Investment thesis

Beltrae operates as both a corporate finance advisory firm and a private equity investor, with the two functions working in synergy. Rather than deploying capital through a formal fund, investment is provided directly by the Beltrae team, sometimes alongside partners. It backs acquisitions, sales, MBOs, buy-ins and private-equity cash-out deals across a broad range of sectors, with particular expertise in family-business exits. Current deal sizes range from £1M to £15M, and investment to date exceeds £60M. The firm also invests in property, originating and structuring deals and co-investing in projects across the British Isles, Continental and Eastern Europe, and the USA.
