Who uses what — and who's switching
A company's stack leaks into public data: its email/DNS providers in DNS records, and the SaaS tools it names across its job postings. We snapshot both and diff them over time, so each page below shows the companies currently on a tool and the ones that just adopted or dropped it — a switching feed nobody else publishes.
