Hyperbound

Hyperbound builds a Revenue Activation Platform, described as an agentic operating system for sales teams that links behaviour, coaching and execution. Founded in 2023 and part of the Y Combinator Summer 2023 batch, the company applies AI agents, conversational AI and LLM-based simulation to enterprise sales training, using natural language processing and machine learning to model sales conversations and measure performance.

The platform comprises three products. Hyperbound Practice is an AI-powered sales roleplay product in which teams rehearse against simulated buyers; Hyperbound Perform measures and scales top-performer behaviours across a sales organisation; and Kota is the third core product in the suite. The technical work spans agent design, conversational modelling and evaluation of unstructured dialogue at scale.

Hyperbound raised an $18.3m Series A led by Peak XV Partners and reports quintupling its ARR over the past year. Customers include Autodesk, IBM, LinkedIn, Bloomberg, Monday.com, Notion, Vanta, Supabase and G2. The company ships new features weekly, closes feedback loops directly with customers and describes a culture of hands-on ownership, with founders closely involved in building and iterating on the product.
