Twitter lawyers: Musk destroyed Andreessen evidence

Court filing0 Comments

Twitter’s lawyers have accused Musk of destruction of evidence, citing a screenshot of a conversation between Musk and venture capitalist Marc Andreessen on Signal, a messaging app that includes a feature that deletes messages after some time.

Musk deleted these messages because he anticipated litigation and he knew that they would undermine his counterclaims and defenses.

The same court filing also showed that Musk exchanged multiple text messages with Oracle Corporation co-founder Larry Ellison, starting May 12 through 12:20 a.m. on May 13, which was just hours before he announced that he was pausing his attempt to acquire the social media company.

Twitter’s legal team has complained that despite a subpeona, the Tesla CEO has not really provided the relevant text messages between Musk and Ellison.

Both Ellison and Andreessen have backed Musk’s attempt to acquire Twitter. Andreessen’s VC firm, Andreessen Horowitz, backed Musk with $400 million, while Ellison was one of 19 investors who committed a whopping $7.14 billion for the potential acquisition.

Recode podcast

Interview0 Comments

Andreessen talks with Swisher on Re/code Decode about bubbles, politics and parenting.

When I first came out here [Silicon Valley] I thought that I had missed all the excitement. I thought that the PC had happened and I thought that was it, and I thought that we were just going to play cleanup after the PC. And then the internet supernova happened and this new universe has opened up. For me that was a big shock. The opportunities for this industry are just so much bigger than they used to be. We see kids coming here in their early 20s and every now and then they’ll say ‘Boy, I wish I was here in the old days when everything was happening’ and I think they’re all going to be sitting in these chairs 20 years from now, saying the same thing, ‘Oh it was so crude an primitive back then’.

New Yorker profile

Interview0 Comments

Andreessen and Andreessen Horowitz are profiled in an article in the New Yorker titled, Tomorrow’s Advance Man.

Entrepreneurs want to raise money from us, so the natural thing when we say ‘What if you did this?’ is to tell us what we want to hear. But we don’t want to hear what we want to hear. It’s a delight when they look at you with contempt—You idiot—and then walk you through the idea maze and explain why your idea won’t work. At the same time, we’re not funding Mother Teresa. We’re funding imperial, will-to-power people who want to crush their competition. Companies can only have a big impact on the world if they get big…Deal flow is everything. If you’re in a second-tier firm, you never get a chance at that great company.

Breakthrough ideas look crazy, nuts. It’s hard to think this way—I see it in other people’s body language, and I can feel it in my own, where I sometimes feel like I don’t even care if it’s going to work, I can’t take more change. O.K., Google, O.K., Twitter—but Airbnb? People staying in each other’s houses without there being a lot of axe murders?

Chris Dixon argues that we’re in the magical-products business—that we fool ourselves into thinking we’re building companies, but it doesn’t matter if we don’t have the magical products. Over twenty years, our returns are going to come down to two or three or four investments, and the rest of this [gestures at the building and staff] is the cost of getting the chance at those investments. There’s a sense in which all of this is math—you just don’t know which Tuesday Mark Zuckerberg is going to walk in.

New York interview

Interview0 Comments

In a wide-ranging and detailed interview with New York magazine, Andreessen talks about Silcon Valley culture, discrimination, his favorite TV shoe (Deadwood), and the ideal of meritocracy:

I believe the ideal is compromised by two things right now: One is educational skills development, and the other is access. This is the critique that I think is actually the most interesting, which is, yeah, the meritocracy works if you know the right people, if you have access to the networks. How do venture capitalists make investment decisions? Well, we get referrals based on people we already know. Well, what if you’re somebody who doesn’t already know anybody, right? What if you don’t know the recruiter at Facebook so you can’t get the job? What if you don’t know the venture capitalist so you can’t raise funding? We think access is broadening out the network so that everybody who could contribute can get access to the network. And that’s the one that we’re working on.

Warns cash-burning startups

Makes Statement0 Comments

When market turns, M&A mostly stops. Nobody will want to buy your cash-incinerating startup. There will be no Plan B. VAPORIZE.

‘The IPO is dying’


In an interview on Vox, Andreessen claims that laws such as Sarbanes-Oxley and Regulation Fair Disclosure are placing such burdens on successful startups that they are wating longer to go public, depriving the public markets of growth.

The compliance and reporting requirements are extremely burdensome for a small company. It requires fleets of lawyers and accountants who come in and do years of work. It’s this idea that if you control everything down to the nth detail, nothing will go wrong

The loop we’re in now is that people are getting upset and disappointed by the stock market. There are no growth stocks, which means there’s no growth. Stock market returns have been flat for 15 years, which is exactly what you’d expect if you took all the growth out. Everyone is upset the stock market isn’t performing. The worse the results get, the more regulation you get. It’s in its own kind of doom loop. Unless something happens to shock the system a lot, our assumption is it gets worse, not better.

He also criticizes Tomas Piketty’s book, Capital, saying that the investment results that Piketty says drive inequality are exaggerated:

The funny thing about Piketty is that he has a lot more faith in returns on invested capital than any professional investor I’ve ever met. It’s actually very interesting about his book. This is exactly what you’d expect form a French socialist economist. He assumes it’s really easy to put money in the market for 40 years or 80 years or 100 years and have it compound at these amazing rates. He never explains how that’s supposed to happen.

Not sorry for Tweetstorms

Snowden ‘Traitor’


Andreessen calls Snowden a traitor, a viewpoint he claims is a minority view in Silicon Valley:

For me obviously he’s a traitor. If you look up in the encyclopedia ‘traitor,’ there’s a picture of Ed Snowden. He stole national security secrets and gave them to everyone on the planet.

Andreessen also continuies his criticism of President Obams response to the NSA revelations, noting there is no plan to help American companies that do business overseas:

As far as I can tell there’s no plan, there’s no strategy, there’s no tactics, there’s nothing. The Snowden reveals keep coming out. The [Obama] administration is letting the NSA out to dry. They’re letting the American tech industry out to dry.

Beware high-value out-of-towners


Andreessen says he is warning portfolio companies to be skeptical of early-stage investments with high valuations as investors from outside Silicon Valley, who he doesn’t name, are acting unethically. He says they are often presenting term sheets as a start to negotiations rather than an end-point, and pushing valuations sky-high to get exclusivity on deals, increasing the risk for the startup if the investor walks, and making it harder for the investor to get future deals.
