Notes and limits
- HubSpot detected on the public web by licensed B2B firmographic and technographic data: a floor, not a census.
- Companies with 10–500 staff whose headcount grew 10%+ in a year, sorted by 1-year headcount growth (highest first). This is a sort order, not a ranking of every HubSpot user.
- Growth is the exact 1-year headcount change, rounded. Anything of 200% or more is shown only as "200%+ (estimated)" (small teams make such figures unreliable), and inside that group companies are listed largest first.
- Likely branches of larger groups are left out.
- Company-level data only: no personal contacts.

FAQ
- How do you know they use HubSpot?
- HubSpot was detected on the company's public web presence (licensed B2B firmographic and technographic data). Detection misses some users, so treat it as a floor.
- Why only growing companies?
- Growing companies buy services, integrations and add-ons. Companies that did not grow at least 10% are excluded so the list is worth calling.
- What do I get for $19?
- All 296 companies with website, city, industry, size, growth and revenue bands, as CSV, Excel and PDF. No personal contacts.
