By Tova Cohen TEL AVIV (Reuters) – ClickTale, whose software enables website owners to see how people behave on their sites, expects to maintain an annual sales growth rate of over 50 percent in the next few years as companies seek to improve their customers’ experience. “Sales have grown by thousands of percent over the last six years to tens of millions of dollars a year,” co-founder and Chief Executive Tal Schwartz told Reuters. “The growth rate is over 50 percent year over year.” The company raised $17 million in April from London-based Amadeus Capital Partners and Goldrock Capital in Israel, marking its first cash injection since attracting an initial $800,000 in seed money in 2007 and becoming profitable quickly. ClickTale is a complementary solution to Google’s Analytics or Adobe, said Schwartz.
