How a Vibecoded Newsletter Is Making the Hay Market More Transparent

AI-Generated Summary

A young founder named Aiden Johnson has built Haywire, a newsletter that brings transparency to the opaque hay market by aggregating and simplifying public data from the USDA and regional auction houses. What started as a casual question from his dad—"What’s the price of hay?"—turned into a real-time intelligence platform that helps farmers, brokers, and horse owners make better decisions in a market where prices vary wildly by region and quality. The episode reveals how AI and 'vibe coding' now enable two college students to automate data collection, analysis, and distribution in ways that would have been impossible just a decade ago. Beyond the novelty, Haywire exposes a deeper truth: many commodity markets remain fragmented and under-served by data infrastructure, creating massive opportunities for entrepreneurs who can turn public, buried data into actionable insights. The story isn’t just about hay—it’s a blueprint for how AI is democratizing access to market intelligence, one niche at a time.

Key Takeaways
1

Use AI to automate data aggregation from public sources like USDA reports and auction house feeds to build a real-time intelligence layer in opaque markets.

2

A niche market like hay—despite being essential—lacks a standardized benchmark, creating a massive opportunity for data transparency.

3

The middleman in commodity markets (like hay brokers) stand to lose from increased transparency, as their margins rely on information asymmetry.

4

AI-powered 'vibe coding' allows two young founders to build a scalable, automated data business with minimal infrastructure.

5

High hay prices are driving second-order effects: horse boarding costs are rising, sanctuaries are at risk, and dairies are mixing high- and low-quality hay to control costs.

The Birth of Haywire

I've always thought that one way you could build a business as a young journalist or someone is find... Find a piece of public data that exists, that is out there, that is consumable for free, that nobody is regularly looking at. Gather it, become the central repository for it and then occasionally comment on it.

But yeah, I've been talking to a lot of horse owners and they're basically saying we love our horse so much but the return on investment on horses right now is just like it's too expensive.
