Online advertising has been growing rapidly as dollars shift from traditional ad channels to digital ones.  According to eMarketer, by 2015 advertisers will spend $132.1 billion annually for online advertising.  Advertisers are increasing their investment in online advertising across multiple channels to drive greater lead generation, customer acquisition, and revenue.

One sign of that is how well companies in the digital ad industry are doing, both in terms of revenue and in fund raising.

For instance, this activity is fueling the expanding adoption of San Francisco-based Marin Software’s ad management and optimization platform.

In the wake of Marin’s success, Asia investment company Temasek led a $30 million round of funding along with SAP Ventures.

Joining the new investors in this oversubscribed round were existing Marin venture investors Benchmark Capital, Crosslink Capital, DAG Ventures, and Triangle Peak Partners.

The company sells online advertising management solutions, offering an integrated platform for managing search, social, display, and mobile marketing. The company provides solutions for advertisers and agencies. Marin’s technology powers marketing campaigns for over 1,500 customers managing more than $3.5 billion of annualized ad spend in more than 160 countries.

During the last year, Marin nearly doubled its customer base to 1,500 as well as the amount of annual spend managed on its platform to $3.5 billion.

Following Marin Software’s year of rapid international expansion, customer growth, and product innovation, and the closing of the recent financing, Frank van Veenendaal, President of Worldwide Sales and Services at salesforce.com, has joined Marin Software’s Board.

Longstanding Marin customers include iProspect, Neo@Ogilvy, Razorfish, Macy’s, Experian, and University of Phoenix.
