Launched Carrd to his own Twitter followers on March 7, 2016.

“I excitedly launched Carrd via”

The audience wasn't cold; it was the following he'd already built years earlier from his HTML5 UP/Pixelarity template work, which converted well into Carrd's first users.

“the followers I'd gained from that translated pretty well to Carrd”

A follower posted Carrd to Product Hunt on March 1, 2016 (before AJ planned to); it got featured on March 16, 2016, driving 1,000+ upvotes and the #1 spot in tech that day, plus thousands of new sites and hundreds of Pro upgrades.

“1000+ upvotes and the #1 spot in tech for that day”

AJ credits the surge specifically to the frictionless try-it-first experience: because no signup was required to start building, the Product Hunt traffic converted into thousands of new sites and users rather than bouncing at a signup wall.

“thanks in large part to that "no signup required" experience I was so set on implementing”

Years into the business, AJ describes Carrd's ongoing growth as running almost entirely on word of mouth, with no paid advertising or marketing spend.

“Carrd weirdly gets by entirely by word of mouth”

He frames it as a sequence: Twitter supplied the initial users, Product Hunt amplified that, and word of mouth carried growth from there.

“Twitter is basically what got the ball rolling”
