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

Celtra builds creative automation software for marketers and agencies to produce and serve digital ads at scale. The tech stack spans Scala, Node.js, and Go backends with React/Vue frontends, backed by Snowflake, MongoDB, and AWS—a shape typical of companies managing high-volume ad production and delivery. Active hiring remains sparse (1 role in last 30 days), but projects reveal active development across frontend redesign, backend APIs, and data infrastructure improvements, while pain points point to challenges in customer acquisition, churn reduction, and enterprise-grade production workflows.

About Celtra

Celtra is a creative automation platform serving marketers, media platforms, and agencies. The product sits at the intersection of creative design tooling and ad-tech infrastructure, enabling teams to design, produce, and serve interactive and video ads (outstream, rich media, HTML5 display, interactive video) across digital channels. The company operates from hubs in New York, London, and Ljubljana, with a remote-first structure. Core customers include global brands in media, consumer goods, and advertising technology. The platform's differentiation rests on both creative enablement (design and production tooling) and performance delivery (trafficking and serving ads through major ad exchanges and programmatic platforms including Google, Meta, and The Trade Desk).
