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: ▲36%; Now £4.8m
Cash at bank: ▼5%; Now £315k
Headcount: ▲48%; Now 92
Deferred income: ▲23%; Now £165k
Fixed assets: ▲267%; Now £8m

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