Industry Mainstay

Bookline is a verified, high-traction Series A startup (approx. €3.5M funding, ~60 employees) providing AI voice assistants to over 1,500 hospitality venues across Spain, USA, and Colombia. While the submission data itself was poor (claiming only 150 restaurants and providing vague answers), independent verification confirms significant market presence, managing millions of calls annually. The project demonstrates high real-world utility and is positioned well in the current AI voice agent market. The score reflects the strong underlying business reality despite the low-quality submission effort.
