$60B for a company without frontier intelligence implies serious value accrual at the context + infra layer — not just inference. same as it ever was in software
SpaceX has exercised the option to acquire @cursor_ai in an all-stock transaction with the goal of building the world’s most useful AI models. For the past few months, SpaceXAI has been jointly training a model with Cursor, which will be released in Cursor and Grok Build soon.
@adelwu_ La Rotisserie D’Argent — get the duck. Chill restaurant downstairs from the world famous Tour D’Argent. Same quality food but homier, chiller meals. Croissant at any patisserie in one of the covered passages is a super parisian experience. I like Le Valentin Jouffroy.
I'm excited to share that @getavoca has raised over $125M across Seed to Series B at a $1B valuation, backed by Kleiner Perkins, Meritech, General Catalyst, Amplify, and more to build AI agents for the services economy. Thank you to @FortuneMagazine for the exclusive cover. fortune.com/2026/04/27/avo…
@henloitsjoyce moved here 10 years ago and partially fell for this along with many other people in my cohort. based on how things turned out for all of us, it’s clear more you engage in this culture, the less likely it is that you succeed or become durably elite actually really reassuring :)
When someone dunks on your startup with an idiot hot take for clout... This is the correct reply
@wilson_spearman @ycombinator @tryunusual @KellerMaloney Moved from 70/30 stock/bond to 80/20 Alamo Square Founders Index / NVDA calls.
All marketing is psyopping to some extent, but marketing to LLMs seems to me very much a return to facts, and less vibes. Think it actually bodes well for the future. Generally it’s a bad idea to try to fool these models — they are really good at smelling marketing bullshit. The best thing to do is present them with empirical and even handed evidence that your brand can deliver on its promise for your ideal customer.
The future of marketing is psy-oping LLMs. In a few years most big purchasing decisions will be guided by AI assistants. This is scary — you have no idea what they’re saying about your product, and you have no way to change how they talk about you. We built Unusual to solve this problem. We’ve already shifted model’s perceptions of top startups from being flimsy to enterprise-ready, and have seen AI-driven leads skyrocket accordingly. Come work with us!
Congrats to @tryunusual on their $3.6M round! AI models are becoming the new influencers in buying decisions, but brands can't control what they say. Unusual is the complete AI marketing platform, helping companies understand and shape how AI talks about them.
@aditabrm @reductoai Amazing example of why specialized models are here to stay.
@aditabrm So cool. What are the sorts of tasks that are most improved by supplementing with traditional CV?
@tiwaaina @splendorhealth This is so needed.
Healthcare staff spend millions of hours each year calling insurance companies and navigating portals. @SplendorHealth automates insurance workflows (benefits verification, prior auth monitoring, credentialing) for healthcare companies, eliminating the headaches of portal access, EDI, and AI phone calls. ycombinator.com/launches/Ocr-s… Congrats on the launch, @tiwaaina!
We raised $75M in Series B funding led by @a16z, bringing our total funding to $108M. @reductoai is defining the new frontier for document intelligence, helping the world’s leading AI teams unlock data from their unstructured documents. We’re launching a new pay-as-you-go tier with 15k free credits, allowing any company to get started with Reducto. Read the full blog in the comments.
I’m thrilled to announce @reductoai’s $75M Series B led by @a16z, which brings our total funding to $108M. Just five months after our Series A, we've surpassed 1 billion pages processed and grown our monthly volume 6x. We now process hundreds of millions of pages every month for some of the world's best AI teams. Here's what we've learned and where we're headed 🧵
