A spokesman for Mr. Angermayer, who has based his family office and other business ventures in Malta, did not respond to requests for comment.
In early 2021, Thiel Capital also became a shareholder in a Malta entity through a byzantine series of developments. The deal involved Coru, a Mexican online financial advice start-up, which has a parent company incorporated in London.
Entities controlled by Mr. Thiel and Mr. Danzeisen, his husband, were among Coru’s biggest owners, corporate filings show. The start-up needed additional funding in late 2020, but its investors could not reach an agreement to put more cash in, said two former investors. The company went into administration, the equivalent of bankruptcy.
Around that time, Mr. Thiel, Mr. Danzeisen and several other Coru investors established a company in Malta called EUM Holdings Melite Ltd., Maltese records show. That company bought Coru’s shares out of administration for about $100,000, according to British records. The records do not detail EUM’s business activities.
Now Coru is owned by EUM. Its shareholders include Mr. Thiel, Mr. Danzeisen, Richard Li — a son of Hong Kong’s richest man, Li Ka-shing — and a group with a former Nicaraguan government official and a scion of the Spanish family that made a fortune selling Lladró porcelain figurines.
Mr. Thiel began exploring Maltese citizenship around that time, said people familiar with the process. By late 2021, documents show, he was far along in the application process and retained an agency that fielded questions from the Maltese government about his businesses and political activities.
The questions included Mr. Thiel’s role with Palantir Technologies, a data analytics company he founded that works with governments and corporations, and his political activity supporting Mr. Trump.
