Trillium Asset Management

What Trillium Asset Management does

Trillium Asset Management, LLC is a Boston-headquartered, privately held investment management firm founded in 1982 by Joan Bavaria (originally as Franklin Research & Development), making it one of the oldest dedicated socially responsible investing (SRI) advisors in the United States. The firm offers seven ESG-integrated investment strategies across equity (Global Equity, Core Equity, Large Cap Core, Small/Mid Cap Core, Growth & Income, Sustainable Opportunities) and fixed income (US Core Bond), supplemented by two mutual funds (Trillium ESG Global Equity Fund and Trillium ESG Small/Mid Cap Fund) and a Community Impact Investing module that directs capital to community development banks, credit unions, and non-profit loan funds.

The firm's investment process is built on a proprietary ESG scoring methodology that integrates material quantitative and qualitative ESG data with fundamental financial analysis. Trillium maintains a dedicated shareholder advocacy team that conducts active ownership engagements (260+ cumulative) to drive ESG outcomes at portfolio companies. The firm employs approximately 60 team members across investments, advocacy, operations, compliance, and business development, with offices in Boston and San Francisco. As of March 31, 2026, Trillium reports $3.93 billion in AUM, $1.0 billion in model assets, and $4.98 billion in total assets under advisement.

Trillium generates revenue primarily through management fees charged as a percentage of assets under management, with pricing not publicly disclosed and likely negotiated by strategy, account size, and client type. The firm serves three primary client segments — Private Clients (individuals, family offices, non-profits), Financial Intermediaries (financial advisors and wealth managers), and Institutional Investors (consultants, pension funds, endowments, foundations) — through a relationship-based, sales-led GTM supported by content marketing, conference participation, and thought leadership. The firm was acquired by Australian financial services company Perpetual Ltd in 2020 and operates as a certified B Corporation (since 2008) and UNPRI signatory (since 2007).
