AI-powered time-tracking for lawyers
Ajax is on a mission to help law firms capture and organize their latent knowledge and put it to work. The legal services industry takes in over $1T in annual revenue and boasts 1.5 million practicing attorneys just here in the US, but AI has clients wondering what exactly they're paying so much for.
These clients are half-right: AI makes it faster to draft rote motions and review voluminous documents during discovery. But law firms have never been in the business of mutating and transmitting documents; they're paid to apply their firm's institutional knowledge and best practices to their clients' specific cases. Ajax automatically captures this knowledge and helps firms redeploy it toward faster, cheaper, and more effective legal services.
Our mission is lofty, but our product provides tangible, day-1 benefit to firms. We started by addressing the firm’s core revenue driver: our AI timekeeping product tracks attorneys' work and draftsbillable time entries for them, finding each attorney tens of thousands of incremental dollars per year. This product has 5x annual growth, hundreds of law firms, and thousands of DAUs.
Metrics we’re proud of We’re solving the worst problem 1.5 million attorneys in the US face. Our metrics are exceptional:
Customers say things like "I'm leaving my husband for Ajax" (really)
14 customers have invested in Ajax with their own money
<1% Customer Churn: we build long term partnerships with our customers (<10% annual is considered good)
97% Pilot Conversion Rate: when we start pilots, we win them (>70% is considered good)
140% Net Dollar Retention: after firms convert with Ajax, they share it with more and more employees (>120% is considered good)
Your core job here is to build software that makes owning and operating a law firm as easy as pie.
By day 30, you will
Ship user-facing features that make reviewing one's time easier, e.g.:
Automatically proposing UIs that match users' review preferences, or
Rethinking how we enable users to split entries
Build a new billing system integration that unlocks more of the legal market
By day 90, you will
Generate meaningful improvements to our pipeline's quality, e.g.:
Improving our clustering algorithms
Driving down p99 latency
Meet with customers and prototype a new feature, e.g.
Building an ontology for the firm's client-management and exposing it via MCP
By day 180, you will
Shape our product roadmap. You'll work with Alex (me) to decide what problems we need to solve, and go solve them
Ownership: a wise man* once said the difference between senior engineers and junior engineers is that senior engineers own the feature into production and beyond
Empathy: to build features end to end, you must be able to sit in our customers' shoes. Our company makes bs work go away for lawyers that work really hard; that needs to speak to you.
Resourceful: you're scrappy: you prefer figuring bugs out yourself to putting your hands up.

Your reward function is customer happiness (stolen verbatim from our 2nd engineer).
You want ownership - that means shipping your ideas and owning the results.
You like adventure. We’re solving an unsolved problem, so we need to be brave and rigorous in our exploration. The optimal number of unsuccessful experiments is higher than 0.
I like working here because we win a lot, we’re solving previously-intractable technical challenges, and at least once a week a customer tells me that our product is saving their life. If that sounds fun to you, send me an email.
How far along are we?
Can I work remotely?
We usually work 5 days/week in-person in FiDi, NYC. We’re flexible, though, and we get that people are adults - Tyler worked from home when he had some family staying over, and Nat took a Wednesday off recently because she had to take delivery of a rare fish (don't ask).
Compensation: $210-$270k base + .25%-.75% equity.
The range is wide because we’re open to a range of seniorities.
Offers may extend above but will not dip below the stated range.
We also offer unlimited PTO, paid lunch/dinner on Fridays, and health/dental/vision.

Ajax provides AI-powered time-tracking specifically for lawyers, designed to remove the burden of timekeeping from their day. The product automatically captures billable hours and activities so lawyers don’t have to manually log time, using AI to understand work activity and associate it with matters and clients. How it works: The system integrates with lawyers’ workflows and apps to monitor activities and generate time entries automatically, with options to review and edit entries before submission. Differentiation: Unlike general time-tracking tools, Ajax targets the legal industry and focuses on automating time capture for legal work, reducing administrative overhead and the risk of missing billable hours, while aligning with law-firm billing practices. Goal: To free lawyers from manual timekeeping, improve billing accuracy and efficiency, and streamline the path from work to client invoices.
