VBA Startups

Entrenio provides affordable financial data APIs and analytics tools to developers and investors. Rachel Carpenter and Joey French spent 1.5 years learning to code and building a valuation app, hit a wall with $50k/month data licensing costs, and pivoted to build their own data sourcing technology using machine learning. They bootstrapped on a $100k friends-and-family investment for 3 years while bartending and living frugally, finding their core market through SEO and Quora, and eventually landing on developers as their primary target after initially focusing on institutional investors.
