Lenny Skills is a collection of product-management and engineering workflows for Claude Code and other AI agents, covering areas such as strategy, research, planning, shipping, growth, and hiring. Each skill gives an agent specialized guidance, frameworks, checklists, or templates for product work, and the catalogue contains many of these skills.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.01641 |
| Opus 5 | $0.00017 | $0.00821 |
| Sonnet 5 | $0.00007 | $0.00328 |
| Haiku 4.5 | $0.00003 | $0.00164 |
Grade A, and why
fundraising scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Startup Fundraising and Exits
Master the art of raising capital, managing investor relations, and navigating strategic acquisitions.
Help the user with startup fundraising and exits using insights from 15 guests and posts across Lenny's Podcast and Newsletter.
How to Help
- Assess Capital Needs - Help the user determine if they should bootstrap or raise venture capital based on their market ambition and business model complexity.
- Refine Narrative and Materials - Guide the user in building a compelling why now narrative, a structured pitch deck, and a targeted investor list.
- Execute the Raise - Provide a tactical schedule for outreach, high-density meeting blocks, and managing momentum to close the round efficiently.
- Optimize Investor Relations - Assist in creating systematic asks and reporting structures to extract maximum value from the existing cap table.
Core Principles
Bootstrapping as a Business Skill
Jason Fried: "The reason I think it's great for entrepreneurs to start bootstrapping is because they just have more practice making money, and they get better, and better, and better at the fundamental skill you need to have ultimately to run a successful business, which is to make money."
Mastering the ability to generate profit from day one builds fundamental business muscles that external capital can often mask. Only seek investment if your business model truly requires massive upfront capital like hardware or factories.
Lead with Immediate Impact
Uri Levine: "Most people are missing the most important slide of their presentation is the first slide. This slide is going to be presented for the longest period of time. This is the place that you're going to put your strongest point. Now the second most important slide is the last one."
Investors form opinions quickly, so you must place your most impressive data or insight on the very first slide. This captures attention immediately and sets the tone for the rest of the presentation.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fundraising is a skill published in the GitHub repository RefoundAI/lenny-skills (1,318 stars, last pushed 1mo ago), licensed MIT. It adds 35 tokens to every session and 1,641 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
