Workbook applied to a fictional consumer product. "TapNote" — voice-to-structured-notes app for iOS + Android, launched 8 months ago, 12K MAU, 1.8K paid subscribers ($7.99/mo). Question: should the next $200K of product investment go to (a) a journaling-vertical wedge, (b) a salesperson-tools wedge, (c) a podcasters wedge, or (d) just broader marketing? v2: 4-candidate narrow, 3/6/12-month horizons.
Why this example. Consumer products have a different substrate from B2B or prediction-market tooling: in-app telemetry (cohort retention, funnel), social listening (Twitter/X mentions, Reddit threads), app store reviews, customer interviews. The framework adapts — the cells stay the same, the substrate sources change. The 4-candidate narrow is harder for consumer because there are often 20+ plausible vertical wedges; v2's discipline is to drop all but 4.
Start with the 5 vertical-wedge hypotheses the team has heard from users, then expand to 25 adjacent.
5 vertical-wedge hypotheses from user interviews:
Adjacent segments (#6-#30) include: doctors (clinical notes — HIPAA risk), lawyers (privileged — work-product risk), journalists (interview capture), researchers (qualitative-coding workflows), ADHD users, language learners, etc. 4 narrowed candidates, 3 dropped.
| # | Candidate | Substrate signal (1-sentence) |
|---|---|---|
| C1 | Journaling / gratitude practice users | 22/60 interviews mention journaling. Avg D90 retention 38% (vs 22% baseline). High LTV candidate. App store reviews cite "great for journaling" 47 times. |
| C2 | Sales / SDR / real-estate agents on-the-go (CHOSEN) | 14/60 interviews, but they pay 2.3× the average ($7.99 → $18.40 pro tier). Highest willingness-to-pay. App store reviews cite "great for sales calls" 19 times. |
| C3 | Podcasters / interviewers | 9/60 interviews, niche but high NPS (67). 3 podcast hosts have mentioned TapNote on their shows. Tight-knit community. |
| C5 | ADHD / executive-function users | Adjacent but not in top-5. 6/60 interviews mention. Strong retention signal but unclear WTP. |
| Cell | C2 Sales/SDR | C1 Journaling | C3 Podcasters | C5 ADHD |
|---|---|---|---|---|
| 1. Industry | B2B sales (insurance, SaaS, real estate) | Wellness / self-improvement | Media / podcasting | Health / accessibility |
| 2. Application | Capture call notes + auto-CRMs to Salesforce/HubSpot | Daily gratitude, mood, prompt-based journaling | Interview prep, show notes, post-show recap | Voice-first task capture, low-friction notes |
| 3. End-user | Account executive / SDR (individual contributor) | Self-improvement user (consumer) | Podcaster (often solo creator) | ADHD adult (consumer) |
| 4. Benefits | Save 30 min/day on call notes; never miss an action item | Build a daily practice; mood trend visibility | Pre-interview research capture; show notes in 5 min | Capture thoughts before they vanish; low friction |
| 5. Lead Customers | Customer interviews: 14 named SDRs/AEs (Sarah K. at Outreach, Marcus P. at Ramp, 12 others) + 2 named sales coaches | 22 named journaling users | 9 named podcasters | 6 named ADHD users |
| 6. Market | ~1.5M SDRs/AEs in US | ~10M journaling-app users in US | ~150K active podcasters in US | ~10M ADHD adults in US |
| 7. Characteristics | Manager-funded; IT approval often; daily use; high WTP | Self-pay; daily/weekly use; high retention | Self-pay; weekly use; community-driven | Self-pay; daily use; price-sensitive |
| 8. Partners/Players | Salesforce, HubSpot, Outreach, Salesloft, Gong | Day One, Reflectly, Stoic | Descript, Riverside, Buzzsprout | Tiimo, Goblin Tools, Opal |

| 10. Competition | Gong + Chorus (call recording, not notes); Otter (transcription-only) | Day One (Apple-only), Reflectly, Stoic | Descript (heavy, desktop), Riverside | Apple Notes, Obsidian, Notion templates |
| 11. Platform | LinkedIn + X + sales communities (Outbound Squad, Pavilion); podcasts by sales influencers | Instagram + TikTok + journaling influencers | Podcasting communities; X #podcastlife; YouTube | Reddit r/ADHD + TikTok; accessibility communities |
| 12. Complementary Assets | Current product; team; brand among power-users; existing integrations (Notion, Readwise) | Same | Same; no audio engineering | Same; no accessibility expertise |
