Temu appears unstoppable. Since the Chinese shopping app launched in the U.S. a year ago, it has become the number one e-commerce app in the country, with downloads skyrocketing 50x from 600,000 to 30 million in just one quarter, according to Bernstein analysts.

This week on Tech Check, we dive how Temu has hit Amazon’s weak spots to take the country by storm.
