The sessions were very useful in dissecting our key KPIs (Revenue and CLV) into the underlying metrics and their interrelationships. By building KPI trees and customer journeys, I gained insight into the types of drivers that can accelerate certain growth.

Amazing workshop. Thanks a lot. Really helped me (re)organising my planning, agenda and email with loads of practical tips. But most importantly, a wakeup call to change my mindset towards tasks, priorities and planning.

Ewoud is a smart guy and a great sparring partner. He adds the most value in solving growth challenges in an abstract way and in unravelling the principles behind the problem. In this way, Ewoud helps to structure growth and finds growth opportunities.

I really loved the combination of theory with the hands-on material and tools that made everything very actionable. This course is relevant for anyone working in B2B: whether you are new to growth or want to optimize your marketing or sales strategy to reach your business goals. Even with my background in growth, I definitely learned new stuff.  And for those who don't know Ewoud, he's one of the best Growth Experts I know!
