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: 👇🏾

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

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?

Andrew Huberman shares a simple, science-backed trick to fall asleep faster when your mind races or you can't stop noticing your body position: Close your eyes and do slow, deliberate eye movements to shut down proprioception (body awareness) and signal your brain it's time to transition into sleep. Try this tonight (takes ~1–2 minutes): - Slowly move eyes left → right (a few times) - Then counterclockwise circle → clockwise circle Look up → down - Gently attempt to look toward the bridge of your nose (faux cross-eyed) - Finish with a long exhale to slow heart rate Why it works: Eye movements coordinate with your vestibular system & cerebellum to mimic the natural forgetting of body position that happens at sleep onset (similar to slow rocking or boat motion calming the brain). It gives your racing mind something active to focus on instead of "just relax." Huberman: "Many people find it helps them fall asleep quickly—it's not kooky; it's physiology." No apps, no gadgets—just your eyes. Game-changer for insomniacs or restless nights. Try it & report back.

@jonnym1ller Interested!

Is anyone open to giving me some feedback on a fun side project? The idea is to build your human operating manual (to give agents better context)

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. aboutamazon.com/news/devices/r…

@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. x.com/mehdirhasan/st…

Mehdi Hasan is evil

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

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

Idea: 1. Take a piece of well-written text 2. Ask an LLM to re-write it to make it worse using the Wikipedia article below as a guide 3. Repeat millions of times across many types of text 4. Fine tune an open source LLM to improve text by flipping the input and output of step 2

@pitdesi This is the way.

My ranking: F E (close & underrated #2) A C & D (tied) then B

@m0ldilocks @cantos @collabfund Labs!

Three years ago I got sick from something most people overlook: mold exposure. Today, that journey comes full circle: we’re announcing MoldCo’s $8M Seed (total $11M), led by @cantos + @collabfund, to build the new standard of care for mold and chronic inflammation. The mission is clear: to serve patients who’ve waited far too long for answers. To celebrate, we’re giving away 50 free lab tests. Comment “labs” to claim one and we’ll DM you!

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.”

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.

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

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

in summary: - responses = completions ++ - works in stateless & ZDR contexts - built for thinking models - unlocks higher intelligence and maximizes cache utilization in agent loops if you’re still on chat completions, consider switching now -- you are likely leaving performance and cost-savings on the table.

feeling frustrated (and a little guilty): there’s still way too much confusion about @OpenAI's Responses API. this is partly on us: we haven’t always been clear about why we built it, how to use it, and why it matters. here's my attempt at setting the record straight. 👇

No words necessary lol.

@DanielleMorrill Let’s fucking goooooo

I’m moving to SF in April

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

Amazing how much the Overton window has shifted in such a short time. For example, I remember going to a VC hosted dinner in ~2015, where guests were asked to name a recent favorite book. Fully a quarter of the table said Sapiens—unimaginable today.

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.

@LouStagner Kinda wild how many people seem to disagree with this fairly non-controversial take in my opinion. Soccer players get paid for the World Cup. Most countries pay their Olympic athletes.

When it comes to the Ryder Cup, is it OK that everyone else involved makes a profit, but the players *should* play for free? Why isn't the hot dog vendor simply honored to be selling dogs for their country and not there to turn a profit? 😃
