ICP Brief

We sell to the learner who watches native content on a desktop, daily.

One primary segment, settled org-wide: serious immersion-method language learners (Japanese/Korean/Chinese-first) who live in native desktop video clients and already pay $60–180/yr for tools. Everyone else is an Anti-ICP.

Bar for good A junior SDR could open this Monday and start qualifying real accounts and seeding real communities without asking the founder a single question.
Validation status — read before trusting any field Everything below is [HYPOTHESIS]. The entire customer model is desk-derived from RECON. One [PAST] datum exists ("a prototype works"); zero completed interviews, zero LOI/prepay. Fields tagged [HYP] are falsifiable claims to test in the Week-1 run (15–20 learners, Mom Test script verbatim, <30% kill-criterion), not findings. The WTP band is the #1 thing to validate.

Ideal Customer Profile — primary segment (org-wide, final) [HYP — pending Week-1 interviews]
1 · Segment name
Serious immersion-method language learners (JA/KO/ZH-first)
2 · Company size
N/A — consumer / prosumer individual
3 · Industry (NAICS)
611 (educational services), 519 (info) — consumer
4 · Geography + TZ
Global English-first: US, EU, LATAM, SEA. Heavy in US/UK/AU + Brazil
5 · Tech stack required

Self (individual)
8 · User title
Self
9 · Champion title
Subreddit/Discord power user; polyglot YouTuber who recommends tools
10 · Economic buyer
Self (sub $10–20/mo discretionary)
11 · Trigger event
Hit the "intermediate plateau"; started sentence-mining; committed to a "watch-only-native-content" challenge; failed JLPT/HSK and doubled down on immersion
12 · JTBD functional
"Understand native speech in real time while keeping the original audio so I still train my ear"
13 · JTBD emotional
"Stop feeling locked out of the content I want; stop the shame of pausing every sentence"
14 · JTBD social
"Be the person in the Discord who finished the immersion challenge / understands the stream live"
15 · Current solution
Yomitan + manual subs, asbplayer, Language Reactor, fan-sub Discords, YouTube auto-translate, raw pausing/rewinding
16 · Current spend/yr
$60–180 (Migaku ~$8/mo, Language Reactor ~$5–9/mo, Anki add-ons, Patreon to fan-subbers)
17 · Pain severity
P1 — blocks the core activity, but workarounds exist
18 · Pain frequency/wk
7–21 (daily-to-multiple-daily content sessions)
19 · WTP band
$6–12/mo ($96–144/yr), capped by free extensions ⚠ ceiling < COGS floor — validate first
20 · Decision cycle
1–7 days (impulse / trial-led, community-recommended)
21 · Watering holes
r/LearnJapanese, r/languagelearning, r/Korean; Refold / TheMoeWay / Migaku Discords (see §watering holes)
22 · Disqualifiers
Casual learner; mobile-only; wants 100% replacement of original audio (defeats the learning job)
23 · Acquisition channel
Polyglot/immersion YouTuber sponsorships + Refold/MoeWay community seeding + SEO "watch [lang] content with translation"
24 · Hero mode (monetized surface)
Subtitle / dual-track (whisper-dub under original) + Anki export — NOT auto-mute dub
25 · Secondary hedge
Foreign-content creators / VTuber-clip translators — served by an async/batch high-quality SKU, do NOT dilute the live wedge

Persona A named example, and an honest gap.

M

"Kenji-track" Mei, 24 — immersion learner (PRIMARY)[HYP — constructed composite]

Marketing analyst by day · 2 hrs/night Japanese immersion · Tokyo content, US timezone

Day-in-life pain. It's 9pm. Mei opens a live Japanese VTuber stream on the native desktop YouTube/streaming client — no fan-sub exists. She catches ~40%, rage-pauses to look words up in Yomitan, loses the flow, gives up after 20 minutes and rewatches an old subbed clip instead.

Current alternatives. Yomitan (text only), waiting days for fan-subs, asbplayer (recorded only), Language Reactor (browser tabs only). None touch live or native-client audio.

Switch blockers. Fears an AI dub will make her lazy; already pays Migaku and resents another subscription; skeptical the latency will feel natural rather than a delayed echo.

Caveat: Mei is a desk-built composite, not a real interviewee. The "~40% / 20 min / rage-pause" detail and the blockers are hypotheses to confirm or kill in the Week-1 run.