| Candidate | (a) similar products bought | (b) similar sales cycle | (c) word-of-mouth | Pass? | |
|---|---|---|---|---|---|
| C2 Sales/SDR | All SDRs buy Otter / Gong / Chorus / Fireflies. Substrate: 14 interviews cite "I use Otter now but it's $20/mo and I want AI structuring." | Self-serve consumer cycle (1-2 weeks). Some manager-funded (1-3 mo). Substrate: 14 interviews; 3 are manager-funded. | Sales communities (Outbound Squad, Pavilion) are tight; 1 podcast appearance by a sales influencer drives 200+ signups in a week. Substrate: 800 X mentions; 12/60 cite "found via another SDR." | ✓ PASS (cleanest pass of 4 — high WTP + clear competitive gap + 2.3× baseline pay) | |
| C1 | Journaling | Day One, Reflectly, Stoic. Substrate: 47 app store reviews cite journaling. | Self-serve (1-2 weeks). | Journaling community on Instagram + Reddit r/journaling; influencer-driven. Substrate: 60 customer interviews show 38% retention vs 22% baseline. | ✓ PASS (high retention, but lower WTP) |
| C3 | Podcasters | Descript, Riverside, Otter. Substrate: 9 interviews cite Descript + Otter. | Self-serve (1-2 weeks). | Tight-knit podcasting community; 3 shows have mentioned TapNote. Substrate: 3 podcast appearances, 67 NPS. | ✓ PASS (niche but high NPS) |
| C5 | ADHD | Apple Notes, Obsidian, Notion. Substrate: 6/60 interviews, but most use "free" tools. | Self-serve (1-2 weeks). | Reddit r/ADHD (1.4M members) is a WoM engine. Substrate: 6 interviews + 14 r/ADHD threads mention voice-to-text apps. | ✓ PASS (long-shot, lower WTP) |
Layer 1 verdict: C2 (sales) passes cleanest: high WTP (2.3× baseline), clear competitive gap (Otter is transcription-only, Gong is call recording), 14 named interviewees, 2.3× pay tier validated. C1 passes but at lower WTP. C3 passes but small market. C5 passes but price-sensitive. C2 wins on Layer 1.
| Candidate | Can we dominate in 18 months? (Y/N + why) | What would "dominate" look like? |
|---|---|---|
| C2 Sales/SDR | Y, with high confidence. 1.5M addressable market; consumer-grade product already exists; 6-mo build to ship CRM integrations + sales-team admin features; 12-mo to hit 10K paid subscribers in the vertical. | 10K paid subscribers from sales vertical ($1.8M ARR contribution from this wedge alone); 5+ named case studies from sales teams; 1 podcast-relationship with a top-3 sales influencer (Outbound Squad, Pavilion, Sales Hacker). |
| C1 | Y, but lower WTP means more volume. 50K paid users to hit same ARR. | 50K paid journaling users; 3+ influencer relationships. |
| C3 | Y, but small. 5K podcasters is the realistic ceiling. | 5K paid podcasters; show notes template marketplace. |
| C5 | Y, but price-sensitive. 20K paid ADHD users at $5/mo. | 20K paid users; 1 r/ADHD AMA; 1 publication review. |
Layer 2 verdict: C2 wins on Layer 2. 10K paid subscribers is achievable in 12 months if TC1 + TC2 land (sales-vertical case study + podcast-relationship). The 1.5M addressable market fits the 18-month window with room to spare.
| Defender | (1) Vendor-pitch rejection (0-3) | (2) "I trust X" (0-3) | (3) NPS-equivalent (0-3) | (4) Switching cost (0-3) | (5) Market-share trend (0-3) | Total / 15 | Verdict |
|---|---|---|---|---|---|---|---|
| Otter.ai | 2 | 2 | 2 | 2 | 2 | 10/15 | CAUTION — direct competitor; need clear differentiation |
| Fireflies.ai | 2 | 1 | 2 | 2 | 2 | 9/15 | CAUTION — direct competitor |
| Gong | 3 | 3 | 2 | 3 | 2 | 13/15 | UNSAFE to attack — enterprise; position alongside |
| Apple Voice Memos + Notes | 3 | 3 | 3 | 3 | 0 | 12/15 | UNSAFE — free; need a clear upgrade pitch |
| Pen + paper | 0 | 0 | 0 | 0 | 0 | 0/15 | SAFE — the "do nothing" target |
Layer 3 verdict (C2): Gong 13/15 (UNSAFE — enterprise) + Apple Voice Memos 12/15 (UNSAFE — free). Otter + Fireflies 9-10/15 (CAUTION — direct competitors). Pen+paper 0/15 (SAFE — the "do nothing" target). The HUL-Nihar reframe: TapNote's risk is not "we can't beat Gong" — it's "Apple's free Voice Memos is good enough" + "Otter is transcription-only but cheap." Substrate: 14 interviews cite "I use Otter now but I want AI structuring + CRM integration." That's the wedge.
