Checkout.com, a London-based payments solutions provider, announced that it closed a $450 million Series C fundraising round giving it a post-money valuation of $15 billion. The Series C was led by Tiger Global Management, LLC, a New York-based technology investor. Greenoaks Capital also joined the round along with participation from existing investors Insight Partners, DST Global, Coatue Management, Blossom Capital, Endeavor Catalyst, and Singapore’s Sovereign Wealth Fund GIC. While Checkout.com‘s profits from current operations will continue to be reinvested to power future growth, the new funding will be used to further grow its balance sheet and drive new innovative opportunities.
