The gap
What a self-graded questionnaire cannot tell you
Self-reported answers only
You score what you write. A confident founder writes confident answers - the signal reflects your conviction more than the market's reality.
No live competitor data
The case database is historical. It will not surface the competitor that raised $10M last week or launched on Product Hunt yesterday.
No source links to verify
Per-pillar signals are derived from your text, so there is no Reddit thread, Crunchbase entry, or G2 review you can click when someone asks you to back a claim up.
30-45 minutes per idea
That designed friction is useful when you are fully committed to one direction, but it adds up fast when you are still weighing three or four options at once.
The difference
How Preuve AI adds market evidence
Live source scanning
On every run, AI agents search Crunchbase, Google Trends, Reddit, Product Hunt, G2, and the rest of 60+ live sources in real time - so the competitor that raised last week actually shows up.
Clickable source links
Every competitor entry, market estimate, and demand signal links back to its source, so you can click through and verify the claim before you cite it anywhere.
0-100 viability score
Median across 6,000+ ideas is around 55. Only 17.5% earn a go verdict. If your idea scores well against real data, it earned it.
Structured 21-section dashboard
Covers competitors, TAM/SAM/SOM, demand signals, risk flags, pivot options, and action plans. The output is structured enough to walk a co-founder or investor through without needing to narrate every number.
Workflow
How to use both without doubling your time
1
Stress-test with ReadySetLaunch
Use the 7-pillar questionnaire to write down what you actually believe about the problem, customer, and demand. The slowness forces specificity you can later check against real data.
2
Verify with Preuve AI
Take those answers to live evidence. Pull competitor maps and demand signals from 60+ real-time sources, and get a viability score with the receipts. Every claim links back to its origin.
3
Decide with both
You wrote down what you believe, then checked it against what the market actually shows. Now decide whether to build, pivot, or stop - with evidence behind each part of your pitch rather than just a gut feeling.

FAQ
Common questions about ReadySetLaunch and Preuve AI
What is ReadySetLaunch?
ReadySetLaunch (RSL) is a structured startup idea validator that walks founders through 13 questions across 7 launch-readiness pillars: Problem Intensity & Clarity, Target Customer Specificity, Demand & Behavioural Signals, Differentiation, Execution Feasibility, Distribution Readiness, and Monetisation Viability. Each answer is scored against a curated database of historical startup outcomes and returned as per-pillar signal strength rather than a numeric score. Pricing is pay-once credit packs from £14.99 with no subscription.
Is ReadySetLaunch good for startup validation?
ReadySetLaunch is good at what it claims: a structured self-interrogation across 7 pillars. The questionnaire forces founders to write out what they believe about the problem, customer, and distribution plan in plain English, which does surface gaps in weak answers. That is real value. Where it falls short is evidence: no live competitor pull, no Reddit or Product Hunt scan, no source links. RSL tests your answers about the idea. It does not test whether the market actually wants the idea.
What is the best ReadySetLaunch alternative?
Preuve AI is the best ReadySetLaunch alternative when you want source-linked market evidence on top of self-reflection. ReadySetLaunch scores your own thinking against a historical case database, while Preuve AI pulls live competitor, demand, pricing, and risk evidence from 60+ sources and links every claim back to its origin. Use RSL to find gaps in your own answers, then Preuve to find out whether the market agrees.
Does ReadySetLaunch use live market data?
No. ReadySetLaunch scores answers against a curated database of historical startup outcomes - failures, unicorn breakdowns, and acquisitions, mapped to the 7 pillars. The dataset grows through an ingestion pipeline but it is historical case analysis, not real-time market data. A competitor that launched last week will not appear. A funding round closed yesterday will not appear. For live market data you need a tool that scans the web on every run.
How is Preuve AI different from ReadySetLaunch?
They answer different questions. ReadySetLaunch surfaces gaps in how you articulate the idea. Preuve AI surfaces gaps in the market itself, through 60+ live source scans with a clickable link behind every claim. RSL outputs per-pillar signal strength scored from your text. Preuve outputs a 0-100 viability score plus a 21-section dashboard with competitor maps and demand signals. Most founders who use both run RSL first to sharpen their thinking, then Preuve to check whether the market agrees.
Should I use ReadySetLaunch or Preuve AI?
Use ReadySetLaunch if you want to slow down and challenge your own assumptions before talking to anyone. Use Preuve AI if you need clickable market evidence to take into a co-founder conversation, an investor meeting, or a build/kill decision. RSL and Preuve are complementary, not competing - one exposes gaps in how you articulate the idea, the other exposes gaps in the market. If you can only pick one, pick the one that solves the bigger problem you are dealing with right now.
Is Preuve AI a chatbot?
No. Preuve AI sends search agents to 60+ live sources in parallel, filters and verifies what they bring back, then writes a 21-section report with a clickable link behind every claim. There is no chat. No opinions pulled from training data. No "great idea, here is your 90/100." The median score is around 54 across 6,000+ ideas, and only 17.5% earn a go verdict. Preuve AI scores against external evidence; ReadySetLaunch scores against your own answers. Both will push back, just on different things.
Can I use both ReadySetLaunch and Preuve AI?
Yes. Run RSL first to interrogate your own answers across the 7 pillars, then take those answers to Preuve AI to check them against live market data. RSL costs around £14.99 for one full validation. Preuve AI is free for the initial scan and $59 for the full source-linked report. Under $80 total, and you come out the other end with both a clearer pitch and the evidence to back it up.
