What LetterSchool does
LetterSchool is an Amsterdam-based edtech company (Letterschool Enabling Learning B.V., founded 2016) that develops mobile-first educational applications teaching children ages 3–8 handwriting, letter recognition, and early literacy/numeracy. The company's flagship product, 'LetterSchool – Learn to Write!', teaches uppercase and lowercase letters, numbers 1–10, and cursive through a three-step pedagogical method (learning starting points, tracing, then writing without hints) with adaptive visual cues that fade as proficiency improves. A companion 'LetterSchool – Spelling Words!' app extends the offering into 150+ spelling words, and a dedicated 'LetterSchool for Schools' product provides multi-language, multi-player classroom versions used at over 5,000 schools worldwide.
The platform is built as iOS and Android tablet applications distributed through the Apple App Store and Google Play Store, supporting 11–12 languages aligned to local curricula and three major US handwriting fonts (Handwriting Without Tears, D'Nealian, and Zaner-Bloser). Proprietary technical components include the adaptive feedback engine, multi-player progress tracking for up to three users per device, and COPPA/GDPR/FERPA-compliant data handling. Third-party efficacy validation comes from a University of Texas at Arlington study documenting improved manual dexterity versus traditional pencil-and-paper methods, and the products have earned multiple industry awards (NAPPA, KAPi, Tabby Awards, Children's Technology Review Editor's Choice).
The business operates a hybrid go-to-market: a product-led consumer model with a 7-day free trial converting into auto-renewing monthly, quarterly, or annual subscriptions via app stores, paired with a B2B institutional channel ('LetterSchool for Schools') that sells multi-seat licenses and school packages directly through the company website. The company reports over 500,000 children learning with the app and more than 2,000,000 confirmed installations, with primary user markets in the USA, Brazil, and the Benelux region. Operations remain lean (1–10 employees, no external institutional funding identified), with founder and Managing Director Sjoerd Huitema leading a bootstrapped, founder-controlled business.
