Matt Clifford

Who they are

Matt Clifford is co-founder and Chair of Entrepreneurs First — he stepped back from the CEO role after 12 years to lead the UK's 2023 AI Safety Summit at Bletchley Park as the Prime Minister's representative, and co-authored 'How to Be a Founder', the 2023 Startup Book of the Year.

Person

Matt transitioned to the Chair role at Entrepreneurs First in December 2023, handing the CEO seat to co-founder Alice Bentinck after running the firm from a pre-seed idea into a portfolio worth over $15 billion. He read at Oxford, then went to MIT for graduate work in programming languages and data analysis, before cutting his teeth as a consultant at McKinsey — a classic route that he then broke entirely by co-founding EF in 2011 with no external funding and a novel thesis: back the person before the company exists. Alongside EF he co-founded Code First Girls, a nonprofit teaching women to code, where he serves as non-executive director. He also co-authored 'How to Be a Founder' with Alice Bentinck, which won the 2023 Startup Book of the Year. His public voice is substantial: the 'Thoughts in Between' newsletter and podcast at tib.matthewclifford.com covers AI policy, geopolitics, scientific progress, and entrepreneurship, and he has spoken at the World Economic Forum and London Tech Week. The through-line is institution-building at the intersection of talent, technology, and policy — from company-builder to government AI adviser.

Company

Entrepreneurs First raised a $40 million Series B in 2025 at a $340 million valuation, following a Series A in 2024 — the clearest signal yet that the talent-first model is attracting significant outside capital. The firm now sits in Chair mode for Clifford, with Alice Bentinck running day-to-day operations as CEO since December 2023. EF's portfolio companies are collectively worth over $15 billion, built on a model that recruits exceptional technical individuals before they have a co-founder or idea. Reid Hoffman led a $12.4 million investment in 2017, and the firm has since expanded internationally.

Market

Entrepreneurs First occupies a distinct niche as a pre-team, pre-idea talent investor — sitting upstream of traditional seed funds and accelerators like Y Combinator, which require a formed team. The firm is recognized among notable early-stage investors helping pre-product, pre-revenue companies scale and connect with early customers. Its closest comparables are other talent-investor models, but few operate at EF's international scale or with its deep-tech focus.

Network

Clifford's closest professional anchor is Alice Bentinck — co-founder of both Entrepreneurs First and Code First Girls, co-author, and now his successor as CEO. Reid Hoffman backed EF with a $12.4 million investment in 2017 and remains an associated investor. Demis Hassabis and Mustafa Suleyman are noted as associated with the EF network, and Clifford has directly advised UK Prime Ministers Boris Johnson and Rishi Sunak on AI strategy.

How they likely show up

Co-founder and CEO of EF for 12 years, then transitioned to Chair → thinks in decade-long institution-building arcs, not annual cycles.
Stepped out of the operational CEO seat voluntarily to focus on AI policy work → comfortable ceding day-to-day control when a larger strategic bet calls for it.
Runs 'Thoughts in Between' as both newsletter and podcast, covering AI policy, geopolitics, and entrepreneurship → processes ideas publicly and iteratively; likely arrives at meetings with formed views, not open questions.
Hybrid role pattern (Chair at EF, government adviser, public writer, speaker) → operates across multiple contexts simultaneously; values breadth of influence over depth of one domain.
Co-founded two institutions (EF and Code First Girls) alongside the full-time CEO track → high agency on structural problems; builds the infrastructure when he doesn't see it existing.
Led the UK government's 2023 AI Safety Summit preparations as Prime Minister's representative → comfortable operating at the intersection of government, industry, and research; reads rooms across those three cultures.

Conversation tips

→ Reference a specific issue of 'Thoughts in Between' — it signals you've engaged with his actual thinking, not just his biography.
→ Ask about the transition from CEO to Chair and adviser — he made a deliberate bet that AI policy was more important than running EF daily; he'll have a clear view on why.
→ Don't treat EF and his government work as separate tracks — in his framing they're the same thesis (talent + technology = national prosperity), just operating at different scales.
→ He co-authored a book on founding; if the conversation touches on company-building, he has structured, teachable views — engage with the frameworks, don't just nod.
→ Cite the Bletchley Summit specifically rather than generic 'AI safety work' — it was a named moment he led, and the distinction between that and vague policy interest matters to him.

Toolbox

Openers

Open on the Bletchley Park AI Safety Summit — he served as the Prime Minister's representative leading preparatory work for the 2023 event, which is a specific, named inflection point where his company-building and policy worlds merged in public.
Mention 'Thoughts in Between' by name — his newsletter and podcast at tib.matthewclifford.com covers AI policy, geopolitics, and entrepreneurship, and naming the property signals you've engaged with his actual output, not his Wikipedia page.
Reference the EF Series B — a $40 million round in 2025 at a $340 million valuation on a model he built from scratch in 2011 with no funding; it's a concrete vindication of the talent-first thesis worth acknowledging.

Discovery questions

When you moved from CEO to Chair in December 2023, what did you think EF needed from you that it couldn't get while you were running it day-to-day?
The AI Safety Summit was a one-time event, but the policy questions it surfaced are ongoing — where do you think the UK has actually moved since Bletchley, and where has it stalled?
EF's model bets on backing the person before the idea exists — after a $340 million valuation and a portfolio worth over $15 billion, do you think the talent-investor model has been validated, or are you still proving something?

Avoid

Don't treat his government advisory work as separate from or more prestigious than EF — he built EF first, the policy platform followed from it, and framing the advising as his 'real' impact will land wrong.
