About
Leidos Holdings, Inc. is a Reston, Virginia-based defense, intelligence, and civil government IT services company — publicly traded on the New York Stock Exchange (NYSE: LDOS) as an S&P 500 Industrials component — providing national security solutions (IT services for US intelligence community, Department of Defense analytics, cybersecurity), health and civil government services (VA electronic health records, HHS IT systems, FAA air traffic control modernization), and commercial services through approximately 47,000 employees. In fiscal year 2024, Leidos reported revenues of $16.7 billion (+8% year-over-year), with the National Security & Digital segment generating the majority of revenue from classified intelligence community IT programs and Department of Defense cybersecurity and analytics contracts, while Health & Civil generated revenue from the Leidos Digital Modernization contract for the Department of Veterans Affairs electronic health records (replacing VistA legacy EHR with Oracle Cerner's Millennium platform) — a 10-year, $10+ billion program that was simultaneously Leidos's largest contract and largest program execution challenge. CEO Tom Bell (joined 2023, previously from Rolls-Royce North America) has focused Leidos on transitioning from IT services to technology-enabled solutions: augmenting traditional government IT labor with proprietary software products (Leidos AI/ML platforms, cloud migration tools, cybersecurity automation) that generate higher margins than staff augmentation. The $1.65 billion acquisition of the security detection and automation business of Smiths Group (X-ray security screening equipment — baggage scanners for TSA checkpoints) in 2021 expanded Leidos into physical security hardware and detection systems for government and commercial airports.

About
Paycom Software, Inc. is an Oklahoma City, Oklahoma-based human capital management (HCM) software company — publicly traded on the New York Stock Exchange (NYSE: PAYC) as an S&P 500 component — providing a single-database HCM platform that manages payroll, talent acquisition, talent management, HR management, and time and labor for over 37,000 clients and 7 million+ employees through recurring subscription revenue of $1.88 billion in fiscal year 2024 with a 41% EBITDA margin and 90% annual client retention rate. Founded in 1998 by CEO Chad Richison (who funded the startup by selling his house and cashing out his 401k at age 27), Paycom was among the first companies to process payroll entirely online — pioneering cloud-based HR technology before SaaS was an established software delivery model. Paycom's single-database architecture (all HCM modules sharing one data layer, eliminating the file imports and reconciliation required by multi-vendor HR stacks) enables Beti®, the employee self-service payroll product where employees review and approve their own paychecks before processing — reducing payroll errors at the source rather than correcting them after the fact. In 2025, Paycom launched IWant™, a command-driven AI engine allowing users to access employee information through voice-to-text or typed natural language commands — named a Top HR Product of 2025 by HR Executive magazine.
