"Our goal is for people to never have to deal with their health insurance again": 73% of Americans say delays and denials of medical treatment by healthcare insurers are a major problem.

Now, a company called Sheer Health says they will fight insurance battles on behalf of their clients. https://t.co/CUKSHbN9PH

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

Yet another study showing similar muscle growth when using heavy vs light loads. The evidence is overwhelming on the topic: loading ranges of ~5 to 30 reps build muscle equally. Very nice study design from the lab of @mackinprof 💪 https://t.co/Z9g7oWsOqS

New York City continues to be one of the healthiest places in the USA. Latest life expectancy data shows national avergae = 79.3 years. But 2025 NYC = 82.6 years.
That's a big jump from the peak of COVID, when it fell to 78 yrs.

last newsletter was sponsored by @sheer_health but it seemed interesting as a user so I decided to check them out (they did not pay for this post lol)

basically you log into your health insurers portal via their app and they look through all your claims to see if you were over billed, see what benefits you haven’t used, deal with appeals, help you pick a plan, etc. They discovered my eye exam probably overbilled me!

also interesting pricing model - it’s either free and you give 10% of whatever money they save you or pay $40 a month and pass you all the savings).

A lot of companies have tried this and eventually pivoted into the employer space, but I'm hoping we have a consumer-focused one because that feels like it can actually help a lot of people.

At the very least I'm now just going to point people to this when they ask me questions about their bill.
