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: ▲19%; Now £5.2m
Cash at bank: ▲1884%; Now £16.3m
Headcount: ▼11%; Now 132
Deferred income: ▼24%; Now £2.7m
Fixed assets: ▼25%; Now £1.6m

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