  Duck Creek Technologies Inc. on Wednesday raised the expected pricing range of its initial public offering of 15 million shares to $23 to $25 apiece from a prior range of $19 to $21 each. 


  At the $24 midpoint of the new range, the Boston provider of software and services to the insurance industry said it expects net proceeds of about $333.7 million, or roughly $384.7 million if the underwriters exercise an option to buy an additional 2.25 million shares. 


  In a filing with the Securities and Exchange Commission, Duck Creek said it would have about 130.6 million shares outstanding after the IPO, assuming exercise of the overallotment option, for a valuation of about $3.13 billion at the $24-a-share midpoint. 


  Duck Creek said funds advised by private-equity firm Apax Partners L.P. will own a roughly 33.2% stake, assuming  exercise of the greenshoe, while Accenture PLC will own about 22.1%. 


  Duck Creek said it has applied to list its shares on the Nasdaq Global Market under the symbol DCT.
