tiag joins the Sequotech group

Jul 13, 2026

Sequotech announces the addition of tiag (Teleinformatik Services AG) to the group. This move enables the group to strengthen its presence in German-speaking Switzerland and expand its portfolio of comprehensive IT services for small and medium-sized businesses.

With the addition of tiag, the Sequotech group now comprises ten companies and employs nearly 400 experts in Switzerland and Germany. Since September 1, 2024, Alain Arnold has been leading tiag, formerly Teleinformatik Services AG, succeeding his father, Claude Arnold. This new phase in the company’s development aims to leverage the group’s expertise and Sequotech’s collective resources to offer expanded opportunities to clients and employees. The team will continue to uphold its usual high standards in delivering quality IT services to its customers.

tiag will continue to operate with its existing team and management, while benefiting from the expertise and collective resources of the Sequotech group. At the same time, tiag’s management will become a shareholder of the group and benefit from the company’s long-term development.

Since 2020, Sequotech has pursued an ambitious growth strategy, made possible by an investment from Verium, a Zurich-based multi-family office.

Comprehensive IT solutions since 1999

Since its founding in 1999, tiag has established itself as a reliable technology partner for Swiss SMEs. Based in Zurich Oerlikon district, the company now offers a wide range of solutions, from managed services for cloud and IT infrastructures to Enterprise software, modern work environments, and VoIP telephony. Increasingly, tiag also supports its clients on topics such as artificial intelligence, related use cases, and governance issues, positioning itself as a comprehensive partner that continuously evolves alongside its clients.

A solid operational foundation and customer proximity

With 40 employees, more than 650 clients, and over 5,000 monitored systems, tiag has a strong operational capacity. Its personalized approach, forward-looking solutions, and proven service quality have made the company a recognized partner in the SME market in German-speaking Switzerland. The teams, the office location, as well as the usual service and personalized support remain unchanged for all clients.

Reactions within the group

Alain Arnold, CEO of tiag: “With this new step alongside the Sequotech group, we are reaching a milestone in tiag’s development. For our clients, everything remains the same on a day-to-day basis: the same points of contact, the same level of personal attention, and the same standard of quality. At the same time, behind the scenes, we benefit from increased expertise, resources, and efficiency to support our customers even more comprehensively.”

Daniel Neuhaus, CEO of Sequotech: “We are very pleased to welcome tiag to the Sequotech Group. For more than 25 years, this company has embodied precisely what our group has also set as its mission: to safely guide the backbone of the Swiss economy—our SMEs—into the future through a 360-degree IT solution. Together with the entire tiag team, we will go even further for our clients.”

Consistent pursuit of growth

With this step, Sequotech is resolutely pursuing its growth strategy and thereby strengthening its position as a leading Swiss group in the IT services sector. The group brings together companies that benefit from shared resources, synergies, and an expanded range of services.
