Head of Business Development

About the Company

Poseidon is building the data network for AI. Backed by a16z, we source, refine, and license high-quality, rights-cleared training data so that the people and institutions who create valuable data share in the value it produces. We believe the next decade of AI will be bottlenecked by access to proprietary, high-signal data, and we are building the rails to unlock it.

Responsibilities

• Take data partnerships from first conversation to signed agreement and live execution, owning structuring, negotiation, and close.
• Deepen and convert relationships across Korea's top consumer and technology platforms and major conglomerates.
• Translate Poseidon's product and technical vision into deal terms, working with product and engineering to shape market offerings.
• Drive Poseidon's local presence by partnering on PR, positioning, and narrative for local press, partners, and investors.
• Quarterback execution across functions and time zones, aligning legal, product, engineering, and global leadership.

Requirements

• 10+ years of experience in business development, partnerships, corporate development, or a comparable deal-driven role.
• Proven track record of personally negotiating, closing, and executing meaningful partnerships or transactions.
• Fully bilingual in Korean and English, with the ability to operate natively in both business cultures.
• Startup experience and a bias for "zero to one" environments.
• Strong command of business development, product, and communications.
• The presence and credibility to engage with C-suite executives at both startups and large conglomerates.

Preferred Qualifications

• Management consulting background or comparable training in structured problem solving.
• An existing network across the Korean startup, enterprise, or investor landscape.
• Experience in data, IP, healthcare, or frontier technology markets.
• A genuine interest in AI and a strong point of view on the trajectory of the technology.
