In TISTA Science and Technology Corporation, B-422891.2, et al. (Jan. 23, 2025), TISTA protested a National Institutes of Health (NIH) awarding of a task order for software development services to Tantus Technologies, alleging improper evaluation of both offerors’ technical proposals. The core issue was GAO’s finding that NIH treated TISTA and Tantus unequally, particularly with respect to their surge staffing approaches, despite nearly identical solutions.
