About Mark Ransford
Mark Ransford is an angel investor based in London. His profiles list a PhD in Genetics and an MA in Zoology from Cambridge University, and an MBA from INSEAD.
His career started in consulting and finance. He was a business analyst at McKinsey & Company from 1997 to 1999. One profile also lists Goldman Sachs and Morgan Stanley, and a 2022 conference bio says he worked at McKinsey, Goldman and Apax Partners as an investor. He was a partner at Kingdom Zephyr in 2011 and a director at Actis from 2012 to 2013. From 2013 to 2015 he was a senior advisor at the Global Health Investment Fund. PitchBook also lists a past director role at Apax Partners.
Since 2015 he has described himself as a self-employed fintech investor and advisor. He has been a senior advisor at CVC Capital Partners since 2023. NFX Signal lists him as a founding partner at Double Prime LLP. PitchBook records him as a former board member of TransferGo and an advisor at Juo, and Tracxn lists a past board seat at BibliU. Crunchbase shows no companies founded by him, and I found no company he built or ran as a founder.
NFX Signal lists his angel positions as Lendable (from 2015), Zego (2017), Payhawk (2019) and Wayflyer (2020). One aggregator reports he joined Wayflyer's Series B in January 2022 and Zego's Series C in December 2021. In a 2022 conference bio he described himself as an active angel in global fintechs, including four unicorns, and as a shareholder in TransferGo and Assistensi.
Crunchbase shows 25 investments, 0 lead investments, 0 exits and 0 companies founded. Third-party databases report different totals. Crunchbase's public page shows 40 investments, PitchBook shows 35 and Tracxn shows 48, so treat any single count as approximate.
Tracxn lists acquisitions among his portfolio companies, including Kapaga (2022), Nook (2024) and FlowPay (2025). Crunchbase names Kapaga and Joe as exits. These exit records differ between sources.
Crunchbase counts 11 AI investments since 2023. The Crunchbase activity timeline shows a run of recent rounds he took part in:
Zango (July 2025), Low Observable Technology (August 2025), Silas Insurtech (September 2025), Lette AI (October 2025), Sumary (November 2025), Conveyd (December 2025), Talentir (June 2026) and Xylo (July 2026). Earlier AI-tagged names on his Crunchbase profile are Flowpay (March 2024), Desia (September 2024) and Little John.
One aggregator that draws on NFX Signal data lists Lette AI as pre-seed (October 2025), Silas Insurtech as pre-seed (September 2025) and Low Observable Technology as seed (August 2025). Crunchbase lists Sumary as pre-seed and Conveyd as seed. Many of these companies apply AI to financial services, insurance or compliance. StartupMag, for example, describes Zango as a London fintech that raised £3.5M to simplify compliance with AI.
Public databases describe him as a pre-seed and seed investor who also joins some Series A rounds. NFX Signal ranks him in fintech, payments and insurance at pre-seed and seed. One aggregator lists his geographies as the United Kingdom, France and Italy. Tracxn shows his top sectors as fintech and enterprise applications, and StartupMag lists AI, data, software and cyber security among his sectors. His portfolio is mostly European and includes some US companies.
I found no public statement from him on his check size or on what he looks for in a pitch. Aggregators publish round-size ranges, but those describe the rounds he joined, not his own cheques, so they are left out here. Founders can use his LinkedIn profile to approach him. His portfolio and the co-investors in each round suggest he is most relevant to founders with a fintech, insurance or financial-services angle.
