Celtra, a company offering tools for rich media ad creation, mobile ad serving, and analytics, just announced that it has raised $4 million in new funding.
The round was led by SoftBank Capital, and SoftBank’s Ron Fisher is joining the board. Existing investors GrandBanks Capital and Fairhaven Capital also participated in the new funding.
Celtra says it reached profitability in the third quarter of last year, and saw 300 percent revenue growth year-over-year. It also says its customers and partners include “four of the top five mobile ad networks” and “eight out of the top 10 media agencies.” If that’s a little vague for you, the press release also includes an endorsement from Razorfish Chairman Clark Kocich, who says Celtra is “experiencing rapid adoption by advertising agencies” because it’s “constantly innovating and pushing the industry forward.”
It’s a strategic investment, Celtra says, because it can use SoftBank’s connections to find more opportunities in Japan and elsewhere in Asia. The company also plans to use the money to bring product development operations to San Francisco.
Celtra previously raised a $5 million Series A. It launched version 3 of its AdCreator product back in June.
