Horizon3.ai is a fast-growing cybersecurity company on a mission to help organizations proactively find, fix, and verify exploitable attack vectors before criminals exploit them. The flagship product, NodeZero, delivers production-safe autonomous pentests and security assessments that scale across internal, external, cloud, and hybrid environments. The company was founded by a fusion of former U.S. Special Operations cyber operators, startup engineers, and cybersecurity practitioners. You will be the second Commercial Account Executive responsible for growing the Commercial business segment across the French region. This is a market-building role where you'll develop new customer relationships, create new logo momentum, and work closely with partners and cross-functional teams to expand Horizon3's presence in France. Key responsibilities include: growing the Commercial business through strong customer engagement and partner collaboration; creating new logo pipeline that fits the local market; building and managing opportunities with clear ownership and follow-through; collaborating with partners, distributors, MSSPs, Enterprise sellers, and Sales Engineers; contributing to partner and territory plans; working across Marketing, Channel, Sales Engineering, and Sales Ops; gathering and sharing market feedback; and representing Horizon3 professionally with customers and partners. Success means creating new logo momentum, building strong relationships with customers and internal teams, managing opportunities consistently, becoming productive quickly, and bringing useful market insights back into the business. The Commercial team collaborates at the Amsterdam hub while working in local markets. Travel within the French region is part of the role. You'll work in a scaling business where structure is still being built, with a proactive, builder mindset focused on increasing reach, efficiency, and impact.
