Founding Team Co-Builder: Shape startups from Day One

About Hexa

Hexa started as eFounders in 2011 and has since become a leading startup studio. We’ve built over 40 companies, including Aircall, Spendesk, Front, Swan, and Yousign, with a combined valuation of $4.5bn. We specialize in software, with a strong track record in AI, Future of Work, fintech, climate, defense and cybersecurity.

Join the Core Team

The team that co-builds every startup we launch. You work across multiple ventures in parallel, embedded with founders from day one, across product, design, go-to-market, recruiting, finance, and legal. If you want to be at the heart of company creation, this is it.

Join a Hexa venture early

Every year, Hexa co-founds around 12 new startups. Joining one in its first months means taking a founding employee role: you build the product, shape the culture, and own a real stake in the outcome, with the full support of Hexa’s Core Team behind you.

Join a Hexa portfolio company

Some of our startups are further along. They’re scaling, hiring, and looking for strong profiles to help them grow. If you want the energy of a startup with more structure and traction already in place, this is the path.

What we’re looking for, across all three

• Strong expertise in your field, ready to create impact from day one
• Entrepreneurial mindset: you thrive in uncertainty and love building from scratch
• Ownership and autonomy: you drive execution without waiting for direction
• Hands-on attitude: no task is too small or too big
• Previous experience in a fast-growing or early-stage company

Why join

• Entrepreneurial minds: Work alongside seasoned entrepreneurs and founders who are experts in their fields.
• High-impact role: You won’t just execute. You’ll shape companies from day one and influence key decisions.
• Unlimited learning: Immerse yourself across multiple startups and industries. You’ll grow fast.
• Unique network: Access to top-tier founders, investors, and industry experts, plus exclusive events.
• A caring environment: A team that values collaboration and is committed to positive impact, inside and outside our startups.
