The problem with supplier lists
You need plants that make a part or run a process in a country you do not know well. Directories show the companies that signed up or paid. Trade lists are old. Nobody says where a name came from or when it was last read.
Testigo starts from the other end. It loads every manufacturing row of the official registry, so the plant that never advertised is there too. Then it lets you search that record in your own words.
What Testigo gives a sourcing team
- Search by product, process, material or company, in English, Spanish or Portuguese.
- Filters by country, state or region, industry, segment and size, where the registry publishes them.
- A record for each plant with its activity code, place, size and the registry's own edition date.
- Contacts where the registry publishes them: phone, email and website. 541,618 of Brazil's 580,085 records carry at least one, and 309,246 of Mexico's 655,218.
- Export programmes on the record where a country publishes them, such as IMMEX and PROSEC in Mexico.
- Lists with notes and a status for each plant, CSV export, and a comparison of up to five plants.
- A first message drafted in the plant's language, and a supplier brief you can save as a PDF.
One search, start to finish
- Type the partSearch for wire harness. Testigo shows how many plants match and how they split by country and industry.
- Narrow itKeep Mexico, pick the states you can reach, and set a size. Mexico's registry counts staff. Brazil's publishes a size class by revenue, and Testigo says which is which.
- Read the recordsOpen each plant. Check the activity code, the place and what the registry holds. Lamps show a phone, an email, a website and coordinates when they are on the record.
- Build the shortlistSave the plants to a list, add a note to each, and compare the best five side by side.
- Make contact and file itDraft the first message in Spanish or Portuguese. Save the supplier brief for each plant you take forward.
What Testigo does not tell you
A registry records the activity of a plant, not each product it makes. A code such as SCIAN 336320 covers wire harnesses and other electrical parts for vehicles. The record says so, and the first conversation with the plant settles it.
- Certificates are not confirmed. A certificate the plant names on its own website is shown as a claim.
- Capacity, quality and financial health are in no registry. They need the plant's answer, an audit or a visit.
- Testigo has not visited any plant.
How each count is made is on the methodology page. The registries are listed on the coverage page.
Frequently asked questions
Can I find contract manufacturers on Testigo?
Yes, with a limit you should know. Registries record a plant's activity, not whether it takes contract work. Search by the process you need, such as plastic injection or metal stamping, and read the export programmes on the record. In Mexico, a company with an IMMEX programme manufactures for export. Ask the plant about contract work.
Which countries does the search cover?
Testigo covers 9 countries today: Mexico, Brazil, Argentina, Colombia, Peru, Chile, Ecuador, Paraguay and Uruguay. Mexico holds 655,218 plants and Brazil 580,085. Each country comes from its own official registry. The coverage page gives the source, the edition and the rows loaded for every one of them.
Do I get phone numbers and emails?
With Pro, yes, where the registry publishes them. In Brazil 541,618 records carry a phone or an email, and in Mexico 309,246 carry a phone, an email or a website. The registries of Argentina, Peru, Chile and Paraguay publish none. Free accounts see which contact fields a record holds, without the values.
How much does it cost?
An account is free and starts with 14 days of Pro, with no card. After the trial it stays on Free, with search, the count and the first 10 results of each search. Pro costs $49 a month or $468 a year and opens every result, contacts, lists and export.
