[Altimeter Capital @AltimeterCap]

Congrats to @tuhinone Srivastava and the entire @baseten team on their $1.5B Series F led by Altimeter partner Apoorv Agrawal (@apoorv03). Approximately 20x revenue growth and 1B+ inference calls a day. The inference market is compounding fast, and Baseten is where some of the most sophisticated AI companies are standardizing. Proud to co- lead this round with @conviction & @sparkcapital and partner with this amazing team! 🚀

in markets, to go long on something is to bet it grows more valuable over time. much of the conversation today is short on humans, wagering that ai makes people redundant. we believe the opposite is true for the industries @ThriveHoldings operates in.

we are long humans.

We are thrilled to lead @AnthropicAI Series H!

Anthropic is making intelligence ubiquitous and transforming how industries are thinking about operating. We have been in awe of their capacity to metabolize hard things and make it look easy, whether that's unlocking research breakthroughs, shipping products, or driving compute efficiency.

We believe the Anthropic team has built something rare: a culture where mission, talent, and velocity are perfectly aligned. That foundation allows them to redefine what’s possible in AI.

What also stands out is the simultaneous speed and precision of their execution. Claude has become the default operating system for entire enterprises, powering coding, reasoning, and complex workflows at a scale we've never seen before. We believe their ability to ship high-performance systems while also pushing the frontier on safety and alignment is unmatched.

Huge congrats to the entire Anthropic team. Deeply honored to continue to partner with you as you continue to set the standard for what safe and powerful intelligence can be. What Anthropic has accomplished is one for the history books, and yet the best is still ahead. 🚀 @altcap @paulinebhyang @ayanagarwal0

given the vague post is blowing up, i want to tell you all a story from last night in nyc and where i think the world is going.

last night, i went for a long walk as i felt quite existential about my business. i stopped into a restaurant. they had one last seat at the bar. i was sat next to a new friend, also 23, that teaches chess to kids and resells vintage clothes.

he asked what i did after i peppered him with questions. i told him i just make chatgpt work for businesses. he could go into the actual chatgpt app and it would know what recent lessons he gave, how he communicated with clothing suppliers, and actually do the monotonous work for him. no setup, no management on his end.

he was fascinated and open to the idea. we sat next to each other for hours and ended up talking about the implications of ai, the fear of joblessness many of our friends experience postgrad, and the meaning crisis if everything is automated (but how good the bartender's aux was, how she nearly went to deep springs college, and nascar drivers).

i generally agree but still hold that ai is the most empowering technology ever bestowed upon humanity. the gap is only engineers and pseudo-technical people can make it truly work for them in the interfaces people are comfortable with (ChatGPT/Codex & Claude). we sand down the rough edges to make the models understand our context across imessage, notes, and disparate systems.

now, step back for a minute and put yourself in your parents' or grandparents' shoes. think about the monstrous software they must battle everyday to get their job done. the legacy ERP that takes 45 minutes to process an order (i just learned what an ERP was 2 months ago).

it is obvious to me that the labs will continue pushing models up the exponential. they will make it easier for people across the country and the world to build with ai, have the models automatically surface workflows and automations for monotonous work. however, we are a ways away from this.

you, dear reader, have the unique skill set to direct codex to solve the problem. to build the integration that "just works" then to store the proper memories so it can do it faster and knows who your dad is and how he works. this technology should "just work." it is literally intelligence in a box; ai is the most malleable technology humanity has every experienced. make it so.

i hope this causes many businesses of my shape to spawn up.

go do this for the 3 businesses you know. go do this for your parents to help them have more free time to focus on what they actually love doing (i can almost assure you it is not manually inputting data into an ERP).

i have no idea if this is a "venture sized" outcome. candidly, i do not care. the largest impact i think you and i can have is to deliver on the promise of ai. it is the most human technology we have ever created.

intelligence that understands you, your parents, and your grandparents. intelligence that never tires, that handles the monotony no human wants to do, so we can focus on what is truly human -- serving others.

Great piece from @MaximilianMona! He and the Ironsite team have a unique empathy for their customers, as many of them have worn the boots

Taught my first class at Stanford Engineering yesterday. "Economics of the AI Supercycle"

Condensing everything I've learned investing across the AI stack into a course. Nothing sharpens your thinking like teaching it to brilliant students.

Packed room, great questions, blown away by the caliber of students from across the university. This is going to be a fun quarter.

The High-Power Era in space has begun. 

20kW on orbit. A fundamentally new class of spacecraft.

Huge milestone for @K2SpaceCo on Gravitas.

Ads > Subs (!)

Ads for AI may be bigger than subs. That's the main finding of Part 3 of "State of Consumer AI" series.

Why? Ad Revenue = Time × Ad Volume × Ad Price. All rising. But the most interesting variable is price. "Recommend a laptop under $2k for video editing," on ChatGPT has richer intent than a Google search. Budget, preferences, constraints, all in one prompt. Logged in, so attribution is clean.

And bonus, consider AI-native ad formats: conversational ads informed by memory, agentic purchasing, personalized brand moments that feel like features, not interruptions.

Some other findings:
* ChatGPT owns 68% of all AI time spent. Gemini 16%. Everyone else 16%.
* At scale, ads outscale subs. Eg Google's ad biz ($295B) is 6x the largest subscription biz.
* Google won't put ads in Gemini. A luxury only a $295B search machine can afford.
