Rintin: USD 6.2 million led by Cometa for B2B supply to small merchants

On 4 August 2026 Rintin announced a USD 6.2 million round led by Cometa, with Newtopia, Latin Leap, Amador Holdings and FJ Labs as co-investors. The company, founded by Argentines and with Mexico as its main market, operates a B2B platform that sells wholesale supply to small merchants and adds credit, logistics and artificial intelligence. It matters because it shows which metrics venture capital now requires to fund supply to traditional retail in Mexico.

The transaction

Rintin raised USD 6.2 million in an equity round led by Cometa. Newtopia, Latin Leap, Amador Holdings and FJ Labs joined, together with nine angels: Guillermo Rauch, Guibert Englebienne, Adolfo Babatz, Adalberto Flores, Josh Silverman, Matías Woloski, Agustín Soler, Mariano Battan and James Gutierrez. The valuation was not disclosed; neither were the instrument nor the stake sold.

The platform groups four layers for the small merchant: wholesale supply with more than 15,000 SKUs, inventory credit with more than USD 2 million disbursed, delivery logistics and artificial intelligence tools. At the announcement it reported more than 12,000 merchant buyers and 50 WhatsApp groups with more than 50,000 members. Mexico is the main market and Argentina the next, according to Mercado and Endeavor Argentina.

Value drivers

Credit as a retention mechanism. The company reports that retention among merchants with credit is up to 8x that of merchants without it. In our reading, that figure explains the round more than volume does: inventory credit turns an occasional purchase into a recurring cycle of supply and repayment.

A syndicate with one lead and nine angels. Cometa sets the price and a broad group of angels follows with smaller tickets. In our reading, the round was built on operator relationships rather than on a competitive process among funds, which usually translates into standard terms and an unpublished valuation.

Community before paid acquisition. 50 WhatsApp groups with more than 50,000 members against 12,000 active buyers: in our reading, the distribution channel is a low-acquisition-cost asset that a better-funded competitor cannot replicate with budget alone.

A modest ticket for a working-capital-intensive model. USD 6.2 million is an early round for a business with inventory, credit and logistics. In our reading, the syndicate is paying for evidence of unit economics and leaving scale to a later round or to debt.

What the market is signalling

For merchant-supply platforms in Mexico, the round arrives after Jüsto, an online supermarket with more than USD 300 million raised, suspended operations in December 2025 and was acquired by Grupo OMNi in January 2026 with a USD 100 million commitment. The contrast signals what venture capital funds today: not subsidised consumer volume, but the relationship with the merchant and the ability to charge it for credit and services.

For lenders, merchant credit is the line that can be funded separately. RappiPay launched in Colombia in May 2026 a loan line for its partner merchants with instalments deducted from sales, and Mercado Libre invested USD 1,730 million in its credit portfolio in a single quarter. In our reading, Rintin’s portfolio, today above USD 2 million, will be the asset that determines whether the next round is equity or debt.

G2’s reading for a mandate

A platform that sells, lends and delivers must prepare its round with three separate accounts: supply margin, expected loss and turnover of the credit book, and cost per delivery. In our reading, the lead investor in a Series A will pay for retention with credit only if the portfolio is audited and separable, because that is what will later allow it to be funded through a warehouse line instead of equity.
