Daniel Hemmeler

Daniel Hemmeler is a Swiss banking executive associated with Banque Thaler SA, a Geneva-based private bank founded in 1982 that specialized in wealth management for families and entrepreneurs using a "family office" approach. According to the Swiss Commercial Register (FOSC/SHAB), Hemmeler was a member of the bank's general management and was appointed director with collective signature authority for two, a change recorded in a 2014 register publication. He is originally from Aarau and is resident in Sion, in the canton of Valais.

Beyond his banking role, Hemmeler holds foundation governance positions in Valais. Public register records list him with Le Glarier Résidence Médicalisée, a Sion-based foundation operating a medicalized nursing residence (registered in 1991), where he moved from vice-president of the foundation council to president of the foundation council, again with collective signature for two. This reflects a profile typical of a senior Swiss private banker who also sits on regional charitable/institutional boards.

An important status change: Banque Thaler SA was acquired by CA Indosuez (Switzerland) SA (part of Crédit Agricole's wealth-management arm) — the acquisition closed around 1 September 2025 and Banque Thaler was absorbed by merger on 15 December 2025, ceasing to exist as a separate legal entity. Its client activities now continue under the Indosuez Wealth Management brand from Quai Général-Guisan in Geneva. As a result, the banquethaler.ch domain and email addresses redirect to / are administered by the CA Indosuez organization.

• No public evidence was found of Daniel Hemmeler operating as a startup angel investor, of any seed-stage checks, sector focus, or named portfolio companies. The "Angel Investors / Seed Round" designation in the source stub could not be verified against any primary source and should be treated as unconfirmed.
• His verifiable professional activity is private banking / wealth management at Banque Thaler (now CA Indosuez), where the institutional focus was on managing wealth for families and entrepreneurs.
• If he does make private/angel investments, it would most plausibly be as an individual through the private-banking/family-office channel typical of Geneva wealth managers — but this is inference, not a sourced fact.
