Macmillan Ventures

Macmillan has been driving innovation in cancer since our inception in 1911 and is one of the UK’s most trusted brands. We leverage our unique patient and clinical insights to identify the biggest problems in cancer care and the most impactful solutions to solve them. Once we've made an investment, we work with our portfolio companies to accelerate their growth and impact.

In early 2026, we successfully completed our £3.5 million pilot impact investment fund and invested in eight pioneering companies. Now, we’re aiming to invest our second £30 million impact investment fund in more groundbreaking innovations over 5 years.

We invest in any innovation along the cancer-care continuum, from early diagnosis to treatment transformation, and living well beyond your treatment. We’re particularly interested in anything that improves health equity and shifts care into communities. We typically invest between £250k and £1 million at roughly Seed to Series A. And we're always open to hearing from you if you don't neatly fit into those categories.

By donating to Macmillan and becoming a Venture Partner, you will join a community of philanthropists and partners committed to ensuring that everyone affected by cancer in the UK has access to world-class care.
