How they work
Software Circle is an AIM-listed acquirer and operator of vertical-market software businesses in the UK and Ireland. Formerly Grafenia, it provides a permanent home for acquired businesses, which retain their names, teams and day-to-day operating autonomy. Its businesses serve markets including financial services, education, care, property, graphics and ecommerce.
Owners start by sharing a business summary or website link, followed by an introductory call about the business and its plans. Software Circle offers to sign an NDA before that discussion if requested. Acquisition proposals are reviewed against investment guardrails; exceptions require board approval.
