## About

Mariner Platform Solutions was established as the institutional backbone for advisors affiliated with or acquired by Mariner Wealth Advisors, the national registered investment advisor founded by Marty Bicknell that has grown through an aggressive roll-up strategy. The platform provides a curated suite of investment strategies, model portfolios, and operational infrastructure — including billing, reporting, and compliance — that allows financial advisors to integrate quickly without building their own back-office from scratch. The wealth-origin narrative ties directly to Bicknell, who launched the parent firm in 2006 after a career at large broker-dealers and has since scaled it into one of the country's largest independent RIAs. The platform's deployment architecture spans traditional asset allocation models, third-party manager due diligence, and technology integrations that feed into the unified client experience Mariner brands nationally. Advisors on the platform gain access to centrally managed portfolio strategies, manager research, and a unified custodial relationship framework, all while retaining local client relationships. The geographic footprint follows Mariner's office map — concentrated in the Midwest and Plains states initially, with growing density in the Sun Belt and Northeast as the RIA consolidates practices in those markets. The model competes functionally with platforms like Dynasty Financial Partners and Hightower, though Mariner Platform Solutions is structurally embedded within an acquiring RIA parent rather than operating as a pure outsourced services provider. The Mariner enterprise reported managing approximately $120 billion in assets as of 2024, though Mariner Platform Solutions itself does not report a standalone AUM or deployment figure. The parent firm houses over 2,000 professionals across more than 90 offices nationally, with platform services staff augmented by specialists in investment research, technology, and practice management consulting. Adjacent vehicles include the Mariner Wealth Advisors RIA parent and Mariner Institutional, which serve distinct client segments. A significant adjacent capability is Mariner's tax and estate planning arm, which feeds directly into the holistic advice model the platform supports. In early 2024, Mariner announced a strategic investment from a consortium of institutional investors including Neuberger Berman to fuel continued acquisitions and platform development (per the firm, January 2024). The structural differentiator is Mariner Platform Solutions' role as a captive acquisition-integration engine: whereas most TAMPs court independent advisors with no ownership linkage, Mariner's platform is designed to accelerate the operational assimilation of acquired practices into the parent RIA's standardized investment and service architecture. Newly acquired advisors migrate onto the platform's investment models, billing systems, and compliance framework within months of closing, creating a repeatable integration motion that fuels Mariner's M&A-driven growth. The parent firm's hybrid capital structure — private equity backing alongside advisor equity — also gives the platform a funding tolerance unusual among RIA-owned platform services units.

## Questions

### Is Mariner Platform Solutions available to advisors outside the Mariner Wealth Advisors network?

Mariner Platform Solutions primarily serves advisors who are part of the Mariner Wealth Advisors RIA, either as legacy employees or through acquisition. The firm has historically not marketed the platform as a standalone service to fully independent RIAs in the way that Dynasty Financial Partners or Goldman Sachs Custody Solutions does. Its primary function is operational integration and investment delivery within the Mariner parent structure.

### How does the platform handle compliance and regulatory oversight?

Mariner Platform Solutions integrates directly with the parent RIA's compliance framework, operating under Mariner Wealth Advisors' SEC registration as a registered investment adviser. Advisors on the platform benefit from centralized compliance reviews, trade surveillance, and marketing material approvals that satisfy RIA regulatory obligations, reducing the need for each practice to maintain standalone compliance infrastructure.
