Stripe, the online payments company founded by Irish brothers Patrick and John Collison, has raised $150m (€141m) in new funding, valuing the firm at $9 billion (€8.5 billion).
The Series D round was led by CapitalG and General Catalyst, in addition to existing investors such as Sequoia Capital and others.
The Californian-based company says it will use the money to invest in more developer tools, more software products and to speed up its international expansion.
In a recent interview with RTÉ at Web Summit when asked about future funding options, Stripe’s chief business officer Billy Alvarado said the firm was “very happy as a private company and continue to be focused on being an independent company”, adding Stripe had no plans for an IPO.
The company currently has users in 110 countries around the world.
The last time it raised funding was in 2015 when it took in $100m, valuing the business at $5 billion.
As an indicator of how widely its software is now used, the firm says about half of US internet users have purchased something from a Stripe user in the past year.
The company includes users like SAP, Macy's, Missguided, GE, Adidas, Docusign, Slack, Medium, Daily Mail, Yelp, NASDAQ, UNICEF, and both presidential campaigns, among its list of clients.
Stripe has its European Headquarters in Dublin.
