Customer Activation

Get in early at a hypergrowth AI startup and own the customer journey end-to-end!

You’ll get more responsibility than you can handle, guaranteed :-)

• Mon-Fri in NYC HQ (we learn best shoulder-to-shoulder)

Lawyers track their time in 6-minute increments. Lost billables and time cost them $100B/year.

Today, Ajax uses AI to automate timekeeping, find lost billables, and make lawyers’ days suck less.

Soon, we’ll use data Ajax already processes - emails, docs, zooms, calls, browsing, and more - to file emails, automate reporting, manage firm profitability, preempt angry clients, and more.

Stage: We're well-funded, growing rapidly, and well past product-market fit. In the last month alone, we've almost added more ARR than we did in all of 2025.

Team: We're a team of 15 right now. You'll join Sophia Fein, Tyler Argov, Brandon Schneider, Caleb Sussman and Danielle Hughes in the activation role.

You'll drive Ajax's growth: Own the customer experience from pilot through long-term success. We've converted 97% of our pilots, and nearly half of our new customers come from referrals and word of mouth. Your work will directly impact both.

You'll help Ajax scale: Build the playbooks, automations, and processes that allow us to deliver an exceptional customer experience as we grow.

You’ll get room to run

You’ll have broad latitude to remake our processes, and your own role, as we grow. We don’t want rule-followers - we want to hire incredible people and give them lots of room to build.

If you succeed, you will be the reason Ajax grows 10x. Are you up for it?

• Run onboardings/own pilot success: Lead kickoff calls, train users, understand what matters to each firm, and drive pilots to conversion.

• Support customers beyond the pilot: Continue building relationships, driving adoption, and making sure firms are successful long after they subscribe.

• Investigate and solve problems: Dig into technical issues, troubleshoot with customers, and work closely with engineering to turn feedback into improvements.

• Build for scale: Automate repetitive work, create reusable playbooks, and improve the processes that help us onboard and support more firms.

• You have 1-4 years of experience in banking, consulting, high-growth startups, or a similar environment

• Talking to users and solving their problems energizes you.

• You’d rather ship v1 and learn than wait for perfect directions.

• Your curiosity drives you to learn new skills and dive deep into problems.

• You’re comfortable utilizing different AI tools

• You communicate with clarity and kindness, whether to a paralegal or a partner, and you can be persuasive without leaving stakeholders with a sour taste.

• You enjoy turning ad-hoc processes into repeatable systems.

  Imposter-syndrome disclaimer: research shows some candidates avoid applying unless they check every box. If this role excites you, please reach out even if your experience looks a little different.

   

• $140K–$170K base salary + $20K performance bonus + 0.15-0.3% equity. Both are subject to increase if you do a great job.

• Benefits: Medical, dental, vision, unlimited PTO, Wellhub, 401k. subway/bike fare for commutes, team dinner on Weds and free lunch Fridays, flexible hours, 4 WFH weeks / year

• Daily collaboration with founders and a steep growth curve.

• Everything we do is oriented towards earning customers’ love, trust, and referrals.

• You’ll spend lots of time walking users through features, investigating their usage and proactively proposing improvements, and even doing things that don’t scale like sending donuts to power users.

Does this degree of customer obsession exhaust or energize you?

This scenario happens at least once a week:

• A customer reports a bug. You drop everything to investigate and manage to fix it in 4 minutes.

• You email the customer immediately to report that you’ve solved their problem. They thank you effusively for the quick response and say they’re recommending Ajax to a friend at another firm.

Are you comfortable in an environment where velocity is this important?

• We only bring somebody on if we can imagine looking back in 5 years and saying ‘they were the single most important driver of our success.’”

• You will deal with high-stakes situations and be responsible for the outcomes. If you do an incredible job, you’ll be the reason Ajax grows 10x - and your scope will grow along with it.

Do you want such a steep growth curve?

If helping customers succeed and building new processes sounds fun, we’d love to hear from you!
