Why this role exists, right now

thymia turns 15 seconds of speech into 30+ clinical and wellbeing signals in real time, with clinical-grade accuracy. We are the health and safety intelligence layer for all voice AI — already trusted by leading automotive manufacturers, major telehealth providers, and some of the world’s largest AI platforms. We hold the first regulated voice biomarker models globally.

We just closed a round that brings our total funding over $20M. Inbound is outpacing what the CEO can personally run, deals are stacking up across the US, UK and Japan, and we need an owner for the US commercial motion before pipeline becomes the bottleneck on the company. We have a clear pathway to $100M+ ARR within 2 years, in large part based on concrete framework agreements already secured, but awaiting commercial implementation.

It’s your responsibility to help us realise it.

This is not a role where you take a playbook and execute a classic SaaS sales motion. It is a technical knowledge-intensive role where you take a warm, named pipeline across multiple industries and double it, thinking on your feet, moving at speed, juggling multiple priorities without dropping the ball. You will be setting the base for a growing GTM team across multiple sites globally and be part of a high-velocity team where impact matters more than job titles, and no task is above or beneath any of us.

What you’ll own

• Close the deals in front of us. Run live enterprise opportunities end-to-end — discovery, technical scoping with our science team, pricing, procurement, security review, and signature. We expect first closed deals inside 90 days from existing and new pipeline.
• Build the outbound motion. Identify and prioritize the next 50 accounts across voice AI platforms, automotive OEMs and Tier-1s, and telco / CCaaS, finding opportunities wherethymia can drive safety, wellbeing, engagement or cost efficiency — and helping us hit our revenue goals. Run targeted outbound personally until volume justifies an SDR hire.
• Prepare sales materials & meetings: Prepare sharp, high-quality decks, briefs and follow-ups for client, partner and investor meetings.
• Know the landscape and act on it: Develop and maintain a deep understanding of the voice AI landscape — customer use cases, competitive solutions and emerging trends — and feed that back to HQ on a weekly cadence — enough to actually move the roadmap.
• Own the CRM and the forecast: Every meeting logged, every deal staged, every next step dated. Our global team plans against this data — it is not admin, it is product.
• Lead commercial contracting: Drive MSAs, pilot agreements, and DPAs to close in partnership with our legal lead, with clean handoffs to our science and engineering teams for implementation.
• Coordinate across borders: Be a reliable link between our UK HQ and customers across the US, UK, Japan, Middle East and beyond — clear, timely and dependable across time zones.
• Be our voice in the US: Represent thymia at commercial and technical conferences for lead prospecting, use and develop your network across Voice AI to ensure we are top-of-mind whenever anyone mentions voice.

The growth path

This role has an explicit path to Head of US Business Development within 2 years. If you hit your number and build the foundation we expect in year one, you hire and lead the next commercial hires under you and become a member of the senior leadership team. If you would rather stay an elite individual contributor and keep carrying a number, that is also a great outcome — we will support either.
