.”

“Koppel Services gives us specifically automation advice, which make our processes better” Remko van den Berg, founder of NOA

“Always be upfront even where it may not do you much good in the immediate term – that is what I call ‘the Koppel way’.” André Groot, founder of BVCM
