WhatsApp growth strategy for driving more app installs

You are a product manager at Meta working on WhatsApp, and the goal you have been given is more WhatsApp downloads. How would you grow that number? Explain which sources of new downloads you would go after, what you would build or change, and how you would measure the result. ```hint Who still needs it People install a messaging app when someone they need to reach is already on it. Ask where that pull is weak today, and which current users have a reason to bring someone new in. ``` ### Clarifying Questions - Does a download mean a first-time install by someone new to WhatsApp, or do reinstalls, installs on a new phone and the desktop app count too? - Is the goal global, or focused on countries where another messaging app is the default? - Is the real objective downloads themselves, or new people who register and keep using WhatsApp? - Are paid marketing and promotion inside other Meta apps on the table? ### What a Strong Answer Covers - A precise definition of the download metric and how it relates to new active users - Where new downloads can still come from: markets where WhatsApp is already the default versus markets where another app leads, plus new phones and extra devices - Growth levers built on WhatsApp's network effects, such as invites, groups and businesses, and on removing install and sign-up friction, with a prioritized choice - Metrics and guardrails against spammy invites, low-quality installs and privacy harm ### Follow-up Questions - Downloads go up, but the number of newly registered users stays flat. What would you investigate? - In a country where another messaging app is the default, why would someone install WhatsApp as well, and how would you win them? - How would you get more invites from existing users without making them feel like spam?
