Sam Altman tweeted: "it's amazing how much a team can accomplish in 3 months with a little money and no distractions"<p>This got me thinking.<p>How much progress do YC companies make during their 3 months?<p>What is the mean/median progress for product development? How much product development does the best in a batch make?<p>Same question about mean, median and max for business progress? How much revenue? How many customers? etc.<p>The best approximation that I've found is:<p>week #2: 1st prototype<p>week 7/8: Start selling<p>week 10: Prototype Day and start prepping presentation for Demo Day<p>Week 12: Demo Day
