I'm Jeff Moss. I help people who own customer relationships build the expertise that makes any customer, any company, and themselves successful.

I got my start on the ground floor at SalesRabbit, employee number seven, back when customer success was barely a named thing. I started in support and became the first person there whose whole job was the customer. There was no playbook to copy, so I built the team and the motion from scratch, and I made every mistake there was to make.

And things were not working. We were losing 25% of new customers in the first 90 days while I did everything a customer success person was supposed to do. So I started interviewing our most successful customers, the ones who would stand on stage and say the product changed their business, and asked them how they win. Once I understood that, the whole job changed. I built what I learned into our onboarding, our processes, our tooling.

Then I got to go on the road. Not as a consultant exactly, more as an operating partner. I worked with venture firms and the companies in their portfolios that were in trouble: hemorrhaging customers, growth slowing, no idea why. My job was to get under the hood and fix it.

Over time that became more than 75 companies across wildly different industries: restaurant operations, healthcare, email marketing, time tracking, legal, document management. I implemented playbooks and analyzed over a million customer records, and I stopped thinking about customer success as a department and started seeing it as a discipline.

The same few things mattered every time, in every industry, at every stage. It always came down to knowing exactly how the customer wins, and getting them there in a way you can prove.

For a long time I thought that was the whole finding. It wasn't. The deeper thing was that I could walk into a restaurant-software company one day and a patient-outcomes company the next and figure it out every single time. Not because I'm special. Because the judgment to find the few things that matter is itself a discipline. It can be broken down, practiced, and carried anywhere.
