The broadband provider is headquartered in Portsmouth
A Portsmouth business has been named as one of Britain's fastest-growing companies.
The south east has secured seven places in the ORESA Executive Search Growth Index 2026 ranking of Britain's 100 fastest-growing companies, led by Lewes-based wellness brand Ancient + Brave.
The company, which specialises in science-backed dietary supplements, ranked eighth nationally after achieving two-year compound annual growth in revenues of 295.2%.
It is joined near the top of the rankings by Portsmouth-headquartered full-fibre broadband provider Toob (19 nationally), based in Lakeside, North Harbour. Healthy ready-meal business Prep Kitchen (21), which is based in Gravesend, was also named among the top firms.
The wider south east cohort reflects the breadth of the region's growth economy, spanning consumer wellness, digital infrastructure, transport services, luxury retail and specialist manufacturing.
Orlando Martins, founder of Growth Index, said: "The South East has produced some of the most impressive growth stories in this year's rankings. From Ancient + Brave's science-backed wellness supplements to Toob's investment in digital infrastructure and Prep Kitchen's expansion in healthy eating, these businesses are showing that companies built around strong consumer trends can achieve exceptional growth when they execute well."
Other south east companies featured include Riverdale, Passenger, Christopher Ward and Sanders Senior Living.
Toob was also ranked as one of the fastest growing tech companies in the south east by The Sunday Times.
Founded in 2017 by former Vodafone directors, Nick Parbutt, 55, and Mike Banwell, 64, the Portsmouth company has connected more than 65,000 customers via its own infrastructure. In addition it also serves 45,000 customer across England and Scotland on the CityFibre network.
Toob secured more than £160 million of debt funding in 2023, to support its expansion across the south of England, helping sales almost triple to £14 million in 2024.
