I2A led the round with participation from other major investors, including Pritzker Group Ventures, Baird Capital, EPIC Ventures, and Silicon Valley Bank.

Signal will use the proceeds to further accelerate and expand its technology platform and organization globally to take advantage of the strong and growing demand for addressable marketing solutions around the world.

'Today's consumers are hyper-connected and moving across devices and channels faster than ever before. Signal's platform was built from scratch for the realities of our always-on world, where brands and agencies need new approaches to help them connect with real people in more meaningful ways,' said Kapil Chaudhary, Managing Partner, I2A. 'It's exciting to see how rapid adoption of Signal's platform globally is driving impressive growth with both current and new customers.'

With a total of over $70 million in funding to date, Signal has evolved into one of the fastest growing software companies in the US. Underscoring its proven business model, the company has experienced high double-digit growth since inception. Signal has over 20,000 companies and brands actively using its platform in the US, APAC, EMEA, and South America, and across multiple verticals including retail, CPG, automotive, travel, entertainment and more. The company's impressive revenue trajectory made it the 3rd fastest growing software company in the latest Inc. 5000 rankings.

'Complexity and fragmentation across the digital marketing landscape has compounded since Signal was founded six years ago. Most marketing technology operates in silos which hampers brands' ability to connect their data to known users,' said Mike Sands, Signal CEO. 'Signal is the only solutions provider that delivers people-based marketing at scale through one open and agnostic platform that gives brands the foundation they need for reaching always addressable consumers in real time, anywhere they are.'
