Core Group Resources: From manual bottlenecks to a scalable staffing platform — built in six months
Core Group Resources partnered with Whale Song to turn years of operational friction into a strategic advantage.
The result was WorkCore — a purpose-built staffing operations platform that digitized CGR's recruiting, fulfillment, and onboarding workflows end to end, and positioned the company for a potential new line of business as a SaaS product for the broader maritime staffing industry.
About Core Group Resources
Core Group Resources (CGR) is a manpower and consulting firm founded in 2012 and headquartered in Katy, Texas, specializing in matching high-caliber talent to roles across heavy industries including maritime, offshore oil and gas, construction, renewable energy, aerospace, and logistics. CGR delivers executive search, direct and contract staffing, consulting, and personality assessment services through both domestic operations and an expanding international footprint in Trinidad & Tobago and Guyana.
The challenge
CGR's rapid growth created a painful gap between business ambition and operational capability. As placement volume increased, the cracks in their manual processes became impossible to ignore — and impossible to outrun.
Candidate matching required recruiters to cross-reference spreadsheets, email chains, and Bullhorn records by hand — a slow, error-prone process that introduced inconsistency and capped the volume any team could handle.
Compliance checks on licenses, certifications, and training turnaround times were tracked in Excel and Smartsheets, requiring constant manual oversight.
Onboarding coordination was fragmented across email, spreadsheets, and third-party tools with no single source of truth. And clients had no visibility into where their jobs stood in the fulfillment pipeline.
Each bottleneck compounded the others — slowing fulfillment timelines, increasing administrative cost, and preventing CGR's team from doing the high-value work that would actually move the business forward: client relationships, business development, and strategic growth.
Our approach
-
WorkCore integrates directly with Bullhorn via API to retrieve real-time candidate data — licenses, certifications, experience, and availability — and automatically matches candidates to open job requirements based on configurable criteria including training turnaround times and certification validity. What had previously taken recruiters hours of manual cross-referencing was reduced to an automated process returning results in minutes.
-
WorkCore replaced the fragmented combination of email, spreadsheets, and disconnected tools with a single platform managing the entire job lifecycle — from client job request through candidate selection, approval, and status tracking. Clients gained a transparent, real-time view into their placements, reducing inbound status inquiries and improving the overall client experience.
-
Compliance requirements — certifications, training timelines, documentation — were built directly into the platform's workflow, with automated notifications and status tracking replacing the manual oversight that had previously consumed significant logistics team capacity.
-
The MVP was delivered within six months of engagement start, with a phased roadmap for subsequent enhancements including a candidate portal, enhanced dashboard views, a configurable time-tracking and payroll module, and a full onboarding module to replace Smartsheets entirely.
