How usedby counts
A company counts once per tool, at its strongest proof: confirmed (a case study, a named testimonial, a press release or the company's own account), declared (the company told usedby), observed (a vendor logo wall or customers page) or signal (a job post). Counts cover the companies on usedby, never the whole market.
7 companies that sell software were left out, so a vendor is never counted as a user.
