Validator

Stop launching businesses on a hunch. Paste this prompt into Perplexity’s Deep Research mode with your idea. Walk away for 5 minutes. Come back to a full report with real market data, named competitors, customer demand signals, and an honest GO / WAIT / NO-GO verdict — before you waste a single dollar building it.

Why I Built This (And Why You Should Use It)

I’ve started at least 7 businesses. Two are successful enough that I quit my full-time job at Meta six years ago. The other five failed — and they cost me months of my life and thousands of dollars I’ll never get back. Every one of those failures had warning signs I could have seen before I built anything, if I had spent 30 minutes doing real research. This prompt is the research I wish I’d run before each of those five.

What This Actually Does

Perplexity Deep Research runs dozens of searches across hundreds of sources and produces a comprehensive report in about 3-5 minutes. Free accounts get 5 Deep Research runs per day — more than enough to validate any idea you’re seriously considering. Output exports as a PDF you can save, share with a co-founder, or print and re-read before you commit.

Setup Run It In 60 Seconds

Step By Step

1. Go to perplexity.ai and sign in (free account is fine).

3. Copy the full prompt below. Fill in your idea details in the placeholders.
4. Paste the whole thing into Perplexity. Hit enter.
5. Walk away for 3-5 minutes — Deep Research is doing real research, not a quick search.

The Business Validator — Deep Research Prompt
You are my business idea validator. I’m about to describe an idea I’m considering building. Use Deep Research to give me an honest, data-backed assessment of whether it’s worth pursuing. Don’t flatter me. Don’t hedge. If the idea is bad, say so plainly — that’s the kindest thing you can do. ═══ MY IDEA ═══ What I want to build: [Describe the product or service in 2-3 sentences. Be specific. Not “an app for fitness” — “a subscription app that gives 1:1 video coaching to women over 40 trying to build muscle.”] Target customer (be exact): [Who specifically buys this? Demographics, role, life stage, the moment they’d need it. Avoid “everyone” or “small business owners.”] Business model: [How do I make money? Subscription? One-time purchase? Marketplace fee? Ads? Service hours?] Estimated price point: [What I’d charge. e.g. “$49/month” or “$2,500 one-time” or “15% take rate”] My background & assets: [What I bring: relevant skills, network, existing audience, capital available, time I can commit.] ═══ RESEARCH FRAMEWORK ═══ Investigate and produce a validation report covering ALL of the following. Use real, current sources. Cite everything with direct links. 1. MARKET SIZE & TRAJECTORY - Estimated total addressable market (TAM) for this category - Growth rate over the last 3 years - Whether the market is expanding, plateauing, or contracting - Major trends shaping demand in the next 24 months (regulatory, demographic, tech, cultural) 2. COMPETITIVE LANDSCAPE - 5-10 direct competitors. Name them. Link them. For each: • Pricing model • Approximate scale (revenue, users, funding stage if known) • What they do well • What they’re missing or weak at - 3-5 indirect competitors / substitutes (what customers use TODAY to solve this problem) - Whether this market is winner-take-all, oligopoly, or fragmented 3. CUSTOMER DEMAND SIGNALS - Subreddits, Facebook groups, Discord servers, forums where my target customer actually gathers (with links) - Real complaints / pain points users post about the existing solutions (quote 3-5 examples) - Search volume trends for relevant keywords (Google Trends data, comparable terms) - Whether there’s an active “we need this” voice in the market or just silence 4. PRICING & ECONOMICS - What target customers pay TODAY for the closest equivalent - Price sensitivity in this category (premium-tolerant or race-to-the-bottom?) - Typical gross margins for this kind of business - Whether my proposed price is realistic, too low, or too aggressive 5. DISTRIBUTION & GO-TO-MARKET - The 2-3 channels where competitors actually acquire customers (paid ads, SEO, partnerships, referrals, sales) - Typical CAC (customer acquisition cost) in this space - Organic / earned channels that work for this audience - Whether there’s a distribution moat — or is it open to anyone with a budget? 6. REGULATORY, LEGAL, & TECHNICAL LANDMINES - Any licenses, certifications, or compliance required (state, federal, industry-specific) - Major legal risks (IP, data privacy, content liability, regulated speech) - Technical complexity / ongoing infrastructure cost - Anything that makes this harder than it looks from the outside 7. CAPITAL REQUIRED - Realistic minimum cost to launch a v1 - Months of runway typical to first revenue in this space - Months to break-even based on comparable businesses 8. THE FOUNDER-FIT CHECK Based on what I told you about my background: - What I have that helps me win this - What I’m missing that I’d need to acquire (skill, hire, partner, capital) - Whether this is a 12-month play or a 3+ year play - One specific question I should answer honestly before committing ═══ OUTPUT FORMAT ═══ Structure the report in this order: 1. EXECUTIVE SUMMARY — one paragraph. The whole story. 2. VERDICT — one of: - GO: data supports it, real demand exists, founder-fit checks out - WAIT: market is unclear, signal is thin, or there’s a missing piece worth resolving first - NO-GO: data is against it, or the math doesn’t work With 2-3 specific reasons. 3. THE 3 BIGGEST RISKS — the things most likely to kill this 4. THE 3 BIGGEST OPPORTUNITIES — what could make this win bigger than I expect 5. THE 3 NEXT ACTIONS — specific things I should do this week (interviews to run, posts to write, prototype to build, person to call) 6. THE FULL BREAKDOWN — all 8 sections from the framework above, with sources cited ═══ HARD RULES ═══ - Be honest. If the idea is bad, say so. Don’t soften it. - If the data is thin, say so — do not fabricate market size numbers or competitor revenue - Don’t tell me what I want to hear. Tell me what’s true. - If you find something I clearly haven’t considered (a regulation, a hidden competitor, a structural problem), surface it loudly - “WAIT” is a real verdict. Sometimes the right move is to wait 6 months for a market signal to confirm. - Cite sources for every claim. If you can’t cite it, don’t claim it.
Output What You Get Back

