The Riverside Company has signed a definitive agreement to invest in Converge International, a provider of employee mental health and well-being services in Australia and New Zealand. On completion, Converge will join Altius Group Holdings, Riverside's corporate health platform. Altius provides employee health, well-being and occupational rehabilitation services in Australia.

Converge's services include employee assistance programs, critical incident support, onsite mental health services, training and consulting, and psychometric assessments. The company uses a B2B, employer-funded model. It serves more than 2,000 active clients through a network of more than 1,500 clinicians.

"The proposed investment addresses a key market opportunity in employee mental health services," said Ash Sorrenti, a principal at Riverside, in a statement. "Converge's established presence and high-quality clinician network across Australia and New Zealand, together with its relationships with major corporations will expand Altius' geographic reach and client base."

Riverside has completed more than 220 healthcare investments. Its Australian team has completed more than 30 healthcare transactions since it was set up in 2010. Managing partner Simon Feiglin and associate Hannah Davies worked with Sorrenti on the deal. Completion is subject to regulatory approvals.
