2 Min Read (Reuters) -Infrastructure software startup Confluent Inc said on Wednesday it had sold shares in its U.S. initial public offering (IPO) above its target range to raise $828 million. Confluent priced 23 million shares at $36 per share. The company had previously priced its share between $29 and $33 apiece. The IPO values Confluent at $9 billion. There have been a flurry of major tech listings as a number of startups look to capitalize on the sky-high investor demand for new, high-growth tech stocks. The company counts venture capital firms Benchmark Capital Partners VIII LP, Sequoia Capital, and Index Ventures among its prominent backers. Benchmark, which owns about 15.3% of Confluent’s common stock, is the largest shareholder, according to a regulatory filing last week.
