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: ▲49%; Now £1.2m
Cash at bank: ▲14%; Now £111k
Headcount: ▲3%; Now 448
Deferred income: ▼36%; Now £237k
Fixed assets: ▼56%; Now £43.7k

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