Prep Edu: Five Years of Building, One Million Learners Strong

In 2021, Prep Edu launched with a conviction that personalized, intelligent support was what language learners actually needed. Five years, seven products, and one million learners later, that conviction has paved the way for Prep Edu to become one of Asia's most recognized EdTech platforms.

From Classroom to Platform

Prep Edu is an AI-powered language learning, teaching and testing platform. Founded by Tu Pham - an educator with two Master's degrees from top UK universities and over a decade of teaching experience - the platform was designed around a single goal: make every learner feel like they have a dedicated personal tutor.

Today, Prep Edu supports learners across five markets with a course portfolio that covers the full range of language learning needs: Prep IELTS, Prep TOEIC, Prep HSK, Prep VSTEP, PrepTalk, Prep IELTS Junior and Exam Platform - each was built to lead in its category.

“At Prep Edu, we are focused on how AI can make language learning more personal and accessible. We understand that technology alone is not enough. Meaningful education also requires a deep investment in content quality. That’s why Prep Edu is dedicated to personalized, value-driven learning experiences that empower real results” - CEO Tu Pham highlighted Prep Edu’s role in advancing AI-driven language assessment at EdTech Asia Summit 2025. 

What Five Years of Building Looks Like

One million learners. 113 million minutes of learning logged annually (That's an average of 215 learners studying on Prep every single hour!). Over 140,000 questions answered by Teacher Bee AI. 23 million sessions completed in Prep AI's virtual exam rooms. And throughout all of it, a target score achievement rate of over 90% among all learners - a figure that holds across every exam, every market, and every learning background that Prep Edu serves.

Ja, a Prep Edu learner from Thailand shared: “I had no regrets choosing Prep Edu. Throughout the journey, I gained a deeper understanding of my own strengths and weaknesses. I had achieved exactly what I set out to do. My score jumped from 6.5 to 7.5 in just a month, a significant improvement that proved how effective Prep Edu’s methods truly are.”

Behind those outcomes is a comprehensive AI-powered product suite built across seven products and 400+ learning modules: Teacher Bee AI for 24/7 lesson support,  PREP AI VSR VWR for real exam simulation with instant feedback, and two proprietary technologies - Accurate Scoring AI  & Corrective Feedback AI - for full-length performance analysis.

These technologies score 0.90 on the Quadratic Weighted Kappa (QWK) scale, the industry standard for inter-rater reliability, while  certified human examiners score 0.91 and general-purpose AI tools like ChatGPT score 0.72. For learners, that 0.01 gap from human-level accuracy means they can expect results from Prep Edu to reflect their real abilities - and move forward with confidence.

Recognition That Reflects the Work

The broader EdTech world has taken note. Over the past five years, among others, Prep Edu has been celebrated as:

• Top 50 Most Promising EdTech Startups in Southeast Asia - HolonIQ (2023, 2024 & 2025)

• Most Promising & Pioneering AI -powered Application in Education -EdTech Asia 2023

• NextGen Tech 30 Award 2024 - Granite Asia, recognizing top breakthrough tech companies in ASEAN

• Joint Highest Growth in East Asia 2026 - IELTS Global Partner Gathering

For a platform that started as a single classroom, these milestones reflect a journey that few dared to imagine at the start - and one million learners helped make real.

To the Million. And Beyond.

Behind every number in this article is a learner who chose to trust themselves - and chose Prep Edu to back that trust. One million times over. Each learner is proof of what Prep Edu has built, and a reason for Prep Edu to keep redefining learning, teaching, and testing. 

Five years in, the mission remains unchanged: helping every learner make it happen. One million learners is a significant marker, and for Prep Edu, it also represents the launchpad of a much longer journey.

Here’s to the next million!
