Fundraising prep is broken. AI can write your deck, your YC application, your email to investors. All polished. But the hardest part of fundraising is still telling the story out loud. Rehearsal Room gives founders a private space to practice before the real meeting. Five AI investor types with different styles and intensity. Ten minutes per session. Real feedback on how your story lands. Free to try. No deck needed. Just show up and tell your story. No storing of data, unless you consent.
