Silicon Valley start-ups were set to face a great reckoning in 2016. Yet the crash hasn’t happened.

Last year, many tech executives, venture capitalists and entrepreneurs were convinced that a multiyear boom that had propelled young companies to great heights could no longer sustain itself. Some said it would end apocalyptically. Michael Moritz, an influential start-up investor at Sequoia Capital, declared many of the companies “the flimsiest of edifices.” Bill Gurley, a venture capitalist at the Silicon Valley firm Benchmark, proclaimed that the start-ups would bite the dust. “Winter is coming,” others intoned.

The worst fallout may yet come, but many of the start-ups have hung on. Across Silicon Valley, engineers are still commanding annual salaries that average $136,000, according to Hired, a recruiting firm. Demand is brisk for $4 buttered toast, and office space rents remain near record highs. The biggest start-ups, like Uber and Airbnb, continue to land billions of dollars in funding. And investors are shoveling money into venture capital funds, which raised so much cash in the first half of this year that it rivaled the amount raised in all of 2015.

For all of the hand-wringing, “there just hasn’t been much of a downturn,” said Paul Buchheit, a managing partner at Y Combinator, a prominent start-up incubator that nurtured companies including Dropbox and Airbnb. “I don’t even see many companies going out of business.”

That is not to say there has been no adjustment. Some smaller start-ups, like the live-streaming app Blab and the on-demand private chef company Kitchit, have collapsed into Silicon Valley’s dead pool. Other young companies have laid off staff. And many entrepreneurs are no longer able to demand whatever valuation they please for their companies.
