    Frequently Asked Questions

    How does equity dilution work in fundraising?

    When you raise funding, you sell a percentage of your company to investors. If you raise $2M at a $8M pre-money valuation, investors get 20% of the company ($2M / $10M post-money). Your ownership is diluted from 100% to 80% of the new total. Each funding round further dilutes existing shareholders proportionally.

    What is the difference between pre-money and post-money valuation?

    Pre-money valuation is your company's value before receiving investment. Post-money valuation is pre-money plus the investment amount. For example, a $10M pre-money + $2M investment = $12M post-money. Investor ownership is calculated as Investment / Post-money (not Pre-money).

    How should co-founders split equity?

    Equal splits are common but not always fair. Consider each founder's contribution in terms of: initial idea (5-15%), domain expertise (5-15%), time commitment (10-20%), capital contribution (5-25%), and network/relationships (5-10%). Our Equity Split Calculator helps you weigh these factors objectively.

    What is a standard vesting schedule?

    The industry standard is 4-year vesting with a 1-year cliff. This means no equity vests until the first anniversary (cliff), then 25% vests immediately, with the remaining 75% vesting monthly over the next 3 years. Some companies use 3-year or 5-year schedules, or monthly vesting from day one.

    How much runway should a startup have?

    Most VCs recommend 18-24 months of runway after each fundraise. This gives you 12-18 months to hit milestones before you need to start fundraising again (which takes 3-6 months). Running below 6 months runway puts you in a weak negotiating position.

    What is the Rule of 40 for SaaS companies?

    The Rule of 40 states that a SaaS company's growth rate plus profit margin should equal or exceed 40%. For example, 30% growth + 10% profit margin = 40%. High-growth companies can be unprofitable (50% growth + -10% margin = 40%), while mature companies need higher margins. It's a key metric for SaaS valuations.
