OneAdvanced secures £1.2 billion refinancing to further accelerate growth and innovation

We are thrilled to announce the successful completion of a £1.2 billion private credit refinancing from existing debt, led by globally renowned lenders Ares Management Direct Lending funds , Carlyle, and Goldman Sachs Alternatives, a testament to our continued momentum, following a strategic shift to verticalise our SaaS portfolio, with our ‘Customer for Life’ ethos at heart.

Since joining in April 2023, our CEO, Simon Walsh, and the team have transformed the business, refining our sector-focused market segmentation, refreshing our product strategy, revising our operational foundations and reviving our culture.

We've achieved double digit ARR annual growth, with subscription revenues now accounting for over 88% of total revenues. In April, we were also named Europe’s Best Employer, 2025 by the FT.  

“This is a strong vote of confidence in our transformation journey, product roadmap, and future financial trajectory,” said Simon Walsh, CEO of OneAdvanced. “We are doubling down on AI-led innovation and customer value creation across the critical sectors we serve, powering the world of work.” 

Our recent platform investments, including security by design, embedded AI, multi-purpose APIs and WCAG 2.2 compliance accessibility, have allowed us to deliver on our promise of becoming the UK’s first sovereign AI service for business. Since April 2025, OneAdvanced AI is now empowering customers, helping them embed AI safely, securely, within their mission critical business workflows.

In July we continued our AI revolution by launching our first AI-Agents, reinforcing our responsible stance to the use of AI in mission-critical businesses and workflows, underpinned by the appropriate security, governance and compliance.

This has been further evidenced by the launch of our free resource hub, the OneAdvanced Trust Centre, helping security and privacy teams stay on top of the latest data, compliance, and security needs.   

In May 2025, we completed the first quarter of our new financial year with a 12% annualised ARR growth. Over 340 organisations adopted, expanded or modernised their software with OneAdvanced. These organisations included leading public and private sector brands such as, the Ministry of Justice (MoJ), Greater Manchester Mental Health NHS Foundation Trust, the University of Greenwich, Haribo, and Trenitalia.   

“We are pleased to collaborate with Carlyle and Goldman Sachs Alternatives to provide a highly bespoke and flexible financing solution at scale to support OneAdvanced in its next stage of strategic growth,” said Allan Nielsen, Partner at Ares. “Through its strong software capabilities and investment in innovation, as well as the backing of Vista and BC Partners, OneAdvanced has evolved into a leading UK vertical-specific SaaS provider. We look forward to being a part of this journey.” 

“We are delighted to support OneAdvanced’s future growth,” said Taj Sidhu, Head of European and Asian Private Credit at Carlyle. “As a leading provider of mission-critical software solutions to a diverse and growing customer base, OneAdvanced enjoys a strong competitive position in a market benefitting from secular trends. We look forward to partnering with the OneAdvanced management team, alongside Ares and GSAM, and with the support of financial sponsors Vista and BC Partners.”    

“We are excited to partner with Vista, BC Partners and OneAdvanced’s management team alongside Ares and Carlyle to boost the Company’s future growth,” said Moritz Jobke, Head of Hybrid Capital for EMEA at Goldman Sachs Alternatives. “OneAdvanced is a market-leading ERP software provider in the UK, with strong innovation capabilities and significant growth potential. Providing complex and bespoke financing solutions to industry leaders is core to our Hybrid Capital strategy, and we look forward to being part of OneAdvanced’s growth journey.”  

Existing investors, BC Partners and Vista Equity Partners, have supported us throughout this journey, reinforcing their belief in our strategy, impact and growth. 

The increased commitment by existing investors significantly strengthens our financial position, enabling us to accelerate our growth and impact.  

We extend our gratitude to everyone involved in achieving this success. Together, we are powering the world and future of work in the UK.
