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: ▲930%; Now £624k
Cash at bank: ▼30%; Now £1.6m
Headcount: 0%; Now 11
Deferred income: ▼64%; Now £944k
Fixed assets: ▼43%; Now £53.1k

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