How do founders create AI UGC and avatar video ads without a creator budget?

Tools like Arcads and HeyGen turn a script into a realistic person talking to camera for roughly $10 to $30 a video, versus hundreds per human creator, and the batch engines can render one script across dozens of AI actors for hook testing. The catch is that audiences increasingly punish obviously fake avatars, so the winning use is volume testing and voiceovers, then reinvesting in real creators once you know which angle converts. Treat AI UGC as a testing lab, not the final brand voice.
