Sales is the most expensive department - more than engineering, HR, marketing, and more, in large companies.Problem: As businesses grow larger, their sales spend grows disproportionately. Why? Sales—especially outbound—is still human-driven: it's subjective, hard to measure, and doesn't scale like code. This is exactly the kind of problem agents are built to solve.Opportunity: With the advent of recent tech like agentic AI, large language models, vector DBs, and more - future sales is human x machine. Our agent, Selix, has already seen a lot of success.Timing: Right now, we are in the dot-com boom of AI Agents. The agents we build help solve a businesses's #1 problem: how to grow revenue. We use Chained LLM thinking and start of the art GTM tools to help companies grow.Want to learn more?
