Independent registered investment advisors are gaining scale, but competing with large broker-dealers increasingly requires more than portfolio-management technology. RIAs also need access to banking, lending, cash-management and other financial capabilities traditionally associated with larger wealth-management institutions. Aquiline is betting on that opportunity with an agreement to acquire a controlling interest in Flourish, the wealthtech platform currently owned by MassMutual.

The independent financial-advisor market is becoming an increasingly important battleground for wealthtech companies and financial-services investors.

As RIAs compete with wirehouses and large broker-dealers, the technology gap is no longer limited to portfolio management or client reporting. Independent firms increasingly need infrastructure that can help them address more of a client’s financial life—including cash management, lending and other services traditionally delivered through banks.

That is the market Aquiline is targeting with its planned investment in Flourish.

The private-equity firm announced a definitive agreement to acquire a controlling interest in the New York-based wealthtech platform from MassMutual, which will retain a significant stake. The transaction is expected to close in the fourth quarter of 2026, subject to regulatory approvals and customary closing conditions.

Flourish currently serves more than 1,300 registered investment advisors, according to the companies. Its advisor-led cash-management business has grown assets under custody from $1 billion to $8 billion in five years, while the company has recently expanded beyond cash management into lending.

That expansion is central to the investment thesis.

Flourish recently introduced what it describes as a home-lending solution designed specifically for the independent advisor channel. The move reflects a broader shift in wealth management: advisors increasingly want to participate in financial decisions that extend beyond investment portfolios.

For an RIA, a client may hold a substantial investment portfolio but also maintain cash at a bank, finance a home through another institution and obtain other lending products elsewhere. The advisor may understand the client’s overall financial position, but the economics and technology infrastructure of those relationships often sit outside the advisory firm.

Flourish’s strategy is to bring more of those financial relationships into the advisor’s orbit.

That is a different proposition from simply adding another portfolio-management application to an RIA technology stack.

Cash management and lending can create recurring points of engagement between advisors and clients, particularly around major financial decisions. They can also give independent firms additional ways to deepen relationships without becoming traditional banks themselves.

The model is arriving as the RIA sector continues to gain influence.

Cerulli Associates reported in 2026 that independent and hybrid RIAs increased their combined share of industry assets from 21% in 2014 to 27% in 2024, while their assets under management grew at annualized rates of 10.9% and 12.2%, respectively.

That growth is creating a larger technology market around independent advisors.

The competitive pressure is not just coming from traditional wealth managers. Large independent broker-dealers, custodians, turnkey asset-management platforms and specialist fintech providers are all building infrastructure designed to help advisors operate independently while retaining institutional-grade capabilities.

McKinsey has previously identified serving RIAs as a significant opportunity for wealth-management providers, noting that technology and third-party services have lowered barriers for advisors to establish independent practices. More recently, the firm has pointed to advisor-centric platforms and unified technology stacks as important components of the industry’s next phase.

Aquiline’s investment therefore gives Flourish access to a financial-services investor with experience across wealth, retirement and investment technology. The firm cited previous investments including Ascensus, AssetMark, RIA-in-a-Box and Sageview as part of its wealth-management track record.

The deal also brings an experienced wealth-management executive into Flourish’s leadership structure. David Canter, who previously led Fidelity’s RIA and Family Office segments, will become Flourish’s executive chairman.

For MassMutual, retaining a significant ownership position is notable. Rather than exiting completely, the insurer is effectively bringing in a new controlling investor while maintaining an economic interest in Flourish’s future growth.

That structure could give Flourish more room to pursue acquisitions, expand its product roadmap or invest in technology while preserving its relationship with MassMutual.

The competitive landscape remains crowded, however.

Platforms such as Charles Schwab, Fidelity, Envestnet and AssetMark already provide independent advisors with combinations of custody, technology, investment products and practice-management capabilities. Banks and fintech companies are also pushing financial products deeper into digital wealth-management workflows.

Flourish’s differentiation is its focus on areas where the traditional advisor relationship often ends: cash and lending.

That strategy could become increasingly valuable as RIAs seek to move from being investment managers to becoming broader financial relationships for their clients.

There is also a technology implication.

Wealthtech platforms are increasingly becoming integration layers between advisors and financial products. Rather than forcing an RIA to build banking, lending or cash-management capabilities internally, specialized providers can supply those services through technology and operational infrastructure.

That is consistent with a broader direction in financial technology: financial products are increasingly being embedded into existing customer relationships rather than sold as isolated products.

For enterprise wealth-management teams, the challenge will be making those services feel like part of a coherent advisory experience. Adding lending or cash products is relatively straightforward compared with integrating account data, compliance workflows, suitability processes, reporting and client communications around them.

Flourish’s next phase will therefore be judged not simply by how many products it adds, but by whether it can make those products useful to advisors without increasing operational complexity.

Aquiline’s investment gives the company additional capital and an owner experienced in scaling financial-technology businesses. MassMutual’s continued stake provides continuity.

The larger strategic bet is clear: the independent advisor market may increasingly compete on how much of a client’s financial life an RIA can serve, not just how well it manages an investment portfolio.

If that thesis holds, cash management and lending could become foundational components of the next generation of RIA technology platforms.

Market Landscape

The RIA wealthtech market is moving toward broader platforms rather than isolated point solutions.

Several forces are converging:

• RIA consolidation: Larger independent firms are seeking scale, technology and operational efficiency.
• Advisor independence: Advisors continue moving away from traditional captive models toward RIA and hybrid structures.
• Comprehensive advice: Clients increasingly expect advisors to address financial needs beyond investments.
• Embedded financial services: Cash, lending and banking capabilities are increasingly being integrated into wealth-management experiences.
• AI and automation: Wealth platforms are investing in technology to improve advisor productivity and client personalization.

Cerulli estimates that RIA assets have grown at approximately 11% annually over the past decade, while its 2026 research says the RIA market is approaching a new phase of consolidation and could eclipse $4 trillion over the next decade.

That growth is attracting both private capital and technology providers.

For RIAs, the strategic question is increasingly whether they can deliver a wirehouse-quality client experience without becoming a wirehouse. Platforms such as Flourish are attempting to provide pieces of that infrastructure while allowing the advisor to retain the client relationship.
