We built the thing everyone knows should exist but doesn’t.
Tens of millions of people are turning to AI for health questions. Not because they think AI is smarter than a doctor—because it's a place they finally feel heard. It’s available 24/7, never rushed, and speaks plain language. But those conversations lack context and often go nowhere. They’re not connected to health history or to actual care. General Medicine is changing that. Today we’re sharing a new way to connect feeling heard to getting care. We automatically gather your health history in one place where you can discuss with an AI chat that’s designed by our doctors to help summarize your health and figure out what should come next. You can schedule exactly the care you need directly from your chat and your General Medicine doctor will review everything in advance. At your visit, they know exactly where to start. You’ve almost certainly never seen your health story like this before. Try it, ask questions, get care you might be putting off, and share your feedback: Generalmedicine.co/ai

Every digital artifact can be expressed as code and code gen is coming to every digital product. Preston and Eitan are building lightning fast models and infra for devs implementing coding agents. Privileged to work with this supremely talented team alongside friends at a16z!
.@relace_ai has raised $23M to build the rails for AI code generation. This round is led by @a16z, with participation from @matrixvc and @ycombinator. LLMs have proven they can write code—but scaling that code into production still needs better infrastructure. Relace is building exactly that: the infra layer where models and systems are co-optimized for code generation. We’ve already shipped: - The fastest apply model on OpenRouter (10k tok/s) - State-of-the-art code reranking and embeddings models These models have already processed tens of millions of requests from customers like Lovable, Magic Patterns, and Orchids. Now, we’re taking it a step further: with Relace Repos, we’re working on a new source control system that’s built for the age of AI-generated code, with native retrieval and deep integration into our models. If you're looking to build code generation into your product, please reach out!

Agentic interfaces really need domain specific primitives and integrations to reliably nail outcomes for non-technical users and go beyond demoware. We're going to see AI-first startups slogging to backfill those as aggressive pre-AI mid stage companies layer AI interfaces on top of years of deep engagement with customers. Parabola is a perfect example of the latter and their new AI phase is here!

Most software has evolved. You describe what you want, and it just works. But despite the promise of AI, operations teams have been totally left behind. Still exporting csv files, cleaning data by hand, and getting stuck running the same agonizingly manual workflows over and over. We built the new @tryparabola for them. Now, turning operational expertise into automated workflows is as simple as describing what you want.

JJ and I met at FB. When he sold his first startup, we had a conversation about money that I’ve had with dozens of acquired founders. It goes something like: “No, the wealth managers don’t have any big secrets. Just buy indices and chill.” JJ’s second startup turns that notion into a product for everyone: customizable index investing, tax loss harvesting, and – importantly – no fees! Excited to be involved as both investor and customer.

Congrats to Mevo on their $19M Series B, led by @tjparker. Mevo is tackling a huge opportunity in Brazil: digitizing prescriptions where paper was the norm. With 10M patients using Mevo this year alone, they're well on their way to transforming pharmacy for 150M Brazilians.  Read more: endpts.com/former-amazon-pha…

Excited to back Pedro and the team at Mevo -- leading e-prescription vendor and consumer healthcare marketplace in Brazil. The end-state cx for pharmacy in most countries will look a lot like this. And Mevo is the farthest along I've seen, anywhere. endpts.com/former-amazon-pha…
