Startup Cap Table & Equity Dilution Simulator

Take the guesswork out of fundraising. Visualize founder equity, calculate investor dilution, and map out your next funding round with our secure, 100% offline Cap Table Simulator.

Understanding equity distribution during a fundraising round is one of the most critical—and stressful—tasks for a startup founder. Traditional spreadsheets are prone to catastrophic formula errors, while cloud-based SaaS cap table management platforms (like Carta or Pulley) are incredibly expensive and require you to upload your highly sensitive, confidential company ownership structure to third-party servers.

The Startup Cap Table & Equity Dilution Simulator provides a blazing-fast, secure, and professional alternative. Designed specifically for early-stage founders and CFOs, this Single Page Application (SPA) runs entirely locally in your browser. You can instantly model complex funding rounds, see the immediate impact on your founder shares, and export pristine, investor-ready PDF reports—all without paying a monthly subscription or compromising data privacy.

🚀 Key Features for Startup Founders

• Instant Dilution Modeling: Easily input your target raise amount and pre-money valuation to see the immediate dilution impact. The system automatically calculates share prices, total post-money shares, and the exact ownership percentage retained by the founding team.
• Option Pool Expansion Calculator: Investors usually require the employee option pool to be expanded (typically 10-15%) before the round closes. Our simulator correctly calculates this “option pool shuffle,” showing exactly how much equity existing shareholders must give up to meet the investor’s demands.
• Interactive Visualizations: Forget boring rows of data. As you adjust the pre-money valuation slider, the built-in dynamic doughnut chart updates in real-time, providing a crystal-clear visual breakdown of who owns what post-round.
• 100% Offline & Private: Your capitalization table is your company’s most guarded secret. Because this tool relies on local browser processing, your ownership data, valuations, and investment targets never leave your device. Zero servers, zero data mining.
• Export Print-Ready PDFs: Need to show the cap table to your board, co-founders, or a lead investor? The tool features a highly optimized print view that strips away the UI controls and exports a professional, clean “Capitalization Table Analysis” PDF with one click.
• Unlimited Co-Founders: Add as many co-founders, early employees, or existing shareholders to the pre-round cap table as you need. The tool dynamically assigns distinct colors to each shareholder for easy tracking on the charts.

💡 How It Works (The Funding Math)

The simulator uses standard venture capital math to generate your new cap table:

1. Input Current Equity: Add your founders and their current share counts, along with any existing unissued option pool shares.
2. Set Round Parameters: Enter the amount of money you want to raise (e.g., $2,000,000) and the negotiated Pre-Money Valuation (e.g., $8,000,000). The system instantly calculates the Post-Money Valuation ($10M).
3. Define the Option Pool: Input the target percentage for the new employee option pool.
4. View the Results: The simulator calculates the new share price, the number of shares issued to the investors, the top-up shares needed for the option pool, and the final diluted percentages for everyone on the cap table.

👥 Who Needs This Tool?

• Startup Founders & CEOs: Model multiple “what-if” scenarios (e.g., raising $1M vs $2M) before walking into pitch meetings with VCs or Angel Investors.
• CFOs & Finance Directors: Quickly validate term sheet offers and explain the mathematical impact of a funding round to the executive team.
• Angel Investors & Advisors: Use the simulator alongside founders to transparently demonstrate how an investment offer will affect their ownership.
• Accelerators & Incubators: Provide cohorts with a simple, secure tool to understand equity math without forcing them to buy expensive SaaS subscriptions.
