Step by Step

Scroll horizontally. Each step shows what the engine actually does at that moment.

Step 1

Personalized Onboarding

A custom 30-60-90 plan per customer. New accounts reach value sooner, and fewer churn in the first quarter.

Step 2

Health-Score Calculation

Usage, tickets, notes and invoices combine into a real-time score. Risk and expansion plays auto-trigger.

Step 3

Usage Tracking

Product usage flows into one view. Adoption gaps surface. Dormant accounts get re-engaged before they churn.

Step 4

Voice-of-Customer

Calls, tickets and NPS turn into themed insights for product and marketing. Weekly, not quarterly.

Step 5

Expansion Signals

Usage growth, new users, ticket patterns and hiring feed an expansion-readiness score. Hit the window.

Step 6

QBR Preparation

Usage, tickets and revenue turn into a draft QBR deck. 4 to 6 hours of prep collapse into 30 minutes.

Step 7

Renewal Automation

60 days before renewal, a draft proposal lands. Renewal cycles get shorter, and more renewals land on time.

Step 8

Support Deflection

A first-response AI handles the routine tickets. The simple cases self-serve. Humans pick up the hard ones faster.

Questions, answered.

How the CS Engine fits your stack, your data, and your compliance.

How does the CS Engine fit into our existing stack?

The CS Engine runs inside the systems you already use: your CRM (HubSpot or Attio), your product usage data, and your support tickets. Your team keeps working where it works today, with no new SaaS to buy and no extra login to learn. When two tools don't share data, n8n covers the gap between them.

Do we run this ourselves, or is it done-for-you?

The CS Engine is done-for-you. Sondero builds it and operates it inside your own systems; you don't log into a Sondero product or manage it yourself. Nothing ships without a spec you have signed off, and the first workflow is typically live in about two weeks. It is not a self-service SaaS tool you run alone.

Is the CS Engine GDPR-compliant, and where does our data live?

The CS Engine is set up to match your compliance requirements. When you need strict data residency, it can run entirely on German and EU infrastructure. Where you are open to a model provider outside the EU, that step runs under a data-processing agreement with no training on your data. An AVV is ready to sign, GDPR documentation is included, and the working data stays inside your own systems.

What data does the CS Engine need to work?

The CS Engine needs access to three things: your product usage data, your CRM (HubSpot or Attio), and your support tooling, including tickets and NPS or sentiment scores. It combines those into a daily health score for every account, so renewal risk and expansion signals surface early instead of at renewal time.

Does the CS Engine replace our CSMs?

The CS Engine does not replace your CSMs. It flags which accounts are at risk, tailors onboarding playbooks, prepares QBRs, and drafts renewal proposals in your branding, so the routine work is already done. Your CSM still owns the relationship and makes the call; the engine hands them the signal and the first draft.

How is the CS Engine different from just using ChatGPT?

The CS Engine runs on your own account data, wired into your real workflow. It scores account health daily, catches churn signals early, and deflects the simple support tickets so your team handles the hard ones, with Sondero monitoring it through evals and prompt versioning. Asking ChatGPT answers one question; the engine watches every account continuously and flags risk before the renewal call.
