I’ve met some of my favorite people at Edge Esmeralda over the last few years. Come spend a day, a week, a month with us in Healdsburg this June!

[Edge City @JoinEdgeCity]

@EdgeEsmeralda is a popup village for people who believe the future can be better and are actively working to make it happen ☀️

It is taking place May 30 - June 27, and we would love for you to join us.

Applications are open here: https://t.co/8BbJgQeoxh

Proactive prevention > reactive treatment

Just the beginning for @jwmares and @truemed to heal American healthcare

[Justin Mares @jwmares]

Today, 90%+ of healthcare spend (all $4.5T of it) goes towards treating chronic conditions after someone is sick.

Less than 3% of that spend goes towards prevention.

@Truemed exists to get more people investing in True Medicine. Exercise, food, supplements, movement, sleep, toxin removal… lifestyle interventions that help people treat and prevent disease, not just treat the symptoms of underlying sickness.

We’re building tools that allow qualified individuals to unlock the $160B in tax-free HSA/FSA funds, and use them on these root-cause interventions.

Since launching just 2.5 years ago, we’ve helped almost a million individuals pay for these interventions, and we’re just getting started.

If we want to fix healthcare in America, we fundamentally have to help Americans get healthier.

I’m extremely proud to announce our $34M Series A led by a16z, and am excited to continue our work to end the chronic disease crisis.

[Andy Bromberg @andy_bromberg]

My wife Alexa and I learned the hard way: homes can be (very) toxic. It took us a year to find & fix the cause of our health issues.

Nobody should need to go through that.

So w/ our friend @jwmares we incubated Lightwork: the world's most data-driven home health assessment.

The Meme Machine by Susan Blackmore is one of the most thought provoking books I've ever read. Now I'm investing in a different type of meme machine - @iamjasonlevin's Memelord

[Jason Levin @iamjasonlevin]

ANNOUNCEMENT:

I raised $3 million to make memes.

Yes, seriously.

Memes make millions.

[Radius Butcher & Grocery @eatRadius]

Thanksgiving pre-orders are now open! We have a wonderful menu this year featuring products from local farms with the highest integrity practices.

[Kevin Fishner @KFishner]

@W2Freedom Most local meat brands likely aren't having their processor shrink wrap the beef. It's mostly for chains that need to ship across the country / across the world

[Kevin Fishner @KFishner]

We worked on this project for several months. Time well spent to build a cleaner food system

[Seed Oil Scout📱🫡 @SeedOilScout]

The cleanest butcher in Texas tested every step of their supply chain to see where plastics are entering American beef @eatRadius

Whole Foods grass fed ribeye tested off-the-charts for toxic phthalates earlier this year, but no one could figure out where it was coming from... @natfriedman @plasticlistorg

Initial theories included:
- Plastic wrap on hay bails making it into cow feed
- Plastic cutting boards
- Butcher paper

These all turned out to be false.

Radius' levels of the main offending phthalate DEHP were 10x less than the Whole Foods average thresholds, and their in-house butcher process did not increase phthalate levels.

But why is their plastic in beef at all?

Radius' leading theory is the acidic washing and shrink-wrapping process carried out by many large US meat processors.

Meat is sprayed down with an acidic disinfectant to eliminate surface pathogens, then shrink wrapped.

The acidity breaks down the plastic, leeching into meat. Radius meat comes wrapped in loose plastic, leading to far less phthalate exposure.

Debugging our supply chains takes serious work, but the health effects of even tiny amounts of these chemicals are real.

Shout out the @eatRadius team for this study, you can read the full study at eat radius dot com slash blog 🫡

[Kevin Fishner @KFishner]

@Chris_Smeder We used Light Labs and I highly recommend!

[Kevin Fishner @KFishner]

@Chris_Smeder Oh nice I hadn’t heard of Locale but looks great! Cream Co is trustworthy. Bi-Rite sources from Stemple Creek I believe and the animal welfare is good. Plastic packaging not sure though. You can run a test for ~$500

[Kevin Fishner @KFishner]

@AustinTunnell Only if we can be homed in a beautiful masonry building!

[Kevin Fishner @KFishner]

@Chris_Smeder Thank you! I’d love to expand to SF one day but Austin and other Texas cities first. Long time horizons to build local food systems in each state :) In SF Bi-Rite has very good perishable sourcing standards in tho and i respect them a lot!

[Kevin Fishner @KFishner]

@charlescaldow I’m very curious too! This is just the beginning of our food testing research. We’ll definitely do US vs EU comparisons on both nutrient density and toxin load for various foods.

[Daryl Fairweather, PhD | Chief Economist @FairweatherPhD]

A new report from the Center for Land Economics reveals a half-billion-dollar 'error' in how the state of Maryland values land. This isn't just a local story; it's a textbook case of a market distortion that city leaders across the country should be watching closely.
The state uses a nonsensical assessment model that values land based on the building that sits (or doesn't sit) on it. This system penalizes development while rewarding speculative land hoarding. When we subsidize empty lots, we get exactly what we pay for: more empty lots.
This unfair tax system stifles the supply of new housing, drives up costs for everyone, and places a disproportionate tax burden on homeowners and active businesses.
The solution is one that economists have wanted for over a century: a Land Value Tax (LVT).
We should tax land based on its potential value, not the building on top of it. A move toward taxing land value properly would:
👉 Make it unprofitable to let valuable urban land sit vacant.
👉 Encourage the development of housing and commerce our cities need.
👉 Lower the relative tax burden on homeowners and productive businesses.
👉 Create a more fair, stable, and efficient way to fund our communities.

The land tax situation in Baltimore is a prime example of how we can improve economic prosperity across the country with a simple change based on economic principles.

“If you dream of living in a small town surrounded by creative, high-agency people, we’re building this for you,” @devonzuegel told us.

The former software engineer is building Esmeralda, a Tuscan-style town 90 mins from SF that will look and feel unlike most places built in the US over the past century.

Help us test baby formula for nutrients and toxins!

Working on a citizen science project 👀

Is there a Partiful-like platform for crowdfunding or donations?

Ideally, something more aesthetically pleasing than GoFundMe, with reasonable fees and good UX.

[Kevin Fishner @KFishner]

It’s been fun to beta interface0 - favorite power features are agent email inbox and multi-model synthesis. Ready for my inbox to become an AI command center 👏

[Andy Bromberg @andy_bromberg]

I built the LLM interface I wished existed.

interface0 is for power users: cross-provider memory & chat, multi-model synthesis, sharing & team features, granular context engineering, template prompts, forking, prompt enhancing, & more

Here's a demo—see 🧵 for the rest

[Kevin Fishner @KFishner]

@iiiitsandrea @dranthonygustin We ramp up and down the seafood case based on day of the week and shopper habit! The more people buy the more options we’ll have :) @iiiitsandrea any gulf requests??

[Kevin Fishner @KFishner]

@georgeyw_ @nickelworks @nopranablem @vijaymanohar4 you missed a good talk 😂 there will be others! also planning to public the "community capitalism" thesis

[Kevin Fishner @KFishner]

Thanks for putting on a great event @jonnyabates! I’ll publish Community Capitalism chapters starting this summer

[Jonny @jonnyabates]

@KFishner of @eatRadius spoke on Community Capitalism (Georgism 2.0), a concept that, once you grok, you can’t help apply to every discussion on land, tax, & incentives. Kevin held court for over an hour of Q&A, workshopping the many applications. Thesis coming soon...
