MathStar, Inc. was an American fabless semiconductor company based in Hillsboro, Oregon.

Founded in 1999 by Douglas Pihl and Bob Johnson in Minneapolis, Minnesota. From 2001 to 2004 MathStar raised over $30 million in capital to design and manufacture their chips. MathStar's initial models were first shipping by 2003, however technical issues lead to design changes that delayed production to late 2005. In 2005, following an IPO, MathStar raised roughly $25M. Later the same year they moved their headquarters to Hillsboro, Oregon. In late 2006 MathStar re-introduced their first few production models. From late 2006 to 2008 MathStar continued hemorrhaging money (upward of -$20M per year) with very little revenue to show for. By late 2008 MathStar entered into a series of negotiations for a merger with potential companies including PureChoice, Tiberius, Sajan Inc., and a number of other undisclosed companies. On February 23, 2010, MathStar (which at the time was just a shell company with a single employee) and Sajan completed a reverse takeover. MathStar was subsequently renamed Sajan, Inc. which remained a publicly trading company.
