Commentary

Current to 14 Oct 26

Contracted ARR was £3.4m at 30 Sep 2026, with 67 logos. Watch lost logos and the absence of new logos in the last two months, with logo retention at 72.7%.

Contracted ARR was £3.4m at 30 Sep 2026, as at 9 Oct 2026, across 67 logos, after two months of small net declines.

What moved: In September, net new ARR was -£12k: expand of £32k was outweighed by lost ARR of -£44k and no new logos. Over 12 months, land was £1.6m and lost was -£444k, with 12 lost logos.

Against target: Average ARR of £50k is on target and ARR growth % of 84.2% is outside tolerance but favourable. ARR, customers, logo retention, gross retention and net retention are outside tolerance and unfavourable.

Watch: Look at whether new logos return after none in August or September, and at lost logos, 12 over 12 months with logo retention at 72.7%.

Each column is a period end: flows over the period, stocks at its end; money in £000s. Monthly: each month end over its month. Quarterly: calendar quarter ends, each over its quarter. Annually: calendar year ends, each over its year (2022 from October, when the company started). Rolling: every month end over the quarter or the year to it. Ratios are plain ratios over the period, never annualised, so they read green or red against their illustrative targets only over a year.
