In 2015, Iran signed a landmark deal with global superpowers. An end to Iran's isolation pointed to a bright future for the country's budding tech scene -- but then, Donald Trump, a vocal critic of the nuclear agreement, won the U.S. presidency and once-eager foreign investors got spooked. This week on Decrypted, Bloomberg's Ladane Nasseri visits the founders of a homegrown e-commerce startup called Koodakoo as well as several other companies. These young entrepreneurs are awaiting Trump's next move -- and what his actions would mean for the future of their businesses -- as he threatens to renegotiate and even withdraw from the nuclear agreement.
