See which companies changed their technology, and when.
See which companies just switched off your competitor's product. Get trigger-based outbound signals with verified business emails, built on public data you can check.
“They run Microsoft 365” is a fact. “They moved off Google Workspace last month” is a reason to send an email today — and every row carries the prospect's whole tech stack, 17.3 technologies on average.
What a lead list looks like
Real rows from the July 2026 crawl — not a mockup. Every company below stopped running one technology and picked up another, confirmed across two consecutive crawls. Open any domain and check it yourself.

How teams use Ansafi
Three jobs, one dataset.
Find companies that just switched off your competitor's product and email them while the change is still fresh.
Push technology-change signals to Salesforce, HubSpot, Outreach or Salesloft by webhook. Every row carries the crawl month so your team can audit the trigger.
Watch a category month by month: who is winning installs, who is losing them, and which products they move between.
Technographics you can verify
Every signal you act on can be checked in about thirty seconds: open the prospect's site and look. Detection comes from HTTP Archive, an Internet Archive project backed by Google, Mozilla, Fastly and Akamai that loads millions of real sites in a real browser every month and publishes everything openly. Not job-ad inference, not a vendor black box. We are not the biggest dataset and we say so on the coverage page.
Works with your stack
Ansafi webhooks push technology-change signals into your CRM or sequence tool automatically. Every row carries the crawl month and the source URL, so your team can audit the trigger before anyone sends on it.
Delivered by webhook, CSV or REST API — see the API contract. Connect through any tool that accepts an inbound webhook.
