our take on why @saranormous' is probably the most important framing on what to work on, and what matters.

We're excited about the US CLARITY Act.
We think all YC companies will use crypto technology, like stablecoins, before long. Not just crypto startups, not just fintech startups, but every company.
Here's why this law is such a big deal 🧵
https://x.com/SenLummis/status/2063768467145105813
Senator Cynthia Lummis: The Clarity Act passed committee. The floor is next. We did not come this far to quit at the 5 yard line.

Re @garrytan @connorking @NousResearch This is the EXACT stack that I covered in yesterday's 1 hour workshop. https://www.youtube.com/watch?v=yzlvDnxvi1I + @youdotcom

Very pleased to hear Anthropic have walked back this policy https://simonwillison.net/2026/Jun/11/anthropic-walks-back-policy/
SemiAnalysis: BREAKING NEWS: Anthropic's latest model will NOT help you if it thinks your ML research/ML engineering is interesting, and/or will secretly degrade its IQ so that the average engineer won't notice. We are already seeing Anthropic's latest model's moderation filters our GPU

We’re rolling out changes to make Fable 5’s safeguards for frontier LLM development visible.
Starting this week, flagged requests will visibly fall back to Opus 4.8—the same as our safeguards for cyber and bio. You will see this every time it happens. On the API, any flagged requests will return a reason for their refusal (coming to server-side fallback in the next few days).
We wanted to deploy Fable 5 to our users quickly and safely. Visible safeguards can be probed, so they have to be robust, which takes time to get right. Invisible safeguards can be targeted more narrowly, allowing us to ship quickly with very few false positives. We went with invisible safeguards for this reason—and that was the wrong tradeoff. You should have visibility into the safeguards we have in place, and why. We’re sorry for not getting the balance right.
Making the safeguards visible makes them easier to work around, so keeping them robust to jailbreaks will unfortunately mean more false positives while we improve the classifiers. We're also tuning our bio and cyber classifiers to trigger less often on harmless requests. We know this is frustrating and we’ll do our best to keep this period as short as possible.
If you think a request has been mistakenly flagged: run /feedback in Claude Code, click thumbs-down on the fallback in http://Claude.ai or Cowork, or file the safeguard appeal form for API requests. Your reports help us tune these classifiers and we appreciate your feedback.

Subscription plans are massively subsidized.
And by massively, I mean absurdly:
Claude Max 20x: $200/month, with usage reportedly worth around $8,000
ChatGPT Pro 20x: $200/month, with usage reportedly worth around $14,000
SemiAnalysis: Recently, we purchased one of each Anthropic/OpenAI subscription plan and randomly ran long horizon coding tasks until we exhausted the weekly limit. It's widely believed that a $200/month plan maxes out at ~$2000/month worth of tokens (assuming API pricing). However, we found

Amazing project. We need this now more than ever.

I talked to a founder today whose customers are all really nice people, because their initial market happens to be one that attracts such people. The founders themselves are nice for the same reason. They're enjoying starting a startup as much as any founders I've known.

Jackie Fielder boycotted Dreamforce and attacked Salesforce CEO Marc Benioff as “incredibly dangerous.”
Dreamforce brings real jobs and money to San Francisco. She chose to grandstand against a major local employer instead of fighting for the people in her district who are struggling with potholes, dirty streets, and open drug markets.
This is not leadership. This is turning her back on San Francisco workers to score political points.
Jackie Fielder must resign.

This past March, @CarinaLHong sat down with @latentspacepod for an episode on the Series A announcement.
"Verified AI sounds like eating broccoli and paying taxes, but to Axiom it's about scaling brilliance, compounding brilliance."
Agentic superintelligence needs Verified AI.

Exceptional model. Go try it today.

Gigs (YC W21) has spent years quietly rebuilding the telecom carrier stack as software. Now they can partner with any company that wants to offer phone plans to their customers, like Block. It's a gigantic market, expect to hear a lot about them from here.

