Even in his final months, Cyrus Jirongo relentlessly pursued significant business opportunities across Africa, remembered by friends for his unconventional deal-making and expansive vision. His death on December 13, 2025, in a road accident marked the end of a career spanning politics and ambitious real estate ventures.

• Philip Kisia, former Nairobi County Clerk, recounted Jirongo's direct approach in securing a meeting with President Félix Tshisekedi of the Democratic Republic of Congo (DRC) for a corporate credit business venture in October 2023.
• David Murathe, former Jubilee vice chairperson, described Jirongo as a "big thinker" capable of crafting "multi-billion-shilling ideas" ranging from Libya's post-conflict reconstruction to real estate in Ruai.
• Fred Amayo, a longtime friend, clarified that Jirongo's wealth predated his political career, asserting he had already built properties like Hazina Estate and Kemri Estate by his late 20s.
