Education. Individuals. Business. One connected 21C ecosystem.
Choose your path
Education
Tools and delivery support for schools — built for real-world constraints, not ideal conditions.
Individuals
PocketMaths and pocket learning products designed to build confidence through short lessons, practice and progress you can see.
Business (Avatars)
Avatar-led communication and interactive training that scales consistent support across your organisation.
Why we exist
We started in education because access to understanding is still uneven — and when support is stretched, the people who need it most are often left behind.
That is why we built products such as PocketMaths: to make practice feel manageable, progress visible, and support more consistent.
What we learned there applies more widely. In every sector, important information is shared every day — but it is not always understood, retained or acted on. 21C exists to solve that problem properly: by designing communication and learning experiences that are clearer, more engaging, and easier to scale.
From “sent” to understood
Most internal communication fails quietly. It is skimmed, ignored, or forgotten. Avatar-led video brings back human presence, with the speed, consistency and scalability organisations now need.
95% retention
Viewers retain 95% of a message via video, compared to 10% via text.
60,000× faster
The brain processes visual information 60,000× faster than text.
75% preference
Employees are more likely to watch a video than read a document.
From message to mastery — delivered at scale
We engineer written content into engaging avatar-led video — and when comprehension must be verified, we build interactive SCORM assets delivered through an LMS with analytics.
The Mastery
Interactive SCORM learning assets with verification — questions, branching and assessments — delivered through an LMS.
Enterprise Twin & Managed Learning
Digitise key people and build tracked learning environments for demanding clients.
Yes, you can do it yourself. Most teams don’t have the time.
You can buy great tools and build everything in-house. In the same way you can refurbish your own house, some people will do an excellent job. The question is whether you want a result that is merely done — or one that is designed to work.
At 21C, we combine Synthesia-powered avatar video with the expertise and infrastructure that turns content into outcomes.
Use your own people as a digital Enterprise Twin, or select from an avatar library to fit budget and speed.
- Message engineering — we shape scripts for clarity and retention, not just reading a document on screen.
- Instructional design — we build learning flow that keeps people engaged and moving forward.
- Interactivity + verification — SCORM packages with branching, hotspots and assessments, delivered into your LMS.
- Analytics — track completion and results through your LMS reporting.
- Fast updates — when policies change, we update the text and regenerate the asset without re-filming.
- Multilingual rollout — translate and deploy across teams consistently where required.
A connected ecosystem — not one-off projects
We build reusable assets that work across sectors — learning content, practice environments and scalable delivery through automation and analytics.
One ecosystem. Different entry points.
