The 48 startups that launched at Y Combinator S16 Demo Day 2

The world's most prestigious startup school launched 48 companies today at part 2 of its Summer 2016 Demo Day. Nanoparticle analytics and delivery robots were amongst the products revealed in the B2B, biotech, enterprise, edtech, fintech, and hardware verticals. You can check out our write-ups of all 44 startups that launched yesterday, and TechCrunch's picks for the top 7 from the batch. Trying to distill trends from the hodgepodge of startups at Demo day can be futile, because the real winners are the ones ahead of the trends. For example, TechCrunch thought Airware's drone operating system was a little too early in 2013. It turned out to be smartly ahead of the curve. Now you see lots of drone startups in YC, but many are chasing Airware which has gone on to raise 70 million. Y Combinator president Sam Altman explains "The best company at any given Demo Day is not the one that fits the theme of that Demo Day. Altman cites the Alan Kay quote that "the best way to predict the future is to invent it", adding "I think short of that, the future is basically unknowable. What I like about YC is the companies get to invent the future. They don't have to guess." One important development is that 30% of this batch's companies were founded outside the US, a bigger portion than in the past. YC partner Justin Kan credits that to the program being around long enough that it's funded successful companies from tons of countries.
