Diana Capital UK

Diana Capital UK was established in 2015. Dr. Claus S. Hass serves as Managing Director and also holds a partnership at the law firm Hass Dross Theiss. The firm invests on behalf of a European industrial family whose wealth stems from industrial operations. The strategy centers on commitments to private equity funds. Geographic coverage spans the US, Europe and South East Asia, including China. Investment types include buyouts and venture capital alongside fund-of-funds structures. Confirmed holdings and co-investors are not publicly detailed beyond the regional fund focus. The firm operates from a single office in central London. No additional offices or adjacent vehicles such as foundations appear in public records. Alexander Robert Fellowes and Alexandra Flick-Butz are listed as persons with significant control in UK filings. No operational events from the last 24 months are recorded. The structure links to a German affiliate, Diana Capital GmbH, also under Dr. Hass. This cross-border setup coordinates investment decisions between the UK and German entities for the same family principal.
