On Monday, I broke the news that the legal tech company SixFifty, of which a majority was owned as a subsidiary of the Silicon Valley law firm Wilson Sonsini Goodrich & Rosait, had been acquired by the payroll and HR company Paychex.
Although the deal had closed in May, neither Wilson Sonsini nor Paychex publicized it. They also did not respond to my requests for comment. I was able to confirm the deal through a corporate document and a source with knowledge of the deal.
Today, however, the law firm issued a press release about the deal. It still did not name Paychex as the purchaser, saying only it was a “leading human capital management company.” Here is what it said:
Wilson Sonsini Goodrich & Rosati, the premier provider of legal services to technology, life sciences, and growth enterprises worldwide, today announced the successful completion of the sale of its legal technology subsidiary, SixFifty Technologies, LLC (“SixFifty”) to a leading human capital management company. While the terms of the transaction remain confidential, the acquisition ranks among the largest involving a law firm technology asset.
Founded in 2019 by noted legal technologist Kimball Dean Parker in Utah’s vibrant Silicon Slopes, SixFifty was established in partnership with Wilson Sonsini to combine the firm’s deep legal experience with innovative automation technology, helping businesses obtain cost-effective, high-quality legal compliance and risk management solutions. The digital platform leverages AI to facilitate research of employment laws from a proprietary content legal library to provide ready-to-customize compliance and business documents based on the latest regulations.
“SixFifty was launched with a bold vision—to harness technology to assist businesses navigate legal and compliance challenges,” said Doug Clark, managing partner of Wilson Sonsini. “Its strong trajectory and market impact reflect that vision in action. As SixFifty enters this next phase under new ownership, we’re confident it is well-positioned to scale its reach, accelerate innovation, and continue offering smart, tech-driven solutions that meet the real-world needs of businesses today.”
Clark added, “Meanwhile, at Wilson Sonsini, we remain committed to leading the charge—driving meaningful change, advancing cutting-edge ideas and technologies, and pushing the boundaries of what’s possible in the industry.”
SixFifty’s platform supports a wide range of essential business compliance workflows—including offer letters, employment agreements, non-disclosure agreements, independent contractor agreements, arbitration clauses, non-compete and non-solicitation agreements, proprietary information and invention assignment agreements, separation agreements, and more. It allows for customization of documents based on specific needs, including addressing different U.S. states and local jurisdictions.
“We introduced SixFifty to break down barriers to legal access through automation—putting trusted employment-related resources and guidance at the fingertips of businesses of all sizes,” said Parker. “Our platform helps HR and legal teams tackle complex, multi-state compliance with greater speed, confidence, and efficiency. I’m proud of what we’ve built and deeply grateful to Doug for his leadership and belief in what we set out to accomplish—both of which made this next chapter possible.”
