Aaron Maeder

Aaron Maeder (also spelled Aaron Maeder) served as Geschaeftsfuehrer (Managing Director / CEO) of Ambassador Stiftung fuer die berufliche Vorsorge, an independent Swiss occupational pension fund (Pensionskasse) headquartered in Wittenbach / St. Gallen. He held this role with collective signature authority (Kollektivunterschrift zu zweien) until his departure, which was recorded in a Swiss commercial register mutation published on August 31, 2021, with an effective date of January 6, 2022. His successor as Geschaeftsfuehrer was Serge Baumgartner, who has since also departed the organization. The current deputy managing director is Stephan C. Frank.

Ambassador Stiftung was established by public deed on April 6, 1992, and operates as a registered, semi-autonomous collective foundation (registrierte, teilautonome Sammelstiftung) providing occupational pension plans within the Swiss BVG framework. The foundation serves approximately 6,400 active insured members across roughly 250 affiliated companies, with around 200 pension recipients. It is a member of the Ethos Foundation, indicating a commitment to sustainable and responsible investing. The foundation is also tracked by PitchBook as a limited partner, reflecting its allocations to venture capital and private equity funds.

Following his tenure at Ambassador Stiftung, Maeder's LinkedIn profile indicates he moved to a Geschaeftsfuehrer role at HHM Gruppe (HEFTI. HESS. MARTIGNONI.), a Swiss engineering and building technology firm with over 70 years of experience and approximately 220 employees across offices in Aarau, Basel, Bern, St. Gallen/Chur, Zug, and Zurich. Note: The source data listing him as an "Angel Investor" appears to be a misclassification -- his primary professional background is in institutional pension fund management and corporate leadership.

As Geschaeftsfuehrer of Ambassador Stiftung, Maeder oversaw a diversified institutional investment portfolio typical of Swiss pension funds operating under BVG regulations. Based on the most recent available data (2023), the fund's asset allocation was approximately:

The fund's investment approach prioritized:

The foundation has been tracked by PitchBook as a limited partner, indicating it makes commitments to external investment funds, including in the venture capital and private equity space.

• Swiss Equities: ~32%

• Real Estate: ~16%
• Alternative Investments: ~16% (including private equity and venture capital fund commitments)
• Cash / Liquidity: ~10%
• Maintaining a strong coverage ratio (116.75% as of December 31, 2024; 118.65% as of November 30, 2025)
• Generating stable long-term returns to fund pension obligations
• ESG-conscious investing as a member of the Ethos Foundation for sustainable development

• Role Misclassification: The source data listed Aaron Maeder as an "Angel Investor" with a "Seed Round" investment stage. This appears to be inaccurate. His professional background is in institutional pension fund management (Geschaeftsfuehrer of a BVG Sammelstiftung), not personal angel investing. Any investment activity through Ambassador Stiftung was institutional in nature as a pension fund LP.
• Current Affiliation: As of the most recent available data, Maeder appears to be affiliated with HHM Gruppe (HEFTI. HESS. MARTIGNONI.) in St. Gallen, an engineering firm rather than a financial institution.
