Terra Industries, a Nigerian maker of autonomous defence and security systems, raised a further $18m on 17 August 2026, closing its seed round at about $52m.
The extension was backed largely by existing investors 8VC, Silent Ventures, Nova Global, Belief Capital and SV Angel. Norleo Space Investments and the angel investor Grant Gordon were new, Nairametrics reported. No lead investor was named, and no valuation was disclosed.
The company said it will open its first international office, in London, expand manufacturing capacity and speed up deployments across the Global South.
The company did not disclose how many people it employs.
“Critical infrastructure across the Global South is best protected by systems designed for these environments”Nathan Nwachuku, CEO, Terra Industries
What Terra does
Terra develops autonomous defence systems for governments and operators of critical infrastructure. WeeTracker, which put its headquarters in Abuja, described the focus as autonomous security systems and unmanned technology for protecting infrastructure across Africa.
Nairametrics reported that the technology is deployed in several African countries, protecting power plants, mines and other critical assets valued at about $11bn. The company was founded in 2024 by Nathan Nwachuku, who is chief executive, and Maxwell Maduka.
Nwachuku said critical infrastructure across the Global South is best protected by systems designed for its conditions. A London office, he added, puts Terra in the rooms where global defence decisions are made.
WeeTracker reported that after the February extension the seed round stood at $34m, so the latest $18m brings it to the roughly $52m total.
What the money is for
Besides the London office, Terra plans to grow its engineering, operations and business development teams. It also plans to expand into the Gulf, South America and South Asia, according to Nairametrics.
Manufacturing will stay in Africa. A 34,000-square-foot facility in Ghana, called Pax-2, is scheduled to open in the fourth quarter of 2026.
Nairametrics reported that Terra's technology already protects assets worth about $11bn. The new international office is meant to give the company access to the institutions involved in global defence and infrastructure markets, while production remains in Africa.
Three seed tranches
The seed round was raised in stages. In January 2026 Terra raised $11.75m, led by 8VC, with Valor Equity Partners, Lux Capital, SV Angel, Leblon Capital, Silent Ventures, Nova Global and the angel Micky Malka taking part.
In February it added $22m, led by Lux Capital, with Resilience17 Capital and existing investors 8VC and Nova Global. Nairametrics said that tranche closed in under two weeks.
Together with the new $18m, those rounds give the roughly $52m total. WeeTracker's account of the earlier tranches matched Nairametrics', and put the seed total before this extension at $34m.
WeeTracker listed the same lead investors for the earlier tranches, which means 8VC has backed the company across all three stages of the seed round.
A growing sector
Nwachuku said a London presence puts Terra in the rooms where global defence decisions are made. Terra did not disclose revenue or headcount.
Nairametrics quoted Nwachuku as saying the London office puts Terra in the rooms where global defence decisions are made, and the company describes its customers as governments and infrastructure operators.
