Welcome to another HackerNoon Company of the Week feature. Every week, we highlight a standout company from our Tech Company Database that's making waves in the global tech ecosystem and the lives of its users. Our database features everything from S&P giants to rising stars in the Startup scene. We’ll also be featuring Projects of the Week, so stay tuned to the end.

This week, we’re excited to showcase Learnosity - an assessment infrastructure that is the go-to choice for the best leading learning platforms and educational publishers around the world.

Get to Know Learnosity

Learnosity is a B2B company providing assessment infrastructure to the publishers, platforms, and product teams serving the global learning industry.

Its flagship product, Learnosity Build, brings Learnosity’s assessment APIs together in one API-first engine that covers the whole assessment lifecycle: authoring, item health, delivery, scoring, feedback and reporting. Customers keep their own UX, content and roadmap. Build handles the assessment underneath, along with the scale, security, privacy and accessibility that come with it.

The numbers: 47 million learners, 1.02 billion assessments and 24 billion questions delivered a year.

Build is designed for every team that works on assessment. Now, let’s check out some of those teams.

Content teams

AI-assisted authoring helps content teams create more without sacrificing quality, across more than 50 question types. Item Bank Health Check uses AI to find and fix issues across an entire item bank, from missing alt text to cultural sensitivity and language gaps, keeping content accurate, aligned, and accessible.

Product and engineering teams

Engineers built on one API-first engine for the whole lifecycle: integrate once, deliver everywhere. Build is agent-ready, so teams can work with it directly from AI coding tools like Cursor, Claude, and Copilot. That leaves them free to spend their time on the features that make their product distinctive.

Operations Teams

Operations teams get assessment that runs at the standard their institutions require: burst-ready autoscaling for peak periods, SLA-backed uptime, round-the-clock monitoring, ISO 27001 certification, and compliance with FERPA, COPPA, GDPR and WCAG 2.2 AA.

AI across the lifecycle.

Learnosity’s AI work also covers grading and feedback. Feedback Aide provides accurate AI scoring and written feedback, from short answers to extended essays, at any volume. Learnosity Math is an AI-enriched math engine that can generate question variants and grade open-ended responses. Teams can choose manual, AI, or adaptive grading, aligned to their rubrics and always under human control.

Whatever the team, the model is the same: Learnosity handles the assessment infrastructure, so its customers can focus on the learning experiences that set them apart.
