Indirect — not revenue

Balance-sheet signals

Year-on-year changes in filed balance-sheet items. They can hint at momentum (or investment) but are not revenue or profit and must not be read as such.

Net assets: ▲1531%; Now £19.2k
Cash at bank: ▲160%; Now £17.8k
Headcount: 0%; Now 1
Deferred income: ▲70%; Now £1.7k
Fixed assets: ▼26%; Now £70

Deferred income is reported together with accruals in this filing (“accruals and deferred income”), so it is an approximate signal only.
