en.Wedoany.com Reported - Brazilian startup Avisa App launched a WhatsApp bulk messaging service based on Meta's official API at Web Summit Rio, held from June 8 to 11 in Rio de Janeiro, marking the company's strategic shift from an automated collection tool to an enterprise-grade WhatsApp marketing infrastructure.
Headquartered in Pareci Novo, Rio Grande do Sul, the company is one of 1,572 startups exhibiting at this record-breaking Web Summit Rio. The event attracted 40,287 participants and 688 accredited investors from over 100 countries. For Avisa App, Web Summit Rio served as the public launchpad for its new WhatsApp marketing service built on Meta's official API, solidifying its strategic positioning: no longer just a collection tool, but a broader player in business communication via WhatsApp.
The company began operations in 2025, initially as a lightweight layer for WhatsApp message automation, focusing on collection sequences and financial reminders. In February 2026, Avisa App was approved as a Meta official Technology Provider (Tech Provider), a qualification that paved the way for direct enterprise-level use of the WhatsApp Business official API. The new bulk messaging module showcased in Rio transforms this infrastructure into a WhatsApp marketing service for businesses looking to run structured campaigns on the country's most popular channel.
According to Serasa's Default Map (Mapa da Inadimplência), as of February, 81.7 million Brazilians were in default, equivalent to 49.9% of the adult population. Meanwhile, WhatsApp remains the most used messaging app in Brazil, with a penetration rate of nearly 98% among similar app users and an average open rate of approximately 98%, compared to around 20% for traditional email. This contrast supports Avisa App's argument: if nearly half of Brazilian adults face credit constraints, and WhatsApp is the channel with the highest open rate, then collections, customer service, and marketing converge in the same place. The new bulk messaging service is precisely positioned here, offering businesses an infrastructure to run marketing campaigns, utility notifications, and collection flows from the same official number.
Avisa App's new bulk messaging feature operates entirely on Meta's official API. Messages are sent from the business's verified number, with Meta's authentication badge when applicable, rather than from unofficial instances prone to blocking; marketing and utility templates require pre-approval by Meta, ensuring predictable delivery rates and correct categorization, which determines the cost per conversation in Brazil in 2026; contact lists can be segmented within the platform, with opt-in controls and delivery and read reports. The goal is to integrate into a single panel the collection sequences, transactional utility messages, and commercial marketing campaigns that businesses currently handle in separate layers.
The Avisa App platform already offers plug-and-play integrations with Asaas, Conta Azul, Efi Bank, and OpenPix, four native connections covering most financial processes for Brazilian SMEs. The platform architecture allows for adding new integrations based on each client's tech stack, particularly in ERP, CRM, and regional gateways. This open platform design enables scaling to mid-sized and large enterprises without rewriting the product.
Participating in Web Summit Rio marks the beginning of Avisa App publicly positioning itself as a WhatsApp marketing infrastructure based on the official API, rather than just a collection tool. This interpretation aligns with the ecosystem: the channel has become a firmly established part of Brazilian consumers' digital lives, and the challenge for businesses is no longer just being on WhatsApp, but operating it with governance, scale, and official messaging. The new service is now available, with its onboarding process leveraging Avisa App's existing integrations and leaving room for additional custom connections based on each client's needs.
