The only specific combined net-worth figure located for Edwina Dunn and Clive Humby is £90 million, reported in 2013 as their estimate in the Sunday Times Rich List. It is a historical estimate, not a verified figure for their wealth today. Reports separately put the proceeds from the staged sale of their company, Dunnhumby, to Tesco at about £93 million—but sale proceeds are not the same as current net worth.
What was Edwina Dunn and Clive Humby’s reported net worth?
A profile published on 23 July 2013 reported a combined net worth of £90 million for Dunn and Humby, attributing the estimate to the Sunday Times Rich List 2013. The profile does not establish how the estimate was divided between them. Read the 2013 profile.
That figure should be read as an estimate for 2013, not a current valuation. There is no newer attributable combined estimate or public disclosure in the sources cited here that establishes either person’s present assets. It would be misleading to treat £90 million as their 2026 net worth or to adjust it for inflation without further evidence.
How much did they receive from selling Dunnhumby to Tesco?
Historical reporting gives two related sale figures, which describe transaction proceeds rather than the founders’ current wealth:

| Figure | What it refers to | Source and date |
|---|---|---|
| About £93 million | Reported total proceeds from the staged sale of Dunnhumby to Tesco over several years | Clive Humby’s account in a 17 January 2011 interview; the 2013 profile also describes the staged purchase at approximately this amount. 2011 interview; 2013 profile |
| £48 million | Reported price for the final 10% stake sold to Tesco | Reported in the 2011 interview and the 2013 profile. 2011 interview; 2013 profile |
Humby described the total as “About £93m over the years” in the 2011 interview. The amount reflects reported sale proceeds over time; it does not reveal how much either founder retained after taxes, spending, or subsequent changes in assets and liabilities.
How did Dunnhumby build their wealth profile?
Dunn and Humby co-founded Dunnhumby in 1989. The company analyzed retailer transaction data to understand customer behavior and became closely associated with Tesco’s Clubcard programme. Tesco became a majority shareholder in 2001 and acquired the business in stages, completing the purchase around 2010–2011 according to historical accounts.
Dunn’s UK government biography identifies her as Dunnhumby’s co-founder and former CEO. Her official biography says the company had grown to 1,500 people by the time she and Humby retired from it in 2011. That employee count describes the company’s scale; it is not a measure of either founder’s wealth.
The couple’s official founders’ page describes their later work through Starcount, a data-science consultancy, and identifies Humby as a co-author of Scoring Points: How Tesco Continues to Win Customer Loyalty. These roles and activities provide career context but do not establish current income or personal assets. For the business story behind Clubcard, see Scoring Points.

Why the sale total and net-worth estimate are different
The two headline amounts answer different questions. About £93 million is a reported total for staged business-sale proceeds; £90 million is a reported combined wealth estimate for 2013. One cannot be substituted for the other: transaction proceeds do not show what remains in a person’s balance sheet, and the 2013 estimate does not disclose its calculation or individual split.
A Dunnhumby announcement dated 22 May 2026 named Jamie Samaha as the company’s incoming CEO, effective 20 July 2026. That update concerns the company’s leadership, not Dunn and Humby’s personal finances. See Dunnhumby’s news page.

- From the acclaimed, award-winning author of Alexander Hamilton: here is the essential, endlessly engrossing biography of John D. Rockefeller, Sr.—the Jekyll-and-Hyde of American capitalism.
- In the course of his nearly 98 years, Rockefeller was known as both a rapacious robber baron, whose Standard Oil Company rode roughshod over an industry, and a philanthropist who donated money lavishly to universities and medical centers.
- He was the terror of his competitors, the bogeyman of reformers, the delight of caricaturists—and an utter enigma.
