Meet Our Founders

Two people with a shared vision: making education technology that actually works

Zak Hajjaji

Founder & CEO

Zak is a developer and founder focused on building intelligent tools that make a real difference in the classroom. His work on Lingjo is driven by a clear vision: use AI to remove the unnecessary workload that holds teachers back, while improving the way students learn and progress. With a background in product and systems thinking, Zak brings a straightforward approach to education technology.

Alfie Williams

Co-Founder & CTO

Alfie's career has been deeply rooted in education and adjacent fields. His experience as an ESL teacher in Spain shaped Lingjo's core philosophy: to genuinely help students while supporting the teachers who carry immense responsibility and stress. Alfie is an experienced software engineer focused on building practical tools for educators, language learners, and students alike. Lingjo is his latest project, built to address what he faced as a teacher and learner.

"We founded this company with a simple belief: technology should work for people, not the other way around."

"After teaching ESL in Spain, I saw firsthand how much pressure teachers face. That's why Lingjo exists—to genuinely support both students and the teachers who dedicate themselves to helping them learn."

Our Story

Born from Real Experience

Lingjo was born from experience. Co-founder Alfie Williams spent most of his professional life working in education and adjacent fields, including years as an ESL teacher in Spain. It was there that he witnessed the daily pressures teachers face—the desire to genuinely help every student while managing overwhelming workloads and stress.

That experience became the foundation of Lingjo's philosophy. We don't just build tools for teachers; we build tools that understand the real challenges educators confront every day. Our mission is to support both students and the dedicated teachers who guide them.

Today, Lingjo continues to evolve, always rooted in the understanding that technology should serve people—especially those who serve our students.

What We Stand For

Our core values guide everything we build

Teacher First

Every feature we build starts with understanding what teachers actually need, not what we think they need.

Practical Innovation

We use AI to solve real problems, not to create flashy demos. If it doesn't save you time, we won't build it.

Student Success

Our ultimate goal is helping students learn better. Everything we do is measured against that standard.
