Bridges Fund Management
Bridges Fund Management was founded in London in 2002 by Michele Giddens, Simon Ruskell and Philip Newborough with a mandate to generate commercial returns while addressing social and environmental challenges. The firm operates as a B Corporation, formalizing its commitment to stakeholder governance. It manages capital for institutional investors, endowments, pension funds and family offices, with a focus on the UK and European markets (per Bridges, firm website). Bridges invests across three core strategies: private equity (typically control or significant minority stakes in growth-oriented SMEs), real estate (place-making and regeneration through its 'Sustainable Real Estate' funds), and sustainable infrastructure (renewable energy, clean transport, circular economy assets). Portfolio companies have included: the renewable energy company Anesco, the social housing provider GreenSquare Group, and the electric vehicle charging network Chargemaster (per Bridges, public record). Bridges emphasizes rigorous impact measurement alongside financial underwriting, using the UN Sustainable Development Goals as a framework. The firm has raised multiple institutional funds, including the Bridges Sustainable Growth Funds and the Bridges Property Alternatives Fund series. In 2023, Bridges closed its Sustainable Growth Fund III at £300M (per Bridges, 2023). The firm employs around 60 professionals as of 2025, with a single office in London (per Bridges, firm website). An adjacent entity, the Bridges Social Entrepreneurs Fund, provides smaller-scale capital to early-stage social enterprises. Bridges differentiates itself through its comprehensive impact-management system, which it calls the 'Impact Diamond'. This framework integrates environmental and social outcomes into every stage of the investment lifecycle — from origination and due diligence to portfolio monitoring and exit. By fundamentally linking impact to returns, Bridges argues it can unlock alpha from tailwinds such as decarbonisation and demographic change, rather than treating impact as a constraint.

Frequently asked questions
Who runs investment decisions at Bridges Fund Management?
Investment decisions are overseen by the Bridges investment committee, which includes co-founders Michele Giddens (Executive Chair) and Simon Ruskell (Chief Executive). Each of Bridges' three strategies — private equity, real estate and sustainable infrastructure — has its own dedicated investment team and lead partners (per Bridges, firm website).
How does Bridges source proprietary deal flow?
Bridges generates proprietary deal flow through its network of impact-focused intermediaries, its in-house research team analyzing macro sustainability trends, and its reputation as a specialist impact investor. The firm also sources co-investment opportunities from institutional partners, and its real estate team often originates projects through local authority partnerships and regeneration frameworks (per Bridges, firm website).
Is Bridges Fund Management structured as a family office or an asset manager?
Bridges is an institutional asset manager, not a family office. It manages third-party capital from pension funds, endowments, foundations and family offices. The firm is owned by its partners (including the co-founders) and retains an independent governance structure (per Bridges, firm website).
What investment stages does Bridges typically target?
Bridges' private equity strategy targets control and significant minority stakes in established, growth-oriented SMEs in the UK and Europe. Its real estate strategy focuses on value-add and development opportunities. The sustainable infrastructure strategy targets operating assets and greenfield projects (per Bridges, firm website).
Which sectors does Bridges explicitly avoid?
Bridges operates an explicit exclusion policy aligned with its impact mandate, avoiding investments in fossil fuels, tobacco, alcohol, gambling, weapons, and any activities with significant negative environmental or social outcomes. Its exclusion list is published as part of its responsible investment policy (per Bridges, firm website).
How does Bridges define and measure impact?
Bridges uses its proprietary 'Impact Diamond' framework to assess investments across four dimensions: Impact Intent (is the business designed to solve a social/environmental problem?), Impact Contribution (can Bridges' capital add to the impact?), Impact Risk (what are the downside risks?), and Impact Performance (are outcomes measurable and improving?). The firm also uses third-party verification where possible (per Bridges, firm website).
Does Bridges maintain philanthropic structures, and how are they separated?
Bridges maintains a dedicated philanthropic arm called the Bridges Social Entrepreneurs Fund, which provides charitable capital and capacity-building support to early-stage social enterprises. This fund is distinct from the main for-profit funds and is managed with a separate governance framework (per Bridges, firm website).
