Unicorn payments company founded by two Irish brothers in Silicon Valley nine years ago continues to gain value. Limerick brothers Patrick and John Collison’s Stripe is now believed to be worth more than $22bn after the company raised an additional $100m in funding. The new investment came from Tiger Global, which previously led a $245m funding round that valued Stripe at $20bn in September 2018. Stripe is currently deploying a new engineering hub in Singapore to join its existing network of hubs, which includes Dublin, Seattle and San Francisco. The Dublin engineering cohort currently employs more than 100 people.
