onboarding_stalledThe problem
Your best customers leave quietly.
By the time you notice, they're gone.
Churn shows up in your MRR, not on your calendar. The warning signs were there weeks ago, buried in data you don't have time to read.
You write the same email twelve times a month.
From scratch, manually, when you happen to remember.
Upsells slip by.
Someone hit your plan limit twice this week. You never reached out.
Usage dropped, and no one told you.
A power user goes quiet for three weeks. You find out when they cancel.
The magic
Describe your product. Nudje sets up your whole retention system.
No rules to wire, no dashboards to configure. Tell Nudje what you do in one sentence and its AI turns on the right moments to watch, then hands you a tracking plan to paste in. Minutes, not weeks.

Why Nudje
Built for founders, not enterprise CS teams.
Gainsight needs a team and a six-month rollout. Customer.io needs you to build the campaigns. Churnkey only acts once someone clicks cancel. Nudje's AI does the work, and costs what a founder can actually pay.
For the solo founder who is also the entire customer success team.

Frequently asked questions
What is Nudje?
Nudje is an AI-powered customer retention and expansion platform for B2B SaaS founders. It connects to your product data, detects churn-risk and upsell signals automatically, and generates ready-to-send personalized messages you approve from an inbox or Slack.
How does Nudje reduce churn?
Nudje watches every customer for the early signs of churn, usage dropping, a power user going quiet, a renewal at risk, and flags them while there's still time to act. For each one it drafts a personal message you can send in a click, so at-risk customers hear from you before they decide to leave.
Does Nudje send messages automatically, or do I stay in control?
You stay in control. Every Nudje lands as a draft you review, edit, and approve from your inbox or Slack. You can auto-approve specific moments once you trust them, but nothing goes to a customer without your say-so by default.
How is Nudje different from Churnkey, Gainsight, or Customer.io?
Churnkey acts at the cancel screen, Nudje catches churn weeks earlier, before anyone clicks cancel. Gainsight is an enterprise CS suite that needs a team and a long rollout. Customer.io makes you build the campaigns. Nudje sets itself up from one sentence, catches churn and expansion, and writes the messages for you, at founder pricing.
Does the AI write good messages? Can I edit them before sending?
Yes. Nudje drafts in your voice, grounded in what actually happened in the customer's account, not generic marketing copy. Every draft is fully editable inline before you approve, and you can regenerate it if you want a different angle.
How does Nudje connect to my product?
Send events with our SDK, or pipe them in from PostHog, Segment, or Stripe. No data pipeline? Import a CSV to get started. Setup takes about five minutes.
Is my data safe? Where is it stored?
Your data is hosted in Frankfurt and stays in the EU. Everything is encrypted in transit and at rest, GDPR-compliant, and your data trains no models. We don't carry SOC 2 or ISO 27001 audits yet, and we're upfront about exactly how we handle your data.
How much does Nudje cost?
Free forever to start, no credit card. Pro is $89/mo and Scale is $279/mo. Plans scale with your customer count and usage, see the pricing page for the full breakdown.
