Sept 11 (Reuters) - Klaviyo is seeking a fully-diluted valuation of up to $8.4 billion in its initial public offering (IPO) in the United States, the marketing firm said on Monday, as it becomes the latest company to tap a growing wave of stock market listings. However, the company's proposed valuation is a climb-down from the $9.15 billion pre-money valuation at which Klaviyo last raised capital in 2021, reflecting a broader gloom in the technology startup ecosystem. Founded in 2012, Klaviyo helps store and analyze data for e-commerce brands that enables them to send out personalized marketing emails and messages to potential customers. Klaviyo posted 51% growth in revenue to $164.6 million for the three months ended June 30. The company is expected to debut in September, a busy month for stock market listings that could serve as a litmus test for other companies looking to go public.
