When you export a search, its plants are also saved as a list named after the search. Each plant has a status and a note, so the list is where you follow up.
A weekly summary by email says who is left to contact on each list. It is off until you turn it on, and one click stops it.
When a registry is loaded again, the app shows which plants are new on a saved search and which plants on a list changed.
Taiwan is in the app
Manufacturers in Taiwan are now in the app search, read from the business tax registration file of the Fiscal Information Agency, Ministry of Finance. It is the first country outside Latin America.
Names and addresses are in Traditional Chinese, as the registry writes them. Activity names are translated. The file has no phone, email, website or coordinates, and it gives registered capital, not staff.
Only legal entities are loaded. The coverage page shows the source, its edition and its licence.
List status, saved comparisons, several regions and feedback
Each plant on a list has a status: to contact, contacted, replied or rejected. A comparison can be saved under a name, reopened and shared as a link.
The state or region filter takes several regions at once, with two ready sets for Mexico: the border states and the Bajío.
A record shows more facts where the registry holds them: secondary activities, share capital, legal form, programme and exporter lists, distances to the nearest port, airport and border crossing, and similar plants nearby with the count the linked search returns.
Send feedback from any page, or say that a record is wrong in one tap. A new page lists what we are building next, and accounts vote on it in the app.
Launch offer, and one list on Free
Launch offer: subscribe by November 30, 2026 and Pro costs 30% less for the first 12 months, $34.30 a month on the monthly plan. It is applied at checkout, with no code.
After the trial, a Free account keeps one list: its oldest, up to 25 plants. You can still save plants to it and edit notes and status. Contacts, export and more lists are part of Pro.
Product tour, features page and statistics
The home page has a product tour: search, a record, a list, compare and the supplier brief, shown as an example recorded from the live search.
A features page says what each part does and what is in Free and in Pro. Three pages speak to sourcing, supplier quality and research teams.
Statistics pages give the number of manufacturers by country, region and sector, with the registry, its edition and a CSV file to download. A methodology page says how each count is made.
Without an account, a search now shows the count, the split by country and industry, and a preview of 3 rows.
Mexico and Brazil: establishments of every size
Mexico now holds manufacturing establishments of every size, where it held only those with 6 or more staff. Rows with no name are left out, and so are units with 10 or fewer staff named only after a person.
Brazil now includes micro companies. Establishments of sole proprietors are still left out.
The count on every page comes from the data file. The coverage page gives the rows loaded for each country and the rule behind them.
A redesigned record, compare, the supplier brief and a first-contact message
The record now leads with the answer: what the plant makes, where it is, and how to reach it. The gaps moved to the end, each with what to ask the plant for.
Compare puts up to five plants side by side with the same facts, marks the rows that differ, and exports to CSV.
The supplier brief prints one record on one or two pages, every fact with its source and date. The first-contact message fills a fixed template in Spanish or Portuguese, with English beside it.
The Testigo app: a first-run guide and clearer plan screens
Accounts now live in the Testigo app at app.testigomexico.com, with a sidebar, light and dark themes and the record beside the results.
A new account gets a three-step guide: search, open a record, save a plant to a list.
The app says where your plan stands: the days left in the trial, what Free keeps when the trial ends, and how to fix a payment.
Install Testigo on your phone
Testigo can be added to the home screen on Android and on iPhone, from the browser menu.
It opens in its own window, with shortcuts to Search, Lists and Check a supplier.
Without a connection it shows a short offline page. Search and your account still need the network.
Pro plan opens
Pro costs $49 a month, or $468 a year. Prices are in US dollars.
Every new account starts with 14 days of Pro, with no card.
Free stays: search, the count and the first 10 results of each search.
Check a supplier by tax ID
Enter a country and a tax ID. Testigo shows every official list it holds for that country that names it.
It works for Mexico, Brazil, Colombia and Argentina, and is part of Pro.
An empty result is not a clean bill of health. The page names each list read and its edition.
Contact form, terms of service and this page
A contact form for questions, for a record that is wrong, and for requests to correct or remove a company record.
Terms of service, written in plain language.
This page lists every change to the product, with its date. The Bajío census pages from September are retired, and their addresses lead to the Mexico guide.
Guides in nine languages
Every guide, the glossary and How it works can now be read in nine languages.
Each of the nine countries has a guide to its public registry: who publishes it, what it holds and what it leaves out.
Testigo’s own checks on every record
A record now shows three checks run by Testigo, each with its date: website responded, certificates named on the plant’s own website, and email domain accepts mail.
New search filters: region, plant or company, a certificate named, and the Mexican IMMEX and PROSEC programmes.
Where a registry gives no coordinates, the record shows an approximate position taken from the place name.
A directory by country and activity
One page per country and manufacturing activity, with the count, the source and its edition.
The directory is in English for every country, in Spanish for the Spanish-speaking countries and in Portuguese for Brazil.
The privacy notice and the About page can now be read in nine languages.
Nine countries live
Testigo is now a search over manufacturing plants in nine Latin American countries, each read from its official public registry.
Search is open to anyone. An account adds lists, saved searches and export.
The coverage page lists every source, with its publisher, its edition and what is missing.
