The note was put together by executives at tbh, the once-popular viral polling app that was bought and recently shut down by Facebook. It isn't clear when the memo was sent.
Tbh was popular with young people and, according to BuzzFeed, its leadership shared lessons in how it managed to target teen users. Facebook, incidentally, happens to be losing teen users from its main app to Instagram and Snapchat.
Even though Facebook shuttered tbh for "low usage," it did provide learnings for Facebook's own polling tools, according to BuzzFeed. And, it appears, it provided a playbook for targeting younger users.
One reason tbh was so successful in attracting young users to its app, its founders wrote in the memo, was because it used growth-hacking methods.
Rather than relying on a blowout press campaign, tbh used Instagram to create a sense of mystery. This, they said, was "a novel method."
"Our team obsessed with finding ways to get individual high schools to adopt a product simultaneously," they wrote in the memo. "We designed a novel method that was reproducible, albeit non-scalable."
They explained how tbh would create dedicated, private Instagram accounts that targeted users of a particular school.
Taking advantage of the fact that many high schoolers list their school on their Instagram profiles, tbh found a school's location page, then followed any accounts that included that school's name. The tbh account would be blank, except for a call-to-action inviting people to stay tuned for its future app.
According to BuzzFeed, young users would be curious and follow the account back.
Once tbh had collated enough follow requests for its private account, it would wait till 4PM, when schools typically finish, known as "The Golden Launch Hour" internally at tbh.
It would then add the App Store URL for its main app to its private Instagram profile and set the account public, which notified teen users that their follow request had been accepted. They would often follow the link and download the app and like magic, tbh essentially went viral among teens.
It worked too. Tbh was downloaded 5 million times in nine weeks and was acquired by Facebook just three months after launch. Soon after the deal, however, tbh plummeted down the App Store ranking.
The note's authors wrote that these kinds of hacky tactics "are certainly too 'scrappy' for a big company," but added that Facebook could learn from their methods. That might include sending out push notifications instead of download links, "to ensure critical mass" for a new launch.
Facebook declined to comment.
