Beckham launched her fashion brand in 2008, and has since boosted its fortunes by expanding into beauty products and luxury accessories.
The company has seen double-digit revenue growth for the past three years, and said it finally became profitable in 2022.
However, shareholders including the Beckhams had to provide a £6.9m cash injection in 2023, when operating losses stood at £200,000.
In an interview with Harper’s Bazaar, she said: “The company has been through so much over the last 17 years – ups, downs, restructuring… it’s been quite the journey.
“So, finally, to be able to say we’re profitable is something I’m so proud of, because it’s not an easy industry, and it’s getting harder and harder.”
