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

Arnaud has more than 10 years of experience in the customer relationships field.

He began his career by leading a customer service team in a telecommunications company. He subsequently worked as a Sr. Strategic Solutions Consultant at Zendesk, in London. In this role, Arnaud partnered with the Enterprise Sales team to develop account and opportunity strategies. He also was instrumental in creating an ROI model & analysing the gains of implementing Zendesk, while building and demonstrating PoCs, and leading the scoping of professional services packages.
Overall, Arnaud helped close deals for a total of over $3M ACV in 2016, and witnessed the highest win rate with about ~60% of deals touched that closed. During his time at Zendesk, Arnaud won “Over Achiever” and “Enabler of the Year” awards. He worked on the biggest EMEA deals such as Tesco, Booking.com, Just Eat & Lampiris.

Arnaud’s goal is to understand a client’s business needs, and transform that into some form of solution definition, meeting or exceeding their measurable business goals for customer service. He aims to ensure clients understand the technical and business value the software can deliver.

He is currently the founder of his own consulting firm, ADT Consulting.
