Is That Startup Idea Already Dead? ‘Build or Skip’ Checks Competitors’ Survivability

Founders exploring a new idea often ask a deceptively simple question: “Has anyone tried this before — and are they still alive?” A new web service called Build or Skip aims to answer exactly that, by scanning historical launch data and checking whether those products are still up and running.

The site continuously crawls public directories such as Y Combinator’s startup list and Product Hunt launch pages. For each product, it inspects the official website and records whether it’s active, parked, or showing a shutdown or error page. In its October 30, 2026 snapshot, for example, Build or Skip notes that a project once launched on Product Hunt as Early Stage Founders Playbook now resolves to a parked domain, signaling that the original product is effectively defunct.

Users can search by name or keyword to see which similar products have launched before, how many are still operating, and when others appear to have gone dormant. The idea is to turn “competitor graveyard analysis” into a quick lookup instead of hours of manual Googling. For teams in Japan, tools like this could slot into early‑stage market research: checking foreign precedents, spotting patterns in what failed, and using that context to refine positioning before committing serious time and budget to a new SaaS or consumer app.
