What Jes Tech does

JES Tech is a privately held, SBA-certified Small Disadvantaged Business and Woman-Owned Small Business (WOSB/EDWOSB), headquartered in Houston, Texas, that delivers clinical, scientific, and engineering professional services to U.S. federal agencies. Founded in 2004 by Bobbie Jessie and Keith Sabin and led since April 2018 by Nellie Chappell-White (President and CEO), the firm operates four core service lines: Contract & Program Management (with DCAA-compliant financial reporting and FAR-compliant contract administration); Clinic Services & Management (operating the NASA Johnson Space Center Occupational Clinic, providing occupational medicine, flight medicine for astronauts, clinical laboratory services, pharmacy, and medical records); Biomedical & Physiologic Research & Science (laboratory services, environmental factors science, ground-based and flight analog bed rest study support, and biomedical operations training for ISS Crew Health Care System hardware); and Quality & Engineering Support (quality assurance for large spacecraft systems including high-bay water-immersion testing, configuration management, technical writing, and logistics support).

JES Tech earns revenue exclusively through federal procurement — operating both as a prime contractor and subcontractor — via negotiated contracts, IDIQ vehicles, and task orders under agencies including NASA Johnson Space Center, the U.S. Air Force 711th Human Performance Wing, U.S. Special Operations Command (POTFF), and the U.S. Department of Energy (Hanford Site). Pricing is set by federal procurement processes rather than public pricing, and customer segments are purely government (Vertical segmentation). Its go-to-market is enterprise field sales — direct pursuit of agency contracts and cultivation of long-tenured client relationships, augmented by participation in NASA Small Business Council events, Nevada APEX Accelerators outreach, and STEM engagement programs such as NASA MITTIC.

The company's competitive posture rests on its SDB/WOSB/EDWOSB certifications and KBR-JES Tech Mentor-Protégé Agreement — earning NASA Agency-wide Protégé of the Year in 2019 and 2020 — together with deep domain expertise in space-medicine research, occupational health at DOE sites, and quality assurance for NASA spacecraft programs (Orion, ISS, Commercial Crew). The firm has grown roughly threefold in headcount since founding and was selected for its first NASA JSC prime contract (REMIS 2) and its first DOE Hanford prime contract in January 2024.

Direct peers

• Inomedic Health Applications: Occupational and environmental health services provider to federal agencies. JES Tech teamed with Inomedic on the DOE Hanford Site Occupational Medicine Services Contract, making them a directly comparable small-business federal health services peer.
• Bastion Technologies: Small-business NASA and DoD contractor providing engineering, scientific, and technical support services out of Houston and other NASA center locations. Directly comparable as a similarly-sized WOSB/SDB-eligible contractor pursuing the same federal set-aside opportunities.
• Aegis Aerospace: Houston-based aerospace services firm providing engineering, research, and technology development to NASA and DoD. JES Tech's VP of Business Development Joel Krouse previously worked at Aegis, and the firms compete for similar microgravity, ISS, and human-performance research work.
• Wyle (now part of KBR): Prior to its KBR acquisition, Wyle Life Sciences provided scientific, engineering, and life-sciences support to NASA — a near-identical service profile to JES Tech's biomedical and physiologic research offering. Now operating as part of KBR's Science & Space business.
• Stinger Ghaffarian Technologies (SGT, now part of KBR): Acquired by KBR in 2018, SGT was a large NASA contractor providing mission operations, engineering, and astronaut-related support services. Historically competed with JES Tech on similar NASA JSC human-spaceflight support scopes.
• DB Consulting Group: Small disadvantaged business federal contractor supporting NASA, DoD, and other federal agencies with IT, engineering, and scientific services. Listed as a JES Tech partner and operates as a comparable small-business set-aside competitor on federal vehicles.

Broad incumbents

• KBR: Major federal services prime and JES Tech's NASA Mentor-Protégé partner. KBR provides the full scope of human-health-performance, life sciences, and mission support to NASA, with KBR as both a subcontractor customer for JES Tech and a broader competitor on related recompetes.
• SAIC: Large federal IT and engineering services prime that leads the SMAEC II contract on which JES Tech is a subcontractor. SAIC pursues similar NASA and DoD scientific/engineering support work as a broader-portfolio incumbent competitor.
• Leidos: Major federal scientific, engineering, and health services contractor supporting NASA, DoD, and DOE. Competes with JES Tech across several biomedical, life-sciences, and mission-support recompetes as a larger incumbent with deeper bench scale.
• Booz Allen Hamilton: Large federal management and technology consulting prime supporting NASA, DoD, and other federal agencies. Pursues adjacent human-performance, life-sciences, and aerospace engineering work as part of its broader federal services portfolio.
