I had a provisional place in medicine. I gave it up because I ran the numbers on impact, and they pointed at education. Edexia is what came out of that. We help schools give students fast, consistent, rubric-aligned feedback on their writing, across English and HSIE subjects: History, Legal Studies, Business Studies, Economics, Society and Culture, Studies of Religion and more. After speaking with hundreds of teachers, we learned that the biggest challenge for school leaders was scattered consistency across a faculty, compromised student integrity in an age of AI, and the workload that pushes good teachers out of the profession. We built Edexia to fight against all three. The teacher is always in control. Edexia drafts a rubric-aligned grade and feedback, the teacher reviews, edits and approves, and nothing reaches a student unapproved. Blind grading and moderation show you where two markers disagree, so a head of department can hold a whole cohort to one standard. Edexia has also become a professional development tool too, because calibrating against expert standards lifts newer and graduate teachers. It works. Across 579 essays, Edexia agreed with the teacher's exact grade 81% of
