Markets matter more than ideas. This skill helps you evaluate whether your market is worth entering — and how to validate demand before you build.
Markets matter more than ideas. This skill helps you evaluate whether your market is worth entering — and how to validate demand before you build.
Before doing market sizing, validate that real people have this problem.
Method 1: Cold Outreach (Fastest — 1-2 weeks)
Cold outreach template:
Subject: Quick question about [problem area]
Hi [Name],
I'm researching how [ICP role] handles [specific problem]. I noticed you [signal that they have this problem — e.g., posted about it, work in relevant role, use a competing tool].
Would you be open to a 15-minute call this week? I'm not selling anything — just trying to understand the problem better before I build a solution.
Happy to share what I learn from the research as a thank you.
[Your name]
Method 2: Communities (Higher quality — 2-4 weeks)
Method 3: Landing Page Test (Lowest effort — 2-3 weeks)
Decision threshold:
5 conversations reveal 80% of what you need to know. The other 20% you learn by building and shipping. Don't wait for certainty — it never comes.
Tell AI:
Help me size the market for my SaaS idea:
- Product: [what it does]
- Target customer: [who — job title, company size, industry]
- Problem it solves: [the pain point]
Do a bottom-up calculation:
1. Estimate how many potential buyers exist (use industry data, LinkedIn job title counts)
2. Multiply by a realistic price point for this type of tool
3. Apply a 1-3% capture rate for a new entrant
4. Tell me: does this math support a solo-founder business ($200K-500K ARR)?
1. How many potential buyers exist?
[Industry size] × [% that match your ICP]
Example: 500,000 US marketing agencies × 12% that are 5-20 person = 60,000
2. What will each pay annually?
[Price point] × [12 months]
Example: $49/month × 12 = $588/year
3. Realistic addressable market:
[Buyers] × [Annual price] × [Capture rate]
Example: 60,000 × $588 × 2% = $705,600/year achievable
4. Sanity check: Does that number fund the business you want?
Solo founder needs $200K-$500K ARR to replace income + reinvest.
If max realistic capture is $100K, the market is too small.
TAM = Total market revenue (all possible buyers globally)
SAM = Segment you can serve (geography, vertical, size)
SOM = What you can realistically capture in 3 years
Rule of thumb: SOM is 1-5% of SAM for a new entrant.
If SOM doesn't fund your business, stop here.
Tell AI:
Analyze the competitive landscape for my product:
- My product: [what it does]
- My target customer: [who]
- Known competitors: [list any you know, or "not sure"]
For each competitor, find: pricing, target audience, strengths, weaknesses
(check G2/Capterra reviews for complaints). Then build a 2x2 positioning
matrix showing where I could differentiate.
Every product competes with four types:
For each direct competitor:
## [Competitor Name]
**What they do**: One sentence.
**Target audience**: Who they sell to.
**Pricing**: Tiers and price points.
**Strengths**: 2-3 things they do well.
**Weaknesses**: 2-3 gaps, complaints, or underserved areas.
**Positioning**: Homepage headline — how they describe themselves.
**Traffic/Scale**: Monthly visits (SimilarWeb), review count (G2/Capterra).
### Where You Win
What specific thing will you do 10x better?
Build a 2×2 matrix with the two dimensions your ICP cares most about:
Example axes:
X: Simple ←————→ Powerful
Y: Cheap ←————→ Premium
Plot competitors on this grid. Find the empty quadrant. That's your positioning opportunity.
Score each criterion 1-5. Minimum viable total: 25/40.
| Criterion | Score | Notes |
|---|---|---|
| Pain intensity — Hair-on-fire problem? | /5 | 5 = actively searching for a fix |
| Willingness to pay — Already pay for substitutes? | /5 | 5 = pay $50+/mo for something worse |
| Reachable audience — Can you find and contact them? | /5 | 5 = concentrated in known communities |
| Fragmented competition — No dominant monopoly? | /5 | 5 = many small players, no clear winner |
| Small enough for solo — Can one person serve this? | /5 | 5 = low support burden, self-serve viable |
| Recurring need — Will they use it monthly? | /5 | 5 = daily/weekly active use |
| Your unfair advantage — Domain expertise or distribution? | /5 | 5 = deep insider knowledge |
| Technical feasibility — Build core in 4-8 weeks? | /5 | 5 = well-understood, no R&D needed |
Scoring:
| Channel | Cost to Test | Time to Signal | Scalable? |
|---|---|---|---|
| Cold outreach | $0 (time only) | 2-4 weeks | Somewhat |
| Communities | $0 (time only) | 1-3 months | Somewhat |
| Paid search | $200-500 | 1-2 weeks | Yes (if CAC works) |
| SEO / Content | $0 (time only) | 3-6 months | Yes |
| Directories | $0-200 | 1-2 months | Yes (passive) |
| Partnerships | $0 (time only) | 2-6 months | Yes |
Rule: Pick the ONE channel you can test in <30 days with <$500. Prove it works before diversifying.
Confirm your ICP can actually buy:
All five should be "yes" for a solo-founder SaaS.
| Mistake | Fix |
|---|---|
| Analysis paralysis — researching for months instead of shipping | 5 conversations + napkin math. Then build. |
| Inflating TAM to feel good ("it's a $10B market!") | Bottom-up only. TAM is a vanity metric for solo founders. |
| Ignoring "do nothing" as a competitor | Most of your market tolerates the pain. Your real competition is inertia. |
| Researching the wrong ICP | Talk to the person who writes the check, not the person who has the problem. |
| Only talking to people who confirm your idea | Seek disconfirming evidence. Ask "why wouldn't you use this?" |
| Skipping competitive pricing research | Visit every competitor's pricing page. Screenshot them. This is your anchor. |
