Index Companies, LLC

Along 44th Street’s quiet mid-block stretch, Index Companies, LLC operates as a software company. The firm shares the same block with publishers and legal offices, tucked between Sixth and Broadway. No signage hints at its presence, just a numbered door on a limestone facade shared by an architectural studio.

At 28 W 44th St #16, New York, NY 10036, the company occupies a mid-century office converted from print to code decades ago. The building’s elevators still carry the scent of aged paper and polished brass, a backdrop that rarely changes. System integrations and API maintenance sit beside legacy migrations and compliance audits on the roster.

On any given quarter, teams handle ERP rollouts, data warehousing, and user-access reviews. Beyond infrastructure, they deliver dashboard design and security hardening for financial clients. Cloud migrations and identity management projects surface regularly, keeping the backlog fluid.

Reach the office by calling (917) 336-3059. A map to the building is available via the Google directions listing at https://www.google.com/maps/place?ftid=0x89c258ffe057bf11:0x26da1b51e0529017.
