Vibe-Kanban Shuts Down Live Onstage at AIE Europe with 30K MAU

Vibe-kanban's CEO announced the product's shutdown live onstage at the AI Engineer (AIE) Europe conference despite the tool having 30,000 monthly active users. The stated reason: "Everyone who is making money is doing 2 things: selling to enterprise, and reselling tokens. We were doing neither." The project ran from 2021 to 2025 before being open-sourced at the moment of shutdown — an unusually transparent close of a product with meaningful user adoption.

Why It Matters

Vibe-kanban's failure formula — consumer traction without enterprise revenue and without token-resale margin — is the defining AI startup failure mode of 2025-2026, validating that user numbers without B2B contract flow are not a business.
