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.

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.
