Most stories about African tech companies "going global" involve a foreign company buying the African one outright. The story of hearX is different, and that difference is exactly what makes it worth telling.

hearX started life in 2015 as a spinout from the University of Pretoria, built around a deceptively simple idea, what if you could test someone's hearing using nothing more than a smartphone, instead of requiring a soundproof booth and a trained audiologist on site. That early focus on mobile based hearing diagnostics eventually led the company to launch Lexie Hearing in 2020, an over the counter hearing aid brand built with Bose, designed to be affordable enough and simple enough that people could buy it directly online or in retail stores, no prescription or clinic visit required. Lexie's mix of quality and accessibility earned hearX a spot on TIME's list of the 100 Most Influential Companies in 2023, a rare honour for a South African startup.

On the other side of the Atlantic, a US company called Eargo had spent years building its own version of the same mission, designing virtually invisible, rechargeable hearing aids aimed at people who wanted a discreet, modern alternative to traditional devices. Eargo built real credibility in the direct to consumer hearing aid space in America, but building hardware and managing clinical credibility is expensive, and the company needed a partner who could match its ambitions.

In March 2025, the two companies announced something more interesting than a simple buyout. Instead of one swallowing the other, hearX and Eargo merged into a single new entity called LXE Hearing, backed by a 100 million dollar investment from healthcare focused private equity firm Patient Square Capital. It was the first major consolidation in the over the counter hearing aid market since the US Food and Drug Administration created that regulatory category back in 2022, opening the door for hearing aids to be sold without a prescription in the first place.

The structure of the deal tells you a lot about how this was negotiated. hearX's CEO and co founder, Nic Klopper, took the top job at the newly combined company, with Eargo's COO and interim CEO, Bill Brownie, stepping into the COO role underneath him. Crucially, key leadership and operations stayed rooted in South Africa. This was not a case of a Pretoria startup getting absorbed into an American head office. It was a South African company stepping into the driver's seat of a combined global business.

Klopper described the logic simply, that Eargo's design work and clinical quality complemented hearX's Bose powered product line and its mobile app, and that together the combined company could "revolutionise hearing aids and hearing health." Under LXE Hearing, both the Eargo and Lexie Hearing brands continue to operate, now backed by a combined 25 years of hearing health experience, more than 50 peer reviewed studies, and roughly 68 patents between them.

The numbers since the merger suggest the bet is paying off. By early 2026, LXE Hearing reported that its combined brands had supported more than 3 million people across 192 countries with hearing care services and products. That is a meaningful jump in scale for a company that started as a handful of academics in Pretoria trying to make hearing tests cheaper and easier to access.

For Africa's broader healthtech sector, this merger says something worth paying attention to. The continent's tech success stories have mostly followed one script, build something useful locally, then get bought by a bigger foreign player once you prove the model works. hearX took a different route, building something good enough that a US company wanted to merge with it as something close to an equal, and leaving South African leadership in charge of the result. That is a meaningfully different story to tell the next generation of African healthtech founders who assume an exit always means losing control of what they built.
