# Nudje

> Smart anti-churn and retention inbox for B2B SaaS founders. Catches revenue moments in your product (usage dropping, power users gone quiet, pricing visited multiple times, payment failures, onboarding stalled) and turns them into one-click actions in your inbox. Replaces Customer.io + Mixpanel + Zapier for solo and small SaaS teams. Free forever to start, Pro $49/mo, Scale $149/mo.

Built and operated by UPSID SAS (France). Data hosted in the EU (Supabase Frankfurt). AI generation runs on Mistral (European LLM). GDPR compliant.

## Comparisons
- [Nudje vs Customer.io](https://nudje.io/vs/customer-io): founder-driven retention inbox vs enterprise marketing automation
- [Nudje vs Mixpanel](https://nudje.io/vs/mixpanel): action layer vs analytics dashboard
- [Nudje vs HubSpot Marketing Hub](https://nudje.io/vs/hubspot): focused tool vs all-in-one CRM

## Trust and security
- GDPR compliant (UPSID SAS, France, full sub-processor disclosure)
- EU data residency (Supabase Frankfurt, your data stays in EU)
- Encryption everywhere (TLS 1.3 in transit, AES-256 at rest)
- Sub-processors: Supabase, Cloudflare Workers, Mistral AI, Stripe, Resend, Inngest, Sentry, Crisp
- We do NOT carry SOC 2 or ISO 27001 audits yet (we are honest about this)

## Plans
- Free: $0/mo forever, 100 Actions, 500 customers, 1 seat, unlimited moments, full Customer 360 + AI insights
- Pro: $49/mo or $490/yr (save 17%), 1,000 Actions, 10,000 customers, 5 seats, priority support, early access
- Scale: $149/mo or $1,490/yr, 5,000 Actions, 50,000 customers, 25 seats, custom moments coaching, dedicated Slack

## Use cases
- Anti-churn detection (cancellation page visits, usage drops, support tickets spike, payment failures)
- Upsell signals (pricing visits, plan limits hit, multi-seat opportunities, expansion revenue)
- Activation milestones (first event, first nudge sent, key feature first use)
- Engagement (consistency streaks, ghost user comeback, NPS signals, champion identification)
- Retention nudges for B2B SaaS founders who want personal one-click outreach, not mass campaigns

## Differentiators
- Inbox over dashboard: surfaces the next action, not the next report
- Personal voice: AI drafts founder-style messages, not branded marketing copy
- Founder pricing: $0 to start, $49/mo Pro — no enterprise contracts, no annual commit
- 5-minute setup: API key + one moment, send events, get nudges
- European stack: Mistral AI + Supabase Frankfurt + GDPR-first
