Venture capital firm Founders Fund has led a new investment in Ramp, a corporate credit card and spending management software startup that is less than three years old, at an $8 billion valuation, including the investment, said two people familiar with the matter.

The deal, initially struck in December, reflects venture capitalists’ continued appetite for certain fast-growing companies despite a spillover from falling public stocks that has prompted other investors to cut offer prices for startup shares—even after founders agreed to a deal. The price of the Ramp deal, which was recently completed, didn’t appear to change as public market conditions worsened.
