Both ship. Cursor wins on tight editor UX, tab-completion, and inline diff review — it's the fastest daily driver if you live in the IDE. Claude Code wins on longer autonomous tasks: it will actually plan, run commands, and finish a multi-file refactor without babysitting. Rule of thumb: Cursor for edits you'd otherwise type, Claude Code for tasks you'd otherwise assign to a junior. Most teams end up running both.

Buy the domain the day you have a name you'd still like in six weeks — not before. A parked .com costs less than a rebrand, but hoarding domains you never ship is a tax on your focus. If the name only works with a stretched TLD (.ai, .io, .dev), that's fine — Google doesn't penalise TLDs. If the exact-match .com is >$5k, ship on the .io and revisit after PMF.

Yes. YC reads late applications and admits from them every batch. The bar is clarity, not polish: a 60-second video where you and your cofounder explain the problem in your own words beats a slick deck. Ship a working demo (even a rankraw sandbox iframe counts) before you write the app — every question is easier to answer when the product exists.

As of mid-2026, the shortlist is Lovable, Bolt.new, Replit Agent, and v0. Lovable leads for full-stack apps with a real backend; Bolt is fastest for landing pages and prototypes; Replit Agent wins when you need to keep a long-running dev environment; v0 stays best for isolated UI components. Rank them by whether they can hand you a Postgres row and a deploy URL without leaving the chat.

In order of frequency: (1) the hero doesn't say what the product does in under three seconds; (2) the CTA asks for signup before showing the product; (3) there's no proof — no logo wall, no screenshot, no live embed; (4) the pricing page is behind a demo call; (5) the meta description is still the template default. Fix in that order — the first two account for most of the drop-off.

Wispr started as a wearable and pivoted to a dictation app when they noticed users wanted to speak-to-text everywhere on their existing devices, not on a new one. The lesson: your PMF signal is usually a smaller, sharper wedge inside the vision — the fastest teams cut scope until the wedge fits in one sentence and one download.

Yes — it's rare but it happens. Founders who returned usually did three things: shipped something demonstrably new during the gap, kept the partners updated without asking for anything, and applied to the next batch with a cleaner story about what changed. YC's bet is on the founder, not the pitch, so the recovery arc matters more than the setback.
