GG4L Acquires Stackup

GG4L’s School Passport® iPaaS will Bundle Stackup’s Patented Learning Engagement Measurement and Reporting Technology

Alameda, CA – June 22, 2021 – Today, Global Grid for Learning (GG4L) announced the acquisition of Stackup, an EdTech startup with a focus on learning outcomes in K-12 education. Stackup’s AI-based data analytics technology will be securely integrated and deployed through GG4L’s School Passport, an Integration as a Service (iPaaS) Platform, widely used by more than 20,000 schools serving over 10 million students.  

Stackup is easily installable on all student devices, including Chromebooks and laptops, to capture and report real-time anonymized learner engagement data. Stackup’s patented technology measures when students are actually engaged with high accuracy. Teachers can assign and monitor reading by reading level, subject area, and website. Stackup also calculates the reading level and subject area as students read and learn across the Web. While browsing the Web, Stackup knows when a student is engaged in any online content.

Stackup enriches School Passport’s platform capabilities, for both schools and EdTech vendors, enabling schools to manage, roster, navigate, and measure digital learning across all grade levels. 

“We began our Stackup journey to unlock and reward learning across the digital space. As we turn the page, I don’t believe anyone can help us accelerate our vision better than GG4L. We are pleased and proud to be joining the GG4L family.” said Nick Garvin, Founder of Stackup, recognized as Forbes 30 under 30.

“Stackup enables schools and colleges to capture evidential 24×7 data to precisely measure and monitor student online attendance time and learning engagement activities across all digital Apps and resources, including any website on the Web.” said Robert Iskander, GG4L Founder and CEO. “Stackup will be the cornerstone for our Future-Proof Skills initiative enabling the stacking of learners’ micro credentials and badges to pre-qualify them for specific career pathways.”

School Passport, including the pre-integrated Stackup extension, is free to all GG4L member schools globally.  The Stackup teacher and admin reporting tool is available now in GG4L Compass under an optional annual license agreement. For a free 30-day trial, reach out to
