San Francisco-based Splunk, which develops enterprise indexing and analysis software, had a robust debut this morning on the Nasdaq As SPLK, after pricing at $17.00 per share last night. As of around 9am this morning, the company was trading around $32.00 per share, having risen as high as $34.75 in its first day of trading. Splunk had most recently raised its IPO estimates to between $11.00 and $13.00 per share, above an earlier initial range of $8.00 to $10.00 per share. The reception for Splunk is a huge win for its venture backers, August Capital, Sevin Rosen, JK&B Capital, and Ignition Partners, as well as its bankers, which included Morgan Stanley, Credit Suisse, J.P. Morgan, BofA Merrill Lynch, Pacific Crest Securities, UBS Investment Bank, and Cowen and Company. Splunk only just filed for an IPO on January 13th.
