With the ink barely dry on one fundraising effort by Bolt, a firm that makes e-commerce checkout software, the startup is already pitching investors on a new round.

Shortly after raising nearly $400 million at an $11 billion valuation in a Series E funding round, according to three people familiar with the matter, Bolt is seeking another nearly $400 million funding round at an even higher valuation of $14 billion, said two of those people. If it succeeds in raising the new round at that valuation, it will indicate intense investor enthusiasm for Bolt, an emerging leader among firms that offer one-click checkout technology tailored to merchants who don’t sell their wares on Amazon.

In an interview with The Information, Bolt CEO Ryan Breslow declined to comment on the latest fundraising rounds. The company’s past fundings, he said, “may seem like a lot of money compared to most early-stage startups, but we’re playing in a space with a lot of very well-funded folks.”
