Ajax uses AI to automate timekeeping for law firms. Over 200 firms are paying customers, 14 of them have angel-invested their own money, and our net dollar retention is 140% - firms that start with a handful of seats keep adding more.

After the pilots convert, though, there's not currently anybody at Ajax whose whole job is to proactively roll out more deeply to those firms, introduce them to new features, manage their renewals, and make sure they're being taken care of. Our Activation team runs the pilot and the rollout, and keeps tabs on the firms afterwards, but we have a lot of pilots (we're growing fast).

You'll be the first person whose whole job is to nurture our existing customers, build tooling to proactively monitor their happiness, and keep them coming back to Ajax every day. If you do a great job, you'll be responsible for millions of dollars of retention, expansion, and upsells, and will have a chance to build out the function.

You'll report directly to Jack, the co-Founder (GTM) and co-CEO.

Location

Mon-Fri in NYC HQ (we work best shoulder-to-shoulder). If it sounds fun to you, we'll also happily pay for you to travel and see customers in person.

About Ajax

Lawyers track their time in 6-minute increments. Lost billables cost them $100B a year. Ajax captures everything a lawyer works on and turns it into polished time entries. Firms find revenue they didn't know they were missing, and the worst part of a lawyer's day gets 90% better.

We're the best product in a competitive market. We've won every head-to-head pilot we've ever entered with a competitor, and 97% of firms that pilot Ajax go on to keep it.

Why this role is critical

Our customers are our best growth channel, and no one at Ajax owns it. Almost 50% of our new firms come from referrals and word of mouth. That happens because lawyers love the product, and it happens without us asking. You'll make that an intentional motion.

There's a lot of expansion potential within our existing firms. Law firms are organized by practice areas, each run by specific partners. Often, one practice area will use and love Ajax, but another won't have heard of us. You'll help us win over the entire firm.

What you'll do

• Run regular check-ins. QBRs with bigger firms, lighter-touch for the rest. You'll create the cadence, run the calls, and PM any product improvements that emerge from them.

• Grow the accounts. You'll drive seat expansion, term extensions, upsell, and renewals.

• Roll out new products. We ship new features constantly, and need a way to make sure our thousands of users hear about and adopt them. You'll own that adoption lifecycle.

• Build monitoring. You'll own creating tools that alert us to problems before they happen, notify you of opportunities, and speed the entire team up.

• Decide what we should build. You'll hear the same request from five firms before anyone else does, which means you're one of the key voices in the room when we decide what belongs on the roadmap.

Who you'll be working with:

• Jack Weinberger Founder, GTM (Yale, PE, Chief of Staff at Humming Homes)

• Alex Weinberger Founder, Eng. & Product (Amazon, Founding Eng. at dub)

• Roger Jin - Founding Senior ML Engineer (Harvard, Carnegie Mellon, nference)

• Sophia Fein - Founding Customer Activation (Mintz Levin, KPMG)

• Tyler Argov - Founding Customer Activation (Investment Banking Analyst at Raine)

• Brandon Schneider - Founding Customer Activation (Litigation at Mintz Levin, startup)

• Caleb Sussman - Founding Customer Activation (UChicago, Strategy at Ares Management and BNY)

• Danielle Hughes - Founding Customer Activation (Georgetown CS, FTI Consulting)

• Andrew Sheeler - Full Stack Engineer (Harvard, AngelList)

• Nat Fernelius - Full Stack Engineer (ML at EY)

• Andrew Emil - Full Stack Engineer (Google, Co-founder at Xent Labs)

• David Esterlit - Account Executive (Princeton, founded and sold his own furniture wholesaling company)

• Dillon Lemire - Founding Account Executive (BD Team Lead at Luminance, Systems Engineer at Lockheed Martin)

• Tajus Gopal - SDR (Rippling)

Who you are

You'd rather write the playbook than inherit one. This is a founding role; you'll be inheriting a lot of happy customers, but will have to build much of the process yourself.

Managing partners will take you seriously. Our customers are lawyers; they're skeptical and sometimes argumentative. You'll need to communicate with poise, clarity, and kindness.

You can build your own tools. If you need a dashboard or automation, you're not afraid to create it. You'll have access to Claude Code / Codex, n8n, Zapier, and whatever else you need.

You're comfortable closing. You'll be running retention, which means you'll be negotiating.

You can keep a lot of plates spinning. 200+ firms means deciding where to spend your own time and energy, then not dropping any balls.

Comp

• Cash: $150-200k OTE (80% base, 20% performance bonus)

• Equity: 0.25-0.45% - a founding-hire grant at a company with strong product-market fit and accelerating revenue

• Benefits: Medical, dental, vision, unlimited PTO, Wellhub, subway/bike fare for commutes, team dinner on Weds and free lunch Fridays, flexible hours, 4 WFH weeks / year

What working at Ajax is like

We're 14 people and we work in-office. GTM and engineering sit next to each other and eat lunch together. Our founders are brothers - Jack runs GTM, Alex runs engineering. Our parents were lawyers, so we grew up around this problem.

We work hard, we win as a team, and at least once a week, a customer tells us we've changed their life and refers a friend. If that sounds fun, we'd love to have you join us!

Hiring process
