This audience captures 75,000+ globally distributed high-growth companies filtered to verified 50%+ YoY headcount growth, enriched with funding data, hiring velocity by function, and decision-maker contacts.

## What's Included

- **Company Identity**: Verified name, primary domain, and headquarters location

## Use Cases

### High-Velocity Sales Targeting
Companies scaling headcount at 50%+ are evaluating new tools on compressed timelines. Use growth rate and hiring velocity by department to identify which function is driving expansion — a company adding 30 sales reps in 90 days needs CRM, enablement, and compensation tooling now.

### Recruiting and Staffing Services
High-growth companies are the highest-volume recruiters in the market. Filter by department hiring velocity and growth stage to identify clients who need staffing, recruiting technology, or employer branding services.

### SaaS Tool Expansion Sales
Existing customers growing at this rate represent natural expansion opportunities. Use the audience to identify which of your current accounts have hit the high-growth threshold — and which new prospects are scaling into your product's enterprise tier.

### VC Deal Sourcing
Headcount growth is a proxy for traction. Filter this audience by stage (seed, Series A) to surface early-stage companies showing exceptional velocity before they raise their next round and get picked up by competitive deal flow.
