OUR STORY

Built by a teacher. For teachers.

We didn't set out to build a marking tool. We set out to solve the problem that drives talented teachers out of the profession.

"I spent 25 years in the classroom watching brilliant colleagues burn out and leave the profession. Not because they didn't love teaching — because the paperwork mountain was unsustainable."

"When Leanne told me what her Sunday nights looked like — the marking pile — I knew this was a problem that could never be reclaimed. I knew this was a solvable problem."

Restore respect to the teaching profession.

Teachers didn't enter the profession to spend their evenings marking. They entered it to inspire young people, build confidence in mathematics, and change the trajectory of students' lives.

Acrux gives them that time back.

Time is irreplaceable

150–200 hours back per teacher, per year. That's evenings with family. That's professional development. That's staying in the job.

Built for the classroom

Leanne's 25 years in the classroom means every design decision is grounded in how teachers actually work — not how we imagine they do.

Data that drives teaching

Not just scores. Diagnostic insights that tell you exactly which concepts need reteaching, and for whom.

Your data. Always.

Region-isolated infrastructure. Student data never leaves your country or region. No exceptions.
