Weni

What Weni does

Weni Plataforma e Tecnologia Ltda., operating as "Weni by VTEX" since its September 2024 acquisition by VTEX, is a Brazilian AI company that builds multi-agent conversational platforms for retail customer service. The company's core product is a set of specialized autonomous agents — Order Status, Returns and Exchanges, and Concierge — that automate post-sales workflows primarily over WhatsApp, with multimodal support for text, audio, and image inputs. These agents are developed and orchestrated through Agent Builder 2.0, which includes a per-client Knowledge Base, tone-of-voice configuration, and business-rule controls, and are made available as pre-built templates via the Agent Gallery.

Underlying the agents is Weni Brain, a generative AI engine that integrates large language models with procedural flows, anchored by the proprietary Golfinho and Boto language models trained specifically for Brazilian Portuguese and supplemented by GPT-4-Turbo for multilingual coverage. WeniGPT provides an additional generative layer that grounds responses in each client's proprietary knowledge base. The platform exposes REST APIs and a command-line developer tool (Weni CLI), and integrates natively with VTEX plus 30+ ecosystem partners including Correios, Intelipost, Troque Commerce, and Meta's WhatsApp Business API.

Weni monetizes through enterprise SaaS subscriptions sold via direct sales, the VTEX App Store, and a self-serve platform at dash.weni.ai, targeting primarily retail e-commerce customers across Brazil, Mexico, Argentina, and (post-acquisition) the United States. Named customers include Cencosud, Midea, Grupo Líder, CVLB Group, Osklen, Rossetti Deportes, and Positiv.a, with published outcomes including 92% automated resolution, 96% automation with 20% cost reduction at CVLB, a 41% AOV lift at Midea, and 1,524% ROI in 30 days for a Mexican furniture retailer. All five co-founders — Leandro Neves, John Cordeiro, Daniel Amaral, Bruno Amaral, and Rinaldo Amaral — remain with the company as VTEX executives following the acquisition.

Core offering

Weni by VTEX sells a multi-agent AI platform that automates retail customer service and conversational commerce, primarily over WhatsApp. The core offering consists of specialized autonomous agents (Order Status, Returns and Exchanges, Concierge) orchestrated through Agent Builder 2.0 and powered by the Weni Brain generative AI engine with proprietary Brazilian Portuguese language models (Golfinho and Boto). Customers — primarily retail brands — buy subscription access to deploy these agents for post-sales automation, cart recovery, returns, and personalized recommendations, with native integrations into VTEX, logistics providers, and returns systems.

Product overview

Weni by VTEX is a modular AI-powered customer service platform for retail, centered on specialized autonomous agents that handle post-sale and engagement workflows. The product portfolio consists of three core AI Agents (Order Status Agent, Returns and Exchanges Agent, and Concierge Agent) augmented by the Agent Builder 2.0 platform for developing and orchestrating multi-agent teams, the Agent Gallery of pre-built templates, and a Knowledge Base for rule alignment. Weni's AI engines — Weni Brain (with proprietary Golfinho and Boto Portuguese models and GPT-4-Turbo multilingual support) and WeniGPT (custom generative AI on exclusive per-client knowledge bases) — power the agents' intelligence. The Weni CLI enables developers to go beyond visual flows. The Interactive Journey module covers the full retail journey from pre-purchase (catalog search, abandoned cart, one-click checkout, marketing campaigns) through post-purchase. All agents operate primarily over WhatsApp, with native integrations into VTEX e-commerce, logistics providers (Correios, Intelipost, All iPost, Cadê Meu Pedido), and returns systems (Troque Commerce, AfterSales).
