Rintin's WhatsApp-first B2B bet for Mexico's informal shops: $6.2M raised
Mexico B2B wholesale marketplace for informal micro-merchants: 50,000+ WhatsApp community, 12,000+ buyers, US$2M+ credit, US$6.2M Cometa-led round.
Rintin
What the business is
Rintin is a Mexico B2B wholesale marketplace that connects micro and small merchants directly with verified manufacturers and importers: 15,000+ SKUs, door delivery, cash-on-delivery, AI-scored embedded credit, WhatsApp ordering, and simple phone tools for inventory, sales and expenses.
Starting capital：US$6.2M early-stage round announced around 2026-07-30, led by Mexican VC Cometa with Newtopia VC, Latin Leap, Amador Holdings, FJ Labs, and angels such as Guillermo Rauch (Vercel), Adolfo Babatz (Clip), Guibert Englebienne (Globant) and Adalberto Flores (Kueski).
How it started
Economist and Columbia MBA Quinto Van Peborgh met sneaker-brand founder Gastón Greco in New York before the pandemic. After an earlier, smaller marketplace for Mexico City boutiques and Instagram brands, they targeted street stalls; Greco moved to Oaxaca to study how small merchants really bought, and Rintin launched in Mexico in the early 2020s selling through WhatsApp groups with cash on delivery.
What happened
Growth came from community and operations, not ads: 50 WhatsApp groups of up to 1,000 people each with specialists, logistics that mixed FedEx and Estafeta with local couriers, and then embedded credit scored from purchase frequency, catalog activity and even photos of the shop. Retention reportedly rises roughly eight times once a merchant takes credit. In early 2026 Rintin joined Endeavor Argentina's ScaleUp program; around 2026-07-30 it closed a US$6.2M round led by Cometa to scale the marketplace, credit penetration, catalog and AI tools.
How it ended up
Live and scaling in Mexico as of 2026-09-02: the company plans to deepen credit, add categories such as cosmetics and electronics, and enter Colombia and Argentina; no exit or shutdown.
Background
Rintin is a Mexican B2B wholesale marketplace betting that informal micro-retailers - tienditas, market stalls and home resellers, most run by women - will stop making cash-and-carry trips to wholesale districts if they can order from verified manufacturers and importers on their phones. The platform carries more than 15,000 SKUs, delivers to the door, and layers on embedded credit scored from behavior rather than formal credit history.
Co-founders Quinto Van Peborgh, an Argentine economist with a Columbia MBA, and Gastón Greco, whose family ran a small shop in Chaco, Argentina, met in New York before the pandemic. After testing a boutique-oriented marketplace for Mexico City stores, they aimed at street vendors; Greco moved to Oaxaca to study how small merchants really bought, and Rintin launched in Mexico in the early 2020s.
Early operations were deliberately low-tech: cash-on-delivery to overcome fraud fear and community managers inside WhatsApp seller groups. By 2026 that community counted more than 50,000 active entrepreneurs across 50 groups, more than 12,000 merchants had bought, and over US$2 million in embedded credit had been disbursed; retention reportedly jumps about eight times once a merchant takes credit.
In early 2026 Rintin joined Endeavor Argentina's ScaleUp program, and around 2026-07-30 it closed a US$6.2M round led by Mexican VC Cometa with Newtopia VC, Latin Leap, Amador Holdings, FJ Labs and angels including founders of Vercel, Clip, Kueski, Globant and Auth0. The company's stated ambition is to become the bank of small Latin American entrepreneurs, with Colombia and Argentina as next markets.
What has to be true
- WhatsApp-first distribution met merchants where they already transacted, and the 50-group community became free acquisition, product validation and demand aggregation.
- Cash-on-delivery removed the fraud fear that blocked online wholesale for a segment that had been scammed before, making the first order safe enough to build habit.
- Behavioral underwriting - purchase frequency, catalog activity, shop photos - serves sellers with no formal history, and credit lifts retention about eightfold, the number that makes the model work.
- AI sales agents and catalog automation deliver personal follow-up and restock recommendations to thousands of merchants without matching headcount, keeping a logistics-heavy model lean.
What can be applied
In cash-first informal markets trust is the wedge: payment-on-delivery and WhatsApp groups de-risk the first order, then behavioral credit and AI agents compound that trust into lending.
Aftermath
As of 2026-09-02 Rintin continues to operate in Mexico and describes itself as an Endeavor Argentina ScaleUp company. Its roadmap is to expand the marketplace, raise credit penetration, add categories such as cosmetics and electronics, and enter Colombia and Argentina. Greco has described the Cometa-led round as a boost after an 'extreme optimization' period in a region where several logistics-heavy B2B marketplaces failed.
