Milan-based AI public tender platform Cato has raised a €6 million Seed round led by Keen Venture Partners — the article reports €6M, not $6.5M, and describes the company as Cato, not CATO Networks — marking a follow-on round just months after a €1.6 million pre-Seed led by Italian Founders Fund. The Seed included returning investors Vento, Heartfelt, Moonstone, BHeroes, Alecla7 and Nova Venture, plus new angel investors including the founders of Lexroom, Sibill and Pillar. The article discloses no specific client count, revenue, pipeline or employee numbers, only that the 2025-founded company by Andrea Zorzetto and Matteo Bossolini has "managed thousands of tenders" and tracks more than 27,000 sources, and does not detail planned use of funds or expansion plans beyond its positioning in Italy's €309 billion public tender market in 2025.
