Learning products often start fast and slow down as classes, content and schools pile up. These are the gaps that lose students and renewals.
Pages and games load slowly on school networks, and students give up before the lesson starts.
Performance work first
We find what slows the platform down, fix it without taking it offline, and keep checking after.
Results arrive after the lesson, in exports nobody has time to read.
Real-time teacher dashboards
Scores and progress for each class and each student, as they happen.
Schools on different subscriptions see the wrong upgrade options, or lose access they paid for.
Reliable plans and billing
Family, class and whole-school plans that give each school exactly what it bought.
Courses built in one system cannot move to the LMS a school already uses.
Standards-based content
Courses packaged as SCORM or xAPI, and tools launched from the LMS with LTI.
Six products, grouped by who uses them. Each one can be built on its own or connected to the rest.
Learn
What students open every day.
Courses, lessons and assessments, for one school or thousands of learners.
Quizzes, study games and apps that turn practice into play. See our mobile app development.
Teach
The tools behind the lesson.
Classes, assignments and live results for teachers, with a view for school leaders.
Shared libraries of lessons and questions, tagged by subject, grade and standard.
Run
Accounts, plans and numbers.
Plans for families, classes and whole schools, with sign-up, billing and seat management.
Usage and results turned into reports for teachers, schools and your own team. See our data analytics services.
A game-based study platform we took over and made fast, and a skills platform with structured courses and an admin console.

A skills platform with structured courses, expert content and a console for L&D teams.
24% boost in community engagement
They have gone above and beyond simply being developers. They feel like partners who are invested in helping me build something great.
Student data and accessibility are handled inside the software, not after launch. This is what one student account checks before it goes live.
Rules differ by country, by school and by age group. They are set as configuration, not written into the code.
Students, teachers, parents and admins see only their own part.
Built with FERPA, COPPA and GDPR requirements in mind.
WCAG 2.2 AA checks on every screen, games included.
Google or Microsoft school accounts, or your own login.
Every change to scores and accounts recorded.
Pages and media sized for shared classroom connections.
Schools already run an LMS, a student information system and a sign-in provider. We connect to them so classes and results move without re-typing.

Five stages, with teachers and students trying each flow before launch. You see working software every sprint.
We learn how teachers, students and schools use the product before we propose changes, so ideas arrive with the fixes.
For a live product we trace what slows it down and rank every issue with its own estimate. For a new one we design the learning flows and the data model.
Features ship in short sprints, with every screen checked for speed and accessibility as it is built.
Teachers and students try each flow on the devices and networks they use before it goes live.
After launch we monitor the platform, fix issues before they are reported and bring ideas for the next term.
Three ways to start. Every one begins with a free call with an engineer, and an NDA before we see anything confidential.
A team that works only on your product, inside your processes, tools and time zone.
Best for Long-term products whose requirements keep changing
Developers who join your existing team to fill a skill gap, without full-time hiring.
Software developers Full-stack developers
Best for Teams that need to scale up or down quickly
A detailed plan, timeline and cost agreed upfront, with delivery managed end to end.
Best for Projects with a clearly defined scope

Yes. That is how our work on Subjects Master began: site speed and performance first, then other issues, then new features. We audit what slows the platform down, rank each issue by severity and estimate each fix before we start.
Yes. We design and test to WCAG 2.2 AA, including keyboard use and screen readers, so every student can use the product.
Yes. We package content as SCORM or xAPI, launch tools from the LMS with LTI 1.3, and read class lists from student information systems, so teachers do not enter classes twice.
We collect only what the product needs, give every role its own view, encrypt data in transit and at rest, and build with FERPA, COPPA and GDPR requirements in mind.
Yes. We size and plan the work so a founder can move the product forward without surprises, and every fix comes with its own estimate.
Our team is based in India, the United States and Germany, which gives you working-hours overlap across Asia, Europe and North America.
Three ways, matching our engagement models: a dedicated team billed monthly, staff augmentation where you add individual engineers to your own team, or a fixed-scope project with an agreed timeline and budget. The first consultation is free; we scope your requirements there and quote after it.
Security is built into every engagement: data encrypted in transit and at rest, role-based access control, logging and monitoring, and audit-ready configuration. For regulated industries we design to the relevant standard. We sign an NDA before any engagement, so your systems and data stay confidential from the first conversation.
Share your requirements and an engineer will reply within one business day with next steps.
