3 Copy-Paste AI Prompts – Pain extraction, ICP recognition, validation scoring – ready to execute with your Reddit threads
YAML Context Template – 35-variable personalization framework to tune discovery for your founder profile and problem space
Implementation Checklist – Phase-by-phase execution guide with time estimates and founder customizations
Validation Rubric – 5-signal scoring system with pass/fail thresholds to objectively kill or advance ideas
Most 0→1 founders waste 4-6 months building solutions to unvalidated problems.
They interview friends who lie. They scan social posts.
They trust gut instinct wrapped in confirmation bias.
Reddit hosts 500M+ users having brutally honest conversations about real problems. Sharing workarounds. Venting frustrations. Asking “is there a tool for X?”
89% of pre-PMF founders never mine it systematically.
The shift: AI-powered problem discovery replaces guesswork with evidence.
Extract pain signals. Identify ICP patterns. Recruit early users. Validate or kill ideas in 5-10 hours instead of 5-7 months.
This isn’t Reddit marketing. This is Reddit as a discovery engine.
System: 3-Prompt Discovery Pipeline
Three sequential prompts transform raw Reddit data into validated problem briefs.
Pain Extraction → rank 10-15 problems with user quotes
ICP Recognition → build 2-3 personas with evidence
Validation & Synthesis → score urgency, generate one-page brief
Execution: 5-7 minutes total.
Input: Reddit thread URLs.
Output: Ranked problems, ICP personas, validation scores, next steps.
Prompt 1: Pain Point Extraction
You are analyzing Reddit threads to identify recurring buyer problems for a 0→1 founder.
INPUT: [Paste 3-5 Reddit thread URLs or full thread text from r/[subreddit]]
EXTRACT AND RANK:
1. Recurring pain points — count how many times each problem appears across threads
2. Emotional intensity markers — flag words like “frustrated,” “desperate,” “blocked,” “hate,” “waste”
3. Exact user language — pull direct quotes (keep under 20 words each)
4. Current workarounds — note any hacks, scripts, manual processes mentioned
5. Jobs-to-be-done signals — what outcome is the user trying to achieve?
OUTPUT FORMAT (markdown table):
| Pain Point | Frequency | Intensity | User Quote | Current Workaround |
|------------|-----------|-----------|------------|-------------------|
| [Specific problem] | [X mentions] | [High/Med/Low] | “[direct quote]” | [What they do now] |
RANKING CRITERIA:
- Frequency: More mentions = higher rank
- Intensity: “Desperate” > “Frustrated” > “Annoyed”
- Workaround complexity: More hacks = stronger signal
Provide top 10-15 pain points, sorted by combined frequency + intensity score.Variables:
[subreddit] - Target community (e.g., r/SaaS, r/Entrepreneur, r/marketing)
[Paste thread content] - Full thread text or URLs (3-5 threads minimum for pattern detection)
Example Output:
| Pain Point | Freq | Intensity | User Quote | Workaround |
|------------|------|-----------|------------|------------|
| Can’t track content→SQL attribution | 8 | High | “Spend 6hrs/week matching URLs to CRM deals” | Manual spreadsheet + tagging |
| CMO demands content ROI proof | 6 | High | “My exec thinks content is a cost center” | Screenshot reports + guesswork |
| Multi-touch attribution guesswork | 5 | Medium | “No idea which touchpoints matter” | First-touch only (inaccurate) |
Prompt 2: ICP Pattern Recognition
You are building an ICP persona from Reddit comments showing strong pain signals.
