AI companion platform for meaningful conversation at massive scale

Software Development San Francisco, California 51–200 employees Founded 2015 Privately Held

Replika operates a consumer AI companion platform with 35M+ users globally, built on Python + Docker + Kubernetes infrastructure. The company is product-driven (design and marketing dominate hiring, with only 1 active engineering role) and acutely focused on conversion funnels, UX motion systems, and scaling emotional AI experiences — suggesting the technical bottleneck is operational efficiency and user retention rather than core AI capability.