In about 5 minutes, Perplexity returns a structured PDF report with everything you need to make a real decision instead of a hopeful guess.

01

A clear GO / WAIT / NO-GO verdict

No hedging. The first thing you read. Backed by 2-3 specific reasons rooted in the data. This is the line that saves you from spending six months on something the market won’t buy.

02

Real market data with sources

TAM estimates, growth rates, recent shifts. Not a generic “it’s a big market” — cited numbers from real reports, with the links so you can verify and re-read.

03

5-10 named direct competitors

Each with their pricing, scale, what they do well, and what they’re missing. Plus 3-5 indirect competitors — the things customers use TODAY to solve this. The substitute is usually who you’re really competing with.

04

Where your customer actually lives online

Subreddits, Facebook groups, Discord servers — with direct links. Plus real complaints they’re posting about the current options. This is where you go to validate the demand for yourself in 30 minutes.

05

The 3 next actions for this week

Specific. Not “keep researching.” The exact interviews to run, posts to write, prototypes to build, or people to call — based on whatever the verdict is.

06

A full breakdown across 8 dimensions

Market size, competitors, demand, pricing, distribution, regulatory landmines, capital required, and founder-fit. The complete dossier. Save the PDF, re-read it in 30 days, see what changed.

Decide How To Read The Verdict

The verdict isn’t the end of the conversation — it’s the start. Here’s how to act on each one:

Go

Data supports it. Real demand. You’re a fit. Move — but use the “3 next actions” section to validate one more layer before you spend money. Most GOs are still right to test before they build.

Wait

Market is unclear or you’re missing something. Don’t kill it. Don’t commit. Identify the 1-2 things that would flip it to GO — then go test those specifically. Re-run this prompt in 60-90 days.

No-Go

The hardest verdict to accept. Read the “biggest risks” section twice. If they’re structural (regulatory, market shrinking, no real demand), trust the data. Save the PDF. Move on. The next idea is coming.

One Last Thing

No prompt replaces actually talking to your customer. Use this to narrow your bets and structure your due diligence — then go have 10 conversations with real people in the target market. The combination is what saves you from the failures I’m still paying off in regret.
