Jessica Jonas
Founder & CEO
Jessica founded William with a clear vision: to solve the legal industry's most frustrating problem—the gap between the work lawyers do and the time they actually bill.
With deep expertise in legal technology and a passion for building tools that make lawyers' lives easier, Jessica leads William's mission to transform how law firms capture, generate, and optimize their billing.
Under her leadership, William has grown to serve AmLaw 200 firms, helping attorneys recover countless hours previously lost to manual time entry.
Our Story
William was born from a simple observation: lawyers are excellent at practicing law, but the administrative burden of tracking and billing time takes them away from what they do best.
Studies show that attorneys lose an average of 2+ hours per day to billing inefficiencies—time that should be spent serving clients. That's nearly millions of dollars in lost revenue per year.
We built William to change that. Using advanced AI that understands legal work, we've created a platform that automatically captures billable activity, generates compliant narratives, and ensures nothing falls through the cracks.
Today, William serves leading law firms across the country, helping them recover revenue, improve accuracy, and give attorneys back their time.
