“You can’t anticipate everything. You can’t prep for everything,” said LinkedIn co-founder and former CEO Reid Hoffman during an interview Thursday at the 2021 Inc. 5000 Vision Conference. Entrepreneurship, he adds, is like “running really fast through the fog,” so the best thing you can do is equip yourself with learned wisdom from others who have been down the path before you.

Hoffman, who today is a partner at the venture capital firm Greylock, has had a hand in many fast-growth companies that have achieved enormous scale. In addition to LinkedIn, he was a top executive at PayPal, along with Peter Thiel, Elon Musk, and others who’ve gone on to become household names. And he’s been an investor in Facebook and Airbnb, among others.

Hoffman also is a three-time bestselling author whose newest book, Masters of Scale: Surprising Truths From the World’s Most Successful Entrepreneurs, which he co-wrote with June Cohen and Deron Triff, builds on the success of their podcast by the same name. Both the podcast and the book feature stories and lessons drawn from deep interviews with dozens of famous founders, along with tales from Hoffman’s own career. In short: Few people understand the art of scaling a business better than Hoffman.

In his conference appearance, Hoffman highlighted a few of the top takeaways from the new book and discussed the ethics of Silicon Valley-style blitzscaling at a moment when the type of tech giants he has helped create have come under increasing scrutiny.
