Frequently asked questions

What industry is BrainTool - Beyond Bookmarks in?
BrainTool - Beyond Bookmarks is a SaaS company in the Product-Led segment.
Is this profile actually verified, or just generated by AI?
The structured fields come from a hybrid pipeline. Facts (location, employee range, funding, tech stack) come from live web rendering plus Serper search across the company site, LinkedIn, press, and GitHub. Claude only picks the buckets: vertical, segment, growth signal. It never decides facts. Contact emails on full profiles pass an SMTP RCPT TO handshake at delivery time.
How is this different from a contact database?
Kustiq profiles one company at a time, live from the web when you ask. Tools like Apollo and ZoomInfo rent access to a 50M+ row pool that ages every quarter. Different shape, different price, and the freshness story is the opposite.
What does "track this profile" do?
Tracking saves BrainTool - Beyond Bookmarks to your free dashboard so you can re-run the full pipeline on it anytime. Free with a signed-in account: 3 profiles a week, no card.
Can the profiled company remove this page?
Any company in the Kustiq directory can request removal at /trust#removal. Removed profiles return 410 Gone and stay out of search.
How fresh is the data?
BrainTool - Beyond Bookmarks was last verified 26 days ago. The data refreshes when anyone re-runs the profile (the Re-run now button above does exactly that), and we run the SMTP handshake on contacts when you ask for them, not when we cached the row. The freshness card above the profile shows the exact relative date for the current visit.
