"Zenith will provide an additional touch point for our internal team and will assist in the formation of our approved investment lists and research services and solutions distributed to advisers," ThreeSixty Research head Lisa Boyce said.
"Our model is based on leveraging quality external research and complementing this with our strong internal research capability.
"This enables us to focus our in-house research efforts on specialised research services, such as portfolio construction guidance across both equities and managed funds and investment communications."
