AI-driven lifecycle marketing workflow built on top of customer engagement tools

Software Development San Francisco, California 2–10 employees Founded 2024 Privately Held

JustAI is a 2024-founded San Francisco startup building an AI layer for lifecycle marketing that plugs into Braze, Iterable, Customer.io, Segment and Snowflake. Its stack spans experimentation tools (Optimizely, Statsig, Eppo) and a polyglot backend (Python, Scala, Rust, Spark on Kubernetes), pointing to data-heavy content optimization. Hiring is engineering-led, but open work on a sales playbook shows go-to-market is still being formalized.
