25 Financial vs. Major RIA Aggregators: A Comprehensive Comparison
Key Takeaways
- Aggregators centralize platforms and operations; boutique fiduciaries emphasize customization and direct advisor relationships.
- Alternative investments (private equity, private credit, real estate) are now mainstream, but access and minimums vary by firm and investor qualification.
- Minimums and fees differ widely across firms; always verify the firm’s Form ADV and current disclosures before making decisions.
What Is an RIA Aggregator?
An RIA aggregator acquires or affiliates with independent advisory firms to create scaled platforms, centralizing compliance, technology, investment research, and back office while varying the autonomy of local teams. Models range from integrators (full centralization) to pure aggregators (more autonomy) and hybrids.
Boutique Fiduciary vs. Aggregator: Core Differences
- Advice model: Boutique firms prioritize fiduciary‑first, product‑neutral advice; aggregators often leverage firm‑level models or research teams.
- Personalization: Boutique firms typically design tailored strategies for complex goals (e.g., business owners, concentrated positions, multi‑entity tax planning). Aggregators deliver consistency and efficiency via standardized portfolios with customization bands.
- Access to alternatives: Availability and minimums differ; many firms now offer curated private market access to qualified investors, but program scope and vehicles vary.
Access to Alternatives: Private Equity, Private Credit, Real Estate
Today’s reality: Alternatives are a core allocation for many advisors, with growing use of evergreen vehicles and platform technology. Suitability and accreditation still apply.
What to ask:
- Minimums & qualifications (accredited investor status, vehicle structure).
- Due diligence process (committee review, third‑party diligence, reporting).
- Fees & liquidity (carry/performance fees, lock‑ups, K‑1 timing).
Fees & Minimums: What Investors Actually Pay
Fisher Investments: Many independent reviews note $1M typical minimum; some cite $500k for private clients, with tiered AUM fees roughly 1.00%–1.50%, varying by strategy and balance. Always confirm directly with Fisher.
Mercer Advisors: Reviews indicate tiered AUM fees ~0.5%–1.1% and varying minimums by service; firm‑level details may differ. Check Mercer’s current disclosures.
Mariner Wealth Advisors: No firm‑wide minimum; a quarterly minimum fee may apply for smaller balances. AUM fees ~0.60%–1.25% on the first $1M.

- Confirm fiduciary & conflicts (fee‑only, product neutrality).
- Compare planning depth (tax, estate, charitable integration).
- Assess alternatives access (qualification, minimums, diligence process).
- Validate fees & minimums in the firm’s ADV Part 2A and current disclosures; don’t rely solely on reviews.
