IntraLinks Holdings, which provides secure online document management to over 4,300 customers worldwide, filed on Monday with the SEC to raise up to $150 million in an initial public offering. IntraLinks has filed to go public twice before: once in 2000 and again in 2005; both deals were withdrawn. The New York, NY-based company, which was founded in 1996, booked $45 million in Adjusted EBITDA on $141 million in sales last year. Morgan Stanley, Deutsche Bank Securities and Credit Suisse are the lead underwriters on the deal, for which pricing terms and timing were not disclosed.
