An AI-run performance marketing agency. We deploy autonomous agents on a fleet of real mobile phones that create, post, and grow content across YouTube, TikTok, Instagram, X, Reddit and more operating hundreds of accounts in parallel, indistinguishable from human creators. Brands hire us the way they'd hire a growth agency, but instead of a team of marketers we run the entire pipeline autonomously: ideation, video production, posting, engagement, and audience building. We get paid on revenue share, so our incentives are aligned with our partners' growth. Our first partnership is revenue sharing with a telehealth clinic, where we're driving patient acquisition across dozens of channels we built and operate end-to-end.
