One of the most anticipated IPOs of a Southern California technology firm, LegalZoom is expected to hit the markets Friday, with pricing expected Thursday evening. The firm--which recently set its expected IPO pricing range of $10 to $12 per share--is one of two IPOs expected this week by technology companies. The company is aiming at the New York Stock Exchange, hoping to trade under the symbol LGZ. It's been a long road for the firm, which was founded in 1999, and has raised funding from such backers as Polaris Venture Partners, Institutional Venture Partners, and Kleiner Perkins Caufield & Byers.
