Quality over quantity is the golden rule of B2B lead generation. HubSpot research shows that companies using targeted lead qualification see 77% higher conversion rates than those relying on broad, untargeted lists. The secret is qualifying leads before outreach, using firmographic filters to ensure prospects are worth your time.

What Are Firmographic Filters?

Firmographic data defines the characteristics of a business, just as demographics define individuals. This includes:

  • Company size and headcount
  • Industry and sector
  • Geographic location
  • Revenue and financial health
  • Technology stack and digital maturity

Salesforce reports that sales teams leveraging firmographic data achieve 28% higher revenue growth, proving its power as a pre-screening mechanism.

Essential Firmographic Criteria for Qualification

Company Size and Employee Count

A startup with 5 employees has very different needs to an enterprise with 5,000. Align outreach with size brackets such as:

  • Small businesses (1–50 employees)
  • Mid-market (51–500 employees)
  • Enterprise (500+)How to Qualify Leads Before Outreach Using Firmographic Filters

Industry and Sector

Targeting specific sectors ensures relevance. MarketingSherpa found industry-targeted campaigns see 58% higher CTRs. Consider:

  • Regulatory environment
  • Buying cycles
  • Common challenges
  • Tech adoption

Geographic Location

Location impacts communication, compliance, and relationship-building. UK prospects, for example, often prefer local suppliers for trust and support.

Revenue and Growth Signals

Financial health predicts purchasing potential. Look for revenue size, funding rounds, and year-on-year growth. Scaling companies are more receptive to new solutions.

Technology Stack

According to G2, 73% of B2B buyers prefer solutions integrating with existing tools. Understanding a prospect’s tech stack uncovers compatibility and intent signals.

Setting Up Effective Filters

  1. Define Your ICP – Analyse existing best-fit clients and map size, sector, geography, and tools in use.
  2. Use Multiple Data Sources – LinkedIn, company sites, industry directories, financial databases, and tech tracking tools.
  3. Implement Scoring – Assign weighted points (e.g. industry = 25, company size = 20, tech fit = 20). Leads over 70 points = immediate outreach.

Common Mistakes to Avoid

  • Over-narrowing criteria – Limits your addressable market.
  • Ignoring growth stages – Small but rapidly scaling companies may be future ideal clients.
  • Static filters – Markets evolve; review and adjust filters regularly.
