Lexion is on a roll. The Seattle startup that helps legal teams use AI to sift through contracts has quadrupled revenue and added 50 customers over the past four months, including brands such as Outreach, Blue Nile, OfferUp, and others. Now the company is reeling in more cash to supercharge growth, announcing a $11 million Series A round led by Khosla Ventures. It’s one of the only Seattle-area startups to land funding from Khosla, a top Silicon Valley firm that has backed giants such as DoorDash, Okta, Opendoor, Square, and others including OpenAI.
