SRTA

Strata Critical Medical, Inc.

A healthcare services company that rushes donor organs to transplant centers via air and ground, under the Trinity brand, and provides surgical recovery, preservation, and cardiac perfusion staffing under Keystone. Born in 2014 as Blade Air Mobility, the helicopter passenger app, it pivoted during the pandemic to organ transport and rebranded as Strata in 2025. Fun fact: its old name "Blade" honored helicopter rotor blades.
