As mentioned briefly above, there are multiple valuation methods to value a startup, and one not mentioned (but worth noting since this is arguably the most common startup valuation approach) is the Venture Capital Method that was developed in 1987 by Bill Sahlman.

If working with a venture capital firm, you should know how they calculate valuations. Venture capital firms use this valuation method to establish an understanding of the value of a startup using this basic framework. In addition to the venture capital method, a VC Term Sheet is used to define the specific conditions of venture capital investments between an early-stage startup company and the venture firm itself.
