Intuit is in talks to acquire Mailchimp in a deal valued at more than $10 billion, Bloomberg reported on Wednesday, citing sources. Intuit is the creator of TurboTax and other accounting software, while privately held Mailchimp is a digital marketing service. No final decision has been on any deal and talks could fall through, or another buyer could emerge, the sources said. Neither company responded to requests for comments by Bloomberg. Intuit shares closed down 0.1% on Tuesday.
