## What it does

The skill runs four steps: assess whether your product and market fit a self-serve motion, audit the data and experimentation setup, map the user journey, and find where manual sales or marketing steps can be replaced by product flows. Then it picks the funnel stage with the most friction. The principles come from Lenny's Podcast and Newsletter, drawn from 9 guests, plus a list of self-check questions and common mistakes.

One section argues that a free tier is an acquisition strategy rather than a monetization plan, and shows how to sample paid value inside the free workflow. The skill is blunt about limits: if your product needs heavy customization before a customer sees value, or you sell to a handful of large companies, a pure self-serve motion will stall revenue. Worth checking against your own model before rebuilding the funnel.

Another frequent failure it flags is launching a free version with no automated onboarding and no data on where users drop off. Install with `npx skills add RefoundAI/lenny-skills --skill plg-fundamentals -a claude-code`; the skill file lands at `~/.claude/skills/plg-fundamentals/SKILL.md`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill plg-fundamentals -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/plg-fundamentals/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/plg-fundamentals/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill plg-fundamentals -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/plg-fundamentals/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill plg-fundamentals -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/plg-fundamentals/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install RefoundAI/lenny-skills plg-fundamentals
```

2. **Manually: put the files in place**
- File: `.github/skills/plg-fundamentals/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill plg-fundamentals -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/RefoundAI/lenny-skills --path skills/plg-fundamentals
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/plg-fundamentals/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add RefoundAI/lenny-skills --skill plg-fundamentals -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- judge whether a product suits a self-serve motion
- find the funnel stage with the biggest drop-off
- replace repetitive sales tasks with product flows
- sample paid value inside the free user workflow
- check whether the data foundation can track user behavior

## Example prompts
- Walk me through whether our product fits product-led growth
- Which funnel stage has the most friction and what should we automate first
- List the common mistakes when launching a free version

# PLG Fundamentals

Transform your product into the primary engine for distribution, activation, and expansion.

Help the user with plg fundamentals using insights from 9 guests and posts across Lenny's Podcast and Newsletter.

## How to Help

1. **Assess Viability** - Determine if your product and target market are suited for a self-serve motion based on complexity and volume.
2. **Audit Infrastructure** - Evaluate the data and experimentation tools needed to track and influence user behavior without manual intervention.
3. **Map the Journey** - Identify where manual sales or marketing steps can be replaced by automated product experiences.
4. **Prioritize Levers** - Focus initial efforts on the funnel stage with the highest friction, whether that is acquisition, activation, or conversion.

## Core Principles

### Product as the Primary Vehicle
From "Five steps to starting your product-led growth motion": "At its core, product-led growth (PLG) is about leveraging your product to acquire, activate, convert, retain, and monetize your user base. In PLG, your product is not only the set of features that solve customer pain points but also your go-to-market (GTM) motion, and your distribution and engagement channel."

Success requires shifting from the mindset that sales and marketing drive growth to one where the product handles distribution and revenue generation.

### Workflow-Integrated Value Sampling
Albert Cheng: "What if we actually sampled a number of different paid suggestions and interspersed them to free users across their writing? All of a sudden, people were seeing Grammarly as a much more powerful tool than they were before."

Rather than keeping features locked behind a paywall, demonstrate the potential of paid tiers by interspersing premium value directly into the free user workflow.

### Automation of Repetitive Sales Tasks
Laura Schaffer: "I've noticed this pattern where I'm repeating things over and over again and they're asking the same thing. I think we should put that online. I think we should make that available so they can just see it and then buy it, because we had an online checkout process."

Identify frequent, manual interactions that sales teams perform and digitize them into self-serve product flows to increase efficiency.
