The Ontario Municipal Employees’ Retirement System is reinvesting in a U.K.-based online mental health-care company.

The OMERS participated in a funding round that raised £20 million (about $33 million) for HelloSelf, which connects patients with psychologists and therapists through an online platform. In 2021, the OMERS invested £5.5 million (about $9.1 million) and served as the lead investor during HelloSelf’s first funding round.

The company, which was founded in 2018, uses artificial intelligence technology and works with 160 mental-health professionals. The AI systems are also used to automatically make notes and set reminders for patient and clinicians.
