WeCapital's Data Tienda turns corner-shop notebooks into women's credit histories
Millions of Mexican women had no formal credit history, only shopkeepers' notebooks — WeCapital digitized the notebooks into official credit records.

What it had to solve
WeCapital, a Mexican lender focused on low-income women, faced a paradox: women repaid reliably, yet most could not get a loan because 83 percent of Mexican women had no credit history at all. The real barrier was documentation, not trustworthiness.
How it works
In Mexico, 83 percent of women had no credit history, which silently excluded them from bank loans for businesses or studies even though, as DDB Mexico's president put it, women pay better than men. The repayment evidence existed — in the notebooks of corner shops across Latin America, where shopkeepers recorded every item a customer took on weekly or monthly store credit.
WeCapital's Data Tienda made that informal ledger official. Women enrolled on the datatienda.mx platform, named five to ten shopkeepers who had trusted them, and gave consent for their records to be collected; shopkeepers confirmed each account online in under two minutes. The digitized records became real credit histories that worked at any financial institution, turning a behavior millions already performed into a doorway into banking.
The numbers followed: by December 2021 over a hundred women had received first microcredits, the service expanded from Mexico City to four more cities, and results grew past 10,300 credit histories, 2,300 microloans and 50,000 participating shop owners. The idea won the Creative Data Grand Prix at Cannes Lions 2022 and was named a 2024 Global Grand Effie winner in Marketing Innovation.
Why it lands
- It reframed the problem from access to credit to the missing proof of creditworthiness, which could actually be fixed.
- It formalized a repayment record women already had, so they did not have to change behavior to become visible to banks.
- The credit history belonged to the woman and worked at any institution, which made the tool a public good rather than a customer lock-in.
- It scaled through a channel that already existed — neighborhood shopkeepers — instead of requiring new financial infrastructure.
What it did
By the end of 2021 more than a hundred women had received their first microcredits and the scheme had expanded beyond Mexico City to Puebla, Guadalajara, Morelia and Monterrey. Reported results grew to more than 10,300 credit histories built, over 2,300 microloans granted for businesses and studies, data captured from more than 50,000 shop owners, and a 150 percent jump in applications.
What you can take
When the system cannot see someone's reliability, build the bridge that makes their existing behavior legible, rather than asking them to behave differently.
Since then
Data Tienda became WeCapital's signature innovation and a fixture of award judging: it took the Creative Data Grand Prix at Cannes Lions 2022, added the Glass Lion Grand Prix for culture-changing creativity the same year, and in April 2025 was named the 2024 Global Grand Effie winner for Marketing Innovation and Business Solutions. WeCapital said at least one other financial institution began using the platform, and DDB Mexico reported talks about taking the model to Guatemala and other Latin American countries, where the same notebook-based credit culture exists.
