The Chilean startup Kapso raised a round of US$1.4 million to accelerate the development of its platform that allows any developer to integrate the official WhatsApp Business API into their products. The company was founded by Andrés Matte, a former partner at Platanus Ventures, who built the product practically alone during its first years.
With this investment, Kapso seeks to consolidate itself as the infrastructure used by startups and companies to build customer service, sales and artificial intelligence agent experiences on WhatsApp, one of the main communication channels in Latin America.
From a project built by a founder to a community of 28,000 developers
Kapso was born with a simple premise: to make integrating WhatsApp a quick and accessible process for any development team. The platform offers an API, a CLI, and a no-code visual builder that allows you to connect messages, templates, flows, and AI agents in minutes.
Growth came without external investment. Currently, more than 28,000 developers use the platform and the company claims that today it processes more messages in a single hour than during all of August 2025.
A round driven by users who ended up investing
One of the most striking aspects of the uprising is that several investors first learned about Kapso as users of the product. After testing the platform, they decided to participate in the round, which according to Andrés Matte was closed even without a traditional pitch deck.
Investors include Norte Ventures, Latitud, Newtopia, Platanus, Hypersphere, Semilla Ventures and Chile Ventures funds.
Also participating were prominent angel investors such as Matías Woloski and Damián Schenkelman, co-founders of Auth0; Juan Pablo Cuevas, co-founder of Cornershop; and David de Picciotto, founder of Pledge.
The commitment to the infrastructure behind AI agents in WhatsApp
Kapso comes at a time when more and more startups are building AI assistants and agents on top of WhatsApp to automate sales, support and operations.
Instead of developing these applications directly, the startup is committed to becoming the technological layer that allows other teams to build them. Its proposal competes with global solutions such as Twilio, offering an integration focused on simplicity and costs for developers in the region.
With more than 3 billion WhatsApp users in the world and a growing adoption of AI agents within the application, Kapso seeks to position itself as a key piece of that infrastructure from Latin America.
