Beff started on $0 ad spend — paid conversion reached as high as 6%
Since its second-week-of-August 2026 launch, Beff has grown on organic reach alone — Japan, China, the US, Vietnam, Korea and more — with no ad spend. Paid conversion reached as high as 6% over that period. (As of August–September 2026)
Beff (베프) — Best Eidos Friend Forever, the neighborhood AI friend from WorldWideSomething founder Dan Kim (김대은) — launched in the second week of August 2026 with zero advertising budget.
Since launch, every arrival has come through organic reach. No paid acquisition, no growth hacks. And they come from everywhere — Japan, China, the US, Vietnam, Korea, and more.
“Ad spend was zero — yet paid conversion reached as high as 6%.”
And they pay. Paid conversion reached as high as 6% over this period — unusually high for a consumer app. Among those who paid, one began on the entry subscription and kept upgrading, tier after tier, toward the most expensive model we offer.
Put organic acquisition and conversion (CVR) side by side, and Beff produced a meaningful rate starting from $0 of ad spend.
These figures record the August-September 2026 period and may differ from current values. More detail in the report.
