Our Story
Founded in 2004 by Rom Agustin as a Los Angeles, CA startup, Callbox rapidly grew its customer base into new industry verticals and geographic areas, thanks to strong demand for its suite of innovative B2B marketing solutions.
Callbox established its Singapore office in February 2009, after two years of doing campaigns for local companies and multi-national organizations that want to expand in the Singapore and Southeast Asian markets. Today, Callbox Singapore is the company's regional hub of Southeast Asian Sales and Marketing Solutions.
