As of 30 October 2026 · refreshed daily · counts move as websites, DNS and career sites are re-read.
The website-and-DNS footprint is not comparable between a marketing suite and a CRM: BERT's script and mail records show on hundreds of thousands of small sites, GPT rarely leaves a trace outside its own apps. Compare on the job-posting numbers; use the footprint for reach.

Read from the source, not self-reported
Every number on this page can be traced to a page we crawled or a posting we read. Full methodology →
- Job postingsRead hourly from career sites. A tool counts when the employer's own text names it as the team's system; both tools can count for one company.
- Website and DNSScripts and embeds on the company's pages, plus SPF, DKIM, MX and CNAME records of its domain that point at the vendor.
- SegmentsCountry, size and industry from the company profile built from its website.
- Not a reviewNo ratings, prices or feature claims. For those, read the vendors.
BERT vs GPT: questions
Which is more used, BERT or GPT?
By companies naming it in their own job postings, GPT (796) over BERT (134). By website-and-DNS footprint, GPT (0 vs 0), because its scripts and mail records sit on many small company sites.
Who chooses BERT?
51% of BERT companies have 2 to 200 employees, against 48% for GPT. 25% of BERT companies have over 1,000 employees, against 29% for GPT.
Do companies run both?
126 companies name both in their postings, usually BERT in marketing and GPT in sales, or during a migration.
Where do these numbers come from?
From the employer's own text in job postings read hourly from career sites, and from scripts found on company websites in our crawl. No vendor data, no surveys.