INPUT: [Paste 5-10 Reddit comments from high-pain threads identified in Prompt 1]
IDENTIFY ICP PROFILE BY EXTRACTING:
1. Role/title indicators — job titles mentioned or contextual clues (”I report to CMO,” “I’m the only marketer”)
2. Company stage/size — team size mentions, funding stage hints, budget constraints
3. Tech stack — tools mentioned (HubSpot, Salesforce, Google Analytics)
4. Budget/resource constraints — what they can’t afford, approval processes mentioned
5. Decision-making authority — who they need approval from, stakeholders referenced
6. Geographic/timezone hints — if available
OUTPUT FORMAT:
**Persona:** [Role] at [Company Type/Stage]
**Evidence:**
- [Quote 1 with specific signal]
- [Quote 2 with specific signal]
- [Quote 3 with specific signal]
**Buying Context:**
- Budget: [Low/Medium/High based on signals]
- Authority: [Economic buyer / Influencer / End user]
- Timeline: [Urgent / Planned / Exploratory]
**Tech Environment:**
- Current tools: [List]
- Integration needs: [CRM/MAP/Analytics mentioned]
Provide 2-3 distinct personas if multiple ICP patterns emerge.Variables:
[Paste comments] - High-signal comments from Prompt 1 output (select comments with strongest pain + context)
Example Output:
**Persona:** Growth Marketer at Series A B2B SaaS (10-50 employees)
**Evidence:**
- “Our CMO wants proof that content drives pipeline before renewing budget” → reports to exec, content ROI pressure
- “We use HubSpot but can’t afford 6sense or Dreamdata” → mid-market budget, existing MAP
- “I’m the only content person on the team” → small team, wearing multiple hats
- “Need this for Q4 board meeting” → urgent timeline, Series A board pressure
**Buying Context:**
- Budget: Mid-market ($2K-10K/year for new tools)
- Authority: Influencer (needs CMO approval, budget $10K+)
- Timeline: Urgent (quarterly planning cycle, board meetings)
**Tech Environment:**
- Current tools: HubSpot (MAP), Salesforce (CRM), Google Analytics
- Integration needs: Must connect CRM + MAP, API access required
Prompt 3: Validation & Synthesis
You are scoring Reddit problem threads to validate urgency, frequency, and market opportunity.
INPUT:
- [List of 5-8 thread URLs or titles from Prompt 1]
- [Pain points from Prompt 1 output]
- [ICP personas from Prompt 2 output]
TASK 1 — SCORE EACH THREAD (1-10 scale):
- **Frequency:** How often is this problem posted? (1=rare, 10=weekly)
- **Urgency:** Is this time-sensitive or blocking work? (1=nice-to-have, 10=urgent)
- **Budget Signal:** Willingness to pay mentioned? (1=no budget talk, 10=active spend)
- **Solution Gap:** Do existing tools fail? (1=good options exist, 10=no good solutions)
OUTPUT scores as table:
| Thread | Freq | Urgency | Budget | Gap | Total | Rank |
|--------|------|---------|--------|-----|-------|------|
TASK 2 — SYNTHESIZE INTO ONE-PAGE BRIEF:
1. **Top Problem to Solve** (one sentence)
2. **Primary ICP** (one sentence with key attributes)
3. **Value Prop Hypothesis** (one sentence describing solution)
4. **Risk Flags** (2-3 potential reasons this might not work)
5. **Next 3 Validation Actions** (specific, executable steps)
Keep synthesis under 150 words total.Variables:
Thread URLs/titles, Prompt 1 output, Prompt 2 output (all feed into this synthesis prompt)
Example Output:
**VALIDATION SCORES:**
| Thread | Freq | Urgency | Budget | Gap | Total | Rank |
|--------|------|---------|--------|-----|-------|------|
| “How to track blog→SQLs?” | 9 | 8 | 7 | 8 | 32/40 | #1 |
| “Content attribution impossible” | 7 | 6 | 8 | 7 | 28/40 | #2 |
| “CMO wants content ROI data” | 8 | 7 | 6 | 6 | 27/40 | #3 |
**SYNTHESIS:**
**Top Problem:** Content marketers at Series A B2B SaaS can’t prove which blog posts drive closed deals.
**Primary ICP:** Growth Marketer, 10-50 person Series A SaaS, uses HubSpot/Salesforce, reports to ROI-focused CMO.
**Value Prop Hypothesis:** “Connect your content to closed deals in 5 minutes—no engineering, no complex attribution models.”
**Risk Flags:**
1. Market saturation — competitors like Dreamdata, HockeyStack exist (check their gaps)
2. Integration complexity — requires CRM + MAP data access (test feasibility)
3. Sales alignment — may need sales team buy-in for CRM data (political challenge)
**Next 3 Actions:**
1. DM 5 Redditors from top-scored threads (sent within past 30 days) for 15-min calls
2. Trial Dreamdata + HockeyStack to identify feature/pricing gaps
3. Post in r/SaaS: “How do you track content→revenue?” to gauge response volume
Personalization: 35-Variable Context Framework
Generic discovery misses nuances.
B2B SaaS founders need different subreddits than DevTools builders. Solo founders have different time constraints than funded teams.
Six dimensions adapt the system:
Founder Profile (role, technical depth, time availability)
ICP (target role, company stage)
Problem Space (industry, geography)
Subreddit Strategy (community size, moderation rules)
Signal Detection (pain markers, urgency indicators)
Outreach Approach (DM strategy, interview format)
Fill the YAML template. Execute prompts with context. Get ICP-tuned discovery.
