Powering the Launch of Parlo - A Scalable English Learning Platform.
The Challenge
TEG approached us to support the launch of Parlo, a new English language learning service built around immersive video content. They required an end-to-end solution to bring the idea to life: from proof-of-concept to scalable delivery, across mobile and web.
The Solution
We started by working closely with TEG to understand the learner experience they wanted to create. From there, we designed and built a fully integrated digital learning platform, including:
- A mobile app for learners (iOS & Android)
- A web-based CMS for content creation and publishing
- A robust technical architecture to support growth at scale
Starting with rapid prototypes, we proved the technical feasibility of embedding interactive elements directly into video episodes - creating seamless, in-video learning experiences. From there, we developed a flexible system of interaction types and content workflows, enabling content teams to author rich, modular lessons with ease.
Key deliverables included:
- Functional prototypes
- UX flows and wireframes
- App & CMS UI design
- Service design
- Technical architecture
- DevOps infrastructure
- Application build (iOS & Android)
- CMS & publishing workflow
Impact
Following development, Parlo launched its first international rollout in Brazil, achieving strong early traction:
- 300,000+ installs on Android devices
- 25,000 downloads in the past 30 days alone
- Rated 4.0★ on Google Play (750+ reviews)
- Rated 4.6★ on the App Store (UK)
Learners praise the app for its intuitive design, engaging content, and ability to teach practical English in real-world contexts.
Engagement Highlights:
- 100+ video-led lessons and 200+ interactive activities
- Built-in voice recognition for fluency and pronunciation
- Real-world learning scenarios (e.g., ordering food, asking directions)
- Structured paths designed by London-based educators
The first content episodes are available free!
