Our rich heritage

Since 2016 we have operated as one joint Tack TMI Network, under the stewardship of Gi Group, who acquired the businesses at that time. This strategic move by Gi Group was designed to accelerate its learning culture (linked to their values), provide Tack TMI’s solutions to their existing clients, and provide Tack TMI with the conditions to further accelerate its growth and reach.

Prior to this time, Tack and TMI operated independently – each with a unique history and DNA, but shared beliefs that hold true today. As Tack TMI, we provide the best of both worlds together, in our motto. We believe in the individual.

The UK’s first Sales Training Company, founded on a focus on customer-centricity – brought to life through the “You, We, I” concept.

Tack began with a small UK family business back in the 1930’s. George Tack – an engineer, and his brother Alfred – a natural salesman, established ‘NuAire’ in 1937, producing and selling ventilation and heating systems.

Employing a large team of commission-only salespeople, the Tack brothers developed an internal sales training programme that yielded outstanding results. Word of ‘Tack’s Training’ travelled fast within UK industries and many people from different businesses came to observe and learn professional selling skills, centred on the customer-centric “You, We, I” concept.

The entrepreneurial brothers recognised a new market for sales training and decided to share their expertise officially, through the foundation of an independent training and development business. The ‘Tack School of Salesmanship’ was established in 1948.

A holistic approach to personal development, authoring your life and story in an intentional way.

Time Manager International, TMI, was founded in Denmark by Claus Møller in 1975. He believed that it is the emotional development of individuals that is the secret to transformation. Since its foundation, TMI has directly influenced and inspired more than 6,000,000 people worldwide.

TMI has changed the relationship between many service providers and their customers – our training and communication methods helped SAS (15,000+ people trained) and British Airways (36,500+ people trained), transform their service and profit performance in the 1980’s.

In the 1990’s TMI evolved into a consultancy inspiring and enabling culture change – working with people to translate vision, purpose, core values, brand values & personality into sustained new ways of thinking, acting and behaving.

Tack TMI Switzerland was born from the partnership between Gi Group, one of the top 10 HR and professional services companies in the world and Interiman Group, the leader in staffing and HR solutions in Switzerland.

Thanks to our strong and successful presence in the Swiss market for over 20 years, we built a strong level of trust and expertise for understanding our customers’ needs and providing the right diagnostics and solutions for them.
