Tekever, the Lisbon-founded maker of AI-enabled surveillance drones, announced on 23 September the first close of a $580 million Series D — more than €500 million — at a valuation of $6.4 billion, or more than €5.5 billion. The round was led by UC Investments, the investment arm of the University of California, and the Scottish fund manager Baillie Gifford. For UC Investments it is the first direct investment in a European company.

Merlyn Advisors joined as a new strategic investor; its portfolio manager is Sir Ben Wallace, the former UK defence secretary. Existing shareholders Crescent Cove, Ventura Capital and Iberis Capital also put in more money. Tekever said the first close covers most of the raise and that it expects further closings “over the coming months” to bring in new strategic investors. Portuguese business press described the result as the most valuable technology company ever headquartered in Portugal.

How fast the valuation moved

The round had been trailed for weeks. On 13 August Bloomberg reported that Tekever was in talks to raise up to €500 million at a €5.5 billion valuation, which it described as a fivefold jump on the previous year. The deal came in at that level. It follows the company’s selection by the UK Ministry of Defence for CORVUS, the British Army’s new surveillance capability, a programme worth up to £400 million over ten years and built on Tekever’s AR5 long-endurance drone.

Ricardo Mendes, Tekever’s founder and chief executive, told ECO that a stock-market listing is “on the horizon” and that the company is already preparing its internal processes and infrastructure for a possible IPO “if we identify the right moment”. He declined to give revenue figures but, asked whether annual growth was well above 20 percent, answered: “We are practically doubling.” The company says the money will deepen its international presence, expand industrial and technological capacity and “accelerate strategic acquisitions”.

Who is — and is not — on the cap table

The investor list is American, British and Portuguese. None of the named investors in this round is Nordic, and Tekever has not said which strategic investors it hopes to add in the later closings. That matters for the corridor: Nordic governments are among the most active funders of drone procurement in Europe, and a Nordic strategic or institutional investor in a later tranche would be a meaningful signal. For now the Nordic link runs through customers and partners, not shareholders.

The Nordic and Baltic footprint the money lands on

NorthSouth HQ has tracked that link all year. In March, Tekever completed in-flight integration of SpectraLoc, a passive radio-frequency detection payload from the Odense company Quadsat, on its AR3 EVO drone — a Portuguese airframe flying Danish electronic-warfare kit. In May it opened an office in Estonia, hired Tuuli Vors as Baltic market lead and put the AR3 EVO into Spring Storm 2026, the Estonian Defence Forces’ largest annual exercise, in which Nordic units also take part.

The larger channel is pooled procurement for Ukraine. Denmark, Norway, Sweden and Iceland are among the donors to the UK-run International Fund for Ukraine, and Tekever was one of three suppliers selected for the UK’s £752 million, 120,000-drone package announced in April. In July it bought the Portuguese AI software start-up Cloudsweep. With more than 1,300 employees before this round, it now has the capital to repeat that kind of deal at a much larger scale.

What to watch

Three things will show whether the Series D changes Tekever’s position in the Nordic market. First, acquisitions: Tekever has named M&A as a use of funds, and the Nordic and Baltic region has a dense cluster of small drone, sensor and counter-drone companies. Second, the later Series D closings and whether any Nordic investor appears. Third, direct orders: so far the Nordic countries have mostly paid for Tekever systems through the Ukraine fund rather than buying for their own forces.

Why this matters for the corridor

Tekever is the clearest case of a Portuguese company whose growth is being pulled by northern European defence spending. A €5.5 billion valuation, a funded acquisition strategy and a stated IPO ambition make it the reference point for Portuguese defence and dual-use suppliers looking north — and a likely buyer, partner or competitor for Nordic companies in the same field. For Portuguese exporters, the lesson is that Nordic and Baltic defence ministries reward suppliers that show up locally: an office in Tallinn, a Danish payload on the aircraft, a place in the exercises.
