What Boom AI does

Boom reaches out to your customers before you lose them. We run proactive outbound conversations at scale: recovering churned users, re-engaging drop-offs, and protecting revenue you thought was gone. AI agents hold real conversations with your customers over SMS, email, WhatsApp, or phone, in their language, on the channel they actually answer. Every month, companies lose 5-15% of revenue to churn, and more walks out through abandoned signups and failed onboarding. The tools built to fix this don't work. Win-back emails get ignored. Cancel flows only catch people at the door. Hiring humans doesn't scale. Boom does the one thing that works: a real conversation. 1,000x the reach of manual outreach, and the customer can reply.

AI agents that recover lost revenue

What is your company going to make? Please describe your product and what it does or will do.

We build AI agents that proactively reach out to a company's customers via SMS, email, WhatsApp, or phone. Our product holds real, human-like conversations that recover churned users and re-engage drop-offs at scale. Unlike emails or cancel flows, our agents create actual dialogue and revive revenue that would otherwise be lost.

Where do you live now, and where would the company be based after YC?

We live and operate in San Francisco, CA, and plan to keep the company based here after YC.

Explain your decision regarding location.

San Francisco is the center of our network, talent pool, and potential customers in B2B SaaS and e-commerce. Staying here helps with recruiting and being close to early adopters.
