A short history of ESL EdTech
For most of the last 15 years, ESL EdTech has been three things:
- Quiz tools. Kahoot, Quizizz (now Wayground), Baamboozle, Blooket, Gimkit. We've broken down the shared DNA of these tools and why they don't build speaking.
- Self-study apps. Duolingo, Babbel, Memrise. Designed for solo learners outside a classroom. Useful for vocabulary; not designed for classroom use.
- Generic productivity tools repurposed. Google Slides, PowerPoint, Padlet, Canva. Useful for lesson preparation; not actually doing the teaching.
What was conspicuously missing: a tool designed from scratch for the central activity of an ESL speaking lesson. Pair students. Give them topics. Time their conversations. Repeat. The whole loop is mechanical, repetitive, and entirely automatable - and for a decade nobody automated it.
Teachers filled the gap manually. Lists of conversation questions in a Google Doc. Manual pair-swapping. Stopwatch on the phone. The speaking lessons happened, but the cognitive overhead on the teacher was enormous. Some teachers gave up and reached for the quiz tool that was already in their toolkit, even knowing the maths didn't work.
Why the category didn't exist sooner
Several reasons converged:
The market looked similar to general EdTech. From outside, "ESL tools" looked like "EdTech with English content". Investors and founders saw a vertical of an existing market, not a structurally different one. So they built quiz tools with English content and called them ESL tools.
The structural requirements weren't obvious. It took the maturity of ideas like Willingness to Communicate and the
parallel/serial speaking distinction to make it visible that the limitation in ESL EdTech wasn't content quality but structural design.
Single-screen classroom orchestration is hard. Building a tool that runs the whole class on one shared display, with pairing logic, topic selection, timing, and optional gamification, is harder than building a typed quiz that runs on student devices. The engineering investment looked unjustified to most EdTech founders.
Teacher demand was diffuse. Teachers who needed the tool didn't necessarily articulate it the same way. Some asked for "a speaking app". Some asked for "a way to manage pair work". Some asked for "Kahoot but for talking". The diffuse demand made the category hard to see from the outside.
The category gap is real but it's only obvious in retrospect.
