This graph @mhdempsey shared yesterday is the most efficacious single graph representation showing why VC is (or feels) broken atm (absurd capital concentration) Any thoughtful analysis on this topic (that I've seen) agrees (imo correctly), in some flavor, that the structural root cause of exaggerated herd behavior is that VC as an asset class, and specifically the mega platforms, manages way too many dollars (i.e. grown too big). imo it's not a coincidence that the top 10 deals saw 52% of $ invested, while the top 9 funds raised 50% of $ committed As such, I would assert that the downstream deal concentration in VC is a direct consequence of ostensible LP preference for VC consolidated platforms (imo this has both intangible and tangible causes). Investing in more, smaller funds would (I assume) bring investing behaviors back to the mean, but the question seems to be how to break the cycle of fear-induced risk aversion
(New Essay) VC-Backed Startups are Low Status The traditional VC-backed startup path is becoming low status in the same way investment banking did. An aesthetic collapse across institutions, ideas, and founders paired with the world's tiring of tech has recently accelerated this shift. Some thoughts on the cascade, the generational divide, Anthropic vs. OpenAI, what comes next, and more.

“The zero to $100m in a year is the new norm” narrative is getting out of hand. It’s silly, but there’s a breed of VCs who chase speculation driven returns that loooove this talk track. I met a very successful VC recently. He had one of these super hyped startups in his portfolio. He said it’s a wait-and-see for him bc revenues that grow that fast can also shrink in the same speed. He instantly won my respect bc I’ve seen this many times myself. These unnatural early stage growth curves (will call it ultra high growth) happen for a few different reasons. Most of the time there’s a temporary supply demand imbalance for a good that becomes highly in demand over night. There were COVID testing labs that went from 0 to $1b revenue in a year when the pandemic broke. These days it’s the AI infra / compute companies. Initially both demand and prices skyrocket simultaneously which creates ultra high growth. Eventually competition comes in, prices normalize, margins shrink, growth slows down and valuations tank. If you sold your company before that, congrats. There’s a different type of ultra high growth that comes after a long gestational period and a breakthrough. It’s rare. Usually an experienced team who knows the (difficult) problem and customers well is behind them. Pharma biz works this way most of the time. The security company Wiz that got acquired by Google for $32b was another good example. OpenAI is another great example. The reason this pattern isn’t common in tech is improvements usually happen in incremental iterations vs breakthroughs. One problem is companies in the first category try to paint themselves as if they’re in the second category. There may be a 3rd category where a company just goes viral but it still takes a while of hard work to turn that into revenue. It still took TikTok, Facebook, Instagram etc years to become a real business. We forget about the other 100 apps that went to 30m users very quickly and then back to zero. Lastly sometimes it’s possible to spend $70m on paid acq and generate $100m profitably but this category isn’t that interesting. Hyper casual game companies do this all the time. Recap in the next tweet
"Triple, triple, double, double is dead. Going from $1M to $3M to $9M is not interesting. You have to go $1M to $15M to $100M." @chetanp @honam @rabois @jasonlk @bdeeter @ttunguz is triple triple double double dead? Have our growth expectations changed forever?

blockchains are the logical and inevitable home for most 'real world assets' (stablecoins, treasuries, stocks, etc) existing financial infra (correspondent banking, DTCC, etc) solved clearing but it is so hard, slow, and expensive to use chains are digital-native, instant, cheap clearing houses cool to see the RWA adoption and policy momentum

Great honour to be awarded a CBE by the King today for services to AI. Getting the Summit and AI Safety Institute off the ground has been a huge collective effort; I’m so grateful to the incredible team that made them happen (and congrats to @demishassabis and @soundboy!)

He got the Brexit he demanded and his party has been in power for 13 years. Yet not even a flicker of awareness of the responsibility he bears for this mess. It’s hard to find the words to do justice to this kind of bovine idiocy.

100%. The market is so rich and varied. So different from when I started!
Think one of the most important steps you can make as an investor is knowing what is “your type” of deal. This can come in many different slants and doesn’t have to be 100% stuck to. But knowing what is a “Harry type” of deal and identifying fast is important.
