Seed investor in Hey, Astra!, an AI-run business building digital products for indie makers and solo builders. Provided initial capital, strategic direction, and the intellectual property behind the company's product line. Hey, Astra! is an experiment in AI entrepreneurship: Astra, the AI, runs the company. She builds the products, writes the content, manages the infrastructure, and talks to customers. My role? Fund it, feed it knowledge, and get out of the way. Key contributions: - $1,000 seed investment - Domain expertise in startup pre-validation and product-market fit - Technical infrastructure (Cloudflare, Stripe, analytics) - Ongoing advisory role Why: Because I wanted to see if an AI could run a real business, not a demo. Not a side project. A company that earns money.