Persona B — intentionally not invented The previously-drafted "Clipper Diego" composite was removed (constructed persona). After the Week-1 interviews, replace this with ONE verbatim-sourced narrative from a real learner: their actual app + content, the dated last-time-it-hurt moment in their words, the real tool-spend line items, the literal switch blocker. Source = transcript ID, not authorial imagination. Until then this is a known gap, not a finding.

Decision-making unit A consumer DMU is one person wearing four hats.

For a $12/mo individual purchase there is no committee — the learner is buyer, user and economic buyer at once. The leverage is the community champion (the only "other person" in the unit) and the blocker is internal: the fear that an AI dub corrupts the learning. Reach the champion, defuse the blocker, and the buy is impulse-fast.

Role Title What they care about How to reach
Champion Polyglot YouTuber / Discord power-user / immersion-challenge mod Recommending tools that actually work; their audience's results; not shilling junk Sponsor a video; give early access + a custom challenge integration; let them gatekeep quality
Economic buyer Self — the learner (sub $10–20/mo discretionary) Not stacking yet another subscription; value vs. the free Yomitan workaround they already run Free trial timed to a challenge kickoff; price below the Migaku line they already pay
Blocker Internal "purist" voice (+ the community's anti-crutch culture) "Will a dub make me lazy / stop me hearing real speech? Is it accurate enough to trust?" Lead with subtitle/dual-track that PRESERVES original audio; show accuracy; never default to auto-mute
End user Self — the learner at 9pm in front of a native stream Following live native content at near-full speed while still training the ear; one-click setup In-product onboarding tied to "your stream tonight"; ≥4 sessions/wk = activated

20 named target accounts For a consumer wedge, "accounts" = communities & creators.

There is no B2B logo to chase — the buy is individual. So the operative "accounts" are the distribution nodes where the ICP already congregates: subreddits, immersion Discords, polyglot creators, and the tool ecosystems they live inside. The "suspected champion" is the mod / founder / creator who gatekeeps tool recommendations. Member counts are live as of May 2026.

Disqualifiers & watering holes Who to walk away from — and where to show up.

Disqualifiers — do NOT sell to
7 hard exclusions (the Anti-ICP)
  • Remote teams on Zoom/Meet/Teams — native platform features are free, zero-install, owned by the incumbent. The BRIEF's headline persona; do not lead here.
  • "Anyone watching foreign video" — no trigger, no community, zero WTP next to free captions. Marketing to everyone = to no one.
  • Professional simultaneous interpreters — an AI dub replaces their billable output; competitors-by-proxy, not buyers.
  • Casual / mobile Duolingo users — wrong device, wrong job (gamified streaks ≠ comprehension), zero WTP.
  • Enterprise localization / dubbing studios — want offline, frame-accurate, human-QA'd output; real-time speed is irrelevant.
  • Mobile-only learners — no desktop = the native-capture moat doesn't reach them until mobile capture ships.
  • Wants 100% audio replacement — full auto-mute dub defeats the learning job; signals a non-learner who'll churn.
Watering holes — show up here
Named, with 100+ ICPs each
  • r/LearnJapanese (~700k) · r/languagelearning (~3M) · r/Korean · r/ChineseLanguage (~400k)Tool-recommendation-driven; SEO + AMA + thread seeding
  • Refold / TheMoeWay / Migaku DiscordsMigaku ~12k each (JA/KO/ZH); the exact "watch native content" thesis; run calendar-timed immersion challenges = built-in triggers
  • Polyglot / immersion YouTubersMatt vs Japan, Livakivi, GO! Billy Korean — sponsorships + tool-mention placements
  • Tool ecosystemsYomitan, asbplayer, Anki communities — users with the exact gap we fill (live + native-client)
  • VTuber clipper / fan-sub Discords + TwitterSecondary hedge — confirmed manual-subbing labor pools (green-flag existing workaround); target with the async/batch SKU
Distribution thesis verdict Intact for the immersion-learner niche; BROKEN for the broad-consumer pitch. We can name a hole with 100+ ICPs comfortably — the niche congregates densely and on a calendar. There is no congregation point for "anyone watching foreign video." This is the core reframe versus the BRIEF.
