About Leadsius
The Marketing role has evolved drastically, but the tools for empowering Marketers to perform have not kept up with the needs. Marketing Automation tools are often complex, expensive, and involves a steep learning curve. At Leadsius we wanted to find a better way, to think differently. We don't believe in one-size-fits-all; we believe in passion for marketing and performance. Dedicated to help Marketers turn their Marketing into a revenue driver, we designed a tool to optimize Marketing effectiveness. We made it easy to get started with and let Marketers decide when to add more functionality to fit their needs. At Leadsius, we aim to pave the way for a new era for Marketing, by creating a tool that revolutionizes the way Marketing is performed.
