The Post-Sales Handoff Just Changed
Customer success as a discipline hit a wall. CSM headcount grew 700% through Q2 2022, then stopped. Over the same period, forward deployed engineering roles grew 1,000% and kept climbing. That is not a rebrand. Companies selling AI products discovered that traditional health scores, NPS surveys, and activity tracking do not correlate with retention when the product changes weekly and adoption means nothing without workflow integration.
Ryan Seams at Assembly AI stopped using the CSM title entirely. Technical buyers went defensive the moment they heard "customer success manager." Renaming the role to forward deployed engineer filled a recruiting pipeline that "technical account manager" could not touch. Two candidates in 2.5 months became a full pipeline with no change to the actual job.
What Died: Activity Scores and NPS
Bobby Cooper's data shows more than 50% of CSM activity has zero correlation with retention. NPS scores look clean while renewal rates collapse. Low response rates mean non-responders are often the churners, and there is no clean path from a survey score to an action that changes the outcome.
Harvey, the legal AI platform valued at $11 billion, still runs on-site EBRs and old-school change management. That works because selling AI into a law firm is selling a change in how 30-year partners work, not selling software. Adoption is the starting line, not the finish. A firm can log into Harvey daily without changing how it operates, and that still means churn.
What Replaced It: Outcome Verification
Monica Perez at Lovable replaced Gainsight with a custom command center built on Lovable's own platform. She maintains it like a product with a feature backlog and weekly releases. Her logic: the team closest to the customer should build the tool. Waiting on a vendor roadmap is now the constraint, not the budget.
Lovable uses hundreds of individualized Slack bots, each scoped to a customer's instance, projects, and contract terms. That is high-context support at speed, not standardized playbooks. Perez onboarded during a one-week work trial, then met every customer in her first 30 days. That is a compact, founder-driven motion, not scaled SaaS support.
The Sales Handoff Implication
Weave moved the "closed-won" line into implementation. A deal only counted as booked once the customer hit a success threshold inside implementation, not at signature. That fixed the handoff, aligned sales to qualify better, and took churn from 4% per month to roughly 0.5% while scaling from $8 million to $200 million ARR through IPO.
For AEs closing enterprise deals into AI-native companies, the handoff now includes workflow design, not just contract terms. Your compensation might hinge on implementation milestones, not signature dates. Worth noting: if the post-sales team is called forward deployed engineering instead of customer success, expect technical discovery in the sales cycle and longer ramp periods for deal closure.
