Kumulos was a comprehensive mobile app engagement platform designed to help businesses acquire, engage, retain, and convert app users. It offered a suite of tools including personalized push notifications, in-app messaging, app store optimization (ASO), crash reporting, and analytics. The platform empowered developers and marketers to understand user behavior, automate and personalize communication, and improve app performance, ultimately aiming to drive user loyalty and revenue. In February 2022, Kumulos was acquired by Optimove, a leading CRM Marketing Hub, and its technology and team have been integrated into Optimove's offerings to enhance mobile marketing capabilities.
Served as the primary hub for Kumulos's operations, including product development, engineering, core sales, marketing, and customer support leadership before its acquisition by Optimove.
Located within Unicorn Co-working, indicating a modern, collaborative workspace rather than a standalone corporate building. This often fosters agility and networking.
As a tech scale-up, Kumulos likely fostered an innovative, agile, and customer-focused work culture. Being in a co-working space would also encourage collaboration and a dynamic environment. Post-acquisition, culture would align with Optimove's.
The Dundee HQ was significant as the birthplace and main operational center for Kumulos, driving its product innovation and initial global outreach. It represented a success story within the Scottish tech ecosystem.
Prior to its acquisition, Kumulos served a global client base from its UK headquarters and US office, with its platform supporting apps worldwide. Post-acquisition, Kumulos's technology and capabilities are integrated into Optimove's much larger global presence, which includes offices in Tel Aviv, New York, London, and other international locations, supporting clients in numerous countries with comprehensive CRM marketing solutions.

Key Kumulos leadership and personnel transitioned into roles within Optimove or departed. Therefore, executive new hires/exits in the last 12 months would be attributed to Optimove, not Kumulos as a standalone company.
