## What is Nudje

Nudje is a focused tool for B2B SaaS founders who want to retain customers personally — not run mass marketing campaigns. Customers send product events to Nudje, our rule engine matches events to "moments" (e.g. usage dropping, trial ending, pricing visited), and Nudje drafts a personal nudge ready to send. The founder approves with one click in their inbox or Slack, and the message goes to the customer.

The core opinion: dashboards tell you what happened, Nudje tells you what to do next. Most founders have lost a customer they could have saved — Nudje exists so you catch the signal in time.

## How it works (5 steps)

1. **Send events from your product** — drop the API key, POST events via curl, Node, Python, or any HTTP client. Events are simple JSON: `{ user_id, event, properties }`.
2. **Configure your moments** — pick from the 20+ catalog or build a custom moment in the Wizard (4 steps, no code).
3. **Nudje catches the signals** — the rule engine matches your events to moments in real time.
4. **Review and approve in your inbox** — every nudge lands as a draft message. Approve, edit inline, or dismiss. Slack mirror available.
5. **Customer gets the right message at the right time** — email, Slack, or webhook. Delivered in seconds.

## Moments catalog (full)

### Retention (5)
Catch users before they slip away.

- **When usage starts slipping** (slug: `usage-decline`) — Their activity dropped 50%+ in the last 30 days. Reach out before they ghost. Fires when: Monthly usage dropped 50%+ vs 90-day average.
- **When your champion goes silent** (slug: `power-user-gone-quiet`) — Your best customer hasn't shown up for a week. They're slipping away. Fires when: Top user hasn't logged in for 7 days.
- **After they tried it and never came back** (slug: `feature-abandonment`) — They opened the door, took one look, and left. Find out what broke. Fires when: Used a key feature once, then never again.
- **When they sign up and disappear** (slug: `onboarding-incomplete`) — One week in, still no first action. The signup excitement is fading. Fires when: Signed up 7+ days ago, missed activation step.

### Upsell (4)

### Anti-churn (5)

- **When tickets start piling up** (slug: `support-escalation`) — More than one ticket this week. Frustration is building. Get ahead of it. Fires when: Multiple support tickets in 7 days.
- **When they peek at the cancellation page** (slug: `cancellation-visited`) — They opened the exit door. They didn't walk through. You still have time. Fires when: Visited /cancel page without completing.
- **Before they downgrade themselves** (slug: `downgrade-attempted`) — They started the downgrade. Ask why before they save themselves halfway. Fires when: User started a plan downgrade flow.

- **When they hit a wall in onboarding** (slug: `stuck-on-step`) — Same step for 48h. Either the doc is unclear or they need a human. Fires when: Same onboarding step for 48h+.

### Nudje vs Mixpanel
URL: https://nudje.io/vs/mixpanel

Mixpanel positioning: Product analytics dashboard
Nudje positioning: Action layer for your signals

**Short version:** Mixpanel shows you what happened in your product. Nudje tells you what to do next and lets you do it in one click. They complement each other beautifully.

| Feature | Nudje | Mixpanel |
|---|---|---|
| Primary use case | Act on signals | Analyze events |
| Starting price | $0 free forever | $25/mo (Free tier) · $833/mo (Growth) |
| Setup time | 5 min | 1–2 days |

| Event ingestion | Same JSON shape | Yes |
| Pricing model | Per Action consumed | Per MTU (Monthly Tracked User) |

**Why founders pick Nudje:**
1. **Action over analysis** — Mixpanel is great for analyzing patterns. Nudje is what you wire on top to actually do something when a pattern triggers.
2. **Built for B2B SaaS retention** — Mixpanel covers everything. Nudje is laser-focused on retention and revenue moments for B2B SaaS founders.
3. **Founders, not analysts** — Mixpanel is built for product/data teams. Nudje is built for founders who want to act, not read.

**Migration:** You can use Nudje WITH Mixpanel. Send the same events to both. Nudje acts, Mixpanel analyzes.

**FAQ:**
**Q: Do I need to replace Mixpanel?**
A: No. Many teams use both: Mixpanel for deep analysis, Nudje for the action layer. Send events to both in parallel.

**Q: Can I send Mixpanel events to Nudje?**
A: Yes. Mixpanel and Nudje both accept the same event JSON shape. Configure a destination in your event router (Segment, RudderStack, etc.) to fan out.

### Nudje vs HubSpot Marketing Hub
URL: https://nudje.io/vs/hubspot

HubSpot Marketing Hub positioning: All-in-one CRM + marketing automation
Nudje positioning: Lightweight retention inbox

**Short version:** HubSpot is a massive CRM platform for sales + marketing + service teams. Nudje is one focused tool for B2B SaaS founders who want to retain customers, not manage pipeline.

| Feature | Nudje | HubSpot Marketing Hub |
|---|---|---|
| Starting price | $0 free forever | $20/mo (Starter) · $890/mo (Pro) |
| Target user | B2B SaaS founder | Sales + marketing team |
| Onboarding time | 5 min | 4–8 weeks (Implementation Pro often required) |
| Product complexity | 1 focused tool | 10+ products bundled |
| Annual commit | No commit | Usually required |
| AI-drafted messages | Mistral built-in | Add-on (HubSpot AI) |
| Action-oriented UX | Inbox with one-click | Workflows + sequences (steeper) |
| Event-based triggers | 20+ pre-built moments | Workflow triggers |
| Best for | Founder-led retention | Enterprise sales pipeline |

**Why founders pick Nudje:**
1. **Focused, not bloated** — Nudje does one thing well: catch revenue moments and act on them. HubSpot does 10 things, and you pay for all of them.
2. **Founder pricing, not enterprise** — Get Pro for $49/mo. HubSpot Marketing Pro starts at $890/mo and ramps from there.
3. **Ship today, not next month** — Setup takes 5 minutes. HubSpot typically requires implementation help and weeks of config.

**Migration:** If you only use HubSpot for retention emails, Nudje replaces that in an afternoon. Keep HubSpot for CRM if you still need it.

**FAQ:**
**Q: Does Nudje have a CRM?**
A: No. Nudje focuses on retention nudges, not pipeline management. Use Pipedrive, Attio, or a notion DB for CRM. Nudje works alongside.

**Q: Can I export my HubSpot contacts to Nudje?**
A: Yes. Send your contact list via the Nudje API (POST /v1/customers) as identify events. They become Nudje customers immediately.
