About Colin
I'm the founder of Leader's Advantage where I build AI powered tools for investment research and financial analysis including the AI Valuation Assistant. It is a website/platform that automates DCF modeling, ingests SEC filings, and cuts manual modeling time by over 90%. I designed the product, orchestrated the architecture, wrote the code with AI assistance, and shipped it end to end. Before going out on my own, I spent nearly a decade in finance and strategy including earning my CFA charter, managing $500M+ in client assets, and helping grow Mint Mobile more than 5x to a $1.35B acquisition by T-Mobile. I've been the analyst, the strategist, the product lead, and the founder. I know what each of those transitions actually requires.
Why do I coach?
I want to help people develop skills using AI within finance. AI is rapidly evolving and is it is difficult to keep up with the latest changing technology if you do not have the time and are not building with it. By utilizing my program, you will be brought up to 2026's latest methods of utilizing AI in finance and increase more time for cognitive work by utilizing AI and automations.