Today we're launching Kapa for Agents: all your product knowledge, in one tool call.
As models get smarter ... and pricier ... (looking at you Claude Fable), context is becoming the bottleneck. Here's why:
Say you've built an agent in your SaaS app with some tools. Then a user asks "How do I enable SSO?" but you haven't given the agent a tool to fix that. It doesn't matter how smart your agent is, it hits a dead end.
Instead, with Kapa, you can add easily add a single knowledge search tool so your agent can read your docs, code, tickets.
Real-world agents use this in +40% of interactions to improve planning and avoid dead ends.
TL;DR: we spent 3 years building the best agentic retrieval platform that:
→ Finds the right source ~2x more often than web search or a DIY RAG pipeline
→ Tells you what your agent couldn't answer, and exactly how to close the gap
→ Connects 30+ sources in one click, synced in real time so knowledge doesn't go stale
→ Works with any agent: product copilot, support agent, or Claude Code
Teams like @tweetsbyport, @airbytehq, @circleci and @matillion are already using Kapa's Retrieval MCP and API to build in-product copilots, support agents, RFP tools and coding assistants.
... and today, its available to everyone at kapa [.] ai / agents.

AI is now doing our AI research.
At Recursive we set out to build recursive self-improving superintelligence (RSI) to automate knowledge discovery. The best way to expand humanity’s knowledge is through the scientific method.
RSI leads to better ideas, explanations and inventions which lead to better RSI. Automating the scientific method requires closing the loop between ideation, implementation and validation, and being able to run it over extended periods of time.
Today, we are excited to share the first outputs of Recursive’s automated open-ended discovery system. To be clear, this system is merely a milestone towards RSI, a v0.1 of what I sometimes call the “Eureka Machine”. It is one program that you can point at any hard problem and get useful inventions out. Though it’s still very early, we've run it on three AI tasks and achieved state-of-the-art results on all three.
These results demonstrate that even this early version of the system can solve a variety of autoresearch problems in AI and improve over prior state of the art. Concretely, it did this on the community benchmarks NanoGPT speedrun, NanoChat, and NVIDIA's Sol-ExecBench.
AI is code and AI can code.
The code and ideas that lead to these results were not invented by our team but by the AI system itself.
To do RSI safely, we need to investigate its inventions. That's best done transparently with the community.
@Recursive_SI we are open-sourcing the system’s discoveries, demonstrating that it finds creative and benign solutions instead of focusing on obvious optimizations or dangerous ideas.

YC has changed my life twice: first as a founder, and now as someone who gets to back and support ambitious talent that's unproven
feel lucky to do this work, and even luckier to do it with people I admire so much
Y Combinator: We're excited to announce Diana Hu (@sdianahu) as YC's newest Managing Partner.
Diana co-founded Escher Reality (YC S17), which was acquired by Niantic, where she shipped AR to the 100M+ people playing Pokémon GO. Since returning to YC as a partner, she has worked with nearly

Together with UC Berkeley we are announcing the laser phase plate - a breakthrough in atomic resolution imaging. This is the brightest continuous wave laser in the world, 100 million times the intensity of the surface of the sun.
Phase contrast plays an important role in microscopy, but it was thought close to impossible for electron microscopy, where it would require interfering with an electron beam. Holger Mueller and Robert Glaeser proposed exactly this using a standing wave laser. It has taken over 15 years to make this a reality. Biohub partnered with UC Berkeley and Mueller to support this work and to engineer and build the technology.
Contrast has been the critical barrier to achieving atomic resolution imaging of the cell. In cryo-electron tomography, a cellular imaging technology that uses electron microscopy, the low contrast makes it impossible to resolve anything but the largest proteins within their cellular context. The laser phase plate removes that barrier.
With advances in AI this breakthrough in contrast will start to open up a new frontier in structural biology, that will allow us to see the molecular machines of the cell, and how they assemble into far more complex and dynamic systems, and understand how they work.

I once had to kick a founder out of YC for lying. Thankfully we caught them before the batch started.
Today I found out they're running a European startup accelerator 🤷‍♂️

Awesome takedown video. Suspects assault and rob the victims, and then @SFPD uses @Flock_Safety ALPR + drones to locate and arrest them.
This tech is helping thousands of agencies, every day, keep Americans safe.

