Backed by a16z Speedrun, we build AI agents that help consumer subscription brands — like Higgsfield and Promova — retain more users, extend lifetime value, and grow fast. We're an incredibly driven team working on a problem that affects every consumer on the planet. If that sounds like your kind of thing, we'd love to meet you.

Our co-founders are Azamat Khamidov and Benazir Toleubekova. Azamat built a Telegram AI product from zero to five million users in four months, the first acquisition inside Telegram. Benazir received a full scholarship to Beijing University of Technology at 15. Joined Taobao at 17. At Alibaba, architected the core recommendation engine serving 500M daily users.
