Yello is a Chicago-based talent acquisition software company, founded in 2008 (originally Recsolu), whose enterprise platform runs campus and early-career recruiting for roughly 100 Fortune 500 employers across 70+ countries and 15+ languages. The product line covers campus planning, recruitment events, candidate sourcing, interview scheduling, a recruitment CRM, recruitment analytics and an AI campus recruiting agent, plus Yello Government Recruiting Solutions (YGRS) for public-sector hiring and the WayUp candidate marketplace and Symba new-hire readiness products acquired by the company. Yello Enterprise is delivered as per-customer tenant sites on yello.co and recsolu.com in US (us-east-1) and EU (eu-west-1) environments. Its integration surface with ATS and HRIS systems (Workday, Taleo, Oracle Recruiting Cloud, iCIMS, SAP SuccessFactors, Greenhouse, ADP) is real but is sold and provisioned through a partner/sales conversation rather than a public developer portal. The one openly reachable machine surface found is a remote Model Context Protocol server on the WayUp property, published with RFC 8414 / RFC 9728 OAuth discovery.
