What We Look for at the Seed Stage

Exceptional Founding Team

Domain expertise, technical depth, complementary skills, and a demonstrated history of shipping under pressure.

Large Addressable Market

Global market opportunity of $1B or greater, with a credible narrative for how the company captures a defensible position within it.

Technical or Data Moat

A durable competitive advantage rooted in proprietary technology, unique data access, or regulatory barriers that increase over time.

Early Commercial Signals

Revenue, letters of intent, design partnerships, or pilot agreements that demonstrate genuine customer demand — not just hypothetical interest.

Global Ambition from Day One

Products and team structures designed to serve multiple geographies from the outset rather than treating international expansion as a later-stage event.

Seed Round Ready

A clear $5M deployment plan, 18-24 months of operational runway, and a credible hypothesis about growth stage milestones and the institutional investors who will lead it.
