Facebook ads API (application programming interface) partner AdStage announced that it has closed $1 million in funding. The startup will also launch an app partnership program that will give developers more app integrating capacity, according to Inside Facebook.

The new capital was provided by existing investor Digital Garage. This round brings AdStage's total raised funding to over $2.5 million since its 2013 launching. The startup will use the new funding to expand its 11-man team and reach more than 20 employees, the report detailed.

Chief Executife Officer and co-founder Sahil Jain said in a press release: "We've come a long way since we launched our first product, AdStage Express, on this stage last year. The LAUNCH audience was incredibly receptive to our vision so it's fitting to return and show extraordinary growth. In the time since, we've become a complete campaign management and analytics platform for businesses advertising across Google, Bing, Facebook & LinkedIn and we now offer a full suite of complementary apps under one roof which save advertiser's time and dramatically improve their performance."

Complementary marketing app developers can use the New AdStage Platform API for direct integration of their products into AdStage. The app partnership program will also help them monetize their products, Inside Facebook reported.
