Law is changing fast - join us on the journey to build an OS for the law firm of the future.
We're growing faster than we can handle. Every day, 5+ users tell us the app has changed their life. We work hard, we learn from each other, and we have fun doing it.
If that sounds fun, come join us!
Lawyers track their time in 6 minute increments. Lost time costs them $100B/year.
Ajax is founded by Jack and Alex.
Ajax is founded by two brothers (and occasional sparring partners), Jack and Alex. As children of lawyers and growing up Jewish in NYC, half their friends are lawyers. When they first mentioned the idea to their Dad, he recalled the exact matter codes that he had billed for in his first law job over 30 years ago.
Starting a business.
Before starting the business, they interviewed 150 lawyers in a month to make sure they had strong conviction that time tracking is insanely painful and hard to automate - a good space to solve problems.
Ajax today.
Today, Ajax uses AI to automate timekeeping and make lawyers’ days suck less. Soon, we’ll use Ajax data to automate reporting, manage profitability, win clients, and more.
These are a few things we’re proud of
Of firms that pilot convert into paying customers
Customers expressed their love. i.e. "I'm leaving my husband for Ajax"
Customers have angel-invested after trying the product
We’re a tight, fast-moving team that strives to be the most customer-obsessed startup in the world.
