Job Description
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 :-)
LOCATION
- Mon-Fri in NYC HQ (we learn best shoulder-to-shoulder)
ABOUT AJAX
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.
Long-run, 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’ve hit product-market fit, with customers saying things like “this app saved my life”, “I’m in love with Ajax, and not the cleaning product”, and “I’m divorcing my husband for Ajax.” ARR is tripling every ~3 months.
- Team Size: 7 FTEs
- Founding Team:
- Jack Weinberger https://www.linkedin.com/in/jackweinberger/ Founder, GTM (Yale, PE, Chief of Staff at Humming Homes https://humminghomes.com/about)
- Alex Weinberger https://www.linkedin.com/in/alex-weinberger Founder, Eng. & Product (Amazon, Founding Eng. at dub https://www.dubapp.com/)
- Roger Jin https://www.linkedin.com/in/roger-jin-96a12a76/ - Founding ML Engineer (Harvard, Carnegie Mellon, nference https://nference.com/)
WHY THIS ROLE IS CRITICAL
You’ll win pilots - the most important point in the customer journey:
Each new firm runs a pilot before subscribing. They only buy if users understand the app, feel supported, and see their preferences reflected in it. You’ll own the user experience and pilot outcomes.
You’ll drive referrals:
50% of our new sales come from referrals. Your work to make customers love Ajax will fuel this.
You’ll help Ajax scale:
Our pilots reliably get users to an “aha” moment (we’ve won 97% of pilots this year), but it’s high-touch. We run kickoffs, coach users, customize settings, spot issues, build fixes, document ROI, and more.
By writing playbooks, automations, and reports that help us onboard more firms, you have the opportunity to directly double or triple our growth rate.
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?
WHAT YOU’LL DO
- Run onboardings: Run onboarding calls and 1-1 setup calls, coach users on how to use Ajax successfully, and customize Ajax for them.
- Own pilot success: Learn what the firm cares about, spot issues early, implement changes in real-time, document ROI, run closing calls.
- Investigate issues: dive in, fix problems, gather data, and feed insights to engineering so we keep improving.
- Set us up for scale: automate repeated steps, create reusable materials and playbooks, trim anything that doesn’t move the needle.
YOU MIGHT THRIVE HERE IF…
- 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 diving into Excel, and know (or are excited to ramp quickly on) SQL
- 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.
WHAT YOU’LL GET
- $120-160k base + above-market equity. Both are subject to increase if you do a great job.
- Benefits: health, dental, vision, unlimited PTO.
- Daily collaboration with founders and a steep growth curve.
