Deloitte Switzerland continues to invest heavily in innovation and people despite tough economic climate

Deloitte Switzerland generated net revenue of CHF 586 million in the 2024/2025 financial year. The slight decrease compared with the previous year reflects the widespread investment uncertainty, which has also had ramifications for the consulting sector. The Audit & Assurance and Tax & Legal business lines continued to grow in the reporting year, and Deloitte kept up its strategic investments in its employees, artificial intelligence, global centres of excellence and society at large. The company also contributed to sustainable development, with over 400 new hires, investments of almost CHF 2 million in society (+28 per cent), over 12,900 hours of volunteer work, and industry-leading net-zero targets for 2040.

The audit and consulting company Deloitte Switzerland generated net revenue of CHF 585.6 million in the financial year ending 31 May 2025. A complex economic environment characterised by geopolitical and trade policy challenges and constantly changing regulations, including on tariffs, artificial intelligence (AI) and sustainability, led many companies to postpone or scale back major investments.

This affected the Advisory service segment in particular, which accounts for a significant share of Deloitte Switzerland’s business and recorded an eleven per cent decline. The Audit & Assurance and Tax & Legal business lines recorded further growth, with an increase of around two per cent each. This trend was driven by rising demand for support in navigating increasingly complex regulations – in finance and sustainability, as well as in national and international tax matters.

“The past financial year was dominated by widespread geopolitical and economic policy uncertainty, which led clients to invest more cautiously,” says Reto Savoia, CEO of Deloitte Switzerland. “This uncertainty was exacerbated by stalled reforms both in Switzerland and some of its major trade partner countries. For our clients, this means having to navigate a highly volatile environment while facing increased cost pressure,” he adds.

During the reporting year, Deloitte therefore helped businesses and other organisations to implement the OECD Global Minimum Tax, answer complex questions about customs and tariffs, make necessary improvements to their supply chains, introduce AI, navigate the rapid pace of sustainability regulation, refine strategic transactions and prioritise digitalisation projects.

More streamlined business structure in response to client needs

In light of the drastic changes in the market environment both in Switzerland and further afield, Deloitte has simplified its business structure and adapted it to its clients’ needs. Since 1 October 2024, the company has offered its multidisciplinary services across four business lines: Audit & Assurance; Tax & Legal; Strategy, Risk & Transactions Advisory; and Technology & Transformation.

AI: from pilot projects to scalable solutions

Deloitte Switzerland continued to invest heavily in innovation during the past financial year. The focus is on harnessing AI on multiple levels. Employees use the internal Solaria platform, which provides a growing number of AI applications in a secure environment that complies with privacy and data protection regulations. They also have access to PairD, an internal chatbot based on OpenAI’s latest language model.

Externally, Deloitte can now help clients implement trustworthy AI solutions at scale thanks to its strategic alliance with Anthropic, the company behind the Claude AI system. The company has developed a systematic approach that enables AI projects to move beyond the testing phase and be rolled out for broad, company-wide use while avoiding sprawl and minimising security risks. Thanks to a modular design with reusable components, ongoing team training and systematic process optimisation, this approach is enabling AI projects for clients to be put in place much more quickly and efficiently.

Deloitte Switzerland is also making targeted use of the Deloitte network, with its wide range of global delivery centres. One key element of this network is the innovation centre in Cairo, which houses 500 technology specialists. “Even in times of skilled labour shortages, it is crucial to be able to scale up quickly for major projects and offer our clients the required expertise without delay,” says Savoia.

Investing in people and society

Deloitte hired 405 new employees in the reporting year, with a particular focus on AI and digitalisation skills. It also continues to invest heavily in training and development, including at the Deloitte University in Paris.

Deloitte also grew its donation volume by 28 per cent to CHF 1.87 million in the past year, while voluntary work even increased by 44 per cent to over 12,900 hours. The company remains committed in terms of diversity, equality and inclusion and maintaining its support for key programmes.

Progress and challenges on the sustainability front

Sustainability remains a critical issue for Deloitte and its clients. Deloitte Switzerland currently employs 50 dedicated experts, who provide comprehensive support to companies as they implement their sustainability strategy. At the same time, Deloitte is pursuing some ambitious targets to achieve net-zero by 2040 and is playing a pioneering role within the industry in this regard. These objectives have been officially validated by the ‘Science Based Targets initiative’ (SBTi).

Its ‘Scope 3’ emissions, especially those generated by business travel, remain an important area of focus. Deloitte is actively helping its employees to reduce their environmental footprint. It has also stepped up its work with suppliers to systematically reduce emissions along the entire value chain.

Being awarded EcoVadis ‘Platinum’ medal puts Deloitte in the top one per cent of all companies that have been assessed and underlines the quality of Deloitte’s sustainability efforts in several areas: the environment, labor and human rights, ethics and sustainable procurement.

“We will continue to invest in all areas that are important to us: in our employees, in technology, in society and in the environment,” says Reto Savoia. “Our healthy business performance in a highly volatile environment, the hard work and dedication of our employees, the high level of satisfaction among our clients, and the investments we have made demonstrate that we are developing on a very sustainable and profitable footing.”
