I only spent part of the second day at vibecon @Replit. I think, I got the much needed inspiration from these two presenters before leaving.
The drive back to CT was crazy. Police cars all along the FDR with their lights flashing. I think I attribute it to the Knicks parade.

A bit of déjà vu at @ycombinator Demo Day earlier this week. (sharing in case you're curious)
Webflow went through YC back in 2013. A lot of people have been asking: why do YC again with @ployai? A few reasons ...

Bryant Chou (@bryantchou) co-founded Webflow, which today powers around 1% of all websites on the internet.
Now he's back in the current YC batch with @ployai, an AI-powered website and marketing platform that doesn't just build your site — it connects to your analytics, CRM, and search console to optimize your marketing while you sleep.
In this episode of the @LightconePod, he explains how he built Ploy to be “anti slop,” how building today compares to his first startup, and why founders with domain expertise are making a comeback.

medium was burning $2.6M a month when they replaced the phrase "free and open" from the company's rules with "a safe, respectful, and welcoming environment." then came substack. the untold story of what should have been the next great publishing giant from @HarrisSockel
Pirate Wires: Publishing platform Medium raised over $157 million, at one point burning over $2.6 million per month, in an effort to become something like the “Netflix of publishing” — the default destination for the best writing on the internet, all for $5/month.

We are so confident that @photoroom_ML has the highest product fidelity in the world for images that we guarantee it. Fidelity or token refunded.
Just walked off the Black Stage at VivaTech with an announcement I’ve wanted to make for a long time.
Photoroom now comes with a product fidelity guarantee: if our AI ever changes your actual product , your logo, your colors, the details that matter, you get your token back.
In ecommerce, fidelity isn’t optional. The customer has to receive exactly what they saw. What you see is what you get.
It only works because of two models behind the scenes, our foundation model research PRX Pixel , and a visual quality model that catches any drift before an image ships.
Also great to catch up on research with our long time advisors thanks to @ylecun and @julien_c . 🙏

Garry 说了一句所有 founder 都该刻进脑子里里的话，但 99% 的人可能只读到了表面那层，把坏消息放董事会第一页，远不止是大家说的诚实美德，
多数人只会把Garry 这条建议当成励志鸡汤，其实它本质是一套主动设计的强制纠错机制，
把你最害怕给董事会看的东西，强制做成 slide one——这不是在讲透明，核心是说怎么把董事会从评审团转变成利益共同体，
他专门用括号加了一句最关键的话：you can only do this with good boards btw，
这句话才是整个建议的引擎，
因为绝大多数董事会，你说实话他们会惩罚你，你敢把最坏的东西放在第一页，他们会觉得你有问题
但好董事会看到你把伤口先亮出来，反应是：行，我们一起缝
这才是 slide one 规则真正的前提，不是勇气，是你在跟谁开会
然后我去翻了 Garry 引用那个案例，Mutiny 的 CEO Jaleh Rezaei 干了一件更极端的事
她之前的公司 Mutiny 做到 8 位数收入，客户是 Snowflake 和 Uber，销售 AI SaaS，听起来已经赢了
但她把客户解雇了，把团队砍了，把公司围绕 AI agent 重新创立
倒不是看到趋势转型，关键是要在船还没漏水的时候主动凿沉，
背后有一个数字让她做了这个判断：销售人员实际用于销售的时间，只占 21%
如果 AI agent 把这 21% 吃掉，整个销售 SaaS 的逻辑地基就裂了
我以前有个做投资的兄弟跟我说过一个比喻，好的董事会和坏的董事会的区别就像开刀
坏的董事会看到你肚子疼，让你多喝水别耽误干活，把疼藏住
好的董事会看到你掀开衣服指着一个地方说这里最疼，第一反应是：手术台在哪
Garry Tan 这条建议的本质，就是在筛选谁值得跟你一起上手术台
把最害怕的东西做成 slide one 然后把它当成大事来庆祝——前面那个动作是信任，后面那个动作是习惯，两个加起来才成立
Garry Tan: Tip: pick the worst thing you are afraid to show your board for your next board meeting and make it slide one (you can only do this with good boards btw)
Make it a big deal you did that. Make it a habit.
