About the role
We are looking for a Founding Account Executive with 4+ years of experience selling technical B2B products to help turn growing demand into revenue and build a repeatable sales motion at Moss (YC F25), the retrieval runtime powering real-time AI agents. You'll work directly with the Founder & CEO, own deals end-to-end, and play a critical role in shaping how the company sells as it scales.
What will you be doing?
- Own the full sales cycle from prospecting through close — including discovery, demos, pricing, negotiations, and procurement
- Build pipeline through targeted outbound, inbound qualification, and signals from developer/self-serve adoption
- Partner with engineering to run POCs, establish success criteria, and move evaluations toward buying decisions
- Expand accounts from initial use cases into more agents, workloads, and end customers
- Build and refine the sales playbook — improving qualification, messaging, and deal execution based on what you learn
Key Requirements
- Proven track record selling technical B2B products (developer tools, APIs, AI infrastructure, or consumption-based products preferred)
- Ability to personally source and close deals, including navigating technical evaluations and multiple stakeholders
- Comfortable engaging developers, engineering leaders, and business buyers with equal credibility
- Strong deal structure discipline — clear qualification, stakeholder mapping, agreed next steps, and realistic close plans
- Thrives in early-stage environments where you're building the sales process while carrying a quota
About Moss
Moss helps AI assistants find information instantly instead of making you wait. When you talk to an AI voice agent, it has to look something up before it can answer, and that lookup is usually what causes the awkward pause. Moss removes the pause by keeping the information right where the assistant is running, on your phone or in your browser, rather than fetching it from a server somewhere else. It is sold to the engineering teams building voice assistants and AI helpers, and it slots into the tools those teams already use.
