GitLab has confirmed with TechCrunch that it oversaw a $195 million secondary sale that values the company at $6 billion. CNBC broke the story earlier today.

The company’s impressive valuation comes after its most recent 2019 Series E in which it raised $268 million on a 2.75 billion valuation, an increase of $3.25 billion in under 18 months. Company co-founder and CEO Sid Sijbrandij believes the increase is due to his company’s progress adding functionality to the platform.

“We believe the increase in valuation over the past year reflects the progress of our complete DevOps platform towards realizing a greater share of the growing, multi-billion dollar software development market,” he told TechCrunch.

While the startup has raised over $434 million, this round involved buying employee stock options, a move that allows the company’s workers to cash in some of their equity prior to going public. CNBC reported that the firms buying the stock included Alta Park, HMI Capital, OMERS Growth Equity, TCV and Verition.
