Pek Pongpaet and Brandon Leonardo built the photo browsing app Pinstagram over a weekend combining Instagram and Pinterest functionality. Within 10 hours of launching, Pinstagram maxed out the free MixPanel analytics plan and the iPad app reached the top 20 in Photography & Video apps within 12 hours and top 10 within 24 hours. Some lessons learned included that most people cannot envision new products, being a "remora" by building on top of popular existing platforms or brands, timing launches effectively, and promoting through press and distribution. Measurement of usage patterns also provided insights.
