AdOpt in Brazil, in numbers
3,534 companies in the LatSouth Brazil Technographics file run AdOpt on their public homepage: 0.9% of the 379,761 companies whose verified website shows at least one identifiable technology. The largest share is in São Paulo, and the leading sector is wholesale and retail trade; repair of motor vehicles. By company size: Larger (DEMAIS) 1,755, Micro (ME) 1,079, Small (EPP) 696, null 4.
How it is detected: AdOpt was seen through a script the page loads, a stylesheet, iframe or link URL. The scan reads the homepage once, without running JavaScript, so tools that only load inside a tag manager, at checkout or after a click are not counted: treat the number as a floor, not a census.
Each company row in the file carries the CNPJ, legal and trade name, CNAE in English, size, state and city, the verified website and the registry contacts sold in the other Brazil files, plus every technology id, its category, the evidence type and the scan dates.
Seen together with AdOpt most often: WhatsApp click-to-chat (58.4%), WordPress (55.1%), Google Tag Manager (50.4%), Elementor (WordPress page builder) (35.8%), Google Analytics 4 (gtag) (32.3%), Cloudflare (21.6%), Meta Pixel (19.1%), RD Station (15.4%).

Questions
How does LatSouth know a company uses AdOpt?
Its own homepage shows AdOpt through a script the page loads, a stylesheet, iframe or link URL. The fingerprint table is versioned and tested per signature; only the technology id and the evidence type are kept.
Does the file include contacts?
Yes, the company-level contacts sold in the other Brazil files: the registered phone with an accountant flag, the registered e-mail only when it is a role mailbox on the company's own domain, and the verified website. No personal data.
How fresh is it?
The homepages were scanned on 2026-11-03; the company columns come from the Receita Federal release 2026-10-10. A refresh is available on request.
Company data only. Counts are of companies (head-office CNPJ), never of people. LatSouthBot reads each verified homepage once, after its robots.txt, without logging in, filling forms or running JavaScript, and keeps only the technology ids and how they were seen, never the page text. A site that disallows LatSouthBot is not scanned; to opt out, add it to robots.txt or write to hello@latsouth.com. About LatSouthBot · Compliance.
