Sigma

Founded in 1994 and family-owned ever since, Sigma has grown from a regional IT firm into a multi-practice talent solutions partner serving clients across the United States and internationally. Sigma partners with technology, life sciences, and enterprise organisations to deliver exactly the talent they need, from a single specialist to a fully managed workforce programme. The company operates as a thinking partner, helping clients get ahead of talent needs before requirements are written, then executing across every channel to deliver quality candidates without operational friction.

Sigma specialises in five core practice areas: IT and Engineering, where the company has been placing senior engineers since 1994 with passive candidate networks that reach passive candidates competitors cannot find; Life Sciences and Biotech, where Sigma has exclusively built networks since 2001 across pharma R&D, clinical trials, regulatory affairs, and biotech operations; Healthcare, where the company brings sector-specific rigour to clinical and non-clinical talent placement across the United States; Enterprise VMS and MSP programmes, where Sigma operates as a proven supplier within major enterprise programmes with full compliance and procurement fluency; and Global Talent, where the company provides access to vetted international talent networks including Europe-based senior engineers for organisations where data sensitivity or security requirements make traditional offshore markets impractical.

Sigma serves clients across the United States from its Massachusetts headquarters, with candidate networks and client relationships spanning the country and global reach for international talent programmes. The company is recognised as an Inc. 500 fastest-growing private company, a Deloitte Fast 50 technology sector growth honouree, and an NMSDC-certified minority business enterprise. Clients choose Sigma over competitors because the company builds deep expertise in the sectors it serves rather than attempting to cover every market, resulting in better candidates, faster delivery, and client relationships that outlast individual hires.
