Adhesion Wealth Advisor Solutions

What Adhesion Wealth Advisor Solutions does

Adhesion Wealth Advisor Solutions, Inc. is a Charlotte, North Carolina-based provider of unified managed account (UMA) administration and investment management infrastructure for independent registered investment advisors (RIAs), asset managers, and Turnkey Asset Management Platforms (TAMPs). Founded in 1999 and operating since December 2022 as a wholly-owned subsidiary of AssetMark Financial Holdings, Inc. (NYSE: AMK), the company powers over 2,800 fee-based advisors across approximately 180 RIAs. Its core product is an advisor-driven UMA platform that delivers outsourced trading, overlay portfolio management (monitoring, restrictions, cash management, trading and rebalancing), multi-custodial integration, and tax management services, supported by proprietary direct-indexing capabilities and a tax-loss harvesting product that has demonstrated 51.59 basis points of value delivered.

The platform architecture consists of modular components including the Adhesion Manager eXchange (AMX), the industry's second-largest model marketplace connecting advisors to over 300 asset managers and 1,800+ models, the Advisor Desktop for performance reporting and proposal generation, and Personal/Direct Indexes for customizable tax-managed equity strategies. Recent 2026 product enhancements include zero-fee ready-to-use model portfolios (Adhesion Essentials), enhanced daily Tax Management Services, and expanded access to private markets. The technology stack integrates with custodians, reporting partners, and the Addepar portfolio analytics platform; uses Okta for SSO across advisor and manager portals; and operates as a multi-custodial solution compatible with the custodian relationships advisors already maintain.

Adhesion's business model rests on three primary revenue streams: recurring platform/technology fees on UMA accounts (with select Essentials accounts exempt), model marketplace access and pass-through model manager fees, and tax optimization / Tax Alpha services. The company operates a sales-led GTM targeting RIAs (particularly those changing platforms, re-thinking outsourcing, or seeking independence), augmented by channel partnerships (notably TradePMR's Fusion platform) and technology integrations (Addepar, WealthShield for OCIO+). Distribution is national within the United States, anchored by Charlotte and with strategic alignment to AssetMark's Concord, CA headquarters. The company has won the WealthManagement.com Industry Award for Model Marketplaces four consecutive years (2019-2022) and the 2024 MMI/Barron's Digital Innovation award.
