How Italy's Largest Marketplace Automated 99.5% of Moderation and Scaled Messaging Without Adding Headcount

Subito, Italy's largest re-commerce marketplace, transformed its buyer-seller messaging system by partnering with Stream, allowing them to scale their infrastructure without expanding their internal team. Faced with the complexity and resource demands of maintaining an in-house messaging system, Subito sought a solution that could handle marketplace-specific needs, such as offer negotiations and sophisticated moderation, while ensuring reliability and scalability across web, iOS, and Android platforms. The decision to collaborate with Stream resulted in a seamless migration of millions of conversations, enhanced fraud prevention, and improved transaction flows, ultimately allowing Subito to focus on its core business of enhancing user trust and transaction efficiency. The partnership with Stream not only optimized Subito's messaging infrastructure but also contributed to platform-wide improvements that benefited other Stream clients, demonstrating the value of strategic collaborations in managing complex technical systems.
