Hyperbound is the Revenue Activation Platform. Score real calls, practice with AI roleplays, and let Kota agents close the loop on every deal. Backed by Peak XV and Y Combinator.
About the role
We work with high trust and real autonomy. You’ll have the context to make decisions, the freedom to choose your approach. We trust you to spot problems, challenge assumptions, and move things forward without waiting for step-by-step direction.
What they're looking for
- 3+ years of full-stack engineering experience in React, Node.js, TypeScript environments. You’ve shipped production features across the frontend, backend, and database—and owned what happens after launch
- Fluency with AI-assisted design and development. You use AI tools to prototype, build, and debug faster, with the judgment to evaluate their output and take responsibility for the code you ship
- An instinct for building AI-native products. You see where AI can meaningfully improve a workflow and think through how the experience should handle uncertainty, latency, and mistakes
- Comfort with ambiguity and ownership. You can turn an open-ended problem into a clear approach, make thoughtful tradeoffs, and carry it through to a working product without needing a detailed spec
- A bias toward shipping and learning. You know how to scope a useful first version, get it into customers’ hands, and improve it based on feedback
- Strong technical foundations , developed through a bachelor’s or master’s degree in Computer Science or a related field, or equivalent coursework and practical experience
More about this role
Deals are messy. Multiple stakeholders, hours of calls, and endless emails. At Hyperbound, we're building the AI Agent that will help sales teams untangle that mess.
Hyperbound is the Revenue Activation Platform: an agentic OS for sales that connects what happens to what should happen next.
We came out of YC S23 and went viral with Voice Agents that reps could call to put their skills to the test. Today, we’re building AI that understands sales conversations, coaches in real time, reasons across deals, and takes action to move them forward.
We are trusted by companies like LinkedIn, Amazon, Bloomberg, Supabase, Monday.com , Notion, and Vanta. We raised a $15M Series A in October 2025, grew ARR 5× over the past year, and are growing nearly 20% month over month.
We’re former YC founders and founding engineers. We like hard problems, strong opinions, and getting something into customers’ hands while the idea is still fresh.
