Allocating Meta's messaging investment between WhatsApp and Messenger

Meta runs two messaging apps, WhatsApp and Messenger. As a product manager at Meta, explain how you would decide whether to put investment into WhatsApp or into Messenger. ```hint Compare roles before sizes Work out what each app is for, where it leads and who depends on it before comparing user counts. The decision is about where additional spending earns the most, which is not always the bigger app. ``` ### Clarifying Questions - Is this an either/or choice, or a question of how to split a fixed budget or headcount between the two apps? - What should the investment serve: revenue, user growth, engagement across Meta's apps, or strategic position against other messaging apps? - Over what time frame are the returns judged: the next year, or several years out? - Is work that keeps both apps secure, reliable and compliant already funded separately, outside this decision? ### What a Strong Answer Covers - A stated investment goal and the time horizon used to judge it - An accurate comparison of the two apps' roles: audiences and regions, links to Facebook and Marketplace, and how each makes or could make money - Marginal return on extra investment in each app, weighed against risks such as regulation, privacy commitments and competition - A clear recommendation, either a choice or a split, with the reasoning behind it - Metrics and checkpoints that would change the allocation later ### Follow-up Questions - Suppose Messenger's usage is shrinking in most markets. Would you cut its investment to the minimum, and what would you protect? - WhatsApp chats are end-to-end encrypted. How does that limit monetization ideas, and which ones still work? - If regulators required both apps to exchange messages with rival messaging apps, how would that change your allocation?
