What Magma Math does

Magma Math (legally Radish Education, Inc.) is a private K-12 instructional math platform founded in Sweden in 2015 and now headquartered in New York, with operating entities in Stockholm (Radish AB) and Berlin (Radish Education GmbH). The company serves K-12 schools, districts, and educators through an AI-powered platform that enables students to show their mathematical thinking digitally and gives teachers real-time visibility into student reasoning processes via features including Student Work Replay, tiered Assignment Creation, automated Heatmaps for identifying struggling learners, and a Teacher Dashboard for district-wide progress tracking. The platform combines multimodal AI (processing handwritten and typed solutions) with research-based pedagogy aligned to the Building Thinking Classrooms framework and NCTM math practices, and supports accessibility via 120+ language translation, text-to-speech, and color-vision deficiency accommodations.

The product is sold on an undisclosed subscription basis (annual billing cadence) to school districts under enterprise field sales, with self-serve free account creation available and complementary distribution through Apple App Store, Google Play, and Microsoft Store. Magma Math has accumulated an extensive compliance and evidence portfolio — SOC 2 Type II, COPPA, FERPA, NYCDPA, EdSafe AI membership, ISTE Seal (2025-2027), and ESSA Level II certification (December 2025, validated by a 1,686-student study in an Ohio district) — that is largely decisive in K-12 procurement. The company has raised $50 million in equity to date, led by Five Elms Capital across a $40M Series A (November 2024) and $10M follow-on (October 2025), supplemented by a near-$700,000 grant from the Bill & Melinda Gates Foundation to build AI-powered teacher tools for underserved K-9 communities. Named reference customers include Sewanhaka Central High School District, Bethlehem Central, Wyckoff, Alabaster City Schools, and Yuma School District One.

Emerging players

• Edia: Edia is an AI-native K-12 math platform that uses AI to provide real-time feedback on student work. It competes with Magma Math in the emerging AI-math-for-schools category, particularly on differentiated, teacher-friendly math practice.
• Khan Academy: Khan Academy is a widely used free K-12 learning platform with significant math content and a growing teacher tools offering (Khanmigo). It overlaps with Magma Math on math instruction but is differentiated by its free, consumer-driven model, making it a partial substitute in budget-constrained districts.
• Mathspace: Mathspace is an adaptive math learning platform serving K-12 and higher education with step-by-step reasoning and AI feedback. It is an emerging competitor with overlapping use cases (showing work, AI-driven insights) but smaller scale and geographic footprint than Magma Math.

Direct peers

• ST Math (MIND Research): ST Math is a visual, game-based K-12 math instructional platform widely adopted in US districts. It overlaps directly with Magma Math in target customer (K-12 districts), subject (math), and use case (instructional software with teacher insights).
• Zearn: Zearn is a nonprofit-backed K-8 math learning platform widely used in US school districts. It competes head-to-head with Magma Math for district math curriculum and differentiated practice dollars, with a similar horizontal, classroom-based deployment model.
• Carnegie Learning: Carnegie Learning provides AI-driven K-12 math instructional software (MATHia) and tutoring services. It targets the same district math buyers as Magma Math with adaptive, standards-aligned math instruction, and represents a direct competitor for mid-market and enterprise district contracts.
• DreamBox Learning: DreamBox is an adaptive K-12 math platform that uses AI to personalize instruction. It is the closest direct competitor to Magma Math, serving the same district buyers with similar subscription-based, standards-aligned math software.

Broad incumbents

• Imagine Learning: Imagine Learning is a large K-12 EdTech incumbent offering math, literacy, and supplemental instruction. It competes with Magma Math in math instruction and is frequently bundled into multi-subject district procurements that can crowd out standalone platforms like Magma.
• IXL Learning: IXL is a large, established K-12 platform covering math, ELA, science, and social studies with deep district penetration. It is a broad incumbent that competes with Magma Math on math practice and skills but offers a much wider subject portfolio that can displace single-subject tools in district-wide contracts.

Others

• Newsela: Newsela is a K-12 instructional content platform primarily focused on literacy and cross-curricular content. It is not a direct math competitor but is a frequent co-vendor in district EdTech stacks, making it a relevant adjacent peer for benchmarking district go-to-market and content licensing motion.
