About Tenacity
"Account management is the powerhouse of your organization"
What we believe in
'It's all about value'
The goal of account management is to deliver relevant value to customers.
When an account management organization is driven by value for customers, everyone gets what they need: The customer gets relevant value, the organization profits, the account manager an inspiring goal and the manager gets control
Mission
'An excellent account management organization for you.'
We make the account management process work for service providers. We set up, organize working methods and sharpen our vision on account management.
Because we have been focusing on service providers for more than 35 years, we know all the best practices and have developed several ourselves together with our customers. Account management for service providers is different than for product companies because services are different from products.

Our services
History
Tenacity is originally an American company. Tenacity means “tenacity”. This name reflects exactly what Tenacity was founded in 1986 for, namely helping managed service companies retain their largest customers. All insights, tools and methods that we implement for our clients all originate from the source: customers. From day one, Tenacity interviews decision makers at managed service customers about their reasons for choosing or firing their suppliers.
Now, more than 35 years and thousands of interviews later, our services have become much broader. We develop excellent account management processes for and with our clients. This creates control for managers and success for account managers. This results in profitable customers for life and profitable growth for our clients.
What the customers of all our clients worldwide say is still the source of our knowledge for developing products and services. Let's get acquainted, we are happy to share our experiences.
