Sensitivity
| 2% monthly churn | 3% monthly churn | 4% monthly churn | 5% monthly churn | 6% monthly churn | |
|---|---|---|---|---|---|
| $25 CAC | 8.2 | 5.8 | 4.6 | 3.8 | 3.2 |
| $35 CAC (central) | 11.5 | 8.1 | 6.4 | 5.3 | 4.5 |
| $50 CAC | 16.4 | 11.6 | 9.2 | 7.6 | 6.4 |
| $70 CAC | 23.0 | 16.2 | 12.9 | 10.6 | 9.0 |
Methodology
Payback = CAC / monthly contribution margin. Central case: CAC = $35 (decision.metrics target marketing spend per subscription acquisition, paid search + DACVB-referral blend); monthly churn 4% (typical pet-subscription range 2-8%); ARPU = $9.99/mo; subscription COGS = $1.50/mo (API + storage + CDN) so monthly contribution = $8.49 per subscriber. Row spread: -40% / baseline / +40% / +100% CAC. Column spread: 2-6% monthly churn (industry range). Each cell = months until cumulative subscriber LTV exceeds acquisition cost.
Monthly Cashflow Strip
| Month | Operators | MRR | Burn | Cash |
|---|---|---|---|---|
| M1 | — | $0 | $22,000 | $193,000 |
| M3 | — | $800 | $22,800 | $147,400 |
| M6 | — | $3,500 | $21,400 | $87,100 |
| M9 | — | $9,200 | $18,500 | $31,600 |
| M12 | — | $18,200 | $11,900 | $0 (bridge / production financing needed) |
| M15 | — | $37,400 | -$6,600 | post-positive cashflow |
| M18 | — | $56,000 | -$17,800 | BREAKEVEN + path to profitability |
M1-M3: Phase 2 engineering ramp - opex ~$22-24K/month (HW + FW contractors, SAB retainer, ops overhead). M4-M9: Phase 3 tooling + concierge MVP - opex ~$24-27K/month (mold deposits staged, FCC submission, concierge supervision, insurance bind, early component buys). M10-M12: Phase 4 launch ramp - production starts, opex 2%/month growth for support + marketing. M13-M18: scale - units shipped grow from 100/mo (M12) to 300+/mo (M18); subscription attach drives recurring revenue. Revenue blend: hardware $249 avg M SKU + subscription ARPU $9.99/mo. COGS: hardware $26.05 BOM @10K + assembly $11.45/unit = $37.50 COGS @10K (higher at @1K early run); subscription COGS $1.50/mo. Quarterly OTA cadence, SAB protocol review gate at M9, FCC clearance by M9. Breakeven M18: revenue $56K > opex $32K + COGS $6.8K = ~$17K operating profit. Post-breakeven 85% hardware GM + 80% subscription GM funds opex growth and accumulates net profit. Modeled
Risk Register
Risk register
| Risk | Severity | Likelihood | Mitigation | Confidence |
|---|---|---|---|---|
| On-device dog-pose inference (MobileNet v3 on ESP32-S3) may not generalize across dog breeds, sizes, coat colors, and lighting conditions; accuracy > 92% required for reliable calm-state detection | High | Medium | Collect diverse training data in Phase 1 beta (all sizes, breeds, lighting, home environments); validate >= 92% top-1 accuracy and >= 95% calm-state precision on held-out test set before FCC submission; implement cloud Gemini Vision fallback for borderline cases when local confidence < 0.7 | Modeled |
| MEMS microphone array directional storm detection may have high false-positive rate (vacuum cleaner, TV dialogue, traffic can trigger 80 Hz detection); false sessions waste treats and degrade the protocol | Medium | Medium | Implement 3-second confirmation window (require 3+ successive 80 Hz pulses before triggering session); tune FFT parameters in Phase 1 beta across real homes; allow manual disable/override during high-noise household activity | Modeled |
| Injection-mold tooling lead time (8-12 weeks for Shenzhen partner) is the dominant critical path; any delay pushes launch from Month 18 to Month 24+ | High | Medium | Identify Shenzhen mold partner by Phase 2 Month 2; lock lead-time commitment in writing; stage 30% tooling deposit on Phase 3 go-signal; arrange express-freight reserve ($5K) if needed | Sourced |
| Behavioral-claim defensibility (DACVB SAB protocol sign-off) gates the regulatory positioning (training aid vs medical device); weak SAB commitment opens FTC scrutiny on therapy claims | High | Low | Engage DACVBs at Phase 2 kickoff (not Phase 3); require published track record on desensitization protocols; lock 1-year retainer ($12K); maintain written protocol review documentation and a claims audit trail | Sourced |
| WiFi + Bluetooth stack stability on ESP32-S3 during high-CPU inference load; background storm detection must stay on while inference runs at 5 fps | Medium | Low | Leverage dual-core ESP32-S3 (core 0 WiFi/BT stack, core 1 inference); implement brownout detection + graceful fallback to local-only session logging; load-test WiFi stability under inference load in Phase 2 | Modeled |
| Supply-chain disruption (MEMS PDM mics, ESP32-S3) could delay component availability for first 1K-unit run; 8-12-week lead times on critical components | Medium | Low | Lock long-lead components (ICS-40180, ESP32-S3-WROOM-1) by Phase 3 Month 1; negotiate 6-month supply agreement with distributors; identify alternative mics (ICS-43432) and SoCs (nRF5340) for fallback | Assumption |
| Iatrogenic safety event - a calm-state misclassification delivers a treat during fear; one viral failure thread on r/dogs collapses brand positioning | Critical | Low | Calm-state precision target 95% (conservative threshold 0.7); behavioral firmware refuses dispense during anxiety classification even on manual trigger; cloud-side rate limiter (1 dispense / 20 s, 30 / session); SAB-monitored field telemetry with immediate OTA dispense-halt on any verified event; insurance recall reserve | Modeled |
