$500 to $10M: Building 4 E-commerce Brands While Working Full-Time

TL;DR: Karthik and his co-founder Luke started Greek House in 2013 targeting custom apparel for fraternities and sororities. They bootstrapped with $500, leveraging their campus network for initial sales while Karthik worked full-time at Amazon (overnight shifts) and Salesforce (8am-5:30pm + evenings). Year 1 hit $50K, year 2 hit $100K. In 2016, Karthik went full-time and faced a $40K licensing audit bill 4 months in - they negotiated a payment plan and turned the crisis into an opportunity by getting 300+ college licenses. The key to their growth was building custom tech (order management platform, vendor portal, customer portal) that made them 10x easier to work with than other distributors. This allowed them to secure premium print partners and deliver 2-3 day turnaround while competitors took weeks. They expanded into 4 brands by following their customer base: Greek House (fraternities/sororities) → College Thread (campus departments) → Threadly (corporate custom) → Athlete's Thread (NCAA NIL merchandise). Their distribution strategy evolved from manual outbound (texting friends, pitching at student org meetings) to affiliate programs to paid search to marketplace aggregation (Etsy, Google Shopping). The licensing moat - requiring both college licenses AND athlete NIL rights - eliminates 99.99% of potential competitors.
