The agency has been brought on board to lead the firm's financial PR, investor relations, corporate, trade and consumer communications.
The appointment was made as AIM-listed Ultrasis embarks on a major rollout of its flagship product designed to treat anxiety and depression, Beating the Blues, to a wider audience.
Beating the Blues is an eight-week, web-based treatment programme for depression based on Cognitive Behavioural Therapy.
The account will be headed up by JBP director Karen White. Financial communications will be handled by the JBP's investor relations division Performance Communications.
