Backing AI founders from Day One
Day One Angels is an early-stage angel fund investing in pre-seed and seed AI startups — combining capital with hands-on founder support.
Pre-seed & seed • AI-first • Founder-led
An angel fund built for the earliest days
Day One Angels partners with ambitious founders at the pre-seed and seed stages. We invest early, stay engaged, and help teams navigate the hardest part of company-building: turning early traction into a fundable, scalable business.
We believe the best outcomes come from capital plus consistent support — not just a check.

Support first. Investment when it makes sense.
Founders in our subscription program receive hands-on support as they build. When a company reaches the right level of traction and alignment, we may invite them to formally apply for investment.
Joining the program does not guarantee funding — but it ensures you’re building with investor-level feedback from day one.
