Earlier quoted context omitted.

I love this! I keep telling my euro-friends that food and health regulation could potentially be enforced by the free market more effectively than by corruptible government, and this is a perfect example of this. I'd want to see all products I can buy in there, with all possible chemical, ingredients and nutrients, and clear indications of good/bad, a little bit like in Yuka. You should partner with them maybe even!

1. This doesn't seem to enforce anything 2. The "more free" market in the US seems to have produced worse food, based on what I am reading here I guess the words "could" and "potentially" are doing quite a bit of heavy lifting here. Either way, I agree it's a cool project! The transparency is needed, on both sides of the pond.

I agree "enforce" is a poor choice of words. It does not need to be "enforced" using state violence if any consumer can access facts with such transparency. What's missing today is this level of transparency with which the market will just naturally benefit to producer of sane and safe goods in a much more natural way.

Also, speaking of the "more free market in the US", my answer is that you don't hate capitalism, you hate crony capitalism.

Non tech, but I started a sports beverage company with my brother and a neighbor. We are based in South Florida.

My brother and I grew up playing sports and remember the simplicity of home-made drinks we'd take to games that blew the likes of Gatorade out of the park. We aim to replicate the simplicity of home-made drinks with simple ingredients.

https://www.drinkiso.com/

Our whole value-add is based around the fact that most sports drinks or hydration drinks contain a lot of junk. We are opposed to the bullshit catch-all that is "natural flavors" and believe in product transparency and honesty. Our products straddle the line between fresh-pressed juice and sports drinks. Our prices are definitely on the higher end, but with scale, we can lower them.

We currently are in growth mode - and currently are one of the best selling products in the top boutique gym chain in the Miami area, as well as going strong in all SoFLA Equinox locations (except for the WPB location which isn't open yet).

We do sell online but shipping is a PITA as overnight shipping costs for cold products are astronomical. When we find a cheaper solution so I can ship around the country, I'll let everyone here know :)

Based in South Florida (Miami-Dade, FtL, West Palm)? DM me and let's meet up!

"Google maps but for old maps": https://pastmaps.com This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS . It gets ~80K MAUs and just slowly and consistently is growing o…

That is awesome. Of course you can bolt LLMs on to any product, I'm thinking AI reviews of (historical) local businesses to give it that google maps feel.

I’ve been working on a proof-of-concept AI-powered robo advisor.

See it in action: https://youtu.be/nqZikwHkLlo

The idea is to see how far an agent can go in replicating and automating the work of a hedge fund.

The project is for educational purposes only, not for real investment.

Here’s what it currently does: - Runs a user survey to understand investment goals. - Creates a personalized strategy. - Builds a portfolio aligned with that strategy. - Analyzes the portfolio using financial APIs, tax diversification, and client alignment. - Provides a detailed portfolio analysis.

I'm launching a new product for my clock-making business: https://DigitalHorology.com None of my clocks tell the time. They're all fully automatic GPS-enabled timepieces. For a couple of years I've been developing, hand-making, and selling these clocks that track the moon phase, the sun's position, etc. My new idea is the tide clock "NautiKron." It's getting a lot of interest from US coastal buyers.

Love these! Where did you get the idea? Would love to know more.

I've been vibe coding this and that all summer. I'm making a team retro clone for sprint retrospectives, a typeform like form builder and hosting, a Reddit client with AI analysis of trends and a few other things like in various stages of development. LLMs really help me move things forward. I have those first 3 up on vercel now and I'm going to push them to production in a while after I'm satisfied with stability and the like.
