Pattern-match your actual book of business to discover the ICP you're already winning with.

When to use
Run this when your stated ICP and your actual book of business don't match — which is most agencies past year 2. Use it before a positioning rewrite, before hiring an SDR, or when you suspect you're undercharging a specific segment. Requires honest data on margin and tenure per client.
The prompt
You are an agency P&L analyst. You read between the lines of a client roster to find the ICP the agency is actually winning with — which is often different from the ICP they think they have.

Agency: [AGENCY_NAME]
Services: [SERVICES]
Full client roster with these fields per client: industry, size, services purchased, MRR, gross margin, tenure in months, NPS or sentiment, source (referral/outbound/inbound/partner): [CURRENT_CLIENT_LIST]
Stated ICP today: [STATED_ICP]

1. Segment the roster into clusters based on industry, size, and services purchased.
2. For each cluster, compute average MRR, average margin, average tenure, and a fit-score.
3. Identify the top 2 "hidden winners" — clusters that quietly outperform the stated ICP on margin x tenure.
4. Identify the top 2 "hidden losers" — clusters that look like wins on revenue but lose on margin or tenure.
5. Recommend a revised ICP statement based on the hidden winners.
6. Flag any single client whose departure would meaningfully change the picture (concentration risk).

- Margin and tenure trump revenue. A $10k/mo client at 15% margin who churns in 6 months loses to a $4k/mo client at 60% margin who stays 30 months.
- Don't romanticize the founder's favorite clients. Go where the numbers go.
- Call out where the data is too thin to draw conclusions.

Return:
1. Cluster table (cluster | n | avg MRR | avg margin | avg tenure | fit score)
2. Top 2 hidden winners (with the pattern that defines them)
3. Top 2 hidden losers (with the pattern + recommendation: fire, reprice, or downsize)
4. Revised ICP statement (1 paragraph)
5. Concentration risk callout
6. 3 changes to make in the next 30 days
Variables
  • [AGENCY_NAME] — Your agency's name
  • [SERVICES] — Services you sell
  • [CURRENT_CLIENT_LIST] — Paste client data with industry, size, services, MRR, margin, tenure, NPS, source
  • [STATED_ICP] — Your current public/internal ICP statement
Example input
AGENCY_NAME: Forge Media. SERVICES: SEO, content, paid search. STATED_ICP: B2B SaaS Series A-B, $5-20M ARR. CURRENT_CLIENT_LIST: 14 clients — 6 are B2B SaaS ($4-9k MRR, 30-45% margin, 8-14mo tenure), 4 are professional services firms (law/accounting, $3-5k MRR, 65% margin, 22-36mo tenure), 3 are e-com DTC ($6-12k MRR, 20% margin, 5-9mo tenure), 1 is a marketplace ($14k MRR, 50% margin, 28mo tenure).
Example output
| Cluster | n | Avg MRR | Avg Margin | Avg Tenure | Fit |
|---|---|---|---|---|---|
| B2B SaaS | 6 | $6.2k | 38% | 11mo | 6/10 |
| Pro services | 4 | $4.1k | 65% | 28mo | 9/10 |
| E-com DTC | 3 | $9k | 20% | 7mo | 3/10 |
| Marketplace | 1 | $14k | 50% | 28mo | n/a |

**Hidden winners:** Professional services firms. Lower revenue, but 65% margin and 28mo tenure means LTV is ~2x your stated-ICP B2B SaaS clients. Pattern: 10-40 employee law/accounting firms outside top-50 metros.

**Hidden losers:** E-com DTC. Looks shiny on MRR but 20% margins and churns under a year. Recommendation: stop selling to them; refer out.

**Revised ICP:** Professional services firms (legal, accounting, consulting), 10-40 employees, in secondary US metros, who need consistent organic lead flow.

**Concentration risk:** Marketplace client = 16% of revenue alone. Diversify.

**30-day changes:** (1) Rewrite homepage for pro services. (2) Sunset DTC pitches. (3) Ask each pro services client for 2 referrals.
Pro tips
  • Pull the data from your accounting tool, not your CRM — your CRM lies about margin.
  • Include NPS or a 1-5 sentiment guess. Tenure alone misses unhappy clients who just haven't churned yet.
  • If your hidden winner is in a niche you'd be embarrassed to specialize in, that's still a signal. Specialize anyway.
