Fast Checkout is a one-click purchase product for e-commerce. It works on any browser, device, or platform, delivering a “consistent, stress-free” purchasing experience. The start-up makes its money by charging sellers a transaction fee of around 3% to process payments. Its seed round, at $2.5 million, closed in November 2019, with its Series A closing just four months later. The fintech has not disclosed any details as of yet regarding its post-round valuation. It was valued at just $180 million after its $20 million Series A last year after being founded in March 2019 and only launched its core product in September.
