Beff (베프) — Best Eidos Friend Forever, the neighborhood AI friend from WorldWideSomething founder Dan Kim (김대은) — launched in the second week of August with zero advertising budget.

Since launch, 110 people have arrived on organic reach alone. No paid acquisition, no growth hacks. And they come from everywhere — Japan, China, the US, Vietnam, Korea, and more.

Zero ad spend — yet 3 of every 62 pay.

And they pay. Three of 62 have converted to paid — a 4.8% paid conversion, unusually high for a consumer app. One of them began on the entry subscription and has kept upgrading, tier after tier, toward the most expensive model we offer.

Put organic acquisition and conversion (CVR) side by side and the picture is clear: Beff is growing explosively — on $0 of ad spend.

The numbers are still early. But the direction is unmistakable. More detail in the next report.
