AI in Agriculture: What Works and Who Wins

AI in agriculture is one of the few AI markets where you can check the claims. Camera-based precision spraying has been sold commercially since 2021, universities have run field trials on it, and the numbers are public. They show a real prize and a specific disappointment: the same machine cut herbicide use by 90.6 percent in one field and 43.9 percent in another. That variance is the product problem, and it is the part a founder should build against.

AI for Small Business: What to Automate First

Most advice about AI for small business is a list of tools, which is the least useful part. What an owner needs is an order: which job goes to an agent first, which one stays human for now, and what breaks when you move too fast. Siddhi Mittal, co-founder of the private chef marketplace yhangry, gave a short talk at Y Combinator's Root Access about going all in on agents across engineering, product, and growth. Her sequence is copyable by any small business, and the part that broke is the most useful part of it.

Latent Demand: What It Is and How to Find It

Latent demand is usually taught as a market gap: a want the market has not met yet. That definition is true but not actionable, because it does not tell you where to look. Boris Cherny, who created Claude Code at Anthropic, has an operational version he calls the single biggest idea in product: people will only do a thing they already do, so find the thing they are doing by hand and make it easier. CLAUDE.md and plan mode both came out of that rule. Here is what latent demand is, how it differs from stated and effective demand, and how to run the rule on your own product.

Vertical SaaS: The Legora $100M ARR Playbook

Vertical SaaS used to be the conservative choice: smaller market, lower ceiling. AI inverted that. When the cost of building generic software collapses, the part that does not collapse is knowing exactly how one industry works and having permission to touch its data. Legora went from $1M to $100M in ARR in 18 months selling into law firms, one of the least fashionable buyers in software. Here is the business model underneath that run: why bundling beat the point solutions, what actually defends a vertical against a foundation model lab, why one workflow travels across countries, and where the model still breaks.

Physical AI: What It Means for Founders

Robotics spent a decade as the field where nothing generalized. Then it started copying the language-model playbook: pretrain on the world, fine-tune on actions, let reinforcement learning close the gap. Nvidia's Jim Fan calls it the great parallel, and it changes what a founder is actually looking at. Here is what physical AI means in practice, why the constraint moved from models to data, what breaks when software can act on atoms, and the vertical playbook a small team can run without owning a fab.

AI for Supply Chain: The Founder Opportunity

A single advanced AI chip crosses a dozen countries and takes months to build, and the people responsible for it are working from spreadsheets, SAP, and phone calls. Y Combinator put out a call for founders to build supply chain 2.0 for chips, and the reason it is a startup rather than a feature is specific: the buyer's real pain lives in the second and third supplier tiers, where the incumbent system of record has no data at all. Here is what AI for supply chain actually has to do, why the bottleneck moved to packaging and memory while the tooling stayed still, and the test for whether your version is a company.
