Why Company Size Matters for B2B Sales

Company size is one of the most reliable predictors of purchasing behavior, sales cycle length, and budget availability. A solution that works for a 10-person startup may be completely different from what a 5,000-person enterprise needs.

Our employee count data enables segment-appropriate selling, ensuring your outreach, pricing, and product positioning align with each prospect's organizational reality and purchasing capacity.

Frequently Asked Questions

Common questions about our company size classification and domain database.

We aggregate employee data from multiple sources including LinkedIn company pages, job postings, company websites, and public filings. Our algorithms cross-reference these sources to generate accurate employee range estimates. We update this data weekly to reflect workforce changes.

Our employee count classification achieves 92% accuracy for range-based segmentation. We use broad ranges (1-10, 11-50, 51-500, etc.) rather than exact counts, which significantly improves reliability. For high-priority accounts, we recommend verifying employee counts during sales qualification.

Yes, our API supports flexible employee range filtering. You can query standard ranges (startups, SMB, mid-market, enterprise) or specify custom ranges. Common custom filters include "100-250 employees" for specific market segments or "200+" for upmarket targeting.

We update employee count data weekly for actively tracked companies. Companies with recent changes (hiring surges, layoffs, acquisitions) are prioritized for more frequent updates. Historical snapshots are available for tracking workforce growth over time.

Company size integrates seamlessly with all other data dimensions. You can filter mid-market companies by industry vertical, find enterprise businesses by funding stage, identify growing SMBs by hiring activity, or combine any attributes for precise targeting.
