Customer Success and post-sales are at an inflection point. Not a gradual evolution — a structural break. The motion that defined the function for the past decade is being replaced in real time, and the professionals who built careers inside that motion are being asked to reinvent themselves while still doing the job.
The forces driving this are not theoretical. Outcome-based and consumption pricing models are replacing seat-based SaaS contracts, making value realization a contractual obligation rather than a best practice. Forward Deployed Engineers are appearing inside post-sales orgs, blurring the line between technical implementation and customer success. AI is compressing the work that used to require a team of CSMs into a fraction of the headcount — and simultaneously raising the bar for the human judgment that remains.
The inflection has already happened. The question is who will lead through it.
