What DeltaMath does
DeltaMath, operated by DeltaMath Solutions Inc. and headquartered in Larchmont, New York, is an online math practice and learning platform serving K-12 teachers, students, schools, and districts. Founded in 2009 by Zach Korzyk, who remains CEO, the platform is built on MathQuill technology and offers a curated library of more than 2,500 math skills spanning standard, guided, graphing, timed, discovery, geometric proof, and geometric construction problem types from lower elementary through 12th grade. Problems are randomized and deliver instant, age-appropriate feedback with optional help videos, and the platform conforms to WCAG 2.2 accessibility standards including screen reader support, Trace Mode, Braille printouts, and high-contrast mode.
The product surface is organized into three tiers: a free teacher account, the PLUS/INTEGRAL premium subscriptions (sold per school year on a quote basis, with features such as custom problem creation, test creation, Print to PDF with answer keys, and a custom graph creator), and DeltaMath for Home, a consumer subscription with a 7-day free trial and monthly or annual billing targeting parents and independent learners. DeltaMath generates revenue primarily through annual school-year subscriptions that do not auto-renew, meaning revenue must be re-earned each year, with a secondary, growing consumer subscription stream. Distribution is sales-led, direct to schools and teachers, supplemented by integrations with Google Classroom, Canvas, Schoology, Infinite Campus, Clever, and ClassLink for roster sync, single sign-on, and grade passback.
The company operates with a very lean team of 1-10 employees, has no disclosed outside funding, and reports "millions of users" and "billions of problems solved" across its platform. It maintains FERPA, COPPA, SOPPA, and NY 2-D student data compliance. Strategic emphasis has been on broadening curriculum coverage (2024 expansion into 4th and 5th grade), launching a consumer channel, and deepening LMS integration footprint rather than pursuing venture-scale hyper-growth.

DeltaMath competitors and assessment
Company assessmentDirect peers
- IXL Learning: Subscription-based K-12 math (and other subjects) practice platform with randomized problems, instant feedback, and analytics. Most direct competitor to DeltaMath in the school-license math practice category.
- ASSISTments: Math homework and practice platform originally built by teachers, offering instant feedback on student work to teachers. Closest peer in terms of teacher-built origin, math-only focus, and feedback-driven practice.
- Khan Academy: Free K-12 math practice and instructional platform with mastery-based learning and teacher dashboards. Competes with DeltaMath on K-12 math practice, particularly at the free and budget-constrained end of the market.
- DreamBox Learning: Adaptive K-8 math learning platform sold to schools and districts. Direct competitor in school-licensed adaptive math practice, with deeper K-5 emphasis than DeltaMath's historical 6-12 focus.
- Desmos: Math tools company providing graphing calculators, classroom activities, and practice. Overlaps with DeltaMath in interactive math tools, graphing, and teacher-built classroom resources, particularly in secondary grades.
Broad incumbents
- Carnegie Learning: Long-established math education software company (MATHia, MATHbook) serving districts with adaptive tutoring and curriculum. Broader incumbent competing for the same district math budgets as DeltaMath.
- Imagine Learning: K-12 supplemental curriculum and software provider with math, reading, and language offerings. Competes with DeltaMath for district math budgets as a multi-subject vendor.
- Quizlet: Broad study-practice platform with teacher and student tiers, including math study modes. Adjacent competitor for student practice time and teacher attention in K-12.
Regional players
- Mathletics: K-12 math practice platform with strong international (especially UK/Australia/Asia-Pacific) footprint. Comparable math-only subscription model but largely non-overlapping geographic footprint with US-centric DeltaMath.
Emerging players
- Albert (Albert.io): K-12 practice and assessment platform with strong math content, sold to schools and teachers. Emerging competitor overlapping with DeltaMath's premium teacher and school/district tiers.
