We're in-person, 5 days a week. 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 built be the reason a customer signs an $800K contract. That kind of thing either sounds like your dream or your nightmare.
If it's the former, that's the job. If you'd rather have more structure and a clearer lane, this probably isn't it.
Still here? Good.
Hyperbound is the Revenue Activation Platform; An agentic OS for sales that closes the loop between behavior, coaching, and execution. Not a tool that watches what happened. A system that changes what happens next and literally changes the structure of our customer sales orgs in the process.
IBM, LinkedIn, Bloomberg, Supabase, Monday.com, Notion, and Vanta are just a few of our customers. They renew. They expand. We just 5xed in ARR the last year and are growing nearly 20% month over month. We just raised a $15M Series A, and had a $1M new ARR week to end the last quarter. 50% of everything we've ever shipped as a company happened in the last three months.
Key Responsibilities:
My cofounder and I are both engineers. This is an engineer-driven company, and that shapes everything, how we prioritize, how we debate, what we respect.
The people we've hired are a little crazy. Ex-YC founders who wanted to build again. A founder who competed against us, decided we were doing it better, and joined. Engineers who walked away from comfortable jobs because they had something to prove. Whether it was to themselves, to someone else, or sometimes both, I see it every day. These people genuinely inspire myself and Sriharsha ever day, and they run like hell.
After our Series A, we took the whole team to Bali. We work hard and we celebrate properly.
Our team hanging out on our office couch (it’s crazy but we hired 10 more people after this photo we took just 2 months ago):
And our team right after we raised our series A in Bali:
You deploy your own code. When something breaks, you fix the thing that caused it. When you see an architectural problem, you own the fix end to end. We don't have a lot of process protecting you from responsibility OR impact. If I had to some what makes a Hypernaut, this would be it in one word.
The equity reflects that. We believe in making early employees meaningfully wealthy, and there are real secondary opportunities as we grow.
— Atul and Sriharsha
