Founding Enterprise Account Executive

HireSweet is hiring a Founding Enterprise AE for one of its clients: a pioneering Speaker Intelligence AI redefining how machines understand spoken language.

Their speaker diarization technology distinguishes speakers with unmatched precision, regardless of the spoken language, making AI understand not just what is said, but who said it and when.

Founded by voice AI experts with 10+ years in the industry (ex-CNRS research scientists), they've built the 9th most downloaded open-source model on HuggingFace with 52 million monthly downloads and over 200,000 users worldwide. After raising €8M from leading international VCs (Crane Venture Partners, Serena, and angels from HuggingFace and OpenAI), they are now scaling their enterprise platform.

From meeting transcription and call center analytics to video dubbing and voice agents, they powers the next generation of voice-enabled applications across industries that depend on understanding who speaks and when.

As the 2nd Account Executive, you'll be the driving force behind the commercial growth. This isn't just any role - you're a founding member of their go-to-market motion, and you will learn first‑hand how to scale a go-to-market engine in one of the most exciting deep‑tech startups in Europe.

You’ll focus on two core streams:

Demand Generation

• Tap into and value a unique growth engine: a community of 170,000+ open‑source users, thousands of new users every month, and dozens of inbound leads from the website, HF and GitHub.
• Help identify and qualify high‑potential prospects, craft messaging by vertical and geography, and build repeatable campaigns that turn developer interest into qualified opportunities. You’ll also help set the foundations for future sales hires, and teach them how it’s done.
• Shape and evolve our sales playbook by partnering with our RevOps to continuously improve our CRM and sales processes as our enterprise pipeline grows - using insights from the field to optimize our motion.

Driving our GTM function

• Support the sales pipeline from first touch to signed deal. As you ramp up, you’ll take full ownership of your own deals — from sourcing to closing — and support our early commercial customers.
• Drive expansion within existing accounts - Monitor product usage patterns, identify upsell signals, and execute account‑specific growth strategies to maximize customer lifetime value.
• Develop deep voice AI expertise - Become fluent in the conversational AI landscape—competitive solutions, emerging trends, customer use cases—positioning yourself as a trusted advisor in the space.

What makes this role unique:

You’ll work directly with CEO in a developer‑first, product‑led environment. You’ll have direct client exposure from day one and play a pivotal role in defining how we sell one of the most innovative voice AI platforms in the market. A successful candidate can also expect to accelerate their commercial career in a fast‑paced rapidly scaling environment.

What they're looking for

Must‑haves:

• Proven B2B sales experience, ideally in SaaS or deep‑tech - You've demonstrated your ability to sell in a technical, complex environment and have a track record of closing deals.
• Exceptional communicator - Strong written and verbal skills with the ability to translate technical concepts into clear business value for diverse audiences.
• Highly organized with exceptional follow‑up and multitasking skills - You manage multiple enterprise opportunities simultaneously with discipline, keep deals moving forward, and never let anything slip through the cracks.
• Self‑starter who thrives in ambiguity - You're energized by building from zero, comfortable without a rigid playbook, and able to operate autonomously in a fast‑moving startup environment.
• Ambitious and entrepreneurial mindset - You want to rise faster than a traditional career path allows, you're happy to roll up your sleeves and do whatever it takes, and you're excited to build a business from the inside.
• Eager to learn fast - Particularly about AI, voice technology, and developer tools—you're intellectually curious and adapt quickly to new domains.
• Fluent in French and English - Comfortable operating in both languages professionally.

Nice‑to‑haves:

• Experience with sales tools - Familiarity with HubSpot, Notion, LinkedIn Sales Navigator, or similar platforms.
• Experience in AI/ML, developer tools, or API‑driven products - Familiarity with the voice AI landscape or adjacent spaces will accelerate your ramp.
• Product‑led growth (PLG) sales experience - You understand how to convert engaged users into paying
