TEKEVER Is Worth $6.4B After 50,000 Hours Over Ukraine

Most defense startups raise money on a promise of what their systems will do. TEKEVER raised on a flight log.

On September 23, the Portuguese drone maker announced the first close of a $580 million Series D at a $6.4 billion valuation. The round was led by UC Investments, the University of California's investment office, and Baillie Gifford, an existing backer. Merlyn Advisors joined as a new strategic investor, and Crescent Cove, Ventura Capital and Iberis Capital returned. The company says more closings are expected in the coming months, so $580 million is a floor, not the final size.

The number investors were paying for is this one: TEKEVER says its autonomous systems have logged more than 50,000 operational flight hours in Ukraine since Russia's full-scale invasion in 2022. That figure comes from the company and has not been independently audited. It is still the kind of evidence most drone startups cannot offer.

What TEKEVER actually builds

TEKEVER does not make the small first-person-view attack drones that dominate footage from the front. It makes long-endurance surveillance aircraft and the software around them. Tech.eu describes two main lines. The AR3 is a smaller, modular system. The AR5 is a larger aircraft with about 20 hours of endurance and a 50 kg payload. Both carry sensors, communications and onboard AI processing, with TEKEVER's own ground-control software.

The AR3 alone accounts for more than 10,000 of the Ukraine hours, according to reporting by The AI Insider and others citing the company. TEKEVER says frontline feedback led to more than 100 changes to the platform. That is the real asset. A surveillance drone that has been jammed, shot at and repaired in a live war for four years has been tested in ways no range trial can match, and the fixes are already built in.

The missions are mostly about seeing, not striking: battlefield intelligence, maritime patrol, border surveillance and search and rescue. That positioning matters to investors like a university endowment, which can more easily defend putting money into reconnaissance than into weapons.

The British contract that set the price

The valuation did not come from Ukraine alone. In late July, the UK Ministry of Defence selected TEKEVER to replace the British Army's Watchkeeper drones. On September 16, one week before the round was announced, the company signed the Project CORVUS contract, worth up to £400 million over ten years, to supply AR5-based aircraft for Army intelligence, surveillance and reconnaissance.

DroneXL reports the initial order is six aircraft, with up to 24 delivered by 2029. "Up to" is doing a lot of work in that £400 million figure, as it does in most framework contracts. Still, a ten-year program of record with a major NATO army is the kind of revenue visibility that supports a late-stage valuation. TEKEVER already manufactures in Swindon, England, which helps explain why a Portuguese company won a British sovereign-capability program.

The valuation jump

The markup is steep. DroneXL notes TEKEVER raised $74 million in November 2024 and passed a £1 billion valuation in May 2025. Sixteen months later, it is at $6.4 billion. The Next Web reports the company now employs more than 1,500 people and is expanding in the UK and France. It opened a US office in Fayetteville, North Carolina, in May.

That jump fits a wider pattern in European defense tech. The Next Web puts Helsing, the German defense AI company, at an $18 billion valuation after a $1.8 billion Series E in July. The asset class has moved from niche to consensus in about two years, driven by the war in Ukraine and European governments committing to higher defense budgets.

UC Investments is the notable name here. This is its first direct investment in Europe, and pension and endowment money usually arrives after a sector has proven it can survive. CIO Jagdeep Singh Bachher pointed to TEKEVER's two-decade history and operating record, which is the language of an institution buying durability rather than a moonshot.

What the money is for

TEKEVER is unusually direct about the plan. CEO Ricardo Mendes told The Next Web the raise supports growth "not only organically, developing new technology, but through acquisitions." He also said he expects the defense technology market to consolidate heavily over the next few years.

The buying has already started. On September 1, TEKEVER acquired Flowcopter, an Edinburgh company that works on hydraulic transmissions. On September 22, a day before the funding news, it signed a memorandum of understanding with Estonian drone maker Threod Systems, according to DroneXL.

That strategy makes sense. Europe's defense drone sector is crowded with small companies that each hold one piece of the stack, such as an airframe, a propulsion system or a sensor. Governments want fewer, larger suppliers who can deliver at volume and stay in business for the length of a ten-year contract. A company with a large war chest and a combat record can buy those pieces faster than it can build them.

What to watch

Three things will show whether $6.4 billion is justified. First, whether TEKEVER converts CORVUS's "up to" into actual deliveries on schedule. Second, whether the acquisitions integrate or become a collection of separate product lines. Third, whether the US office turns into American contracts, which would open a market far larger than the UK.

The broader lesson is about evidence. In 2026, the defense startups that command the highest prices are the ones with operating hours in a real conflict and a signed program of record. TEKEVER has both, and it is now betting the money on becoming a consolidator before someone larger consolidates it.
