Department:
Job Summary
HockeyStack is building the agent infrastructure for enterprise revenue. We spent five years building the only data architecture that preserves causality across the full revenue stack every interaction every signal in sequence. On top of that foundation we built Nex-lm a purpose-built AI engine that compiles natural language into deterministic agent workflows. The result is a platform that can extract the revenue blueprint from a companys data encode it into repeatable automations and execute it across sales marketing and customer success consistently at scale.
We are not building a dashboard tool with an AI feature. We are building the operating layer that replaces the human bottleneck in enterprise revenue organizations. This is a category being defined right now and we intend to own it.
We have raised $50M from Bessemer Venture Partners General Catalyst Y Combinator and others.
