The best moment in history to build a company.

Every so often, technology rewrites the rules of what one person can build. It happened with the internet, it happened with mobile, and it is happening now with artificial intelligence — only this time the change runs deeper: it doesn't make a channel cheaper, it makes building the company itself cheaper.

Three data points say it better than any argument.

Less capital than ever

Y Combinator's Winter 2025 batch was the fastest-growing in the accelerator's history: 10% a week, as a group. And it did it with less capital than any batch before it. The marginal cost of building a product, testing it in the market and scaling it has collapsed — what used to take a Series A is done today with a fraction of a pre-seed.

Fewer people than ever

In a quarter of that same batch, 95% of the code was written by AI. Agents no longer assist with tasks: they replace entire workflows — development, customer support, marketing, operations. A team of 3 with the right stack does today the work that three years ago took 30.

More scale than ever

Andreessen Horowitz describes it as a platform shift on the scale of the internet: companies will grow in value faster than we have ever seen. When the cost of serving each additional customer tends to zero and the product improves on its own with every interaction, the scale curve stops looking like anything that came before.

The conclusion is simple: it has never been so possible to build a great company with so little. The window is now — and the companies that capture it will be the ones born AI-native, not the ones that adapt later.

That is exactly what we do at Fundadores.net: found, from day zero, the AI-native companies that seize this window.
