A panel hosted by online hospitality service Airbnb and the National Bar Association, the nation’s oldest and largest national network of African American attorneys, on Tuesday said tech firms and other big employers are taking steps to require outside law firms to be more diverse and inclusive, but more needs to be done.

The event titled “Tech Meets Law: Diversifying Representation,” hosted by Julie Wenah, community operations counsel of Airbnb Inc., and other panelists at the 94th annual NBA convention in New York City, asked attendees, who included lawyers from large and small firms as well as corporate law departments, to brainstorm ideas on how to increase minority representation at law firms.
