In 2009, Elliot Turner launched AlchemyAPI to process the written word, with all of its quirks and nuances, and got immediate traction. That first month, the company's eponymous language-analysis API processed 500,000 transactions. Today it's processing three billion transactions a month, or about 1,200 a second. “That's a growth rate of 6,000 times over three years,” touts Turner. “Context is super-important,” he adds. “'I'm dying' is a lot different than 'I'm dying to buy the new iPhone.'” “As we move into new markets, we're going to be making some new hires," Turner says. "We knocked down some walls and added 2,000 square feet to our office.” “We're providing the ability to translate human language in the form of web pages and documents into actionable data,” Turner says. Clients include Walmart, PR Newswire and numerous publishers and advertising networks. “This allows a news organization to detect what a person likes to read about,” says Turner of publishers and advertisers.
