A term sheet contains many terms and conditions that affect your rights and obligations as a founder, as well as the economics and governance of your startup. It is important to evaluate key terms and trade-offs, such as pre-money and post-money valuation, liquidation preference, board composition and voting rights, and anti-dilution. Pre-money valuation is the value of your startup before the investment, while post-money valuation is the value after the investment. Liquidation preference is the amount of money that the investors get back before anyone else in the event of a sale, merger, or liquidation of your startup. Board composition and voting rights include the number of seats, allocation of seats between founders, investors, and independent directors, and quorum and majority requirements for board actions. Anti-dilution is a protection mechanism that adjusts the price per share of the investors in case of a down round. You should also pay attention to other clauses that may affect your startup, such as vesting, drag-along, dividends, redemption, conversion, and confidentiality. Maximizing pre-money valuation while minimizing dilution of existing shareholders is key in order to ensure a fair outcome for all parties involved.
