Sam Jeffries runs Sarasin & Partners' asset management team, which oversees £16.3bn.

Sarasin & Partners

Sarasin & Partners was founded in London in 1983 as Sarasin Investment Management, a specialist asset manager with roots in the Swiss private banking group J. Safra Sarasin. It converted to a limited liability partnership in 2007, and today the London management team holds a 40% voting stake, with Bank J. Safra Sarasin owning the remainder. This independent partnership model has underpinned a client base spanning private clients, charities, pension funds, and institutions, with a particular institutional concentration in the UK charity sector. The firm operates as a global thematic investor with a responsible approach to stewardship. Its core asset-class coverage spans global equity, multi-asset, fixed income, and listed real estate, accessed through segregated discretionary mandates, Charity Authorised Investment Funds (CAIFs), and a Model Portfolio Service for intermediaries. In 2022, it acquired Sarasin Bread Street to build a dedicated private markets capability — a signal of push into private equity and specialist private-market opportunities alongside its existing listed-market strategies. The firm's stewardship pivot is operationally thick: Natasha Landell-Mills leads the team, which votes, engages companies on climate, and advocates for audit reform. In 2025, the firm launched a Shariah Investment Service, extending its multi-asset product line into values-based mandates. Sarasin & Partners does not publish a public headcount, but the team visible on its website indicates a deep bench of over 50 investment professionals spanning portfolio management, equity analysis, stewardship, and private markets — with additional sales and intermediary distribution. The firm operates through the London headquarters and a subsidiary, Sarasin Asset Management, CEO'd by Jamie Black, which specializes in US clients. Adjacent vehicles include the specialist private-markets unit Sarasin Bread Street, led by Alex Barr, and a tightly integrated stewardship operation that co-authors the Sarasin Compendium of Investment. In September 2025, Jamie Black transitioned out of the Head of Private Client role, reflecting a leadership handover within the firm's largest legacy department. The structural differentiator is the firm's dual identity: an independent partnership with significant management ownership, yet part of the J. Safra Sarasin capital and distribution orbit. This allows Sarasin & Partners to operate a boutique governance model with access to the group's global thematic research framework, while its concentrated stewardship mandate — blending active ownership, policy advocacy, and a thematic equity engine — separates it from generalist multi-asset managers that lack a deep charity-sector franchise.

Frequently asked questions

Who runs investment decisions at Sarasin & Partners?

Investment leadership is split by function. Sam Jeffries heads the Asset Management team with ultimate responsibility for investment performance. Phill Collins serves as Chief Investment Officer of multi-asset, overseeing the multi-asset team, while Alex Barr leads private markets through Sarasin Bread Street. The firm's Investment Policy Committee co-authors the central asset allocation guidance.

How is Sarasin & Partners related to Bank J. Safra Sarasin?

Sarasin & Partners was originally formed in 1983 from the J. Safra Sarasin private banking group. Today it operates as a limited liability partnership owned partly by its London management (40% voting rights) and partly by Bank J. Safra Sarasin (the remainder). This structure grants the firm operational independence while maintaining access to the Swiss group's research and client networks.

Does Sarasin & Partners participate in fund commitments or only direct deals?

The firm operates across both. Its traditional listed-market business manages direct equity, multi-asset, fixed income, and real estate portfolios through segregated mandates and pooled Charity Authorised Investment Funds (CAIFs). Through its 2022 acquisition of Bread Street Capital Partners, now Sarasin Bread Street, it also commits to private market funds and co-investments alongside external managers.

What is Sarasin & Partners' known posture on co-investments alongside external GPs?

The Sarasin Bread Street unit, formed in 2022, explicitly provides access to 'private market opportunities' — a scope that typically includes primary fund commitments and co-investment capabilities. Alex Barr and Guy Eastman, the senior private-market team, brought over 30 years of private equity investing experience from Aberdeen Standard Investments and SVG Advisers, where they managed fund-of-funds and direct co-investment programmes.

Which sectors does Sarasin & Partners explicitly avoid?

The firm does not publish an explicit exclusion list. However, its thematic investment process is built around six long-term themes paired with a stewardship framework that weaves ESG factors into research. The firm's Climate Active strategy, spearheaded by Head of Stewardship Natasha Landell-Mills, focuses engagement on climate-intensive sectors, which suggests underweight or selective exposure to high-carbon transition laggards.

How does Sarasin & Partners source proprietary deal flow?

The private markets side sources through its senior team's long-established network: Alex Barr and Guy Eastman have operated at the nexus of UK and European private equity for decades. On the listed side, deal flow originates from a global thematic filter — six long-term trends form the basis of the research framework — combined with a stewardship overlay that tracks corporate sustainability signals. The firm's deep charity-client base in the UK also provides a distinct distribution-sourcing tie to institutional consultant networks.

Does Sarasin & Partners maintain philanthropic structures, and how are they separated?

The firm itself does not operate a separate philanthropic foundation, but many senior team members hold personal trusteeships at charities such as Great Ormond Street Hospital Charity, the Parachute Regiment Charity, and the British Humane Association. Sarasin & Partners' core institutional franchise is managing assets for UK charities — with over £8.5bn in charity assets — which structurally embeds charitable governance within the client base rather than through a dedicated grant-making arm.
