The valuation of ElevenLabs has doubled to $22bn, or about £16bn, after the London-based AI voice company completed a $300m sale of employee shares, as reported by City A.M. and Tech.eu.
Worth unpacking what that figure is not. This was a tender offer, not a funding round. No new money went into the company itself. Instead, staff cashed out some of their shares at a price that implies the business is now worth twice the $11bn valuation from its February Series D, a primary round that raised $500m.
Secondary sales like this are how private companies give early employees liquidity without an initial public offering, and the price buyers are willing to pay becomes, in practice, the market’s read on what the company is worth. That ElevenLabs has run previous tender offers shows it has managed to keep that channel open while staying private.
The broader story sits well beyond the company itself. A British AI firm carrying a valuation larger than the combined market value of most of the FTSE 250 reinforces the argument that London can produce global winners in a sector dominated by American giants. It also lands in a week when UK tech leaders have been pressing the government for a £20bn push on sovereign AI, a number that suddenly reads as modest against private market appetite.
The cautionary note writes itself, in fairness. Tender prices are set by a handful of transactions between motivated buyers and sellers, and valuations that double in seven months can also shrink. Whether the price at which employees are selling reflects sustainable revenue or enthusiasm for voice AI is the question any careful observer should keep asking.
What the tender does prove, at minimum, is that secondary-market buyers can be found for UK AI equity at scale, and that a company can grow its headcount’s paper wealth without ever listing. The company confirmed the tender and the valuation on its own blog, with City A.M. and Tech.eu reporting the details and context.
