  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 2 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by RefoundAI on GitHub. Read the source before you install it.

Installation

Install the Founder Sales AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/RefoundAI/lenny-skills.git /tmp/lenny-skills
mkdir -p .claude/skills
cp -r /tmp/lenny-skills/skills/founder-sales .claude/skills/founder-sales
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Founder Sales in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Founder Sales on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Founder Sales is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Founder-Led Sales

Master the art of personally selling your product to build trust and find product-market fit.

Help the user with founder-led sales using insights from 6 guests and posts across Lenny's Podcast and Newsletter.

How to Help

  1. Assess Readiness - Determine if you have enough product validation to start direct selling or if you are hiring a salesperson too early.
  2. Refine the Pitch - Help draft and iterate on the founder-led narrative and value proposition based on subject matter expertise.
  3. Sales Motion Design - Design a high-volume discovery and closing process tailored for early-stage feedback loops.
  4. Overcome Psychological Barriers - Address common hurdles like the fear of asking for money or managing introversion in a sales context.

Core Principles

Leverage Founder Status

Jen Abel: "And founder led sales is really, really, really important because in the very, very, very early days, when there is no brand equity, when there is no marketing engine running, when there is limited to no reference ability, the founder is the product, right? Because the product is still, could be abstract, could be an MVP or in it's really early formation. So the founder is the product."

Use your unique subject matter expertise and novel vision as the primary driver for sales because early products cannot yet sell themselves on features alone.

Treat Sales as a Discipline

Pete Kazanjy: "The thing that I just like to encourage founders and product managers and what have you is just don't be afraid of sales. There's a lot of people out there who would love to tell you a story that it's magical or like, "Oh, you've got to be a born seller," things like that and it's really not."

View sales as a learnable, operational discipline consisting of measurable behaviors rather than an innate talent or magical gift.

Make the Direct Financial Ask

Jason M Lemkin: "Work up your courage, and find how to ask for next steps and money. What would it take, Lenny? How can we get going on Riverside? What would it take?"

Transition from technical problem-solving to a direct request for a financial commitment to validate real intent and move the deal forward.

Lead High-Volume Discovery

Raaz Herzberg: "Wiz is a B2B product, the buyer is the CISO, the people, the person that owns basically security for the entire company. So we would have 10 to 15 meetings every day, with potential customers."

Conduct the discovery process yourself at high volume to develop deep customer empathy before attempting to outsource the process to others.

Build Human Trust

From "How today's fastest-growing B2B startups turned their early users into paying customers": "Frederic (my co-founder) and I personally sold them. Really it was looking then in the eye and getting them to trust us that it would work and be valuable. It was hard. A real grind in the beginning."

In the early days, you are selling yourself and your reliability because customers need a high-trust relationship to adopt an unproven product.

Questions to Help Users

  • "Have you personally closed at least 5 to 10 customers without the help of a dedicated salesperson?"
  • "What is the biggest objection you hear when you tell prospects the price of your product?"
  • "How many discovery calls are you currently conducting per week?"
  • "Are you comfortable asking for a specific financial commitment at the end of a demo?"
  • "What specific insights have you gained from sales calls that were not apparent during initial user research?"

Common Mistakes to Flag

  • Hiring sales too early - Delegating sales before you have a repeatable playbook often leads to a failure to understand why customers actually buy or why they churn.
  • Playing the feature game - Focusing on a list of product features instead of the founder vision and the prospect high-level business pain results in lower conversion.
  • Avoiding the commercial ask - Spending too much time in discovery mode without ever asking for a signed contract prevents you from seeing if anyone will actually pay for the solution.
  • Relying only on friendly intros - Failing to test the pitch on cold parties means you are not getting honest feedback on whether the value proposition stands on its own.

Frequently asked questions

What does the Founder Sales AI skill do?

Help users master the transition from product development to active selling by leveraging their unique status as founders to bridge the trust gap and define a scalable sales motion.

Why use Founder Sales on TypingMind?

Because you install it once and use it with any model. Founder Sales is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Founder Sales in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/RefoundAI/lenny-skills/tree/main/skills/founder-sales. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Founder Sales?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Founder Sales?

As many as you like. As long as a model supports skills, you can use Founder Sales with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Founder Sales AI skill free?

Yes. It is published on GitHub by RefoundAI under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
