Our home grown Innovation Taskforce nurtures our culture of intrapreneurship.

Technology will not replace lawyers, but it will augment us. We focus on creating a hybrid workforce where technology can complement the skills of our lawyers, making sure they are the smartest in the room. We believe that a lawyer with a tool is better than a lawyer on their own, which is why we strive to create tech enhancements that benefit our people, giving them more time to be in the spotlight of the action and apply their expertise where it counts.

We know that innovation is at the forefront of many law firms’ agendas, but what makes Weil different? We give everyone a voice. Whatever their role, whatever their department, we empower all employees to put their hand up and say “We can do something better.” Everyone is powered to innovate, whether they come from a technology background or not.
