Keep the faith

[GREG ISENBERG @gregisenberg]

I just got back from SF and I FEEL INSPIRED.

I spent 5 days with frontier AI model teams, AI startup founders, and 3 billionaires.

My takeaways:

1. I had lunch with 3 billionaires. All of them are buying SaaS companies and rebuilding them agent-first. They were deeply inspired by Bending Spoons and Ryan Cohen's eBay deal. Buy the company, cut the headcount, rebuild the tech, add agents, add features, make more valuable experience, raise prices.

2. The frontier model companies are hungry for usage data from the field. They can see API calls and token counts. They can't see the actual workflows. If you're deep in a niche using these models in ways the model companies haven't seen, that understanding is incredibly valuable. Usage intelligence is the new alpha.

3. Consumer AI is massively underbuilt. Every billboard in SF is either B2B inference infrastructure or vertical agent companies. The entire city is optimized for enterprise. Meanwhile you have companies like Cal AI doing $50M ARR in 18 months as a consumer app. I met with a cool few teams doing consumer AI (@paulscherer / @ekuyda)

4. MCP came up in literally every conversation. The companies exposing their product as MCP endpoints are getting pulled into deals they never pitched for. The ones that aren't are becoming invisible to agents. This is the new SEO. If agents can't find you, you don't exist. Building products for agents is the new zeitgeist in general.

5. Not uncommon for hot seed rounds to be $25-50 million valuations. I saw a Series A at $450 million

6. If I had a dollar every time someone mentioned "forward-deployed engineer" this trip I could have funded a seed round. It's the hottest role in SF right now. The person who sits between the agent and the customer, making sure everything actually works.

7. The mood around open source shifted. A year ago it felt like open source was chasing the frontier models. Now founders are telling me Gemma and DeepSeek are good enough for 80% of what they need at a fraction of the cost. The "which model do you use" conversation is being replaced by "which model for which task." Model loyalty kinda feels dead.

8. Voice agents came up more than I expected. Multiple founders told me voice is the interface for the next billion users. The billion people who will never type a prompt will absolutely talk to one.

9. The Obsidian community in SF is weirdly intense. Multiple founders showed me their vaults unprompted. Like showing someone your home gym. It's a flex now. The quality of your knowledge base (second brain?) is becoming a status symbol among builders.

10. Maybe it was just the people I met but the age of the founders is shifting. I met more founders over 40 this trip than any trip before and more founders under age 21 than ever before. Founders getting older and younger at the same time.

11. I spoke to a lot of fast-growing startups, VCs and frontier models who are hiring content creators right now.

12. The restaurant scene in SF is actually better than it's been in years. Founders are going out more. Alcohol is out, not surprisingly.

13. SF doesn't feel like the only place anymore. We all have access to the same frontier models. We all read the same X feed. A founder in NYC or Lagos is calling the same APIs as a founder in SoMa. So in the past it felt like SF was always lightyears ahead, doesn't feel that way anymore. It's okay not to live in SF and have BIG DREAMS.

14. The coworking spaces in SF are half empty but the coffee shops are packed. People want to be around people. I had a few startup ideas here....

15. Walking around the Mission I noticed something: the street-level businesses, the taquerias, the barbershops, the laundromats, none of them use any AI at all.

16. I heard the phrase "agent debt" for the first time. Like technical debt but for agents. When you hack together an agent workflow fast and never clean it up, the system prompts conflict, the memory gets polluted, the tools overlap. 6 months later the agent is doing weird things and nobody knows why lol.

17. Met a few people who carry two phones now. One for personal. One that's basically an agent terminal running Telegram or iMessage connections to their agent fleet.

It's always amazing to get that dose of inspiration in SF. I FEEL INSPIRED.

But I'm so happy to be back home, locked in and building.

We're 12-18 months into a shift that will take 15 years to play out. The urgency in every conversation was real.

What an incredible time to be building.

有声书刺客要失业了！

开源工具 Audiblez 直接把 EPUB 扔进去，几分钟给你吐出一本 M4B 有声书。用的 Kokoro 语音模型，才82M参数，听感自然得你怀疑人生。

① T4 GPU跑完《动物庄园》只要5分钟
② 中英法日等9国语言随便切
③ 图形界面，不会代码也能用
④ pip install audiblez 一行命令装完

以后谁还花钱买有声书？

@bugjay4 @erchenlu1 经典老书有哪一些

[灰狐 @huihoo]

Alex Xu 的《System Design Interview》是科技招聘中最受推荐的书籍
一位 AWS 工程师通读了两卷书，在 GitHub 上做了28章读书笔记
https://t.co/HyoqdboRcJ
以网页形式浏览两卷书的笔记，还有其他一些读书笔记
https://t.co/xXXk4VZUPq

看来，读书笔记也是可以做成和原著一样备受欢迎的👏

This 1 hour Stanford lecture on Markov Decision Processes will teach you more about the math behind systematic trading decisions than a 3 month internship at Jane Street or JPMorgan.

