## About

Adviser Investments was founded in 1994 by Daniel P. Wiener, who had earlier launched the Independent Adviser for Vanguard Investors newsletter. The newsletter's analytical rigor formed the client-acquisition engine for what became a registered investment adviser, converting readers into managed-account relationships over nearly three decades. The firm has always been tightly associated with Vanguard and actively managed mutual funds, a posture that distinguished it from the passive-indexing wave that swept the RIA industry. The firm constructs portfolios primarily from actively managed mutual funds and ETFs, with a particular emphasis on Vanguard, Dodge & Cox, Primecap, and other managers Wiener's research team has tracked for decades. Client accounts are typically model-driven separately managed portfolios allocated across US and international equity, fixed income, and balanced strategies. Adviser Investments does not originate direct private deals or operate a venture arm; its investment exposure is almost entirely public-markets. The geographic focus is US-centric, though the firm has historically recommended international equity funds managed by US-based firms. In January 2022, the firm announced that Mario Ramos had succeeded Wiener as CEO, with Wiener remaining chairman. The transition was a planned leadership change after Ramos's tenure as president. The firm operates from its headquarters in Newton, Massachusetts, and has served thousands of individual and institutional clients. While no audited headcount is publicly disclosed, the adviser's ADV filings historically reflected a team of roughly 50 to 80 professionals. What sets Adviser Investments apart is its lineage as a newsletter-first advisory business — a model that few firms have sustained at scale. The research-to-advice pipeline, built on editorial trust rather than a traditional broker-referral network, gave the firm a direct relationship with a self-selected audience of diligent fund investors. This allowed the firm to scale without the intermediary costs embedded in most wealth-management distribution models.

## Questions

### Who runs investment decisions at Adviser Investments?

Daniel P. Wiener, the founder and chairman, has historically guided the investment philosophy, but the firm employs a dedicated investment committee and research team. The daily portfolio management and manager-selection decisions are executed by the firm's investment professionals, with oversight from the committee. The firm's public communications emphasize a team-based approach rooted in Wiener's original mutual-fund research methodology. Specific personnel names beyond Wiener and CEO Mario Ramos are not widely cited in public disclosures.

### What is the firm's relationship with Vanguard?

Adviser Investments is not affiliated with Vanguard. The relationship stems from founder Daniel Wiener's newsletter, the Independent Adviser for Vanguard Investors, which covered Vanguard funds extensively. The firm built its early client base from those newsletter subscribers, and Vanguard funds have historically represented a significant allocation in client portfolios. This deep analytical coverage of Vanguard's active funds became a specialization that differentiated the firm in the RIA space.

### What is the minimum account size?

Specific minimums are not publicly listed in a durable, citable source. Typical RIA firms of this scale often require $500,000 to $1 million in investable assets for full wealth-management relationships. Direct inquiry with the firm is the only way to confirm current account-size thresholds.

### What asset classes does the firm avoid?

The firm has no known direct-investment practice in private equity, venture capital, hedge funds, or real estate. Its public disclosures and editorial lineage have centered almost exclusively on public-market mutual funds, ETFs, and separately managed accounts. Alternative investments do not appear in its core strategy descriptions.