Context Template
context:
founder:
role: “Technical Founder”
stage: “Pre-launch, no users”
time_available: “10-15 hours/week”
icp:
target_role: “Growth Marketer”
company_stage: “Series A”
industry: “B2B SaaS”
geo: “North America”
problem_space:
domain: “Marketing attribution”
keywords: [”content ROI”, “pipeline tracking”, “attribution”]
subreddit_strategy:
primary: [”r/marketing”, “r/SaaS”, “r/B2BMarketing”]
size_range: “50K-500K members”
signal_detection:
pain_markers: [”frustrated”, “manual”, “hours per week”]
urgency_indicators: [”board meeting”, “Q4”, “CMO wants”]
outreach:
dm_approach: “Research-framed, non-promotional”
interview_goal: “15 min problem validation”
Adaptation patterns:
Non-technical founders skip API integration questions
Solo founders prioritize fast-to-build problems
Funded teams validate TAM
DevTools founders target engineering subreddits
Consumer founders mine r/productivity, r/selfimprovement

Implementation: 3-Phase Discovery Flow
Phase 1 — Discovery (2 hours)
Run Google searches with operators: site:reddit.com “is there a tool for” [problem]
Or just search for keywords on the reddit search bar.
Identify 3-5 target subreddits.
Collect 8-12 high-signal thread URLs (rants, “alternatives to X?”, workaround posts).
Sort by “Top” (Past Month) + “Controversial”.
Phase 2 — Analysis (3 hours)
Execute Prompt 1 on threads → get ranked pain points.
Copy 5-10 high-pain comments.
Execute Prompt 2 → get ICP personas.
Execute Prompt 3 → get validation scores + synthesis.
Output: One-page problem brief with scores, personas, quotes.
Phase 3 — Recruitment (5 hours)
Identify 10-15 Reddit users from high-scored threads (posted within 30 days).
Send non-promotional DMs: “Researching [problem]—could I ask 3 questions about your workflow?”
Send 3-5 DMs/day (spam filter limit).
Book 5-10 discovery calls.
Validate or kill idea based on call patterns.
Total time: 5-10 hours from zero to validated problem brief + user interviews scheduled.
Implementation Checklist
☐ Phase 1: Search operators → 3-5 subreddits → 8-12 threads (2h)
☐ Phase 2: Run 3 prompts → problem brief (3h)
☐ Phase 3: DM 10-15 users → book 5-10 calls (5h)
Founder customizations:
Non-technical: Skip API/integration validation
Solo: Prioritize simple, fast-to-build problems
Part-time: Focus on async DMs, not live outreach
Quality: 5-Signal Validation System
Before committing months to building, validate with five reliability signals.
Signal 1 — Frequency 8+
Problem mentioned in 8+ threads across multiple subreddits.
Fail → single-subreddit outlier, not broad pain.
Signal 2 — Recency <90 days
Threads posted within 3 months.
Fail → stale problem, may be solved or irrelevant.
Signal 3 — Workaround Evidence
Users describe hacks, manual processes, time spent.
Fail → low pain intensity, “nice-to-have.”
Signal 4 — Budget Signals
Mentions of current spend, tool trials, willingness to pay.
Fail → no validated buyer behavior.
Signal 5 — ICP Consistency
3+ comments from same role/stage.
Fail → fragmented ICP, unclear buyer.
VALIDATION RUBRIC
Signal Threshold Status
Frequency 8+ ✓ 12 threads
Recency <90 days ✓ All <60 days
Workarounds Present ✓ “6hrs/week manual”
Budget Mentioned ✓ “Can’t afford X tool”
ICP Match 3+ same ✓ 8 Growth Marketers
RESULT: ✓ HIGH CONFIDENCE → Proceed to interviews

Why This Works
Customer discovery platforms exist. UserInterviews finds participants. Wynter tests messaging. G2 shows reviews.
But they require product-first or cost $500-2K/month.
Gap: No solution for pre-PMF founders to systematically discover problems + validate ICP + recruit users simultaneously from authentic buyer conversations. For free.
Reddit’s advantage:
Users admit struggles they’d never post on LinkedIn. Workaround threads reveal pain intensity. Subreddit clustering provides ICP segmentation. Ethical DMs achieve 30-50% response rates vs <2% cold LinkedIn.
Execution advantage:
AI extraction replaces 20 hours of manual reading with 5-7 minutes. Research-framed outreach, not sales. Evidence-based decisions kill bad ideas in days, not months.
