About

Startups.RIP is a research directory covering more than 1,886 Y Combinator companies, built around the idea that failed or acquired startups often contained sound ideas executed at the wrong time. The site publishes sourced reports explaining what each company did, what happened to it, and how a similar product could be rebuilt with today's technology and market conditions. It is aimed at founders and developers who want to learn from past startups rather than start from a blank page.

The service organizes its archive by YC batch and category, covering companies such as Airbnb, Chartio, Wit.ai, Triplebyte, and Truepill. Each company page can include an AI-generated research report, a practical build plan, and for paid members an implementation-oriented technical specification. A "Where Are the YC Founders Now?" section tracks founders of shut-down or acquired companies into their subsequent roles. The site is an independent project reachable via X at @oscrhong.

Key Features

Research library: Sourced reports on inactive and acquired YC companies, free to read for all completed reports in the archive.
Build plans and prototypes: Practical plans that outline how an older idea could be rebuilt today, available on both the free and Pro tiers.
Technical specs: Implementation-ready specifications, a Pro-only feature intended to take a rebuild from concept to code.
Research chat: A Pro feature that lets members ask questions about existing reports and build plans.
On-demand research: Pro members can request five new company reports per month for companies not yet covered.
Agent CLI: A command-line tool, included with Pro, that imports reports, build plans, and specs into coding agents such as Claude and Codex.
Founder tracking: A dedicated section follows where founders of shut-down or acquired YC startups went next.

Pricing & Fees

  • Pricing: A Pro plan costs $15 per month, billed annually at $180 (a 25% saving versus monthly billing); a free tier is available.
  • Free tier: Includes the full research library of completed reports plus build plans and prototypes, with email sign-up described as free with unsubscribe at any time.
  • Machine-readable access: The site publishes an llms.txt index, a sitemap, and WebMCP browser tools so AI agents can search the archive and retrieve reports in a structured way.
  • Referral credit: Builders who ship something from the research and share it publicly can earn 50% back at 1,000 organic views or a full monthly refund at 10,000, claimed by direct message.

Who It's For

Startups.RIP suits aspiring founders searching for a validated idea with documented history, indie developers who want a technical starting point rather than market research alone, and product managers or analysts studying why startups pivot or shut down. It is also useful for writers and researchers tracing what happened to specific YC companies or where their founders landed afterward. Developers working with coding agents like Claude or Codex benefit most from the Pro tier's CLI and technical specs.
