The file

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  1. Very specific:

    Every startup repository should maintain a live metrics tracker in docs/startup-metrics.md:

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Software Startup Full Lifecycle & Growth Skill

This skill guides founders and engineering teams through building, launching, operating, monetizing, and scaling a high-growth SaaS / AI startup directly from the repository.


1. The Startup Growth Engine Matrix

[Phase 1: 0 to 1 — Problem-Market Fit & MVP]
  ↳ Grill-Me Ideation → Scope Minimization (3 Tracer Slices) → Landing Page Waitlist + Stripe Pre-orders
          ↓
[Phase 2: 1 to 10 — Product-Market Fit (PMF) & Telemetry]
  ↳ PostHog / Mixpanel Event Tracking → North Star Metric → Sean Ellis PMF Survey (>40% "Very Disappointed")
          ↓
[Phase 3: 10 to 100 — SaaS Monetization & Growth Loops]
  ↳ Stripe Billing / Polar / LemonSqueezy (Subscriptions, Metered Tokens, Team Seats) → Referral & SEO Loops
          ↓
[Phase 4: Scale — Unit Economics & Operational Governance]
  ↳ Churn & Retention Cohorts → LTV / CAC Ratio (>3:1) → SOC2 / Compliance → Self-Serve Enterprise Upgrades

2. Startup Engineering Standards

A. SaaS Monetization & Pricing Architecture

  • Pricing Models:
    • Tiered Subscriptions: Free / Starter / Pro / Enterprise.
    • Usage-Based (Metered): Bill per API call, token consumed, or storage GB.
    • Per-Seat: Scaled pricing per team member.
  • Billing Provider Integration: Stripe Elements, Customer Portal, Webhook Handlers (invoice.payment_succeeded, customer.subscription.deleted), and dunning email triggers.

B. Founder Telemetry & Analytics Instrumentation

  • North Star Metric: Track the one event indicating primary user value (e.g. query_executed, report_exported, claim_processed).
  • Funnel Drop-Off Tracking:
    • User Visited Landing Page → Signed Up → Completed Onboarding → Invited Teammate → Paid.
  • Feature Flags & A/B Testing: PostHog / LaunchDarkly flags to test pricing experiments and checkout flows safely.

C. Automated Customer Feedback & Churn Mitigation

  • NPS & In-App Surveys: Automated survey trigger after 7 days of active usage.
  • Cancellation Flow: Capture exit reason (Too expensive, missing feature, buggy, switched to competitor) and trigger discount/rescue offer.

3. Investor & Unit Economics Dashboard

Every startup repository should maintain a live metrics tracker in docs/startup-metrics.md:

MetricTarget / BenchmarkFormula / Meaning
MRR / ARRGrowing 15-20% MoMMonthly / Annual Recurring Revenue

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
