In an amended petition in a fraud and conspiracy lawsuit, an Austin businessman alleges Andrews Kurth engaged in legal malpractice when working on a financing agreement for a venture capital company to fund his startup.

On Feb. 8, Kyle Samani added Andrews Kurth as a defendant in the suit he filed Jan. 8 against S3 Ventures, a venture capital firm in Austin; related company S3 Ventures V; Brian Smith, managing director of S3 Ventures; and Charlie Plauche, vice president of S3.
