Delta Development Team Solidifies Leadership and Continued Support in Prehospital Blood Space with Successful Series A3 Close

TUCSON, Ariz., Aug. 4, 2025 /PRNewswire/ -- In a U.S. market where fewer than 2% of EMS agencies have implemented prehospital blood programs—and over 70% of those rely on Delta Development Team (DDT) systems—DDT is emerging as the clear leader in a rapidly expanding space. Today, the company announced the successful close of its Series A3 funding round, marking a major milestone in its growth trajectory.

Unlike many startups navigating a tight funding landscape, DDT completed its extended Series A round in just nine months. This momentum is a direct result of its increasing adoption across both civilian and military healthcare sectors, its growing reputation as the gold standard in cold chain technology, and its alignment with evolving protocols that prioritize earlier access to blood in the field.

"This market is transforming fast—and we're not just keeping pace; we're driving the shift," said Montgomery Leija, CEO of Delta Development Team. "From military partnerships to frontline EMS units, our systems are becoming foundational infrastructure for evolving prehospital blood programs."

The Series A3 round was backed by a mix of strategic capital and non-dilutive funding, including support from the U.S. Air Force's TACFI (SBIR) program. This funding structure enables DDT to scale quickly while minimizing dilution and operational risk.
