Sifted examines why revenue in the defence tech sector is "blurry" compared with the clean recurring-revenue model that many venture investors expect. The piece focuses on how startups in this space report revenue and how that reporting interacts with metrics like annual recurring revenue (ARR).

For defence tech, revenue often comes through contracts that do not behave like subscription software, making ARR an awkward lens for judging performance. Sifted suggests this mismatch creates a transparency problem for VCs who rely on familiar metrics to compare startups across sectors.
