Raising money for an AI startup is both exciting and overwhelming. The space is hot, investors are everywhere, but finding the right backer is still extremely challenging.

Here’s a quick gut-check before you start reaching out (a checklist by Andrew Ackerman from the How I Raised It podcast):

  • Make sure your startup is actually fundable, not just fund-seeking.
  • Don’t let one weak link in your story (team, traction, market, or plan) sink the whole pitch.
  • Show progress. Even small milestones make you more credible.
  • Be clear with your ask—how much, why, and what it gets you.
  • Skip the mass emails. Warm intros open doors, cold blasts close them.

This list of 25 AI-focused investors is designed to save you time and give you intel on the best VC firms to fund your business. You’ll find their websites, past investments, preferred stages, and key partners to reach out to (yes — with LinkedIn links). It’s your shortcut to spend less time guessing and more time building.

Let’s dive in.

Ending Note :)

Fundraising is tough, but remember—you don’t need every investor to say yes. You just need the right one to believe in you.

The investors on this list are already betting big on AI. They’re looking for founders who are bold enough to solve hard problems and clear enough in their vision to pull others along. That could be you.

So do the work. Refine your story. Share your progress. Reach out with confidence.

Because the future of AI won’t be built by chance—it’ll be built by founders who take the shot.

Good luck :)
