Practical thinking on product decisions, evidence, and delivery.https://heyargus.app/https://heyargus.app/blog/yc-cursor-for-product-management/https://heyargus.app/blog/yc-cursor-for-product-management/YC's Spring 2026 Request for Startups named this category directly. Here's what that says about the size of the gap — and why it's opening now.Sat, 05 Sep 2026 17:42:02 GMThttps://heyargus.app/blog/why-every-prd-starts-from-a-blank-page/https://heyargus.app/blog/why-every-prd-starts-from-a-blank-page/The reasoning behind last quarter's decisions lives in someone's head, or a stale doc nobody reopens.
