Launched Sauron, the future of home security at Art Basel Miami. We’re building the only platform that reliably identifies, understands, and deters threats. Wouldn’t be possible without my co-founders @jackabraham and @likeavass. More soon!
I have noticed over the years that the best companies always tended to have rodent infestations. Lots of builders ambitiously crowded into a relatively small space spending 24/7 eating, sleeping and coding. It’s a recipe for mice.
No part of this is OK. LARPing freedom fighting doesn’t make these vandals anything better than what they are: criminal antisemites.
Last night, under the cover of an anti-ICE protest, agitators forcibly entered and vandalized @welcometomannys, a beloved Jewish-owned civic engagement hub and community space. This wasn't an isolated incident; @manny_yekutiel and his establishment have been subjected to a…

Goldman's China robotaxi TAM forecast. Just wow
Ok Chad (aka ChatGPT 4.5) calculates it would require 100k Waymo’s to accommodate sf rush hour and would need more for even larger surges so I’ll say robo taxis + public transport.
People really avoid answering that question.
I can’t answer that but do know they will accommodate 6’ 9” old cranks. What!?
Will they build for peak or average usage?
Yes in the near future you will sell your car for inexpensive safe self driving cars run as a service and @jobyaviation is where I bought my flying car.
So you’re saying in the near future (our life times) we will ban private vehicle ownership so we can get around in Waymo pods. Love the bold vision but if you believe that I have a monorail and some flying cars I’d also like to sell you.
This is an antiquated perspective. An autonomous fleet needs a fraction of the cars of a population and car ownership would end.
The best cities in the world have efficient mass transportation options that most everybody uses (safe, clean, frequent). Cars don’t scale due to their space inefficiency and AVs unfortunately don’t change this reality.
San Francisco is a “car city” but will be one of electric robo taxis. This is a fantastic outcome and the die is already cast. It is just a matter of time. sfstandard.com/2025/07/26/san…
Ramtin is a close friend and an undeniable force of nature. Thrilled for more people to hear his remarkable story. @ramtinnaimi @AbstractVC
Ramtin Naimi started a successful hedge fund at 19, went bankrupt at 24, and then built a $1.8 billion venture firm backed by investing icons like Stanley Druckenmiller, @pmarca, and @BillAckman. Michael Ovitz calls Naimi his “non-biological son.” Founders say he’s “the most…

decagon.ai/resources/seri… Decagon raises series C at $1.5B valuation
I have no affiliation or investment in Ramp but they seem to have a lot of product-market fit amongst my startups and family office!
Today @tryramp announced a fundraise at a $16b billion valuation. My partnership with @eglyman, @karimatiyeh and Ramp dates back to 2019 when I met Eric in a NYC coffee shop the morning after he incorporated the company. By the end of the day, I had committed to investing. It…
Inspired by @ColeRotman, we looked at the seed rounds of all the AI Unicorns founded post transformer. Interestingly, none have come out of YC, and no one except a16z has led or co-led more than 2 seeds. ~20% of the founders pivoted to their current businesses.
