Your valuation must fit within our risk/reward expectations for the investment. Typically, we look for pre-money valuations of $250k upto $5 million. It takes unusual situations (e.g., a company with existing revenues, issued patents and demonstrated growth) to get us to consider a pre-money valuation higher than $5 million.
In determining valuation we take into account the effect of all commitments to issue shares, which is called the “fully-diluted” number of shares. More specifically, the fully-diluted number of shares includes all shares that you would issue if all unconditional and contingent commitments to issue shares were to be given effect (e.g., exercise of options and warrants, conversion of preferred shares, exchange of debt for equity, etc.). Moreover, we expect a reasonable number of shares to be already reserved (and counted as part of full-dilution) for filling out the key management slots and for other employee stock options.
The pre-money valuation, simply put, is the value you put on your company before getting the capital you seek. To compute: multiply the fully-diluted shares immediately prior to the proposed financing (e.g., 2 million fully-diluted shares) by the price/share of the proposed financing (e.g., $1/share) to yield the pre-money valuation ($2 million, in this example). If you add the proposed financing amount (e.g., $500K) to the pre-money valuation you get the post-money valuation ($2.5 million in this example).
Pre-money valuation based on percent of company
Some entrepreneurs are more used to thinking in terms of offering some percent (e.g., 20%) of their company for some amount (e.g., $500K) of financing. Numerically, divide the proposed financing ($500K) by the offered percentage (20%) to get the post-money valuation ($2.5 million), and subtract the money ($500K) from the post-money ($2.5 million) to get the pre-money valuation ($2 million). Note that these are just two different ways to compute the valuation; and hence, as expected, yield the identical results.
Investment value vs. company valuation
It is important to keep in mind that early stage investors will likely have their equity interest in your company diluted (made smaller) by later investors. For example, if angel group members invest $500,000 at a pre-money valuation of $1 million (and thus end up owning 33% of the company), and then a venture capital firm invests $5 million the following year at $5 million pre-money valuation, the original angel group investors will now own only half as much of the company, even though the company value has increased more than three-fold. As a result, because of the early stage at which we invest, you should know that angel group members generally receive 25-50% of the company’s fully diluted equity in exchange for their investment.
