1997 - 2000

Adia and Ecco merge to form Adecco. Two of the world's top three personnel services firms, with complementary geographical profiles, merge to form a strong global leader with annualised revenues of over EUR 5.4 billion. Operations are combined to form a global network of 2,500 branches. The new Company has an exceptional range and quality of services. The core staffing business places around 250,000 people in work each day.
Sales topping USD 1 billion in 1986 make Adia the European leader. Its success is partly down to a focus on quality and high-value services. The 1990s see a growing trend towards specialised skills, e.g. accounting and word-processing, including in-house training programmes.
Further acquisitions from the late 1980s onwards strengthen base in highly skilled, specialised fields. Also, a move into social programmes focused on more mature workers.
In 1991, recognising the importance of the industry's role in job creation and its growth potential, Klaus J. Jacobs invests in Adia en route to becoming majority shareholder.

Pestalozzi and a phase of expansion by acquisitions begins. In the next 12 years, Adia buys over 85 companies, tripling in size and gaining footholds in more than a dozen countries, including France (1975) and the UK (1977), where it buys the market leader: Alfred Marks Bureau Ltd.
Further expansion overseas, including Australia, New Zealand, Japan, Hong Kong and Canada. Meanwhile, Ecco is focusing on its home market. By the mid-1980s, it is the market leader in France, a decade later world no. 2. The growth of both companies is part of a wider trend: temporary staffing becomes the world's third-fastest growing industry in the 1980s. Adia's Pestalozzi states in 1985: "We want balanced growth; we want to be known as the best, rather than the biggest in our markets."
Adia SA is founded in Lausanne, Switzerland, by Henri Lavanchy. The firm grows rapidly in its home country before expanding abroad.
Philippe Foriel-Destezet founded Ecco in Lyon. By the early 1980s, Ecco is France's largest supplier of temporary personnel.
