What Weatherbie Capital does
Weatherbie Capital, LLC is a Boston-based, private investment management firm founded in 1995 that specializes in actively managed small-cap growth equity investing. The firm operated as a sub-adviser managing the small-cap growth portion of the Liberty All-Star Growth Fund, Inc. (NYSE: ASG), a multi-managed closed-end investment company, with that mandate covering approximately $334-337.9 million in net assets during the management period. Weatherbie functions as a subsidiary or affiliated business unit within Alger, a 100% women-owned investment boutique, and its investment approach — including an ESG framework — is published on Alger's platform as a distinct sub-brand alongside Alger's large-cap, mid-cap, international, and alternative strategies.
The firm generates revenue through investment management fees on the assets it manages, a recurring subscription-style revenue model typical of asset managers. Its distribution channel is primarily institutional: it operates through the multi-manager structure of Liberty All-Star Growth Fund and through Alger's broader institutional distribution platform (mutual funds, ETFs, SMAs, UCITS, institutional separate accounts). Weatherbie's customer base, as documented in source data, is concentrated on a single institutional counterparty (Liberty All-Star Growth Fund, Inc.), with pricing not publicly disclosed.
Effective April 1, 2026, Congress Asset Management Company, LLP replaced Weatherbie Capital as the small-cap growth manager for Liberty All-Star Growth Fund, terminating Weatherbie's primary disclosed institutional mandate. The firm is led by President Matthew A. Weatherbie, with Joshua D. Bennett as Chief Operating Officer and Senior Portfolio Manager, Elizabeth A. Flanders as Chief Compliance Officer, Cynthia A. O'Neil as Senior Vice President of Administration and Corporate Operations, and Alan C. Kirby as Principal and Director of Investment Products. No technology products, APIs, data products, or proprietary software offerings are disclosed for the firm beyond its investment management services.

Weatherbie Capital competitors and assessment
Company assessmentDirect peers
- Congress Asset Management Company: Replaced Weatherbie as the small-cap growth manager for Liberty All-Star Growth Fund effective April 1, 2026. Direct competitor in the same sub-advisory mandate and small-cap growth category.
- Alger: Parent platform and direct sister firm. Alger offers small/SMid-cap strategies and is the corporate parent of Weatherbie Capital, making it the most operationally and strategically comparable entity.
- Wasatch Global Investors: Boutique active manager specializing in small- and micro-cap growth equities with a fundamental, bottom-up process. Closely comparable to Weatherbie's investment style and boutique positioning.
- Granahan Investment Management: Specialist small-cap and SMID-cap growth equity boutique managing concentrated, actively selected portfolios — directly analogous to Weatherbie's value proposition.
- Royce Investment Partners: Long-standing small-cap equity specialist with multiple small-cap growth and value strategies; competes for the same institutional sub-advisory and SMA mandates.
- Calvert Research and Management: Active equity manager known for ESG-integrated strategies across small- and mid-cap segments; closely comparable to Weatherbie's ESG-credentialed small-cap growth approach.
Broad incumbents
- T. Rowe Price (Small-Cap Growth): Established incumbent with a flagship Small-Cap Growth fund and broader institutional offerings; a dominant competitor for the same institutional mandates Weatherbie targets.
- William Blair Investment Management: Larger active equity manager with dedicated small-cap growth strategies; broader product platform but overlapping institutional client base and investment process.
- Loomis Sayles (Small-Cap Growth): Large multi-affiliate active manager with small-cap growth strategies; comparable institutional client base and multi-manager/closed-end fund relationships.
Emerging players
- Trillium Asset Management: ESG/sustainable-focused boutique with active public equity strategies including small-cap exposure. Comparable on the ESG dimension though broader in mandate scope.
