I’m thrilled to announce Heyday’s $6.5M Seed led by @kevinthau @sparkcapital

We were fortunate to close our round before the market got crazy.

We’re sharing our fundraising process to help founders who are still in the thick of it.

Our process: 👇🏾

[Nathan Baschez @nbaschez]

Introducing Roughdraft!

A new open source project designed to make collaboration with agents better.

The idea is to bring commenting and suggested changes to markdown (e.g. plan docs) in a nice interface.

Free, local, etc.

Love the management principles shared by @andysparks here but love the design even more!

[Andy Sparks @andysparks]

Excited about a new thing: I built a management library you can talk to. 5+ years of coaching founders, noticed they all run into the same stuff. I kept using the same frameworks. So I turned them into cards you can read in five minutes or paste into an LLM that helps you actually implement them.

@newstart_2024 @grok for this, when attempting to look toward the bridge of my nose, should I still have my eyes closed?

@jonnym1ller Interested!

People ask me all the time about compelling use cases of AI. Here’s a good one.

Millions of dogs go missing in the U.S. every year—and options for finding them are often painfully limited. Our Ring team saw an opportunity to use our community and technology to help, so they built Search Party.

When a pet owner posts about a lost dog in the Ring app, nearby participating outdoor Ring cameras in the neighborhood begin looking for potential matches. If yours spots what might be the missing dog, it lets you know. You see the photo alongside footage from your camera, then can choose to share the video with the pet’s owner.

The AI is trained on tens of thousands of dog videos so it can recognize different breeds, sizes, fur patterns, body features, unique marks, shape, and color. And privacy stays in your control—you decide each time whether to help.

The impact is energizing. Search Party has helped bring home 99 dogs in just 90 days—more than a dog a day since launching three months ago.

Ring customer Kylee was blown away by Search Party after her dog Nyx was found by a neighbor’s camera just 15 minutes after slipping through a tiny hole he’d dug under her backyard fence.

When a Ring customer and military veteran named Kurt realized his service dog was missing after jumping his fence, he worried he might have lost her for good. He quickly initiated a Search Party in the Ring app asking neighbors to help locate her. Later that day, he got the notification he was hoping for…Lainey was found.

Chris, a Ring camera owner, helped reunite another lost dog with its family after getting an app alert that said, “Your camera may have spotted a missing dog,” flagging footage he wouldn't have otherwise noticed.

And the list of stories like these keeps growing.

Now we’ve expanded this feature so that anyone in the U.S. can start a Search Party through the Ring app, even without a Ring camera (lost pets are one of the most common posts in the Ring Neighbors app—over 1M last year alone).

With roughly 90 million dogs in the U.S., think this is gonna matter for a lot of families. Good example of real-world impact, and proud of what the Ring team has built here. https://t.co/Pr3jzP4o4o

It's going to be tough for startups when all the Lord of the Rings names are taken and the only thing left is something like Bombadil AI.

@elonmusk @elonmusk do you think you’re the only one who’s allowed to make shitty jokes? I don’t think that makes you evil and I don’t think that makes Mehdi evil either.

[Mehdi Hasan @mehdirhasan]

I deleted this sarcastic quote-tweet because MAGA and Islamophobic folks are clipping it out of context and trying to ridiculously suggest I’m inciting violence. I was obviously mocking the MAGA slogan ‘Make America… Again’ slogan and highlighting the shocking number of plane crashes under Trump and the FAA cuts. But this tweet was in poor taste, poorly worded, and has allowed people in bad faith to call me a terrorist, with one New York Post reporter cc-ing the FBI. So I deleted it.
Meanwhile, the right wants to silence all journalists while crying ‘free speech!’

[Samiur Rahman @Samiur]

@nbaschez At the very least, its data for better reinforcement learning with good and bad examples.

[Samiur Rahman @Samiur]

@nbaschez Actually, this is a legit good idea, and I think it would work really well.

[Samiur Rahman @Samiur]

@pitdesi This is the way.

Ezra Klein on Charlie Kirk:

“You can dislike much of what Kirk believed and the following statement is still true: Kirk was practicing politics in exactly the right way. He was showing up to campuses and talking with anyone who would talk to him. He was one of the era’s most effective practitioners of persuasion. When the left thought its hold on the hearts and minds of college students was nearly absolute, Kirk showed up again and again to break it. Slowly, then all at once, he did. College-age voters shifted sharply right in the 2024 election.

“That was not all Kirk’s doing, but he was central in laying the groundwork for it. I did not know Kirk and I am not the right person to eulogize him. But I envied what he built. A taste for disagreement is a virtue in a democracy. Liberalism could use more of his moxie and fearlessness. In the inaugural episode of his podcast, Gov. Gavin Newsom of California hosted Kirk, admitting that his son was a huge fan. What a testament to Kirk’s project.”

“Kirk and I were on different sides of most political arguments. We were on the same side on the continued possibility of American politics. It is supposed to be an argument, not a war; it is supposed to be won with words, not ended through bullets. I wanted Kirk to be safe for his sake, but I also wanted him to be safe for mine, and for the sake of our larger shared project. The same is true for Shapiro, for Hoffman, for Hortman, for Thompson, for Trump, for Pelosi, for Whitmer. We are all safe, or none of us are.”

[Packy McCormick @packyM]

I’ve been scrolling too much since Charlie Kirk’s shooting yesterday, and there is much, much more agreement - that this was a heinous crime, that debate is good, that it’s tragic a family lost its dad - than disagreement.

Don’t let the loud minority of crazies (and bots) win.

[Samiur Rahman @Samiur]

Uh, idk what’s going on in our simulation but I just vehemently agreed with Rand Paul of all people.

[Rand Paul @RandPaul]

JD “I don’t give a shit” Vance says killing people he accuses of a crime is the “highest and best use of the military.”

Did he ever read To Kill a Mockingbird?

Did he ever wonder what might happen if the accused were immediately executed without trial or representation??

What a despicable and thoughtless sentiment it is to glorify killing someone without a trial.

[Samiur Rahman @Samiur]

@prashantmital I don’t think the Responses API allows for structured, JSON schema responses, does it?

[Samiur Rahman @Samiur]

No words necessary lol.

[Samiur Rahman @Samiur]

@DanielleMorrill Let’s fucking goooooo

[Samiur Rahman @Samiur]

@nbaschez Most annoying thing is most VCs don’t read any fiction or sci-fi, and they’re supposed help imagine the future lol.

[Samiur Rahman @Samiur]

100% agreed. It may be tough, but it’s worth trying to understand people you disagree with. And don’t let it ruin your existing relationships.

[Paul Graham @paulg]

Don't do this. No matter how much you dislike Trump, don't do this. Half the people in America voted for Trump. If you think voting for Trump makes people evil, then you have to believe half the people in America are evil, and that's just deluded.
