Wati.io, founded by CEO Ken Yeung in 2019, is a SaaS platform that leverages the WhatsApp Business API to help small and medium-sized businesses manage customer conversations more effectively, automating responses and enhancing engagement. Initially targeting large enterprises, Wati transitioned to MongoDB Atlas for scalability as its customer base grew to over 10,000 businesses in 165 countries, facilitating the management of millions of messages monthly. The platform's core features include automated customer engagement and sales management, with improved search capabilities through MongoDB Atlas Search, which enhances analytics and customer service efficiency. Looking forward, Wati plans to expand AI capabilities and integrate more communication channels like Instagram and Facebook. Concurrently, MongoDB is undergoing a leadership transition, with Dev Ittycheria retiring in November 2025, succeeded by CJ Desai, who brings extensive experience from ServiceNow and Cloudflare. This change aims to propel MongoDB into its next growth phase, capitalizing on its strengths in data-intensive applications amid the rise of AI, with Ittycheria remaining on the board to ensure a smooth transition.
