Impact Community Capital (ICC) was founded and is owned by a consortium of insurance companies that jointly invested as a closed group in low-income and affordable community development. ICC reached out to Tideline to help develop a business strategy and operating plan to open their impact investing services to new and varied institutional clients and expand ICC’s unique impact investing offerings. Tideline analyzed ICC’s investment history both to identify their best performing investments and to evaluate the potential fee revenue of those investments. Tideline also researched the market to identify the best future investment offerings and target investors for ICC. This analysis resulted in a comprehensive recommendation for business and product strategy. To facilitate the implementation, Tideline took the insurance company owners through a redesign of their ICC governance structure. Over the subsequent six-year period, Tideline was engaged to assist in the execution of various aspects of the strategy’s implementation.
