Premortem

Gary Klein's premortem: assume we already failed, then explain why. Written from the future so the team treats these as facts to prevent, not abstractions to debate.

Premortem · written from the future
It's May 2028. Babelio is dead. Here's why.

We died of three things, in order. First, the wedge was too small and we were in the wrong mode. We chased immersion learners who wanted cheap subtitles with original audio preserved — they never paid for the dub minutes our margin depended on, and our $6–12 WTP ceiling sat below the prosumer COGS floor. Second, the moat was a head start, not a moat (0/7 Helmer). The audio tap was public CoreAudio/WASAPI plumbing; a funded competitor cloned it in a quarter, and we never instrumented the per-app telemetry flywheel that was our only durable asset. Third, the platforms swallowed us. Zoom, Teams and Meet kept extending native translation; install friction and a Gatekeeper-flagged binary made our consumer download a hard sell against "already built in, free." We ran out of cash before the B2B/SDK pivot got traction.

How to use this page Each premortem cause maps to a numbered risk below. Score = a 1–9 grid (probability L/M/H × impact L/M/H, L=1 M=2 H=3, multiplied). Anything ≥7 is reviewed weekly at the leadership sync (13-operating-cadence.html); a fired tripwire pages the owner same-day.

Top 10 risks

Ranked by score. The first three are the premortem causes and the review's fatal-risk trio (skeptic premortem: wedge 45% / moat 30% / install 20%). Owner abbreviations: CEO founder, AE audio/OS engineer, GL growth lead, CEO+L founder with outside counsel.

P0 / P1 from the review

Lifted verbatim-in-substance from REVIEW.md §3–4 (synthesis of 4 independent reviews). P0 = fix before shipping; P1 = fix before next iteration. Each maps to a risk above. The COGS-contradiction P0 is shown resolved (tech.md §8 adopted as source of truth) — it is the one P0 already closed.

P0ICP / mode / beachhead collision audience.md §1,§3 · maps to R1

Triple contradiction: primary ICP (immersion learners) wants original audio preserved and structurally avoids paid dub minutes; market/growth name interpreters as beachhead (declared Anti-ICP); the hero auto-mute+dub is anti-product for the stated ICP. Action: pick ONE primary ICP org-wide; if learners, make subtitle/dual-track the default and monetize subtitle minutes + Anki-export.

P0Zero user validation; WTP ceiling below COGS floor audience.md whole-doc · maps to R1, R4

Entire customer model is desk-derived — one [PAST] datum, zero completed interviews, zero LOI/prepay. Validated WTP ceiling ($6–12/mo) sits below the COGS-driven prosumer floor ($30–80/mo) — resolved by assertion, not a test. Action: run the Week-1 Mom-Test plan (15–20 learners, verbatim script, <30% kill-criterion) + Van Westendorp + Week-2 metered $5/hr concierge on 30–50 buyers before locking tiers.

P0Founder-market fit completely absent BRIEF.md team · maps to R5 · human input

No founder section, no audio/OS-internals proof, no distribution audience. The whole moat depends on one rare hire (Rust + CoreAudio/WASAPI). If solo non-technical, the 10-week MVP and the moat are fiction; VC scores Team 0/50. Action (not auto-patchable): record founder technical background in BRIEF.md and confirm the OS-internals engineer is committed before any MVP timeline is trusted.

P0COGS contradicted 5–13× — resolved monetization §4 · tech §8 adopted

Dub COGS spanned $0.50 → $2.97 → $12.5/hr across three docs; the whole "must self-host TTS or die" thesis rested on the unverified figure. Resolved: tech.md §8 adopted as single source of truth — Cartesia Sonic + Deepgram, 55% duty → ~$0.50 dub / ~$0.31 subtitle per active-hr. Self-host TTS downgraded to a Growth-stage option (see R10, now low-score). De-risk by shipping a working Cartesia dub at ≤$0.50/active-hr before raising.

P1"Tap IS the moat" contradicts own 0/7 Helmer score ai-thesis §4 · maps to R2

Audio tap uses public CoreAudio/WASAPI APIs; ai-thesis itself scores Process Power ✗ and 0/7 powers secured. It is a head-start, not a moat. The only real moat candidate — the per-app capture/eval telemetry flywheel — is "not yet being collected." Action: reframe the tap as a head-start; make the telemetry flywheel a day-1 instrumented requirement.

CORROBORATED: skeptic (self-confirmed by ai-thesis.md)
P1Growth loop asserted but product is single-player / non-viral growth.md §3 · maps to R9

North Star = private sessions dubbed; the live case is ephemeral and single-player; export is a review artifact, not viral; re-publishing dubbed copyrighted streams is barred (legal-ops §4). The loop drives the entire $15–40 CAC vs $230 paid CAC — and may not exist. Action: design a legally-clean shareable artifact (bilingual clips of the user's OWN content), instrument the share/activation event, OR demote the loop and budget real paid/community CAC, then re-run LTV:CAC.

P1Headline price mismatch breaks TAM · LTV conflates NRR with retention market §3 · monetization §4 · maps to R4

Three price anchors ($12 TAM / $15 Pro / $12 WTP cap). Separately, LTV used NRR (95%) in the lifetime multiplier (×20), ignoring 6–8%/mo logo churn — true LTV ≈ $112, LTV:CAC ≈ 3.2:1, not 5.7:1. Action: align all three docs on one ARPU; recompute LTV = ARPU × GM × 1/monthly_churn; cap reported LTV:CAC at ~3:1; never propagate 5.7:1 to the pitch.

Escalation rule

When a tripwire fires Any tripwire crossing pages the named owner same-day and adds the risk to the next weekly leadership sync agenda (13-operating-cadence.html). A score-9 tripwire (R1/R2/R4) or any irreversible risk triggers an emergency review within 48h — and, for the COGS/WTP and growth-loop failures, a documented decision in 15-decisions-raci.html. The single org-wide rule: do not scale acquisition spend until R1, R4 and R9 tripwires are green.
