Stonyfield Farm

The Stonyfield Farm family office shares its name and heritage with the organic yogurt company founded in 1983 by Samuel Kaymen and Gary Hirshberg on a New Hampshire farm. The office operates independently of the current operating entity, which Danone acquired full ownership of in 2016, and is led by principals who maintain the family's long-standing commitment to organic and sustainable investments. The investment strategy spans private equity, real estate, and agri-food ventures, with a focus on direct deals and co-investments alongside mission-aligned partners. Confirmed positions include real estate holdings in New York and Kansas, as well as investments in organic food and regenerative agriculture companies (per Bloomberg, 2024; per WSJ, 2023). The office targets opportunities across North America and Europe, with an emphasis on companies that align with the family's environmental and health-oriented values. The office maintains a small, lean team based in Leawood, Kansas, with additional presence in Bossier City, Louisiana; New York; Palo Alto; and Austin. In 2022, Stonyfield Organic (the operating company) achieved 100% renewable electricity for its New Hampshire manufacturing facility, reinforcing the family's commitment to sustainability beyond its investment portfolio. The office does not disclose AUM or total deployment. The Stonyfield Farm family office is a rare example of a wealth-holder that spun out of a successful consumer brand acquisition, maintaining a distinct identity from the operating company. Unlike many family offices that consolidate after a sale, this office retains a multi-generational investment focus with a clear mission-driven tilt toward organic and sustainable asset classes.

Frequently asked questions

Who runs investment decisions at Stonyfield Farm?

The office does not publicly name its investment principals. Given its small, lean team and low public profile, decision-making likely rests with a small group of family members and external advisors. No named CIO or managing partner is disclosed on the firm's website or in press coverage.

Is Stonyfield Farm structured as a single family office or does it operate more like a venture firm?

Stonyfield Farm functions as a single family office, managing the wealth generated from the 2016 sale of Stonyfield Organic to Danone. Unlike a venture firm, it does not raise external capital and maintains a low profile, with no public facing investment vehicles or series funds.

What investment stages does Stonyfield Farm typically target?

The office appears to focus on direct investments and co-investments, with a preference for later-stage or mature companies in the organic food, renewable energy, and real estate sectors. There is no public evidence of early-stage venture bets or seed-stage participation.

Which sectors does Stonyfield Farm explicitly avoid?

Based on the family's long-standing commitment to organic agriculture and environmental sustainability, the office likely avoids investments in conventional chemical agriculture, fossil fuels, and genetically modified organisms (GMOs). This posture is consistent with Stonyfield Organic's public mission and product positioning.

How is Stonyfield Farm related to the Stonyfield yogurt company?

Stonyfield Farm shares its name and founding heritage with the organic yogurt brand co-founded in 1983. The brand was sold to Danone in 2016, but the family office operates independently, likely managing the family's retained wealth from that sale. The office's investment strategy reflects the same environmental and health focus as the operating company.
