South African insurance mogul Adrian Gore onced feared Discovery Bank would fail

South African insurance tycoon Adrian Gore, who founded Discovery Ltd. in 1992 and built it into one of the country's largest financial services groups, says the launch of Discovery Bank caused the only night in his career when he woke up in a cold sweat.

"During my long journey in building Discovery, there was only one night that I woke up in a cold sweat," Gore writes in The Four Principles: Multiply Your Impact in Life and Leadership, a book published by Pan Macmillan in July.

His worry was the numbers. A digital bank carries largely fixed costs and only starts to make money once it reaches scale, and Discovery Bank needed to sign up clients at a steady weekly pace to stay on its plan. It was not getting there. "I was deeply concerned about the sheer number of new clients we'd need to bring in each week to stay on track and alarmed by how far behind we were falling," Gore writes.

A memory from America

What turned concern into alarm was Discovery's earlier failure in the U.S. The group launched Destiny Health there in the early 2000s, exporting its Vitality model, which rewards members for exercise and healthy habits. Destiny struggled to win enough members and paid more for their health care than its much larger competitors did. In February 2008, Discovery said it would exit the U.S. retail health insurance market after Destiny's losses breached limits set by its board. The venture cost the group about $100 million between 2003 and 2008.

"It was the experience of Destiny Health in the US that made me sit bolt upright in my bed and, for the first time in over two decades, I thought we may not make it," Gore writes.

Discovery had already committed heavily to the bank. By the end of 2018 it had spent about R6 billion ($360.1 million) on the project, including R3.28 billion ($196.9 million) paid to FirstRand Ltd. to take full control of the Discovery credit card business the two companies had run together. The bank opened to beta testers in November 2018 and launched to the public in 2019, pitching itself as a "behavioural bank" that links interest rates and rewards to how clients manage their money and their health.

Gore says he tried to keep his attention on the plan rather than the warnings. "At the time, I tried not to fixate on the plethora of negative scenarios landing on my desk, instead focusing on the uniqueness and soundness of our idea," he writes. "Our planning had been meticulous: we had stress-tested our models and carefully plotted the path forward."

A new chief executive

The fix included a change at the top. Hylton Kallner, who ran Discovery's South African businesses and had spent about a decade as the group's chief marketing officer, became chief executive of Discovery Bank in January 2021. He replaced Barry Hore, who had overseen the bank's build and its migration of credit card clients. Gore says the bank had to tie Vitality incentives more closely into its products. "In my view, the changes that were necessary were so dramatic that they required a bold new leader," he writes.

The bank is now profitable. In the year to June 30, 2026, Discovery Bank reported normalised profit from operations of R370 million ($22.2 million), compared with a loss of R68 million ($4.1 million) a year earlier. Its client base grew 26% to 1.57 million, revenue climbed 31% to R3.1 billion ($186.1 million), and 70% of new business came from people outside the Discovery group. Retail deposits rose to R27.2 billion ($1.63 billion).

Discovery is targeting annual bank profit of R3 billion ($180.1 million) by 2029. On Oct. 1 it began the second phase of what it calls its "super bank" strategy, which aims to make the bank the main platform for the group's health, life insurance, investment and banking products. Group normalised profit from operations rose 17% to R17.75 billion ($1.07 billion) in the same financial year.

The stake behind the story

Gore's 6.69% stake in Discovery was worth close to $1 billion in July, putting him within reach of dollar-billionaire status.

His book sets out four principles he credits for Discovery's growth: disciplined optimism, focused urgency, declared goals and what he calls the Pareto tail. He uses the bank episode to make the case for the first of them, writing that his refusal "to succumb to a default negative position" during that period "has been vindicated."
