About Hyperbound Hyperbound (YC S23) is the Revenue Activation Platform, an agentic OS for sales that closes the loop between behavior, coaching, and execution. We're a system that changes what happens next, and we're reshaping the structure of our customers' sales orgs in the process. As the inventors of AI sales roleplay, we help enterprise sales teams practice, measure, and scale top-performer behaviors. IBM, LinkedIn, Bloomberg, Supabase, Monday.com , Notion, and Vanta are just a few of the companies that trust us. We 5x'd ARR last year and raised a $15M Series A led by Peak XV. Our team ships new features weekly and has close feedback loops with customers. The category is exploding, and we're pouring gas on the fire. The Role We move fast and expect a lot. You'll ship something the night before a customer demos it in front of 20,000 sales reps at their SKO. You'll watch a feature you build be the reason a customer signs an $800K contract.
