How startup turbocharging VCs began with a blog

Signal AI’s decision augmentation solution uses the world’s news, broadcast, blog and regulatory data to understand a decision maker’s context and extract knowledge from these diverse sources. 

It then delivers relevant knowledge through a SaaS interface, real-time alerts, interactive dashboards and a suite of APIs to help decision makers across a range of industries make informed and confident decisions. 

Signal AI’s insights are currently delivered to over 40% of the Fortune 500 through its strategic partnership with Deloitte.


“Signal AI is a stand-out category-defining business” said Tony Zappalà, partner at Highland Europe. 

“We are excited to be involved with the next chapter of the company’s innovative growth. 

“David and the leadership team have a clear vision for the decision augmentation category they are helping to define and as Gartner’s research has shown, the opportunity is huge.”
