Expert framework for assessing and achieving product-market fit.

  • Works in 3 steps: Find PMF in one segment (e.g.,… → Double down where you see natural pull → Expand to adjacent segments
  • Determining if product has PMF
  • SKILL.md covers Workspace Context, Operating Contract, Quick Reference and Part 1: What Is PMF?, plus 7 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Product Market Fit Analysis is an agent skill from manojbajaj95/claude-gtm-plugin. Expert framework for assessing and achieving product-market fit. Combines PMF measurement methodologies, Sean Ellis survey, retention analysis, segment-specific PMF, and post-PMF scaling strategy. Use when determining if product has PMF, measuring user engagement, running PMF surveys, or deciding whether to scale or keep iterating.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering Product strategy. The licence is MIT.

When your agent uses it

  • Determining if product has PMF
  • Measuring user engagement
  • Running PMF surveys
  • Deciding whether to scale

Example prompts

  • “/product-market-fit-analysis”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Find PMF in one segment (e.g., early-stage startups)
  2. Double down where you see natural pull
  3. Expand to adjacent segments

What it can do on your machine

Read from SKILL.md and the folder at commit 0830a46. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Product Market Fit Analysis loads about 2k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 972 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Product Market Fit Analysis

Workspace Context

Read bootstrap context before asking questions: strategy/brand.md for brand, audience, offer, channels, tools, constraints, and metrics; about/me.md for personal voice; content/ideas.md and content/calendar.md for content planning. Use legacy product-marketing context files only as fallback. Save generated drafts to content/<platform>/drafts/YYYY-MM-DD_short-topic-slug.md, and route durable learnings back to strategy/brand.md, about/me.md, or content/ideas.md.

Operating Contract

This skill is self-contained for its frontmatter scope: use its local instructions, references, scripts, and assets as the playbook; ask only for missing task-specific inputs; hand off to adjacent skills instead of expanding scope; and return an actionable artifact, decision, plan, draft, or diagnostic.

Comprehensive framework for assessing, achieving, and scaling product-market fit.

Part 1: What Is PMF?

Definition

Product-market fit is the condition where a product satisfies a strong market demand. It's not binary — it's a spectrum.

Key Insight

PMF is obvious when you have it.

Matt MacInnis: "Product market fit is something where you absolutely know it when you see it. Therefore if you don't absolutely know it, you don't have it."

Part 2: PMF Measurement Frameworks

Sean Ellis "Disappointment" Survey

The Question:

"How would you feel if you could no longer use this product?"

  • Very disappointed
  • Somewhat disappointed
  • Not disappointed

The Benchmark:

40% "very disappointed" = on the right track

Focus on the "very disappointed" segment as the core value indicator.

Retention Curves

Uri Levine's Definition:

"Product market fit has one metric. Retention. If you create value, they will come back. If they're not coming back, you're not creating value."

What to look for:

  • Curves that flatten over time (not decaying to zero)
  • "Smile curve" — engagement increases over time (strongest signal)

Key retention points:

  • Day 7 retention
  • Day 30 retention
  • Day 90 retention
Reference Customers

Christian Idiodi:

"The holy grail is really a reference customer - somebody who loves it enough to tell people about it."

MarketTarget References
B2B6-8 reference customers
B2C15-25 reference customers

Part 3: Leading Indicators

Signs of True PMF
IndicatorWhat It Means
"Very disappointed" > 40%Strong core value
Retention curve flatteningProduct creates ongoing value
Customer "pull"Market is pulling product
Outrage during outagesProduct is mission-critical
Customer driving next stepsIntent, not polite interest
Customer "Pull" Signals

Raaz Herzberg:

"We felt the questions change — 'How are you pricing this? When can we start a POV?' That's real intent."

True pull is characterized by:

  • Customers driving next steps
  • Questions about pricing/timelines
  • Urgency in communication
Outage Response Test

Jeff Weinstein:

"During those 20 minutes our customers weren't furious. That was the signal we did not have product market fit."

If your product goes down and nobody notices or complains, you haven't solved a mission-critical problem.


Part 4: Segment-Specific PMF

Key Insight

Karri Saarinen: "The way we think about it is, 'Do we have the fit in specific segments?' and how strong that fit is."

PMF exists in segments, not universally.

Finding Your Segment

Start narrow, then expand:

  1. Find PMF in one segment (e.g., early-stage startups)
  2. Double down where you see natural pull
  3. Expand to adjacent segments
Common Segments
  • Company size / stage
  • Industry vertical
  • Use case / workflow
  • Geography
  • Team size

Part 5: Distribution + PMF

Show full SKILL.md (407 more words)Show less
Critical Insight

Casey Winters: "If you have a product that retains well and you can't find more users for it, I don't think that's product market fit."

True PMF requires:

  1. ✅ Retaining product
  2. ✅ Scalable, built-in distribution

Without both, you don't have true PMF.


Part 6: Pre-PMF Navigation

What to Do Pre-PMF
  • Focus on retention, not acquisition
  • Talk to every customer personally
  • Iterate rapidly on product
  • Find the segment with strongest pull
  • Don't spend on paid acquisition
Warning Signs
  • Growth comes from "launch spikes" not organic
  • Users aren't coming back
  • No customers willing to be references
  • Market is pushing product, not pulling
  • You're guessing why users churn

Part 7: Post-PMF Scaling

Protecting PMF

Casey Winters: "Protecting what you've built is increasingly important once you build scale. You might fall out of product market fit in a year or five years if you're not continually making your product better."

Scaling Checklist
  • Retention curve has flattened (positive)
  • Have target reference customers
  • Clear segment with strongest fit
  • Built-in distribution mechanism
  • Team structure supports growth
PMF Can Be Lost

Markets shift, competitors improve, user expectations rise. Continuously monitor and protect PMF.


Part 8: Questions to Assess PMF

Diagnostic Questions
  1. If users couldn't use your product anymore, what percentage would be 'very disappointed'?
  2. What does your retention curve look like at day 7, 30, and 90?
  3. Do you have customers willing to be references and tell others about you?
  4. Is the market pulling the product from you, or are you pushing it on them?
  5. Are customers driving next steps or just being politely interested?
  6. What specific segment do you have the strongest fit in?

Part 9: Common Mistakes

What to Avoid
MistakeReality
Confusing launch spikes with PMFSustained organic growth matters
Ignoring retention dataIf they don't come back, no PMF
Scaling too earlyPaid growth before PMF burns cash
Conflating TAM with PMFLarge market ≠ fit within it
Listening to "somewhat disappointed"Focus on "very disappointed"
