Tekever raises $580M Series D at a $6.4B valuation

Tekever has raised a $580 million Series D first close co-led by UC Investments and Baillie Gifford, valuing the Lisbon-founded drone maker at $6.4 billion as it prepares acquisitions and a deeper international push.

For years the refrain was the same: Europe can prototype defence tech, but the scale-up cheques get signed in the US, and sooner or later the companies follow the money across the Atlantic. The cheque did come from California this time. The company is staying in Lisbon.

Below, I lay out the round, the 25-year build behind it, and what the University of California’s first direct investment in Europe says about where defence capital flows next.

A $580M first close, co-led from California and Edinburgh

Tekever announced on 23 September 2026 a $580 million first close of its Series D, co-led by UC Investments, which manages the University of California’s endowment and pension capital, and Edinburgh-based Baillie Gifford. The round values the company at $6.4 billion post-money, and further closings are expected in the coming months, per the company.

Merlyn Advisors joins as a new strategic investor, and Crescent Cove, Ventura Capital and Lisbon’s Iberis Capital all return. The new valuation is nearly five times the roughly $1.3 billion Tekever commanded at its 2025 round – a repricing very few European scale-ups outside the AI model builders have managed in sixteen months.

The money goes, in the company’s words, to deepening its international presence, expanding its industrial and technological capabilities, and accelerating strategic acquisitions. CEO Ricardo Mendes called the round “far more than a capital raise” and noted that UC Investments chose Tekever for its first direct investment in Europe.

Twenty-five years from a Lisbon lab to 900 people

Tekever is nobody’s overnight success. Ricardo Mendes founded it in 2001 with classmates from Lisbon’s Instituto Superior Técnico, and the company built software and aerospace subsystems long before drones were something Europe funded. The Tekever of 2026 sells answers rather than airframes: surveillance as a subscription, with the AR3 and AR5 aircraft, sensors, communications and AI data processing bundled into one service.

Ukraine turned that model into the reference. The company reports more than 50,000 operational flight hours there since 2022. The UK Home Office flies Tekever drones over the Channel, and on 16 September the British Army selected the AR5 for CORVUS, a surveillance programme worth up to £400 million over ten years that replaces its Watchkeeper fleet.

Tekever says it is profitable, with headcount up 40% in a year to around 900 people – both company figures. And the acquisition strategy is already visible: Scottish heavy-lift drone startup Flowcopter was acquired on 1 September, and a partnership MoU with Estonia’s Threod Systems landed on 22 September, the day before the round.

A market tripling to $109 billion by 2031

The military drone market is estimated at $34.85 billion in 2026 and projected to reach $109.22 billion by 2031, a 25.7% CAGR (MarketsandMarkets, May 2026). Markets do not triple in five years because buyers are curious; they triple because procurement doctrine changed, and Ukraine changed it.

For scale against our own records: EnduroSat’s $205 million round was September’s benchmark raise in European dual-use hardware, and Tekever’s first close is nearly three times larger. At the other end of the funnel, Arcos raised a €5.5 million seed for civil security infrastructure only last week. The pipeline behind the champions is filling at every stage, and all of it lands in our fundraising data.

What a pension fund in a Lisbon cap table changes

So what is actually new here? First, the capital itself. UC Investments is pension and endowment money, the most conservative allocator class there is, and it chose a Lisbon drone company for its first direct European investment rather than going through a fund. When allocators of that size stop sampling Europe through intermediaries and start writing direct cheques, defence tech has changed category as an asset class.

Second, the geography. We keep telling ourselves that Europe’s defence champions can only come out of Munich or London. The good news is the map is wider than the narrative: the largest European defence round of the season belongs to Portugal, a country most ecosystem rankings still file under “emerging”.

Third, the consolidation. With acquisition capital and a $6.4 billion currency, Tekever can do what Europe’s fragmented drone industry has needed for years: pull the specialists together, from Scottish propulsion to Estonian airframes, around one combat-proven data flywheel. Watch which company gets the next call.

The false story is that Europe cannot fund its own security ambitions. The real one is that 25 years of patient engineering in Lisbon just became a $6.4 billion company without leaving home, and the world’s most cautious capital showed up to back it. Let’s watch who follows.
