About Poseidon

Poseidon is building the data infrastructure the next generation of AI will depend on.

Foundation models today aren’t limited by compute or model design — they’re bottlenecked by data. The kind of rare, high-quality, and IP-safe data that actually improves performance. Not the 99%, but the rare 1% — long-tail, edge-case, multi-modal data that can’t be scraped or synthetically generated.

Poseidon is a decentralized data layer that connects AI companies with the specific datasets they need. We’re not just building another marketplace — we’re building the infrastructure that makes scalable, compliant, and demand-driven data sourcing possible. Backed by a16z, we’re early, moving fast, and looking for sharp, mission-driven teammates to help shape this category.

The Role

We are looking for a part-time MBA Fellow to join our team. This role is ideal for MBA students or recent graduates interested in working at the intersection of AI and Web3, with a focus on business development, strategy, and market intelligence in rapidly evolving technology sectors.

What You’ll Do:

• Gain hands-on experience at a top a16z-funded company with active engagements across Fortune 500 enterprises and leading AI startups.
• Develop a deep understanding of emerging markets in AI, data infrastructure, and Web3.
• Work directly with the executive team on high-impact projects, from new market entry to partnership strategy.
• Receive mentorship from Poseidon’s leadership, including executives with backgrounds in top technology companies and venture-backed startups.
• Build a strong network of investors, corporate partners, and AI/web3 leaders.

Fellowship Focus Areas (open-ended):

• Competitive & Market Analysis: Research trends in AI training data, synthetic data, Web3, and compute infrastructure; develop strategic insights to inform product direction.
• Business Development & Partnerships: Identify and evaluate potential supply- and demand-side partners across industries such as enterprise SaaS, media, healthcare, and crypto.
• Special Projects: Work cross-functionally on priority initiatives, such as fundraising support, product-market fit validation, and thought leadership content.

What We’re Looking For:

• Current MBA student or recent graduate with a strong interest in emerging technologies (AI, data infrastructure, Web3).
• Prior experience in consulting, investment banking, venture capital, or strategy & operations at a high-growth company.
• Strong analytical and research skills; comfortable synthesizing complex information into actionable insights.
• Excellent communication and presentation skills.
• Self-starter mindset; excited to work in a fast-paced, early-stage startup environment.
