Early Days of Coinbase: A 5-Person Team Once Faced Nearly 20,000 Customer Support Tickets On September 15, 2026, Coinbase CEO Brian Armstrong (@brian_armstrong) recalled an operational crisis during the company's early days in an interview with Bonnie Blockchain (@TheBonnieChang). He shared that a website bug at the time caused some users' account balances to display incorrectly. With a team of only about 5 people, the number of unresolved customer support tickets quickly piled up to between 10,000 and 20,000, sparking a wave of complaints on social media platforms. Armstrong mentioned that his personal phone number was later leaked online, leading to a flood of calls. The team had to work around the clock for several days to fix the issue.
