About Cluster

AI-native B2B startups plug our MCP & CLI into their agents to find prospects and build pipeline. We provide those agents what Claude and Codex are missing: 50+ domain-specific data integrations, unified outreach channels, and intent signals. We've hit $180K+ ARR in our first 2.5 months, growing 100% month over month, with hypergrowth customers like Parallel AI. Luis studied data science at MIT, published award-winning experimentation research, and scaled production ML systems to millions of users at Remitly. Enrique shipped production software for Bloomberg and the Department of War, and was the first engineering hire at a Series A startup.
