About Felix Haldner
Felix Haldner is a Swiss finance executive with more than three decades in private markets, financial services and industry governance. He studied law at the University of St. Gallen. Before joining Partners Group in 2001, he was a partner at PwC, where he advised asset managers and insurers on M&A and tax planning.
At Partners Group he was a partner and Executive Board member and headed the Investment Structures department. There he structured private markets client programmes and worked on acquisitions and investment sales. Partners Group later said he would focus on strategic client development in Europe. He later served as president of the Swiss Funds & Asset Management Association (SFAMA), also referred to as the Asset Management Association Switzerland (AMAS).
He now holds board roles. Tenity, a fintech venture platform, appointed him to its Board of Directors. He is also a board member of the materials company noriware and, per Crunchbase, of the thermal sensor company GreenTEG (listed from December 2022).
Public records show one angel investment: Aisot Technologies, in August 2026. Crunchbase lists him as an individual investor with one portfolio company. No other angel investments with dates were found in public sources, so none are listed here.
Haldner joined Aisot Technologies' seed extension, announced on 13 August 2026. The round was CHF 2 million, reported as €2.13 million. It was backed by existing investors, family offices and experienced angel investors, and Haldner joined as a new investor.
In the announcement he said he was convinced Aisot's solutions can generate significant efficiency gains for asset and wealth managers, including in analysis, portfolio management and product development. He also said the company's models deliver signals across different investment strategies.
The only public data point on his investing is Aisot, a Zurich-based seed-stage company that sells AI tools to institutional investors. His own background is in private markets and asset management. In the Tenity announcement he said AI and digital assets are reshaping global markets now. Typical check size, stage preferences and geographic focus beyond this are not public.
