Where Niche Scoring for B2B SaaS Breaks at Scale

Past 50 customers and 2-3 verticals, scoring breaks in predictable ways.

Failure Modes at Scale

• The matrix becomes about expansion, not picking. Different mental model. Same template fails.
• Sales has data the founder ignores. Pipeline data should outweigh judgment now. It often does not.
• Reachability scores go stale. Channels that worked at 0-50 customers (founder LinkedIn) do not at 200.
• Crowding scores get political. The team has favorites. Honest scoring slips.

The Fix

• Replace founder-led scoring with sales-data-led scoring once you have 50 closed deals.
• Score expansion candidates separately from new-segment candidates.
• Use win/loss data as a sixth criterion ("win rate against incumbents").
• Run it with three internal voices, not one.

When to Retire It

Once you have 100 customers and one clear winning ICP, you do not score for picking anymore. You score for expansion only. The original tool has done its job.
