What Teachley does
Teachley is a New York-based K-5 math learning company founded in 2011 by three women with PhDs in Cognition and Learning from Columbia University. The company sells a research-backed, game-based math intervention platform that combines adaptive learning games (Addimals, Subtractimals, Mt. Multiplis, Market Bay, Fractions Boost, Fractionators), animated videos, eBooks, formative assessment dashboards, and structured lesson plans covering operations, place value, fractions, and decimals. Products are aligned to Common Core, TEKS, and state standards, integrate with Clever, ClassLink, and Google SSO, and run on Chromebook, iPad, and web. The flagship platform Teachley Connect provides real-time formative assessment and data dashboards for teachers, districts, and families.
Teachley generates revenue primarily through annual subscription licenses sold to classrooms ($360/year), schools ($342/class for 5+ classes), and districts with multi-site custom pricing, plus a managed-service Tutoring with Teachley Math program and a $4.99/month family subscription. Go-to-market combines product-led growth (free educator accounts, $30 Quickstart trial, app store presence) with sales-assisted enterprise motion (Calendly demos, quote requests) and research-driven credibility through partnerships with Johns Hopkins CRRE, WestEd, Teachers College, and Success for All Foundation. The company holds FERPA, COPPA, NIST 800-171, Student Privacy Pledge, and Digital Promise Research-Based Design certifications and has received multiple SBIR grants from the U.S. Department of Education IES, NSF, and NIH totaling roughly $900,000 in disclosed amounts plus NewSchools Venture Fund equity investment in 2017.
The business is founder-controlled, privately held, and operates with a lean 1-10 person team from its New York headquarters at 25 Broadway. Strategic expansion has prioritized bilingual (English/Spanish) Math Corps content via HITN, integration into the ASSISTments platform, and a recent move into managed high-dosage tutoring services, positioning Teachley for incremental growth in both institutional and family segments.

Teachley competitors and assessment
Company assessmentDirect peers
- Prodigy Education: Game-based adaptive math platform for grades 1-8 with strong classroom adoption and a freemium consumer model via the Prodigy Math Game app. Competes on engagement and adaptive difficulty for K-5.
- DreamBox Learning: Adaptive K-8 math platform owned by Discovery Education, sold via district subscriptions. Competes directly with Teachley's adaptive intervention product in U.S. elementary schools.
- Zearn: Free K-5 math curriculum and intervention platform widely adopted in districts. Overlaps with Teachley Math Intervention and Fractions Boost Curriculum as a free or low-cost alternative that competes for district math intervention dollars.
- ASSISTments Foundation: Math problem-solving and formative assessment platform developed at Worcester Polytechnic Institute. Now an integration partner for Teachley Problem Solving, and competes in the math problem-solving formative assessment space.
- Happy Numbers: K-5 visual, manipulative-based math platform with district pricing and SSO integrations. Closely comparable to Teachley on format (visual, manipulatives, cross-platform, district deployment) and grade band.
- MIND Research Institute (ST Math): ST Math is a game-based visual math intervention platform for K-8 students with strong efficacy claims. It is the most direct comparison to Teachley's adaptive, visual, game-based approach to building math conceptual understanding.
Broad incumbents
- Curriculum Associates (i-Ready): i-Ready Diagnostic & Instruction is a dominant K-8 math assessment and intervention solution sold at district scale. Sets the bar for efficacy evidence in math intervention purchasing and is used as the outcome measure in Teachley's own RCTs.
- IXL Learning: Broadly adopted K-12 math and ELA practice and assessment platform sold via district and family subscriptions. Competes in K-5 math practice/intervention, though its approach is more procedural and broader than Teachley's strategy-focused games.
- Imagine Learning (Imagine Math): Major K-12 supplemental solutions provider including Imagine Math (formerly Imagine Learning's math intervention). Competes at district scale in math intervention where Teachley also plays.
- Khan Academy (Khan Kids, Khan World School): Free K-12 math video and practice platform with strong brand recognition and district partnerships. A free alternative in many categories, but increasingly bundling structured learning programs that overlap with Teachley's intervention use case.
