Our story

A digital partner built on long-term relationships.

Sonic Infosystem began building websites in 2003 and was incorporated in Navi Mumbai on 8 August 2008. Over two decades we have designed, developed and marketed websites for manufacturers, exporters, pharmaceutical and medical device companies, retailers and service businesses across India and overseas.

Our work combines three disciplines that are usually split between separate vendors: design, engineering and search marketing. A single team plans the information architecture, designs the interface, writes and optimises the content, develops the platform and then grows its visibility on Google and in AI-driven search. The result is accountability from the first wireframe to the monthly performance report.

Many of our clients have worked with us for more than a decade. That continuity is the measure we care about most: websites that keep performing, and relationships that keep growing.
