I'd love to get Paul Graham's opinion on Shopify. I ran a small business shopping cart software business for a decade and it's really tough market. Small businesses don't want to spend much and are just as demanding as Fortune 500 customers in terms of the features they want. Operating in the red could be fine for a SaaS model if you're growing but the valuation of 1.9B seems high. I wonder how many years Viaweb operated in the red? I wonder if they were profitable when Yahoo! acquired them?
