From hero-led CS
to system-led CS.
I build the operating systems behind scalable Customer Success — playbooks, health signals, lifecycle infrastructure, and the team rhythms that turn CS into a defensible revenue lever. 10+ years across post-PMF SaaS in health-tech, ed-tech, and marketplace platforms.

The Scalable CS
Flywheel.
CS scales when each stage compounds the next. Most teams optimize one stage at a time. My edge is operating the full loop — and instrumenting it so the system gets stronger every quarter.
Experience
Onboarding designed around the moments people remember — welcome, first milestone, first success. Time-to-value as a system, not a ticket.
Trust
Health scoring, executive cadences, and proactive risk reviews so customers feel seen before they feel friction.
Retention
Renewals run on signal, not surprise. Forecast confidence at the account level. Save motions triggered by behavior, not gut.
Growth
Expansion playbooks aligned to product usage. CSM + AE motions that compound — not compete.
Reinvestment
What works gets codified. Playbooks, enablement, tooling. The team gets faster every quarter — not bigger.
Results
Best-in-class SaaS metrics: 110%+ NRR, 92% retention, forecasts within 5% variance. CS as a defensible revenue lever.

Onboarding built around moments that matter.
Redesigned onboarding using behavioral science (peak-end rule) plus structured handoffs and CSM enablement. +35% adoption in 6 months; adopted as benchmark post-acquisition.

Pulse — the CS command center, built end-to-end.
A live dashboard that encodes how I think about CS operations: multi-factor health scoring, renewal forecasting, an insight engine, and two views (leadership + CSM) over one dataset.
"Drove best-in-class SaaS metrics — including >90% retention and >110% NRR. I'd work with Lynell again in a heartbeat."
