Aegis Mobile, a Columbia-based provider of mobile website services, said Tuesday it acquired a small Baltimore mobile marketing company for an undisclosed amount.

Part of Aegis' business is helping companies display their websites on a broad range of mobile devices. The company it acquired, Vesta Mobile, provides marketing services, such as text-messaging campaigns, for companies wanting to advertise on mobile devices.

Vesta was a startup company in the city's Emerging Technology Center, an incubator for technology companies. As part of the deal, the president of Vesta, Marcellus Alexander III, joined Aegis as marketing manager.
