You're In Business

Bubbo is a verified Spanish startup (Zaragoza) offering an AI-powered streaming guide. While the submission claims 'everyone' uses it, external verification confirms a more modest reality: ~10k-50k estimated downloads with 211 reviews on Google Play (2.9 stars) and €150k+ in pre-seed funding (Enisa/SantanderX). The project is active (updates in late 2025) and has pivoted toward tokenization (BBO token), but user reception is mixed due to performance issues. The score reflects a functional product with financial backing, heavily penalized for the submission's exaggerated traction claims.
