Why This Role

The frontier of AI is shifting from LLMs to physical AI, robotics, and voice-native agents. The labs building these next-generation systems need a new kind of training data: diverse, verified, human-in-the-loop, and at scale.

That is exactly what Kgen/Humyn Labs delivers. We are a dataset and AI evaluation partner to leading AI labs, backed by Accel, Prosus, and Nexus, with over 1 million contributors across 60+ countries generating high-quality, scalable training data through a decentralized network.

We are now hiring our first dedicated sales leader to own and grow relationships with the labs that matter most — physical AI, voice AI, and frontier model builders. This is a category-defining role at the intersection of human intelligence and AI training.

What You'll Own

• Own pipeline and relationships with physical AI and robotics labs — humanoid, autonomous systems, and embodied AI teams building the next generation of intelligent machines
• Drive partnerships with voice AI and speech model teams requiring specialized audio, multilingual, and conversational datasets
• Penetrate frontier AI labs and LLM builders who need RLHF, red-teaming, preference data, and human evaluation at scale
• Manage the full sales cycle: from identifying and qualifying research-side champions to closing with procurement and legal
• Build and execute the GTM playbook for human-in-the-loop verification-as-a-service across US and UK markets
• Own and close 6- to 7-figure contracts; define pricing, packaging, and commercial structure with the founding team
• Own client education, value delivery, and early-stage evangelism — you are the face of Humyn Labs to the labs that will define AI
• Act as the voice of the customer: feed insights back to product and delivery teams to shape our roadmap

What Makes You a Fit

Non-negotiable:

• 1–4 years of recent, hands-on experience selling datasets, annotation services, RLHF pipelines, or model evaluation to AI labs — this is the single most important filter for this role
• Direct relationships within physical AI or robotics labs (e.g., Figure, Physical Intelligence, Apptronik, Boston Dynamics, or similar) and/or voice AI labs (e.g., ElevenLabs, Hume, Cartesia, Deepgram, or similar)
• Familiarity with how frontier labs and applied AI teams procure training data — who the buyers are, how budgets flow, and what a typical deal structure looks like
• Prior experience at a data labeling, RLHF, or AI evaluation vendor — Scale AI, Appen, Surge, Toloka, Labelbox, Datasaur, or similar — strongly preferred

Strong to have:

• 5–10 years total in AI data services, model evaluation, or ML tool sales
• Proven track record closing 6-figure+ contracts (ideally $500K+) with technical buyers — AI labs, MLEs, data heads, research leads
• Experience navigating research-to-procurement sales motions where the technical champion is not the budget holder
• Deep Bay Area network across AI — lab founders, research VPs, ML leads, and procurement heads
• Strong consultative selling instincts: you ask before you pitch, and you build trust before you build pipeline
• Ability to operate as a GM for U.S. growth — setting strategy, hiring behind you, and owning outcomes end to end

Why Kgen/Humyn Labs

• Led by second-time founders with proven exits and a track record of taking companies public — you are joining a team that has done this before
• Backed by marquee institutional investors including Accel, Nexus, and Prosus
• 1M+ contributors already active across our global network — real scale, not a pitch deck
• Verified human network spanning 60+ countries with diverse functional skills and deep user personas
• Active partnerships with leading AI labs; you will have real products and real clients to build on from day one
• Zero politics. Full ownership. You define how this market gets built in the US.
