Creative automation platform for digital advertising production and delivery

Software Development New York, NY 201–500 employees Founded 2006 Privately Held

Celtra builds creative automation software for marketers, agencies, and ad platforms to design, produce, and serve digital ads at scale. The stack spans AWS, Snowflake, and Spark for data processing, alongside frontend frameworks (React, Vue) and video/HTML5 rendering—a shape that reflects dual needs: real-time ad serving and batch creative pipeline work. Active hiring across engineering, sales, and data (with internship intake) and a project list heavy on backend APIs, data infrastructure, and AI-powered creative features signal a company scaling toward enterprise production volumes while addressing internal data orchestration costs.
