Boom AI is building the AI employee layer for e-commerce, deploying virtual agents that engage shoppers in personalized two-way conversations across SMS, email, WhatsApp, and phone. The premise is that most online stores still lose 99 percent of their traffic and a sizable share of post-purchase opportunities because no human team can follow up at the scale that conversion actually requires. Boom agents fill that gap by asking the right follow-up questions, recovering abandoned carts, reactivating lapsed customers, and turning otherwise missed messages into real revenue.
Unlike scripted chatbots, Boom agents are designed to feel like an attentive sales associate who remembers context, adapts tone to the brand, and operates at roughly a thousand times the throughput of a manual outreach team. The product positions itself as an AI growth team rather than a single channel tool, sitting between a brand storefront, CRM, and messaging stack and continuously optimizing for revenue recovered per conversation. Early traction is with direct-to-consumer brands looking to squeeze more lifetime value out of existing traffic without expanding their support or retention headcount.
The company was founded in 2025 by Juan Casian, Sergio Garcia, and Jose Toscano and is headquartered in San Francisco with a team of three. CEO Juan Casian previously founded Atrato, a YC W21 alum that became one of Latin America leading Buy Now Pay Later companies before being acquired, and the rest of the founding team also came out of Atrato in product and engineering roles. Boom AI is part of Y Combinator F25 batch and is competing in the increasingly crowded AI sales automation category with a focus on real conversations rather than mass outbound blasts.
