Do You Have a Startup Idea Worth Pursuing?

Validation Before Vanity

You have a startup idea. Maybe it's been in your notes app for months.

The expensive mistake isn't building the wrong feature — it's pursuing a problem nobody will pay to solve for six months before you notice.

If you're still defining what a startup is, start with What Is a Startup?. If you already know the lifecycle arc, see startup stages from idea to exit. This post is the filter between "interesting thought" and your first-month roadmap.

The Three Gates

Every idea must pass three gates before it deserves full-time energy:

Gate	Question	Fail signal
Problem	Is the pain frequent and costly?	"Nice to have" in every interview
Customer	Will someone pay or switch today?	Only friends say they'd use it
Founder	Are you the right person to win this?	You hate talking to users in this market

Pass two of three with strong evidence? Keep going. Fail all three? Park the idea — no shame, just saved runway.

Problem Validation Checklist

Talk to 10 people who have the problem — not people who might someday.

• They describe the pain without you pitching
• It happened in the last 30 days
• They already spent time or money on a workaround
• The cost of inaction is obvious (lost revenue, wasted hours, compliance risk)
• Same words repeat across interviews ("spreadsheet hell," "chasing invoices")

Mom Test rule: Ask about their life, not your idea. "How do you handle X today?" beats "Would you use an app that does Y?"

Customer / Willingness-to-Pay Checklist

Engagement isn't payment. Likes aren't LOIs.

• At least 3 strangers (not your network) engaged seriously
• Someone asked when they can buy or how much it costs
• You can name a specific buyer (role, company size, budget owner)
• Existing alternatives are expensive or hated — room for a wedge
• You ran a smoke test — landing page, manual concierge, or prototype — and got opt-ins

If everyone says "cool idea" but nobody gives email, calendar time, or cash — you have a hobby topic, not a startup yet.

Market Size (Without Fantasy TAM Slides)

You don't need a $10B TAM on day one. You need a credible path to first $10k MRR.

• Beachhead segment fits in one sentence (e.g. "Turkish e-commerce shops doing €1–5M GMV")
• You can reach 100 prospects without paid ads (communities, outbound, partners)
• Expansion adjacency exists — today's niche isn't tomorrow's ceiling
• Regulation or procurement isn't a surprise brick wall

Later you'll care about unit economics and pricing — validation is narrower: can one segment love this enough to pay?

Founder Fit Checklist

Ideas aren't portable. Teams are.

• You have domain access — network, credibility, or lived pain
• You can ship an MVP in weeks, not years (skills or co-founder gap closed)
• You're willing to do unscalable work — manual onboarding, sales calls, support
• The problem stays interesting after 90 days of rejection

Solo vs co-founder is a separate decision (coming in the series) — but don't start full-time alone on a market you can't reach.

Red Flags — Stop or Pivot

Red flag	What to do
Only friends validate	Find 5 cold conversations
Solution looking for problem	Rewrite problem hypothesis
"Everyone is the customer"	Pick one beachhead
Competitor already won and you have no wedge	Niche down or new angle
You need perfect product before first user	Ship smoke test this week

Pivot isn't failure — it's cheaper than a year of building in silence.

---

7-Day Validation Sprint

Day	Action
1	Write problem hypothesis in one sentence
2–3	5 problem interviews (no pitch)
4	Synthesize patterns — what repeated?
5	Smoke test live (page, form, or manual offer)
6	5 more interviews + share smoke test
7	Score the three gates — go, pivot, or park

Output: a one-page memo — problem, segment, evidence, next experiment. That's your input for month one.
