What Weld North does

Weld North LLC is a private investment and operating company founded in 2010 by Jonathan Grayer, former Chairman and CEO of Kaplan, Inc., initially in partnership with KKR. Since 2018, its K-12 digital assets have been owned in partnership with Silver Lake, with Onex Partners V added as a co-investor in February 2021. The company operates Imagine Learning, described as the largest pure-play PreK-12 digital education company in the US, serving more than 15 million students across more than 7,500 school districts.

The core product is the Imagine Learning platform, a digital curriculum and education technology suite spanning literacy, language, mathematics, science, social-emotional learning, virtual robotics/coding, virtual tutoring, assessment, and intervention. Notable product brands within the portfolio include Edgenuity (online courseware in 20,000+ schools and 20 of the 25 largest US districts), LearnZillion (digital-first core curriculum with highest EdReports ratings), StudySync (ELA core curriculum), Twig Education (digital science curriculum co-developed with Imperial College London, Stanford, and BBC Studios), Robotify (virtual robotics/coding), Winsor Learning/Sonday System (Orton-Gillingham structured literacy used in approximately 4,000 districts), Purpose Prep (SEL), Assessment Technology Incorporated/Galileo (assessment), Glynlyon/Odysseyware/AOP (digital curriculum and homeschool), Think Through Math (adaptive math), GoPeer (virtual tutoring), and Imagine Ascend (special education launched in 2023).

Weld North generates revenue primarily through subscription-based digital curriculum licensing sold via direct enterprise sales to K-12 school districts on annual contracts with pricing that varies by district size, student count, and modules selected. The go-to-market is enterprise field sales to school and district administrators across the US, supplemented by acquisitions as a core growth mechanism. Weld North LLC itself is a small (1-10 employee) holding and operating company; scale is delivered through the Imagine Learning operating platform and its portfolio of acquired brands.

• Houghton Mifflin Harcourt (HMH): HMH is one of the largest US K-12 curriculum publishers with a fast-growing digital core curriculum platform serving K-12 districts. It directly competes with Imagine Learning's LearnZillion, Illustrative Mathematics, and StudySync products in state adoption cycles for core instructional materials.

Emerging players

• Khan Academy: Khan Academy is a free, non-profit K-12 digital learning platform widely used in US school districts as a low-cost supplement.

Broad incumbents

• Pearson (US K-12 business): Pearson operates a K-12 digital curriculum and assessment business in the US (Pearson Online Learning Services, formerly Connections Academy) as part of a broader global education and publishing portfolio. It is comparable as a peer in K-12 digital curriculum sales and assessment, though Pearson's overall focus has shifted away from US K-12.