AI agents are powerful, but they don’t remember your preferences.
So you end up repeating instructions- How you structure projects. Your brand guidelines.
You can now teach Replit Agent your conventions with Custom Instructions and Skills.
It'll take them into account for every project automatically.

I am teaching a few dozen parents and their kids how to set up Hermes this Sunday in SF with @Alphaschool.
1. Are these the right topics to cover? Anything I'm missing? Maybe use it to build a quick website, app, or game?
2. What's the easiest way to hook Hermes up to Google Workspace? I'm not sure I want to show these kids Google Cloud console.
I will probably teach the same session to everyone on YouTube later so no need to feel fomo.

We went from 0 to 2,200 paying customers in under a year by following @ycombinator's 15 rules:
1/ Do things that don't scale. Get your first 10 customers by hand.
2/ Launch now, not when it's "ready". A mediocre product in front of real users teaches you more in a week than 6 months of polishing in the dark.
3/ Charge from day one. If nobody will pay, you don't have a startup, you have a hobby.
4/ Talk to users every single day. The roadmap you need is sitting in your customers' heads, and they'll hand it to you for free
5/ Always hunt the 90/10 solution. For almost any feature there's a way to capture 90% of the value with 10% of the effort.
6/ There are only two real jobs: write code and talk to users. Everything else (conferences, press, VC coffees, corp dev calls) is fake work.
7/ You pick your customers as much as they pick you. 10 users who love you beat 1,000 who kind of like you.
8/ Growth is an output, not a strategy. Grow before product market fit and all you're buying is churn.
9/ Do less, really well. Pick one or two metrics and judge every task against them.
10/ Know if you're default alive. Paul Graham's question: on current growth and current burn, do you reach profitability before the money runs out?
11/ Don't hire until it hurts. Headcount is not progress, it's burn. Every great startup was embarrassingly small for embarrassingly long.
12/ Momentum is the only real moat in year one. Ship something every week, even something tiny.
13/ Every great startup is badly broken at some point. The game isn't avoiding fires, it's how fast you put them out. Again. And again
14/ Ignore your competitors. Startups die of suicide, not murder. In year one, the only company that can kill yours is your own
15/ Startups rarely die from running out of money. They die because the founders fall out. Brutal honesty with your cofounder is the cheapest insurance you'll ever buy
Good luck !

I built Branda 100% with @Replit ✨
500 users have tried it.
Pretty crazy that anyone with a good idea and with some motivation can build something that would have cost $100k+ just 6 months ago.
I spent about 1 month building this and total costs were under $3,000.
Was it easy? No. Lots of learning, experimenting and connecting all the dots but Replit made it a whole lot easier.
Basically, it wouldn't not have been possible without it.
There's lot of things happening under the @brandacooks hood, dozens of actions, APIs, processes to bring you the best logo/branding possible. Still applying refinements!
Much more coming in the future!
Branda: Meet Branda v1✨🎉
http://Branda.co — An entirely new fun way to create and manage brands!
We built Branda because we saw the gap between what AI is capable of and how practical it is for users to extract tangible brand value from it.
Today we solved that gap. 🧵

"The Regents vote went completely contradictory to the faculty recommendation to retain the SAT...what I keep hearing from people is your faculty want this. 1400, 1600, whatever. And the January 2020 report that unanimously recommended retaining standardized testing from the faculty, which the Board of Regents then unanimously voted against." -- President Milliken (just now in a meeting of the Assembly of the Academic Senate)
O.M.G.

One of the worst takes in tech right now is not hiring new grads.
At Replit, we're arbitraging an industry mistake.
We doubled our new grad hiring targets and they're onboarding now.

A founder asked me how to build an AI-services business without it turning into a consultancy. My answer: the whole game is in how you charge.

Re The pricing model determines what you build. Charge for outcomes and you're forced to invest in software that compounds. Charge for time and you never will. Pricing isn't downstream of the product. It IS the product decision.