The chosen beachhead, in one sentence:
Sales / SDR / real-estate agents on-the-go is the beachhead: 2.3× baseline WTP (substrate-validated), 14 named interviewees, clear competitive gap (Otter is transcription-only, Gong is enterprise), tight WoM via sales communities (Outbound Squad, Pavilion). C1 (journaling) and C3 (podcasters) are wedges; C5 (ADHD) is the long-shot.
The beachhead is: Sales / SDR / real-estate agents on-the-go. Layers 1, 2, 3 all pass. Layer 4 in progress. Verdict: pursue.
| # | Criterion | Threshold | Substrate |
|---|---|---|---|
| 1 | Sales-vertical paid conversions (TC1) | ≥ 4/14 from named interviews; ≥ 100 total from organic + paid | HubSpot UTM + in-app telemetry |
| 2 | Podcast appearance conversions (TC2) | ≥ 100 paid conversions in 14 days post-episode | HubSpot UTM "podcast:outbound-squad" |
| 3 | Community launch conversions (TC3) | ≥ 30 paid conversions; ≥ 5 referral payouts | HubSpot UTM + referral-bounty system |
| 4 | D90 retention by vertical | Sales-vertical D90 retention ≥ 35% (vs 22% baseline) | In-app telemetry (cohort retention) |
| 5 | MRR contribution from sales vertical | ≥ $1.5K MRR ($18K ARR run-rate) from sales-vertical in 90 days | Stripe (revenue by customer tag) |
| # | Risk (3-month) | Detection substrate | Mitigation |
|---|---|---|---|
| 1 | Salesforce/HubSpot integration breaks or lags competitor Otter | Engineering velocity; customer churn (cancel-flow survey) | If integration slips past week 4, narrow TC1 to 5 of 14 named interviewees. Pivot to a 1-way push only (no real-time sync). |
| 2 | Otter ships a CRM integration | Otter product page + Twitter monitoring | Position as "the voice-to-AI-structured-notes app" — the differentiation is structuring, not transcription. Otter is transcription-only. |
| 3 | Podcast host declines or reschedules | Direct outreach to host | If Outbound Squad declines, pivot to a smaller show (Sales Gravy, Sales Hacker) or a guest column in Pavilion. |
| 4 | Existing power-user base churns as the product becomes more sales-focused | NRR (net revenue retention) by user cohort | If NRR drops below 90%, slow the vertical pivot. The "general" voice-to-notes product is the cash engine; sales is the growth engine. |
| 5 | Sales community is closed / hostile to vendors | Outbound Squad mod response | If post is removed, the community is the wrong channel. Pivot to LinkedIn (sales leaders + influencers) + cold outbound to sales coaches. |
| # | Criterion (6-month) | Threshold | Substrate |
|---|---|---|---|
| 1 | Sales-vertical brand recognition | ≥ 3 published case studies (with named SDR/AE) | Case studies + customer interviews |
| 2 | Defender probe refinement: 5 defenders re-scored | Re-run probe with new substrate data (win/loss equivalent = cancel-flow survey) | Cancel-flow survey + customer interviews |
| 3 | Channel diversification: 3 lead sources for C2 | Podcast, sales community, inbound (each ≥ 25% of new signups) | HubSpot UTM (lead source by signup) |
| # | Criterion (12-month) | Threshold | Substrate |
|---|---|---|---|
| 1 | Revenue concentration: % from C2 | ≥ 60% of total ARR from sales-vertical | Stripe (revenue by customer tag) |
| 2 | Wedge progress: have adjacent candidates started converting? | C1 (journaling) ≥ 5K paid; C3 (podcasters) ≥ 1K paid; C5 (ADHD) ≥ 2K paid | Stripe (new customers by tag) + customer interviews |
| 3 | Defender response: have any of the 5 defenders pivoted? | Otter, Fireflies, Gong, Apple, pen-and-paper — has any moved? | Competitor product monitoring + customer interviews |
Done. The chosen beachhead for TapNote: Sales / SDR / real-estate agents on-the-go. All 4 layers pass. 3 Test Cards ready to run in the next 6 weeks. 5 success criteria + 5 risks for the 3-month checkpoint; 3 additional criteria for 6-month; 3 for 12-month. The consumer-product substrate: in-app telemetry + customer interviews + social listening + app store reviews. Different from a named-handle substrate and B2B (CRM + win/loss), but the framework cells stay the same.
