Did you read the article? They're explicitly not focusing on user growth: "But while Facebook has long prided itself on the way its growth team has turned attracting new members into a science, Koum is equally proud of the fact that WhatsApp has not done so. Instead, all of its attention has gone into making the app as simple as possible to get started with—it doesn’t even require you to create a user name or passwor…
> Did you read the article? I did. > as simple as possible to get started with How is that not applying a focus on "user growth"? Just because you're not "growth hacking" or "using a a growth team" doesn't mean you are not implementing a strategy of growth of a user base. Adding a paywall or an advertisement would actively thwart the "simplicity of getting started", and thus halt user growth. My point still stands -…
Focusing on reach (ubiquity is an innovation). Focusing on operational efficiency (a low-cost tech company is an innovation).
The apocryphal stories about WhatsApp in support of the two above points are:
1) Supporting J2ME clients (ie: dumb-phones) ... connecting "poor people" in dumb-phone countries w/ "rich people" in smart-phone countries (for $0.99 app).
$0.99 / user * 25% of your userbase isn't enough revenue for most companies to be successful.
2) Be operationally efficient, reliable, and lean. How? By running like 10 erlang servers (targeting peak message transmission RATES, not all-time storage of messages or number of users)
This allowed them to _SCALE_ revenue because they're basically dividing by zero (Income v. Expenses) if they're extremely lean on number of employees, maintenance, and operations costs.
Therefore: it compares extremely well to Juicero as a counter-example.
