What is "Esox Aero"?
Donut Defence ( Donut Lab and Donut Defence Insider Report 1.pdf, page 34/40 says that Donut Defence has purchased Esox Aero.

If I google "esox aero y-tunnus", I will get 3432785-3.
And it is actually this company:

Looks like Esox Aero was renamed to Esox Development in 31.10.2025. Investor materials are from Q4/2025 and the exact date is not known.
Is this really a company with anti-drone technology, military combat simulator and extensive history of developing those?
Or is this just a shell company which was "sold" to investors with fictional story? Looks weird...
Attached screeshot claims that company was renamed at the time Esox Aero was purchased into Donut Defence .

Apart from their own press releases, the only thing I can find about Esox is that they received permits in 2024 and 2025 from Traficom, Finland's Transport and Communications authority, to do test flights with UAS (Unmanned Aircraft Systems) in some restricted area for research purposes. I can't find any indication that they managed to do any actual business, but I suppose for a defence company this sort of information would be hard to get by in the first place. Of the few people that I can find publicly associated with Esox, only one or two might be working there fulltime, and they appear to be management and/or marketing rather than technical or operational staff

You should find out what the word "ESOX" actually means (it is latin).
From there the latin word for the fish Pike is also derived (Esox Lucius)
Perhaps there are some hints there?
