A phone call from Jaap: from consultant to sales

A phone call from Jaap: "I'm moving from consultant to sales," he said. "But honestly... I don't quite know how yet."

Jaap had just started in his new sales role at Mobilee, a consultancy firm. He wanted to do it properly: no tricks, no smooth talk. Just professional, honest and with results.

Together we started the Sales Excellence Programme in three steps:

Step 1: Online Sales Excellence Training. Jaap discovered what really works in B2B sales. No tricks, but insights that helped him make more impact straight away.

Step 2: One-to-one deep dives in Castricum. A session at my office every month. We dug deep into his customer cases.

Step 3: Phone support. Whenever things got tense, he called. Being able to switch quickly brought calm, and often immediate results.

Jaap's response: "That switch from consultant to sales took some getting used to, but your guidance was superb. Honest, sharp and always with room to do it my own way."
