Theria
I started Theria in 2023 while finishing my Economics degree. At its peak in 2025 it served 950,000 gamers a month across guides, web apps, and community tools, and it has helped more than 10 million players in total. Bootstrapped to consistent profitability through ads, affiliates, and subscriptions. No funding, no big team. Growth was organic: SEO, product-led adoption, and strategic acquisitions.

Technology Consulting
Alongside Theria, I work directly with a small number of traditional businesses in the US, mostly trades and local services, implementing AI and automation into their day-to-day operations: invoicing and receipt processing, financial dashboards, quoting workflows, and custom web systems.
Case study
A landscaping company in Iowa, US
The problem
The owner ran receipts, invoicing, and financial tracking by hand, with hours of admin every week.
What I built
Automated receipt OCR, invoice generation, a live financial dashboard, and a multi-project ledger.
The result
Five figures saved every year, and the owner's evenings back.

Background
I studied Economics & Business Management at the University of Glasgow (MA, 2020-2024). My dissertation, "Virtual Connections, Real Transactions", examined in-game asset marketplaces and laid the groundwork for Theria's marketplace work. Along the way I won competitive scholarships to study in Canada, the Netherlands, Hungary, and Italy.
Before starting my first business whilst at college in 2019, I was a semi-professional eSports player, making decision-making under pressure second nature. Nowadays, I often find myself tinkering with technology, guest lecturing, or speaking at startup events.
