Mautic is a marketing automation software platform and the most important open source alternative to systems such as Hubspot, Pardot and Marketo. With a state-of-the-art interface, it offers all the features needed to automate processes in inbound marketing, including workflows, landing pages, e-mail / SMS / social marketing and behavior-based targeting of anonymous website visitors ("smart" or "predictive" content).
The Mautic project is led by Mautic Inc., founded in 2014, the co-founder of which is Mautic mastermind David Hurley. Mautic as well as other providers offer a SaaS variant as a hosted service, but above all, Mautic can be operated independently.
Mautic has already found widespread use over a short period of time with over 200,000 applied organizations. Usage as well as the open source community continue to grow strongly, with particular emphasis in North and South America and Europe.
