Rockpool is a fund manager that invests in private companies. It seeks out profitable and growing businesses which offer great value without the risk levels of start-ups. A company must have a proven business model, an experienced management team and annual revenues of £5m-£30m. Not large enough to attract traditional private equity funds or strategic buyers, these transformer companies are ready to embark on the journey to get there. They just need patient capital and some help to professionalise. Rockpool funds these through a mixture of equity and debt from their investors.
