Free Startup Funding Simulator to Understand Modern Fundraising

This Startup Funding Simulator is hosted on You can visit the website and create a simulation right away. There is no need for an account or any type of sign-up. The tool has dark and light modes that you can toggle at your convenience. it keeps your simulation progress locally saved in the browser.

The startup funding simulation starts from the top where you can set the number of founders along with their equity. With a simple click of a button, you can add or remove founders and define their equity in the startup.

Funding Rounds

At the time of my testing, this tool covers the following rounds:

  • Safe (Post-money)
  • Priced round / Equity financing
  • Reserve/give options to employees
  • Exit (sell the startup)

Safe – Valuation Cap and Discount

A Safe with a valuation cap and discount is early-stage funding. It offers investors protection with a maximum valuation (cap) and rewards with a discounted price per share in the next equity round. You can add one or multiple series of funding in the simulation where you get to set the raised amount, valuation cap, and discount. Alongside each round, the tool gives an equity breakdown among founders. In my simulation, I added 2 safe rounds to understand how the effective valuation is calculated.

Priced Rounds

Price rounds are where startups sell equity to investors to raise capital. The tool lets you add any number of price rounds into the simulation. You can set the amount, valuation, and options for each round, You can also allow or disallow the pro-rata rights to investors. The tool instantly calculates the total equity sold with a breakdown among investors, safes conversion, and options pool increase. For a price round, the tool shows an equity breakdown among founders, investors, and options. I tried several priced rounds to verify the equity distribution along with the scope of pro-rata rights.


Reserve options are a pool of shares set aside for future equity grants to employees or advisors. On the other hand, Grant options are specific equity grants given to employees with the right to purchase shares at a set price. The option round lets you simulate the reserve options and grant options. Again, the tool shows an equity breakdown among founders, investors, and options.


Exit is where you want to sell the startup and walk away. This step lets you set a selling price for the startup and sell it at that price. After that, the tool shows the amount of equity you kept in the company after the sale. It also calculates how much money (before taxes) you will get after all investors get paid.

Assumptions and Limitations of this simulator

  • Only post-money safes and priced rounds
  • No down rounds
  • No pro-rata caps
  • Safes’ pro-ratas disappear after the first priced round
  • The remaining available options get redistributed evenly at the exit
