# Come build with us.

**About us:** Lawyers track their time in 6 minute increments. Lost time costs them $100B/year.

Today, Ajax uses AI to automate timekeeping and make lawyers’ days suck less. Soon, we'll use data Ajax _already processes_ to automate reporting, manage profitability, win clients, and more.

**Things we're proud of:**

Our ARR is doubling every 3 months, 97% of firms that piloted Ajax last year subscribed, and we've _never_ churned a paying customer.

Every day, users tell us things like "I'm leaving my husband for Ajax", "this app saved my life", and "I'm in love with Ajax - and not the cleaning product!" 12 customers have angel-invested after trying it.

**Come join us!** If you like solving problems with a tight, fast-moving team, let's talk!

## Team Highlights

Siyou Pei

Product Engineer

Joined Ajax in July 2025

### What is your favorite project since joining Ajax?

`I actually have two:`

`(1) a next.js rewrite that made the app feel instantaneous: we rearchitected the UI and reduced interaction latency by 60+%, even with hundreds of entries and thousands of components on the page`

`(2) shipping a recent activities panel that updates automatically via postgres WAL replication: this real-time “domino’s pizza tracker” style panel assures even the most contemporaneous billers that Ajax is capturing their work in real time.`

### What is your engineering superpower?

`Combining product design and engineering to solve end-to-end comprehensive problems :)`

### Anything else to add?

`Nothing is greater than building meaningful stuff. We really care about the product and it feels so great to really make customers' lives easier.`
