Education product studio

We build learning products that hold up — anywhere you sell them.

Interactive courseware, curriculum engineering, assessment, platform and growth — built by people who have shipped all of it. And the part most teams discover too late: the privacy, accessibility and procurement rules that decide whether you can sell in a market at all.

What we do

Six things, done properly.

01

Interactive courseware

Manipulables that teach by being used — graphers, balance scales, constructions, simulations. Built as components, not videos, so a learner changes a value and the mathematics responds.

  • Canvas & SVG interaction
  • Maths typesetting (KaTeX/MathJax)
  • 3D via Three.js
  • Authoring pipelines

02

Curriculum engineering

Mapping content to the curriculum a market actually teaches, then building the tooling that keeps hundreds of chapters consistent as they change.

  • NCERT / CBSE
  • Common Core & state standards
  • National curricula
  • Content build systems

03

Assessment & practice

Item banks, adaptive sequencing and per-learner progress. Including generated items that pass a second-model validation pass before a student ever sees them.

  • Item banking
  • Adaptive sequencing
  • Generation with validation
  • Reporting

04

Platform engineering

The unglamorous half: rostering, org and seat management, teacher dashboards, live classroom sessions, billing, and the analytics that tell you any of it worked.

  • LTI 1.3 & OneRoster
  • Real-time classroom
  • Org / seat management
  • Billing & entitlements

05

AI in learning

Applied where it earns its place — item generation, tutoring, speech in and out — with evaluation harnesses and guardrails, because a confidently wrong answer is worse than no answer.

  • Generation + validation loops
  • RAG over curriculum
  • Speech (TTS / STT)
  • Eval & guardrails

06

Growth

Getting a product adopted inside institutions that buy slowly: activation, retention, rollout, pricing and packaging, and instrumentation you can act on.

  • Activation & retention
  • District / school rollout
  • Pricing & packaging
  • Analytics instrumentation
Interactive Manipulatives & Geometry Engine
Interactive Engine

3D Geometry & Calculus Manipulatives

Real-time parameters, vector transformations, and responsive mathematical graphs.

AI Item Generation & Validation Pass
AI & Assessment

Validation Loops & Guardrails

Multi-model item generation verified against strict mathematical and safety harnesses.

Evidence

A platform, not a portfolio piece.

We built a full secondary-maths platform: 416 interactive components across 90 chapters and 7 courses, with 25 item banks, generated practice questions validated by a second model before a student sees them, a real-time multiplayer classroom mode, organisation and seat management, and 66 API surfaces behind it.

You don't have to take that on trust. Every component is extracted, live and playable — open one and move a slider.

The part that blocks deals

Compliance is a market-access problem.

An education product touches children's data, public procurement and accessibility law simultaneously. The rules differ by country, and in the US by state. Most teams discover this during a district security review, or a week before a European launch. We treat it as an engineering requirement from the first sprint, not a document produced at the end.

How we work

Three ways in.

Build with you

We embed with your team and ship alongside it — carrying the parts that need depth: interaction, curriculum tooling, compliance.

You have a team and a roadmap, and a gap in the hard parts.

Build for you

End-to-end delivery of a product or a major surface, from curriculum mapping through to a live platform, with a clean handover.

You have a market and a mandate, and need it built.

Assess & unblock

A fixed-scope audit of an existing product — accessibility, data protection posture, curriculum coverage, technical debt — ending in a prioritised plan.

You're entering a new market, or a deal is blocked on diligence.

Book a call

Fifteen minutes, no deck.

Tell us what you're building and which markets you need to sell into. We'll tell you what's involved — including the parts that usually surface late, like a district security review or an EU launch.

  • What you're building, and who buys it
  • Where the compliance exposure actually is
  • Whether we're the right people for it
