Same request, same model, once with the skill and once without. Read both and judge for yourself.

“Turn this into a short update for our CEO.”

Source material given with the request

Quarterly numbers, Q2 2026 -> Q3 2026 (Holloway, B2B scheduling software) Total revenue: $4.10M -> $4.35M Enterprise revenue: $2.60M -> $2.95M SMB revenue: $1.50M -> $1.40M Enterprise monthly logo churn: 0.8% -> 0.7% SMB monthly logo churn: 3.1% -> 5.4% New SMB signups per month: 410 -> 405 SMB median first support response: 4 h -> 19 h (support moved to an enterprise-first queue in July) Data source: billing warehouse, finance-reconciled. Churn = accounts cancelled / accounts at start of month.
with the skill
**Q3 2026: Revenue grew 6.1%, but enterprise gains masked SMB deterioration.** Holloway’s revenue rose to **$4.35M**, up $250K from Q2. Enterprise drove the growth, adding $350K (+13.5%), while SMB revenue fell $100K (−6.7%). - **Enterprise strengthened:** Monthly logo churn improved from 0.8% to 0.7%. - **SMB retention worsened:** Monthly logo churn rose from 3.1% to 5.4%, while new signups remained nearly flat at 405 per month versus 410. - **Support warrants immediate attention:** SMB median first-response time increased from 4 to 19 hours after July’s shift to an enterprise-first queue. The timing suggests a potential contributor to churn, but does not establish causation. **Recommended next step:** Restore faster SMB support coverage and investigate cancellation reasons to determine whether the queue change is contributing to losses. *Source: finance-reconciled billing warehouse. Monthly logo churn = accounts cancelled / accounts at start of month.*
without
**Q3 2026 update — Holloway** Revenue grew **6.1% quarter over quarter to $4.35M**, driven by enterprise growth of **13.5% to $2.95M**. Enterprise monthly logo churn also improved, from 0.8% to 0.7%. **SMB retention is the key concern.** SMB revenue fell 6.7% to $1.40M, while monthly logo churn rose from 3.1% to 5.4%. New signups remained nearly flat at 405 per month versus 410. SMB median first support response increased from **4 to 19 hours** following July’s shift to an enterprise-first queue. This warrants investigation as a potential contributor to churn, not a confirmed cause. **Recommended priority:** Address SMB support delays and diagnose cancellations while sustaining enterprise momentum. *Source: finance-reconciled billing warehouse.*