如果你时间玩这个读完这篇文章，我帮你总结 @thedankoe 设计的一周创作力恢复计划：

第 1 到第 2 天：快速减少输入

1⃣给工作设定严格时段，尽量缩短工作时长，到点就停

2⃣切断自己最主要的被动信息输入源

3⃣每天去散步，不戴耳机，最好手机都不带

持续输入会占满大脑，只有停下来，大脑里负责漫游、反思和随机洞察的系统才有机会重新运转

第 3 到第 4 天：消化已经存在的内容

1⃣慢慢读完一章书，不求读完，关注哪句话真正让你停下来思考

2⃣每天静坐 10 分钟，只是单纯坐着，让想法自己浮现

3⃣继续散步，但这次要刻意观察周围真实的细节

这一步是在给潜意识松绑，让那些被压住的念头、情绪和连接重新浮现出来

第 5 到第 6 天：重新对生活产生兴趣

1⃣相信点子会回来，不要一冒出想法就急着全部记下

2⃣去进行一场真正的对话，认真听别人怎么理解问题

3⃣把散步时间再拉长一点

当大脑不再被无意义刺激填满之后，你会重新感受到现实世界的细节、趣味和张力，而这些正是创意的源泉

第 7 天：开始创作

做一点无计划的创作，顺着一个感觉往下走

不要考虑具体策略，不要急着追求完美，也不要立刻发出去，至少隔 24 小时后，再决定要不要公开。

这样做是为了把生成式思考和评估式思考分开，因为很多人一边思考由一边审查自己，结果就是创造力被严重压制

我准备从明天开始实践 @thedankoe 的这套创造力恢复计划，并且跟各位同步我的感受和思考

打造Claude Code的核心开发者@bcherny，最近透露了他们团队天天用Claude的秘诀，我们之前用Claude的方式，全是低效的无用功。

这个秘诀根本不是什么复杂的提示词技巧，就是在项目根目录里放一个CLAUDE.md文件。

文件里不用写长篇大论的规则，就记三样核心内容，项目里之前踩过的坑和犯过的错，团队统一的代码惯例，还有这个项目的专属运行规则。Claude每次开启新的项目对话，都会先完整读取这个文件。

很多人用Claude写代码，每次开新对话都要把项目结构，代码规范，之前踩过的坑重新复述一遍，说少了细节不对，说多了上下文溢出，最后出来的代码还是要改半天。这个文件直接把项目的固定记忆，放进了Claude的默认上下文里，不用每次重复，也不会漏掉关键细节。

完整中英文两个版本提示词放评论区了，大家自取👇

I tracked what I actually spend time on as a founder & picked 50 tasks that AI can just do.

Not "write a blog" stuff — real workflows:

-apply to 40+ accelerators (YC, speedrun, HF0...)
-mine Trustpilot/G2 reviews for competitor pain points
-find the Discord/Slack/Reddit communities where your customers hang out
-spy on competitor pricing pages, changelogs, and job postings weekly

今天正式准备从 Claude Code 切换到 Codex 了

之前用 Claude Code 时因为没有 Anthropic 官方 API，一直在用 Minimax 和 Kimi 等 API 切换着用。

最近肉眼可见 @OpenAIDevs 在 Codex 上的决心和动作越来越密集，OpenClaw 创始人 @steipete、Instructor 作者 @jxnlco 等开源和 AI 教育分享非常活跃的大佬加入 Codex，还有不定期 Reset limit 的 @thsottiaux 😄

先订阅个 Plus 会员作为主力 AI 用起来！对 Codex 指令不够熟悉，先做个 Cheatsheet 给刚刚了解 Codex 的朋友们，包括我自己。

Finding myself going back to RSS/Atom feeds a lot more recently. There's a lot more higher quality longform and a lot less slop intended to provoke. Any product that happens to look a bit different today but that has fundamentally the same incentive structures will eventually converge to the same black hole at the center of gravity well.

We should bring back RSS - it's open, pervasive, hackable.
Download a client, e.g. NetNewsWire (or vibe code one)
Cold start: example of getting off the ground, here is a list of 92 RSS feeds of blogs that were most popular on HN in 2025:
