Web apps & custom development in New York City, NY.

Need a custom web app for your New York City, New York business? GEO Marketing Group designs and builds booking systems, customer portals, dashboards, and calculators for New York City companies, working remotely from our Providence, RI studio. We build the custom functionality a template cannot handle, with clean code you own outright.

New York City's economy runs on finance, media, healthcare, and professional services, but the depth of its business base goes far beyond those anchors. JPMorgan Chase, Citigroup, and Goldman Sachs anchor a financial district that draws clients from every corner of the globe, while the New York-Presbyterian and Mount Sinai health systems employ tens of thousands across the five boroughs. Media and advertising giants cluster in Midtown; a dense tech sector fills office buildings from Flatiron to Hudson Yards. Below those headline industries sits an enormous ecosystem of law firms, accountants, contractors, architects, retailers, restaurateurs, and independent professionals - all competing for the attention of the same digitally connected customers.
