Backing AI founders from Day One
Day One Angels is an early-stage angel fund investing in pre-seed and seed AI startups — partnering with technical, product-driven teams building enduring companies.
Pre-seed & seed • AI-first • Founder-led
An angel fund built for the earliest days
We partner with ambitious founders at the pre-seed and seed stages. We invest early, move quickly when there’s conviction, and aim to be a helpful long-term partner — not just a check.
Our focus is simple: back strong teams building AI-first products with a clear wedge and a path to meaningful adoption.
