AI for customer success that scales relationships without scaling headcount
Runs onboarding, lifecycle touches, and renewal sequences in your CS voice.
Pulls customer health scores and flags churn signals before they hit.
Brain AI holds your product, customer base, and CS playbook.
Every customer success workflow in one platform
Customer success runs on relationships and on the lifecycle work, health monitoring, and renewal cadence behind them. Sintra runs the lifecycle layer for you. Twelve specialised functions across onboarding, retention, expansion, and renewal, all sharing your product and customer base through Brain AI.
What slows down customer success
AI for customer success should compound CSM capacity, not duplicate the CRM. These are the drains every team runs into.
Onboarding falls off
Day-one activation high. Day-thirty activation drops. The lifecycle programme never quite ships.
Touch frequency is inconsistent
Big accounts get weekly. Small accounts get quarterly. Both should get more.
Churn signals get caught late
Customer disengages. CSM notices three weeks later.
Renewal conversations start too late
Renewal date hits. CSM scrambles. Negotiation suffers.
Expansion conversations don't happen
Customer shows expansion signal. CSM is heads-down on saves. Opportunity passes.
QBR prep eats Tuesdays
Each QBR needs custom materials. The prep eats the week before.

How CS teams actually use AI for customer success
Five workflows that move CS from reactive to systematic.
Onboarding
AI runs the onboarding sequence: welcome, activation nudges, feature highlights tied to behaviour.
Lifecycle touches
AI runs proactive touches at the right milestones: 30-day check-in, expansion triggers, renewal nudges.
Churn prevention
AI catches churn signals in real-time, drafts the right intervention, and queues it for CSM review.
Renewal cadence
AI starts renewal conversations 120 days out. The conversation happens at the right moment.
QBR prep
AI builds per-customer QBR materials: usage data, health score, expansion opportunities.
