Jack posted about the scheduling tool he had built for himself on X before it was a product. Despite a small following at the time, the post went viral and surfaced demand from strangers, which is what turned a personal tool into Post Bridge.

“I shared it on Twitter, and despite my lack of followers, it blew up”

Jack runs a documented daily routine of roughly one hour making and posting several short videos to TikTok and Instagram, without paid ads. He describes this as a repeatable, zero-ad-spend content habit rather than a one-off campaign.

“1 hours a day spent marketing my app (making + posting 6 videos)”

Jack's stated reasoning is that authentic, person-made content outperforms ads or produced/AI content. Separately, for Post Bridge specifically, he says his SaaS-related Twitter/TikTok following grew mostly as a result of the product's traction, not as the initial cause of it.

“the following grew mostly after the success, not before”
