What the IT function covers
Everyone who builds, runs or secures the technology estate: software engineering, infrastructure and networking, data platforms, cloud, cybersecurity, and the service desk that keeps everyone else working. This is the single largest function in the file, and the usual buying center for software, infrastructure and security vendors.

Go deeper in the Count Explorer
Everything above is an exact count for IT on its own. To put IT together with a second filter — a title level, a job function, a company size band, a revenue band — open it in the Count Explorer. It arrives with IT already selected, and it tells you on every answer whether the number is exact or an estimate.

- IT with a professional email address18,353,935
- IT with all five fields present1,703,941
Why a second filter changes the answer. The August 2026 cube holds one dimension at a time, so a count for IT on its own is read straight out of it and is exact. Combine IT with a second dimension and the cube has no such cell — the explorer estimates it, shows the ceiling it cannot exceed, and labels it an estimate rather than passing it off as a measured number.
