Mailchimp recently agreed to be acquired by Intuit for $12 billion. The company founded by Ben Chestnut and Dan Kurzius in 2001 hit possibly the highest sale amount ever of a privately bootstrapped company, and is an inspiration to all startups on building a company ground up. I found three interesting strategic decisions in Mailchimp’s journey. Mailchimp was one of the earliest providers to introduce micropayments of $5 a month in their early days. Freemium and micropayments have become a template for SaaS today. Secondly, they focused on small businesses, when most tech was geared towards the enterprise. Lastly, they pivoted the company away from just email into social media and marketing. Kudos to Ben and Dan on this fantastic journey. The $12 Billion valuation does indicate a massive potential in Email marketing! Did you know there are over 100,000 libraries in open source for email automation and marketing? You could look to build the next unicorn in email automation! kandi kit for Email Marketing Solutions showcases open source libraries across Email Marketing Automation, Core Email Platforms, Gathering and Processing Email Addresses, and engaging Email Templates.
