What Winsor Learning does
Winsor Learning is a Minneapolis-based, privately held education company founded in 1997 that develops and distributes structured literacy curriculum built on the Orton-Gillingham methodology. Its flagship product line, the Sonday System — now marketed as the Imagine Sonday System following acquisition by Imagine Learning LLC — delivers multisensory, explicit phonics instruction across PreK through grade 12. The portfolio includes Let's Play Learn for PreK, Sonday System Essentials for K-5 whole-group phonics, WinVocab for digital vocabulary instruction, Sonday System 1 and 2 for Tier 2/3 intervention, Secondary 1 for older learners with reading gaps, and a Decodable Readers collection paired with Hi-Lo Readers and adapted literature.
The company's technology stack centers on a structured, systematic instructional framework designed to lower implementation burden relative to specialist-dependent Orton-Gillingham programs, supporting Tier 1 supplemental, Tier 2 small-group, and Tier 3 intensive intervention use cases. The company has built a content library of registered trademarks (Sonday System, Imagine Sonday System, Let's Play Learn, WinVocab) and supplements its software with professional learning, coaching, and Science of Reading training services. Winsor Learning operates with 11-50 employees and is headquartered in the United States; the website domain (winsorlearning.com) remains active while the product line is increasingly distributed through Imagine Learning's broader K-12 sales platform.
Winsor Learning's go-to-market is sales-led, targeting K-12 public and private schools and districts through direct enterprise outreach to administrators, reading specialists, and special education directors, complemented by a Shopify e-commerce storefront for direct purchases. Revenue is generated via annual subscription licenses for digital-first products and professional services for training and implementation support, with pricing provided on a quote basis. The primary customer segment is K-12 schools and districts across the United States, with named reference customers including Bryan County School District (GA), Dillon School District (SC), and East Orange School District (NJ).
