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: ▲27%; Now £18.1m
Cash at bank: ▲65%; Now £13m
Headcount: ▲9%; Now 268
Deferred income: ▲157%; Now £13.8m
Fixed assets: ▲85%; Now £4.3m

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