Arnaud [ah-r-n-oh] de Theux

About 10 years experience both running customer support teams, and then selling customer service software — in each scenario with energy and passion.

My goal is to understand a customer's business needs, and transform that into some form of solution definition, meeting or exceeding their measurable business goals for customer service. I aim to ensure customers understand the technical and business value the software can deliver.

While working for Zendesk, I helped closing deals for a total of over $3M ACV in 2016. My win rate was one of the highest with about ~60% of deals touched that closed, and I worked on the biggest EMEA wins such as Tesco, IBM, Booking.com, Just Eat, and Lampiris.
Awarded with "Over Achiever" and "Enabler Of The Year" awards.

I have now founded ADT Consulting, a consultancy firm specialising in helping businesses digitise, streamline and optimise their customer service operations.
