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.

Sector focus
B2B vertical-market software for specialised customer groups, particularly mission-critical systems embedded in regulated or specialist workflows.
Geography
United Kingdom and Ireland.
Ownership
Decentralised ownership: acquired businesses retain their names, teams and operating identities, with capital and support from the group.
Majority or minority
Whole-company acquisitions: the 2026 report lists wholly owned subsidiaries and records purchases of the entire share capital of its two latest acquisitions.
Target ARR
At least £500,000 of recurring revenue per annum, with a majority of revenue recurring, under the 2026 acquisition guardrails.
Target EBITDA
Historically profitable, with stable or growing adjusted EBITDA over the previous three years; no minimum EBITDA amount is stated.
Enterprise value
Valuation multiple up to 7× adjusted EBITDA under the 2026 acquisition guardrails; no absolute enterprise-value range is stated.
Capital model
AIM-listed operating group that reinvests cash generated by its businesses and uses debt to finance acquisitions.
Hold period
Permanent ownership: its stated model is to acquire and retain businesses rather than sell them.
Founder ownership
Seeks founder-led software businesses; its permanent-home model retains each business’s identity and operating autonomy.
