Amrize
Amrize is Sir Ronald Cohen's London family office, deploying capital from his Apax Partners legacy into social-impact and mission-driven investments...
Amrize
Amrize was established in 2001 as the private investment entity for Sir Ronald Cohen, the Egyptian-born, UK-raised financier who co-founded Apax Partners in 1971 and chaired the firm until 2005. The office manages liquidity created by Apax's evolution from a venture capital pioneer into one of the world's dominant private equity platforms, which today oversees roughly $77 billion. Cohen's personal wealth derives directly from his role in building that franchise, and Amrize represents the deployment vehicle for his post-Apax focus. The firm's strategy centers on what Cohen has termed 'invisible heart' economics — blending private capital with measurable public good. Amrize allocates across early-stage venture, growth equity, and innovative financing structures including social impact bonds, a concept Cohen helped pioneer through his chairmanship of the G8 Social Impact Investment Taskforce. Portfolio activity spans microfinance in emerging markets, affordable housing in the UK, and ventures advancing criminal justice reform. Cohen also co-founded Bridges Fund Management in 2002, a dedicated impact fund manager with over £1 billion under management, and served as a founding patron of Big Society Capital. Beyond direct investment, Amrize's influence extends through Cohen's role in shaping global impact policy. He chairs the Global Steering Group for Impact Investment and the Portland Trust, a non-profit promoting economic development between Israel and Palestine. Recent public activity includes the 2024 publication of a major report on mobilizing private capital for social challenges, co-authored with Harvard Kennedy School, reinforcing the office's thought-leadership posture. Cohen was knighted in 2001 and appointed to the Order of the Nile by Egypt in 2021. Amrize's structural distinction lies in its complete alignment with an individual's intellectual legacy rather than a diversified balance-sheet mandate. Unlike multi-generational family offices that broaden into real estate or public equities, Amrize concentrates on proving the thesis Cohen has championed for over two decades: that social returns are measurable, scalable, and compatible with market-rate financial returns. This creates a highly focused portfolio that behaves more like a foundation's endowment than a traditional single-family office.

Frequently asked questions
Who runs investment decisions at Amrize?
Sir Ronald Cohen serves as Chairman and is the primary investment decision-maker. His personal capital and intellectual framework drive the office's strategy. Cohen's investment philosophy was shaped by four decades building Apax Partners, one of Europe's largest private equity firms, which he co-founded in 1971 (per public record). Amrize does not disclose additional investment committee members publicly.
How does Amrize's impact-investing focus differ from a traditional family office?
Amrize's mandate is explicitly tied to Sir Ronald Cohen's identity as the architect of modern impact investing, rather than to a pure wealth-preservation goal. The office concentrates on social impact bonds, development finance, and mission-driven ventures — a portfolio that behaves more like a foundation's endowment than a diversified single-family office. Cohen's chairmanship of the Global Steering Group for Impact Investment and his role in founding Big Society Capital further embed this focus into the office's operations.
How is Amrize related to Apax Partners?
Amrize manages capital generated by Sir Ronald Cohen's role in co-founding and leading Apax Partners from 1971 until 2005. Apax Partners, which today manages roughly $77 billion (per the firm, 2024), was the primary source of Cohen's personal wealth. Amrize is an entirely separate entity and does not manage Apax fund capital, though the relationship provides the financial foundation for its impact-investing activities.
What investment structures does Amrize typically use?
Amrize deploys capital through direct early-stage investments, growth equity, and innovative financing vehicles — most notably social impact bonds, a structure Sir Ronald Cohen helped pioneer through the G8 Social Impact Investment Taskforce. The office also has ties to Bridges Fund Management, the dedicated impact fund manager Cohen co-founded in 2002, which manages over £1 billion (per Bridges, 2024).
Where does Amrize primarily deploy capital geographically?
The office's investments span the UK, emerging markets in Africa and the Middle East, and Israel/Palestine economic development initiatives. Its geographic footprint reflects Cohen's personal background — born in Egypt, raised in the UK, and active in Israeli-Palestinian economic cooperation through the Portland Trust, which he chairs.
