Demoting A Loyal Friend

When I started Loudcloud, I hired the best people that I knew—people whom I respected, trusted and liked. Like me, many of them did not have deep experience in the jobs that I gave them, but they worked night and day to make it work and they made great contributions to the company. Yet for…

Instagram

Two years ago we invested $250,000 in Instagram. Thanks to the spectacular vision and effort of Kevin Systrom and the Instagram team, the investment will be worth $78,000,000 when the Faceboook acquisition closes. The work that Kevin and team did will go down as legend in the industry and we thank them immensely. We also…

Lies that Losers Tell

When a company starts to lose its major battles, the truth often becomes the first casualty. CEOs and employees work tirelessly to develop creative narratives that help them avoid dealing with the obvious facts. Despite their intense creativity, many companies often end up with the exact same false explanations. Some familiar lies “She left, but…

The Future of Networking

Major technology platforms tend to last about 25 to 30 years. This gives them time to gather sufficient developer momentum, enable a set of transformational ideas, build those ideas, and form a large industry around it. The platforms then sustain for an additional 5-10 years due to inertia and lock-in. Finally, when the shortcomings of…

Why Has Andreessen Horowitz Raised $2.7B in 3 Years?

Since Marc and I founded Andreessen Horowitz three years ago, we have raised $2.7 billion. That statement begs a few questions. The two most obvious are: Why did such a new venture capital firm raise so much money? How did such a new venture capital firm raise so much money? To get to the answers,…

The Freaky Friday Management Technique

Many years ago, I encountered a particularly tricky management situation. Two excellent organizations in the company, Customer Support and Sales Engineering, went to war with each other. The Sales Engineers escalated a series of blistering complaints arguing that the Customer Support team did not respond with urgency, refused to fix issues in the product, and…

Management Debt

Thanks to Ward Cunningham, the metaphor technical debt is now a well-understood concept. While you may be able to borrow time by writing quick and dirty code, you will eventually have to pay it back—with interest. Often this trade-off makes sense, but you will run into serious trouble if you fail to keep the trade-off…

Lead Bullets

Early in my tenure as product manager for the web servers at Netscape, we faced a terrible crisis. We just got our hands on Microsoft’s new web server, Internet Information Server (IIS), and benchmarked against our product.

The New Possibilities

A year ago I wrote about a very special entrepreneur, Christian Gheorghe, who escaped Communist Romania, migrated to America, and—after starting here with $27 as a limo driver and construction worker—eventually became a computer scientist and an entrepreneur. I indicated that just as he broke from an oppressive, totalitarian regime, he planned to free his customers from…

Nobody Cares

This post is dedicated to the late Al Davis. Rest in peace. “Just win baby.” —Al Davis Back in the bad old days when I was running Loudcloud, I thought to myself: how could I have possibly prepared for this? How could I know that half our customers would go out of business? How could…

Management Quality Assurance

Everyone in the technology industry seems to agree that people are paramount, yet nobody seems to be on the same page with what the people organization­—Human Resources—should look like. The problem is that when it comes to HR, most CEOs don’t really know what they want. In theory, they want a well-managed company with a…

Preparing To Fire an Executive

The Fine Line Between Fear and Courage

I tell my kids, what is the difference between a hero and a coward? What is the difference between being yellow and being brave? No difference. Only what you do. They both feel the same. They both fear dying and getting hurt. The man who is yellow refuses to face up to what he’s got…

When Employees Misinterpret Managers

When I ran Opsware, we had the non-linear quarter problem also known affectionately as the hockey stick. The hockey stick refers to the shape of the revenue graph over the course of a quarter. Our hockey stick was so bad that one quarter, we booked 90% of our new bookings on the last day of…

Why the Browser Matters

Before my partner Marc Andreessen and his friends at the University of Illinois invented the browser in 1993, most people thought only scientists and researchers would use the Internet. The Internet was thought to be too arcane, insecure and slow to meet real business needs. Even after the team introduced Mosaic, the world’s first browser,…

Debating the Tech Bubble with Steve Blank: Part I

This post originally appeared as my opening statement in my debate with my friend Steve Blank in The Economist. We are not in a technology bubble. We have not even taken a major step towards a technology bubble. Predicting such things is a bit like predicting the end of the world; the prediction will eventually…
