How would you invest $1B in WhatsApp?

Product Strategy Question: You're the PM for WhatsApp and you have $1B to invest. What would you do?

WhatsApp is a widely used cross-platform messaging app that enables users to communicate privately, securely, and seamlessly across borders. Owned by Meta Platforms Inc., WhatsApp allows users to send and receive text messages and voice notes, make HD voice and video calls, participate in group chats, and share rich media including images, documents, contacts, live locations, and stickers. More recently, it has expanded into payments, business messaging, and community features.

Available for free on Android, iOS, Windows, and macOS, WhatsApp’s appeal lies in its clean user experience, reliability, and strong privacy features — particularly its end-to-end encryption, which is enabled by default for all one-on-one and group conversations.

The platform has evolved from a simple chat app into a versatile communication tool, now supporting:

• WhatsApp Business (SMB engagement tools and APIs)

• Payments (UPI in India, Pix in Brazil)

• Communities (for larger, structured groups)

• Status updates (similar to Stories on Instagram/Snapchat)

• Companion devices (multi-device support without phone tethering)

WhatsApp is the world’s most popular messaging app, with over 2 billion monthly active users spread across more than 180 countries and localized into 60+ languages. Its user base is especially concentrated in high-growth markets such as India, Brazil, Indonesia, Nigeria, and Mexico.

Despite its massive scale and engagement, WhatsApp remains relatively under-monetized when compared to other Meta products like Instagram and Facebook. Its current revenue comes primarily through WhatsApp Business APIs used by mid-to-large enterprises for customer communication, and limited in-app payments services.

Competitors include Telegram, Signal, iMessage, WeChat, Viber, and LINE, each with varying strengths in encryption, openness, and ecosystem integration. In markets like China, WeChat dominates with a broader super-app model, while Telegram has gained traction globally due to its openness and cloud-based model.
