Founding Marketing Lead

About Mithrl

We envision a world where novel drugs and therapies reach patients in months, not years, accelerating breakthroughs that save lives.

Mithrl is building the world’s first commercially available AI Co-Scientist—a discovery engine that empowers life science teams to go from messy biological data to novel insights in minutes. Scientists ask questions in natural language, and Mithrl answers with real analysis, novel targets, and patent-ready reports. No coding. No waiting. No bioinformatics bottlenecks.

We’re the fastest growing tech-bio startup in the Bay Area, with 12X YoY revenue growth and customers across three continents—from small biotechs to top-5 pharma. Our product is working, our customers are winning, and the story is just beginning.

Why This Role Matters

We’ve built something scientists love. Now we need the world to know.

As the Founding Marketing Lead , you’ll turn product strengths into market momentum. You’ll translate what makes Mithrl magical into content that resonates with scientists, sparks inbound interest, and builds credibility with the industry. This isn’t about fluff. It’s about owning and crafting narratives that drive growth.

You’ll work closely with the founders, product, and GTM teams to scale storytelling, boost visibility, and support everything from customer success to deal flow.

This is a high-ownership role with room to shape the brand, grow a team, and accelerate into a VP or CMO track as the company scales.

What You’ll Do

• Build and own Mithrl’s voice across LinkedIn, website, and thought leadership
• Turn product features into sharp, compelling content that drives awareness and understanding
• Create case studies, demo videos, memes, and short posts that make technical breakthroughs understandable (and shareable)
• Collaborate with sales and customer teams to amplify success stories and build trust with prospects
• Run light paid, SEO, or newsletter experiments to test new growth channels
• Work with design to produce clean, clear, and fast marketing assets
• Lay the foundation for a world-class marketing function, from messaging to content ops
