History

The company was founded by Vin Murria in 2008. Originally listed on the Alternative Investment Market in 2008 with a cash value of £3 million, it was bought by Vista Equity Partners in 2014 for £765 million. From the 18% stake Murria held in she took £140.2m from the sale making her one of the wealthiest women in the UK.^[1] Murria was awarded an OBE for services to the UK digital economy and advancing women in the software sector in the 2018 New Year Honours.^[2]

At the time of sale, Vista brought in a new leadership team including Chief Executive Officer Gordon Wilson, and Chief Financial Officer Andrew Hicks.

In August 2019, Vista sold a 50% stake to BC Partners for £2 billion including debt.^[3]

In 2023, the company undertook a strategy refresh, alongside changes to the executive management team, appointing Simon Walsh as Chief Executive Officer, Stephen Dews as Chief Financial Officer and Andrew Henderson as Chief Technology Officer. The aim of the strategy refresh was stated to prioritise resources into high growth market sectors and product categories.^[4] Part of this refresh, which cost £8.2m,^[5] included updating the operating name from "Advanced" to "OneAdvanced".

In August 2022, the company experienced a cybersecurity incident caused by LockBit 3.0 ransomware.^[6] Adastra, Caresys, Odyssey, Carenotes, Crosscare, Staffplan and eFinancials products were all affected, with downtime and recovery lasting for several months.

Perpetrators of the attack were able to extract information relating to 16 Staffplan and Caresys customers.^[7] 82,946 people were affected by the breach which included phone numbers and medical records, as well as details of how to gain entry to the homes of 890 people who were receiving care at home. ^[8]

The cyber attack including resulting remediation and outage credits cost the group £18.2 million in 2023^[4] and £9.4 million in 2024.^[5]

The Information Commissioner's Office announced in August 2024 a provisional decision to impose a fine of £6.09m on the company, following an initial finding that the provider failed to implement measures to protect the personal information.^[8] The ICO and OneAdvanced agreed a voluntary settlement in March 2025.^[9] OneAdvanced agreed to pay a final penalty of  £3,076,320 without appealing. The final investigation found that personal information belonging to 79,404 people was taken, including details of how to gain entry into the homes of 890 people who were receiving care at home.
