A Chilean startup that began as a solo founder project has closed a $1.4 million seed round to become the WhatsApp Business API infrastructure layer for developers across Latin America. Kapso, founded by Andrés Matte, a former partner at Platanus Ventures, attracted backing from investors who first encountered the company as customers of its developer tools.
The round drew participation from Norte Ventures, Latitud, Newtopia, Platanus, Hypersphere, Semilla Ventures, and Chile Ventures. Notable angel investors include Matías Woloski and Damián Schenkelman, co-founders of Auth0; Juan Pablo Cuevas, co-founder of Cornershop; and David de Picciotto, founder of Pledge, according to the original report.
Matte built the product largely alone during its early years. The company now serves more than 28,000 developers and processes more messages in a single hour than it handled during the entire month of August 2025. The funding will accelerate development of a platform that enables developers to integrate the official WhatsApp Business API into their products.
Kapso secures $1.4M to scale WhatsApp developer infrastructure across LATAM
Kapso offers an API, command-line interface, and no-code visual builder that connects messages, templates, workflows, and AI agents in minutes. The platform positions itself as an alternative to global solutions like Twilio, focusing on simplicity and cost efficiency for regional developers.
The startup reached this milestone without prior external investment. Several investors in the current round first used Kapso's tools before deciding to participate financially. The round closed without a traditional pitch deck, Matte noted in the report.
Before you start hiring
Check location, salary, and hiring fit
If you are moving from research to action, start with the market basics so your hiring plan is clearer.
Startups increasingly build AI assistants and agents on WhatsApp to automate sales, support, and operations. Rather than developing those applications directly, Kapso provides the technical layer that enables other teams to build them. With more than 3 billion WhatsApp users globally and growing adoption of AI agents within the app, the company aims to position itself as critical infrastructure from Latin America.
The Chilean tech startup ecosystem has produced notable exits including Cornershop's acquisition by Uber. Platanus, which backed Kapso and where Matte previously worked as a partner, runs an accelerator program that invests $200,000 for 7% equity in selected startups.
Why WhatsApp AI agents are reshaping developer hiring demand in Latin America
The shift toward WhatsApp-based automation creates specific talent requirements that differ from traditional software development roles. Companies building on Kapso's infrastructure need engineers who understand both conversational AI design and the constraints of messaging platforms, particularly around webhook processing, template management, and compliance with WhatsApp's business policies.
Developer platforms like Kapso reduce the barrier to entry for building WhatsApp integrations, but they also increase the volume of companies competing for engineers who can architect customer engagement systems at scale. The platform's growth to thousands of developers signals that AI infrastructure and developer platform roles growing across LATAM will require specialists in API design, serverless architecture, and real-time messaging systems.
Kapso's product includes serverless functions for webhook processing and WhatsApp Flow data endpoints, features that demand backend engineers comfortable with event-driven architectures. The company also offers tools designed for AI agents, including a command-line interface and integration with coding tools, which suggests demand for engineers who can build developer experiences that serve both human and machine users.
Compensation dynamics in the region may shift as infrastructure startups like Kapso scale. Seed-stage companies with significant developer traction often face pressure to hire senior engineers before revenue fully supports Silicon Valley-equivalent salaries. Kapso's ability to grow to 28,000 users before raising external capital suggests a lean operational model, but scaling the platform to support enterprise customers will likely require expanding engineering, DevOps, and customer success teams.
The investor composition signals workforce implications. Backing from founders who built Auth0, Cornershop, and other exits means Kapso has access to networks that can facilitate senior hires and provide guidance on scaling engineering organizations. Auth0's founders bring experience building developer-focused infrastructure.
Infrastructure plays to watch as WhatsApp automation accelerates in the region
Kapso competes in a market where Twilio has established global reach but where regional players can differentiate on pricing, localization, and support tailored to Latin American business practices. The company's focus on WhatsApp specifically, rather than multi-channel communication, represents a bet that the platform's dominance in the region justifies specialized tooling.
The startup's no-code builder and visual workflow tools suggest an expansion strategy beyond pure developer audiences toward product managers and operations teams. This broadens the potential customer base but also requires hiring for product education, technical writing, and customer success roles that can serve non-technical users.
As AI agent capabilities mature, infrastructure providers will need to address data residency, privacy compliance, and integration with enterprise systems. Kapso's roadmap will likely require specialists in security, compliance, and enterprise architecture as it moves upmarket.
The participation of crypto-focused investor Hypersphere Capital alongside traditional venture funds indicates that blockchain and Web3 applications may represent a use case for WhatsApp-based interfaces. This could create demand for engineers who bridge conversational AI and decentralized systems.
Kapso's ability to close a round based on product traction rather than investor presentations reflects a broader shift in early-stage funding toward usage metrics and developer adoption. For employers, this trend means that engineers with public GitHub contributions, open-source maintenance, or developer community engagement carry additional value when building infrastructure businesses in Latin America.
