What industry-leaders say

George Deglin
CEO OneSignal

"Our ContextSDK partnership enables us to have a compelling AI narrative when speaking with prospects. Many other approaches to AI in our market have limited value. But ContextSDK can actually drive meaningful impact on engagement and conversion rates."

Aymeric Roffé
CEO BeReal

"With Context Insights we address a crucial blindspot in our Analytics Setup: the real-world context of a user when using our app. For the first time we will have a 360 degree contextualized picture how our customers are using our app"

Eric Seufert
Independent Analyst & Investor

"ContextSDK and its assessment of real-world context adds a unique new data vector to close the loop on conversion to achieve 360 degree contextualization. This will advance the mental models of measurement across the mobile ecosystem."

Florian Gschwandtner
Former Founder & CEO of Runtastic

"For me this is a no-Brainer! As a product owner I'd love to learn more about the real-world contexts in which my users are using my apps - this will allow me to design better customer journeys."

Peter Steinberger
Former Founder PSPDFKit

"ContextSDK creates value for mobile app product owners from day 1, shedding light on insights such as the impact of real-world context on session length."
