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: ▲17%; Now £9.7m
Cash at bank: ▲285%; Now £5.5m
Headcount: 0%; Now 3
Deferred income: ▲3469%; Now £25.7k
Fixed assets: ▲23%; Now £3.6m

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