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. NodeZero is used by ITOps/SecOps teams, consulting pentesters, MSSPs, and MSPs across organizations ranging from educational institutions to government agencies and Global 100 enterprises.
The company was founded by a fusion of former U.S. Special Operations cyber operators, startup engineers, and cybersecurity practitioners, committed to solving common security challenges: ineffective tools, alert fatigue, blind spots, checkbox security culture, skills shortages, and expensive consulting lead times.
You will be the second Commercial Account Executive focused on growing the Commercial segment (companies with fewer than 1,500 employees) across the Benelux region, specifically Belgium. You'll build strong customer relationships, create new logo momentum, and work closely with partners and cross-functional teams to expand Horizon3's market presence.
Key responsibilities include: growing the Commercial business through customer engagement and partner collaboration; creating new logo pipeline tailored to local markets; 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, Sales Ops, and Deal Desk; gathering and sharing market feedback; and representing Horizon3 professionally.
The Commercial team collaborates from the Amsterdam hub while staying close to local customers and markets. In-region travel is expected. Success means driving new logo momentum, building strong relationships, managing opportunities consistently, becoming productive quickly, and bringing valuable market insights back to the business.
Required qualifications: 4+ years of closing experience in IT or cybersecurity sales; Commercial or mid-market sales experience, ideally across multiple markets or regionally complex environments; confidence working with partners, distributors, and cross-functional teams; strong commercial judgment; ownership and accountability; curiosity and coachability; comfort in a scaling business with evolving structure; native-level Flemish fluency (French a bonus) plus strong English; and a proactive, builder mindset focused on market development and efficiency.
