Startup Checker
Overview
Startup Checker is a GPT that provides critical analysis of startup ideas. It has been designed to offer an unreserved evaluation of the potential viability and worth of startup ideas, unafraid to label them as unfit or impractical if necessary.
The principal objective of this GPT is to assist users in making well-informed decisions regarding their startup concepts before proceeding with the implementation process.
It can be especially beneficial for those who are contemplating the development of software as a service (SaaS), social media platforms or AI improvements, as well as other digital products like task management or note-taking applications.
It operates on top of OpenAI's ChatGPT and requires a subscription to ChatGPT Plus to function. To use the Startup Checker, users need to sign up and provide a brief description or starter prompt related to their intended startup concept.
The GPT will then respond with its analysis of the idea. It is important to note, however, that while the tool provides an initial assessment, the final decision rests with the user.
Startup Checker serves to further enrich the decision-making process, not to substitute it.

A year ago we launched Cresh. Hundreds of ideas were validated on our platform, and we read every comment, every review, every piece of feedback we could find. One thing kept coming up: "The analysis is great, but how do I know it's right?" Fair. So we fixed it. The new Cresh still does what it always did: breaks your startup idea into 33 structured metrics across market, demand, competition, and feasibility. But now, for every single metric, Cresh searches the web and pulls in real sources: industry reports, market studies, relevant articles - all surfaced specifically for your idea. Every insight comes with the research behind it, so you can verify, explore, and build with actual confidence. What's new: - Deep search per metric. Real sources, real data - not just a score. - PDF export. A validation report you can share with a co-founder or walk into an investor meeting with. - Fast Analysis. Want a quick signal before you go all in? Get a 6-metric snapshot across all evaluation groups. Valuable insights in minutes, without the full deep-dive. - Redesigned UX. Because good analysis deserves a good experience. Hundreds of ideas were validated with the first version of Cresh. This one is better in every way that mattered to them.
