Option123, LLC ("Option123"), a limited liability company formed in state of Delaware, is a leading provider of stock option administration, valuation and reporting software in the United States. By providing user-friendly software package to over 300 companies worldwide, including Fortune 500, large CPA firms, as well as a host of small to medium-sized businesses, Option123 has become the leading supplier of stock option software. It was founded in 1999 when we had an unpleasant experience in valuing stock options, and we decided there had to be a better way to handle valuation of stock options by using "Binomial Option Pricing Model" (using either "constant inputs" over the term or "variable inputs at each node") and the Nobel Prize winning "Black-Scholes Option Pricing Model".

Our mission is to provide the-state-of-the-art software solutions to companies offering stock benefit programs to their employees. By providing expertise, simplicity, and cost savings to our clients, we are determined to help our clients manage their equity plans, prepare accurate valuations, as well as present satisfactory and consistent reports to SEC.

After all, Option123 is the only software that allows individuals who are not experts in valuation to value employee stock options using robust lattice model.
