Transparent and explainable
The fit score reflects how well a company matches your multi-signal criteria. It's straightforward, auditable, and based on the specific combination of signals you define.
What the score reflects
- Number of your criteria matched (5 out of 6 signals = higher score)
- Website content alignment (mentions required keywords, excludes unwanted ones)
- Growth + operational signals combined (growing fast + missing key capability)
- Signal strength (how clearly the indicators appear in our data)
What it doesn't predict
- Buying intent or timing
- Budget availability
- Decision-maker accessibility
- Competitive positioning
Example scoring:
If you search for "growing + selling to enterprise + no SOC2", a company matching all three signals scores 95+, while a company matching only two scores 70-85.
Why this matters: Many lead scoring tools claim to predict buying intent. We don't. The fit score simply tells you which companies match your stated criteria—nothing more, nothing less.
Traditional tools vs. Firmbase
Sales Navigator gives you:
- Industry categories
- Company size (employees, revenue)
- Location and region
- Basic technology filters
Firmbase gives you all of that, PLUS:
- Growth rates from official company filings
- Website content analysis ("mentions X but not Y")
- Operational maturity signals from careers pages
- Multi-signal combinations impossible elsewhere
Example: "Growing SaaS companies without SOC2 certification" requires analyzing growth data AND website content. Sales Navigator has neither growth rates nor content analysis.
Multiple data sources, one search
This combination lets you search for "growing manufacturers without ERP systems" or "B2B SaaS selling to enterprise without security certifications"—queries impossible with demographic filters alone.

Built for B2B teams with complex ICPs
If your ideal customer can be found in Sales Navigator, you probably don't need us. We're for teams whose ICP requires nuance.
B2B service providers
Consultancies and agencies selling to growth-stage companies
Your perfect client has multiple characteristics—growth stage, operational gaps, market signals—that don't fit in dropdown menus. Find companies showing the specific combination that makes them ideal.
Software companies
Cross-industry platforms, emerging categories, or any software where ICP isn't defined by sector
You can't just target "manufacturing" or "SaaS companies." Your ICP is based on operational signals, tech maturity, regulatory needs, or signs of the problem you solve—not industry demographics.
Not for everyone
If your ICP is "UK banks with £1B+ revenue" or "all SaaS companies," traditional tools will serve you fine. We're for teams who know exactly what they're looking for but can't filter for it.
