MassMutual to Acquire Fintech Platform Flourish

Platform delivers innovative product solutions and further enhances MassMutual’s digital strategy and talent

SPRINGFIELD, Mass.--()--Massachusetts Mutual Life Insurance Company (MassMutual) and Stone Ridge Asset Management (Stone Ridge), an asset manager with more than $10 billion in assets under management (AUM) that focuses on registered investment advisers (RIAs), institutions, and insurance companies, today announced that MassMutual and Stone Ridge Holdings Group have entered into a definitive agreement for MassMutual to acquire Flourish, a fintech platform for RIAs. Financial terms of the transaction are not being disclosed.

Flourish provides digitally enabled products and services to RIAs through various modules, including an established cash management offering, Flourish Cash. Flourish Cash is offered through Stone Ridge Securities LLC, Stone Ridge’s registered broker-dealer, which MassMutual will acquire pending regulatory approval. Flourish’s highly talented and experienced team is expected to join MassMutual as part of the transaction, which is anticipated to close in Q1 2021 pending necessary regulatory and other third-party approvals.

Today, Flourish services more than 350 RIAs representing more than $600 billion of AUM and is well positioned to seamlessly deliver additional, valuable services to RIAs and their clients. After the acquisition, Flourish will continue to serve RIAs, operating independently from MassMutual’s existing insurance and wealth management business. The team will focus on delivering the same industry-leading user experience it is known for, while leveraging MassMutual’s expertise and resources to expand the product offering and drive expansion.

“MassMutual is focused on providing a simplified, digital, customer-centric user experience, and Flourish will help accelerate that strategy, ultimately supporting our vision of providing financial well-being for all Americans,” said Gareth Ross, MassMutual Head of Enterprise Technology and Experience. “We are thrilled to have the exceptionally talented team from Flourish join MassMutual and add their digital expertise and track record of innovation to our efforts, and we look forward to delivering exciting new Flourish modules to advisors in the coming months.”

Flourish will expand MassMutual’s existing product suite and strengthen the company’s ability to deliver digitally enabled holistic financial planning while complementing its efforts to provide the best technology to its advisors and clients and deliver a seamless digital experience.
