the momentum/late stage investors have moved from consumer to enterprise. there is a large pool of money in the venture capital asset class that is opportunistic, momentum driven, and thesis agnostic. this pool is driven largely by the public markets. this pool of capital was "all in" on consumer web/social web in the 2009-2011 time frame. it drove a lot of activity throughout the venture capital markets because each layer of the VC stack (angel, seed, Srs A, Srs B, Srs C, etc) needs to be aware of what the next layer up wants to fund. when the momentum/late stage wanted web/social, the layers below gave them web/social. now that the momentum/late stage wants enterprise, we should expect the layers below to give them enterprise.

Fred's right, everything has changed.

Investors want you to do not only Web but also iOS and Android:

Most new consumer internet startups need to build for iOS, Android, and web at the same time. it is making the startup more expensive and time consuming. distribution is much harder on mobile than web and we see a lot of mobile first startups getting stuck in the transition from successful product to large user base. strong product market fit is no longer enough to get to a large user base. you need to master the "download app, use app, keep using app, put it on your home screen" flow and that is a hard one to master.

However, you really can't have a good mobile app without also having a Web version.

Pinterest and Tumblr grew on the Web, not on mobile.

I do agree with the basic point -- it's hard to break-out in consumer Web:

The consumer web has matured. we are almost 20 years into the consumer web and we have large platforms that are starting to suck up a lot of the oxygen. google, facebook/instagram, amazon, microsoft, apple, twitter, ebay, yahoo, AOL, craigslist, wordpress, linkedin together make up a huge amount of the time spent online, particularly in the english speaking world. there are still occasional new entrants into this list and departures too. tumblr and pinterest have risen a lot in the past couple years while myspace has declined. but consumer behaviors are starting to ossify on the web and it is harder than ever to build a large audience from a standing start.

I wonder what 5-10 years from now will be obvious in retrospect that isn't obvious today.

Tumblr, Pinterest, and Instagram were all breakout hits in the last three years.

Certainly there will be others.

Who says startups are easy?
