More than 170 general counsel and corporate legal officers have signed an open letter to big law firms, lamenting new partner classes that “remain largely male and largely white.” The letter says their companies will prioritize their legal spend on those firms that commit to diversity and inclusion.

The letter, released Sunday, has been signed by chief legal officers in a variety of industries, including those in technology, retail, media, hospitality and financial services. The companies range from small tech outfits to large corporations, such as Google Fiber, Etsy, Heineken USA, Chobani Global Holdings, Waymo, Lyft, Vox Media, S&P Global Ratings and Booz Allen Hamilton. (ALM Media’s general counsel is also among the signatories.)
