About Celtra

At Celtra, we are building two world-class products. The first product (Creative Enablement or CE) has already been a growing market leader for a couple of years now, helping companies such as CNN, TripAdvisor, Bloomberg, NBCU, and Business Insider monetize their advertising inventory. It covers the entire lifecycle of launching a campaign: ad product ideation and design, ad content production, trafficking tags, and tracking performance. With our second, younger product (Creative Automation or CA), we are chasing a much bigger opportunity by helping brands produce a massive amount of content better, faster, and more efficiently. Although its development is still in the early days, it already includes an impressive list of customers such as Spotify, adidas, Shopify, Unilever, P&G, LEGO, Lululemon, and many others.
