XtraMath

What XtraMath does

XtraMath is a 501(c)(3) nonprofit e-learning platform that helps K-8 students develop automaticity and quick recall of basic math facts in addition, subtraction, multiplication, and division. Founded in 2007 in Seattle by former Microsoft programmer David Jeschke and incorporated as a nonprofit in 2009, the company is led by CEO Roy King following the founder's passing in December 2024. The product is delivered primarily as a web application, supplemented by a mobile app that is temporarily unavailable, and uses an adaptive spaced-repetition methodology that presents math facts based on each student's current strengths and weaknesses against configurable fluency thresholds (1.5 to 12 seconds). All students must reach a mastery score of 100 to advance to the next operation.

The platform is structured around a freemium model. The core program is free for teachers and families, while Premium subscriptions unlock advanced reporting, custom program builders, printable resources, priority support, and rostering integrations. Premium is offered at three tiers: Family ($2/year), Teacher ($25/6 months or $50/year), and School ($250/6 months or $500/year). Revenue is supplemented by charitable donations processed via PayPal. The product is distributed through direct self-serve signup on xtramath.org, email-driven inside sales for school and district quotes, the Clever Library, ClassLink Roster Server (OneRoster), Google SSO, and federal funding channels including Title I and ESSA. In the 2023-2024 program year XtraMath reported 6.2M+ students and 575K+ teachers across 50+ countries.

The technology stack centers on the adaptive spaced-repetition engine hosted on AWS infrastructure in the United States, with AWS providers certified under EU-US and Swiss-US Privacy Shield. Bilingual content (English and Spanish), an American Sign Language video variant, and high-contrast visuals support accessibility, and the platform holds WCAG 2.1 AA, ESSA Tier IV, and Student Privacy Pledge compliance, alongside FERPA, COPPA, CCPA, and GDPR adherence. The team is small (1-10 employees) covering CEO, customer success, product marketing, customer service, engineering, UX/UI, legal and data privacy, sales and digital marketing, and data engineering. A new free product, Awakening, was launched in 2025 as a curriculum-aligned game-based learning platform available after daily math fluency sessions, with supporting research from WestEd and Vanderbilt University.
