Quick Bio

Early Life and Education

Poppy Gustafsson was born on 24 August 1982 in Huntingdon, Cambridgeshire, where she grew up in a family that valued both business and storytelling. Her father, John Prentis, ran an agricultural-sales company, while her mother, Gilly Prentis, worked as a journalist for Farmers Weekly. This combination of commerce and communication laid a unique foundation for her future career.

Her academic talent shone early, and she pursued mathematics at the University of Sheffield, graduating in 2003 with a degree that would later serve as the bedrock of her analytical and business skills. After university, she trained at Deloitte and qualified as a chartered accountant, gaining the professional expertise needed to navigate finance, investment, and eventually entrepreneurship.

Starting Her Career

Before becoming a household name in cybersecurity, Poppy Gustafsson built her reputation in finance and technology companies. She worked at Deloitte as an Assistant Manager, later moving to Amadeus Capital Partners as a fund accountant. These roles gave her first-hand exposure to investment ecosystems and the workings of emerging technology businesses.

In 2009, she joined Autonomy, a British software company, where she served as Corporate Controller until its acquisition by Hewlett-Packard. This role further deepened her understanding of technology-driven businesses, priming her for the challenges and opportunities that awaited in the fast-growing world of cybersecurity.

The Birth of Darktrace

In 2013, Gustafsson co-founded Darktrace, alongside a team of mathematicians, intelligence experts, and technology investors. The company’s mission was clear—to use artificial intelligence to detect and neutralize cyber threats before they could cause damage. With the rise of digitalization and cybercrime, Darktrace’s AI-driven “enterprise immune system” model became revolutionary.

Initially serving as CFO, Poppy Gustafsson played a crucial role in shaping Darktrace’s financial strategy and growth. By 2016, she was appointed co-CEO, and by 2020, she became the sole Chief Executive Officer. Under her leadership, Darktrace expanded globally, building a reputation as a pioneer in AI-powered cybersecurity solutions.

Leading Darktrace to Global Success

As CEO, Gustafsson’s leadership brought Darktrace to the London Stock Exchange in 2021. The IPO was a defining moment for the UK tech sector, with Darktrace valued at billions of pounds, cementing its status as one of Britain’s most successful technology firms. Her leadership style, combining financial precision with bold innovation, made her a standout figure in the global tech landscape.

Despite the company’s meteoric rise, Darktrace also faced scrutiny. In 2023, short-seller allegations prompted an independent review by EY. While the review found some inconsistencies, they were not deemed material, allowing the company to move forward. These episodes highlighted both the strengths and the controversies tied to rapid corporate growth under intense market pressure.

Transition to Government

After more than a decade leading Darktrace, Poppy Gustafsson stepped down as CEO in September 2024, following the company’s £4.2 billion acquisition by US private equity firm Thoma Bravo. Her successor, Jill Popelka, took over as CEO, while Gustafsson remained on the board as a non-executive director.

Shortly after leaving Darktrace, she was appointed as the UK Minister of State for Investment in October 2024. This move marked a dramatic shift from private enterprise to public service. To take up her new responsibilities, she was granted a life peerage as Baroness Gustafsson of Chesterton, giving her a seat in the House of Lords.

Recognition and Awards

Poppy Gustafsson’s contributions have been widely acknowledged. She received an OBE in 2019 for her services to cybersecurity, followed by a CBE in the 2025 New Year Honours list. The University of Sheffield, recognizing her achievements, awarded her an Honorary Doctor of Science in 2022. She has also been named Tech Businesswoman of the Year (2019) and CEO of the Year (2021) at multiple prestigious awards.

These accolades reflect not only her professional success but also her influence as a female leader in industries often dominated by men.
