A* AI

I co-founded A* AI in 2025 and serve as its Chief Marketing Officer, responsible for growth and distribution.

Generic AI knows the subject but not the exam. It can explain a concept correctly and still lose marks, because it doesn't know what a board rewards or how examiners band a response. A* AI is built by students who sat those exams and got the top grades: it marks essays against official banded criteria, generates labelled diagrams, and pulls questions from a searchable past paper bank across 30 subjects. I built the GPT workflows behind it and lead feature prioritisation from user feedback.

10,000+users since October 2025

Revenue is concentrated in the spring examination period, which shapes how we plan releases and marketing spend across the academic year. In early 2026 we placed in the top 3% of 200+ teams at Imperial IdeaForge.

The first 1,000 users came without paid acquisition. Beyond that I built and managed a network of 30 content creators across 4 time zones, generating around 250,000 views a week across TikTok and LinkedIn. Managing that channel has been the substance of my role.

High School Clean Investment Coalition

Persuading a school to change its investment policy is a governance problem rather than a financial one. The arguments are not especially difficult. The difficulty is that the decision sits with a bursar or a finance committee who did not ask the question and have no obligation to answer it.

The High School Clean Investment Coalition is structured around that constraint. It is a student-led organisation, now comprising 51+ member schools across 11+ countries, campaigning for secondary schools to divest from fossil fuels and reinvest in clean energy. Rather than lobbying schools externally, it enables students at each institution to raise the question internally, where they have standing.

I served as UK and International Lead, responsible for the coalition's growth beyond its founding schools. In practice this meant recruiting member institutions, establishing student teams, and preparing them for conversations with their own governing bodies. I developed the campaign materials they used and briefed them on the arguments a finance committee would expect. I also trained 20 school teams on endowment engagement and divestment strategy, expanding the model into 8 new countries.
