Skills for startup founders by lool ventures.
A Claude Cowork plugin that gives founders four AI-powered coaching agents: market sizing, pitch deck review, financial model review, and IC simulation. Each agent follows a structured, script-backed workflow to produce analysis that holds up under investor scrutiny.
Skills
Market Sizing Agent
Builds credible TAM/SAM/SOM analysis — the kind that earns investor trust rather than raising eyebrows.
What it does:
- Calculates TAM/SAM/SOM using top-down, bottom-up, or both approaches
- Validates market claims against external sources (analyst reports, government data, industry stats)
- Stress-tests assumptions with sensitivity analysis and confidence-based range widening
- Runs a 22-item self-check against common market sizing pitfalls
- Assembles a final report with cross-artifact consistency validation
What to provide: A pitch deck, financial model, market data, or just describe the business (product, target customer, geography, pricing). The agent will research external sources to validate and build the estimate.
What you get back: A structured report with TAM/SAM/SOM figures (top-down and/or bottom-up), sensitivity ranges showing best/worst case, a scored self-check against common pitfalls, and coaching commentary on what will hold up in diligence.
Example prompts:
- "Here's the deck for Acme Corp -- can you validate their market sizing?"
- "We're looking at a fintech startup in the payments space targeting SMBs in Europe. What's the market look like?"
- "What happens to the market sizing if the customer count is 30% lower than estimated?"

Deck Review Agent
Reviews pitch decks against 2026 investor best practices, calibrated by stage (pre-seed, seed, Series A).
What it does:
- Scores 35 criteria across 7 categories (pass/fail/warn/not_applicable)
- Detects fundraising stage and applies stage-specific expectations
- Reviews each slide from the investor's perspective with specific, actionable feedback
- Grounds every recommendation in a named best-practice principle
- Assembles a scored report with overall deck readiness assessment
What to provide: A pitch deck in any format — PDF, PowerPoint, markdown, or text descriptions of your slides.
What you get back: A slide-by-slide review from the investor's perspective, a scored checklist (35 criteria across 7 categories), an overall readiness rating (strong/solid/needs work/major revision), and coaching on the highest-leverage changes to make before sending.
Example prompts:
- "Here's our seed deck -- can you review it?"
- "Is this deck ready to send to investors? We're raising a pre-seed round."
- "I have 10 slides: Slide 1 is our company intro with the tagline 'AI-powered compliance for fintechs'..."

IC Simulation Agent
Simulates a realistic VC Investment Committee discussion with three partner archetypes debating a startup's merits, concerns, and deal terms -- scored across 28 dimensions.
What it does:
- Simulates three distinct partner perspectives: The Visionary (markets/timing), The Operator (execution/GTM), The Analyst (unit economics/financials)
- Runs partner assessments independently via sub-agents for genuine diversity of perspective
- Scores 28 dimensions across 7 categories (team, market, product, business model, financials, risk, fund fit)
- Checks portfolio conflicts against the fund's existing investments
- Supports fund-specific mode with WebSearch-backed fund research
- Imports prior market-sizing and deck-review artifacts for grounded analysis
