San Francisco’s Velti has reached an agreement to purchase Atlanta’s Air2Web for $19 million.
Velti is the creator of Velti mGage, an online mobile marketing and advertising platform. Air2Web is a venture-backed firm providing SMS solutions for mobile marketing and corporate communications. Velti says it is buying Air2Web for its technology and access to its “marquee customers.” Those clients include American Express, Citigroup, HSBC, Barclays Bank, AT&T, and Comcast.

Velti says Air2Web is a leader in real-time customer relationship management because its technology allows marketers to communicate with customers at the point of purchase. Air2Web also offers mobile customers service applications and mobile website development.
