Every piece of wiki jargon in one place — market terms, product terms, and our own coinages. Sorted alphabetically; each term is a heading, so it can be linked by anchor. The Russian page carries the fuller definitions; this page is the brief pair. New terms go here, not into per-page mini-glossaries.
Adversarial review (адверсариальная проверка)
Fact-checking where independent agents try to DISPROVE the text against primary sources rather than confirm it. The seven-country page survived one: 44 claims confirmed, 16 corrected.
Aggregator (агрегатор)
An app that bundles fragmented purchases into one place (e.g. all of a country's fishing permits, like Sweden's iFiske). In Latvia the license-aggregator wedge is dead — Mana Cope owns sales — so we integrate, not aggregate.
B2B / B2C / B2G
Who we sell to: consumers (anglers), businesses (pond owners, tackle shops, brands), or government. Our money is likelier in B2B/B2G than in angler subscriptions.
CAC
Customer acquisition cost: marketing spend per new user or payer. Phase 0 targets near-zero CAC via quiet seeding in free channels.
Check-in (чек-ин)
A one-tap "I am here now" mark.
Cohort (когорта)
A group of users who arrived in the same week, tracked separately: did THEY come back, not "someone somewhere".
Cold start (холодный старт)
The empty-product problem: no reports → useless map → nobody reports. Cured by seeding data and launching at a traffic peak (first ice).
Compliance (комплаенс)
Following the rules and the law. For the angler: "am I fishing legally?"; for us: a whole wedge — make the legal obligation painless.
Conversion (конверсия)
The share moving to the funnel's next step: visitor → registered, free → paying. Category benchmark for paid subscriptions: 1.5–3% of MAU (RevenueCat median 1.7%, Fishbrain 1.4%).
Critical path (критический путь)
The task chain that sets the whole project's deadline: slip any link and the finish slips. Ours: Konstantins' answers + the survey.
Crowdsourcing (краудсорсинг)
Collecting data from the users themselves. Works for non-sensitive data (depths, ice, rules); breaks on bite spots.
Customer discovery / custdev (кастдев)
Talking to real users instead of guessing: interviews, surveys, observed behavior. Ours right now: 11 questions to Konstantins plus the survey.
Data flywheel (маховик данных)
A self-reinforcing loop: more reports → better map → more anglers → even more reports. The specialized 10% spin it; the casual 90% consume aggregates.
DAU / MAU
Daily / monthly active users. The DAU/MAU ratio separates habit from occasional visits; L7 = days active out of the last seven.
Deep link (диплинк)
A link straight into the right place of another service — e.g. from our app directly to buying a specific license in Mana Cope. The working tool of "integrate, don't aggregate".
Design freeze (заморозка дизайна)
The moment the feature set stops changing: build only, add nothing. Mid-August in the phase plan.
Doorway pages / programmatic SEO (страницы-приманки)
Auto-generated pages made by the thousand so Google finds the site. Fishbrain's Denmark page lists bass — a fish Denmark does not have: a template built it, no human looked.
Feed (лента)
A social feed of catch photos — Instagram, but fish. Fishbrain's core product and the losing move on all seven Baltic markets.
Freemium (фримиум)
Base product free, premium paid. Casual anglers are the freemium audience: they won't pay, but they feed liquidity and click the deep links.
Funnel (воронка)
The user's path in steps: heard → opened → registered → returned → paid. People drop at each step; the funnel shows where.
Gate (гейт)
A checkpoint with criteria written down in advance: read the numbers, then continue or rebuild. Pre-committed thresholds, not "maybe" — the go/no-go between phases.
Heatmap (тепловая карта)
Activity shown as color "heat" over zones, no individual points. Ours ship with k-anonymity and a publishing delay, so the bite window closes before the crowd arrives.
Incumbent (старожил, инкумбент)
The player already sitting on the market when you arrive: Mana Cope, the forums, the FB groups. In Poland the incumbents digitized the rail themselves and the window closed.
k-anonymity (k-анонимность)
A privacy rule: a point or heat cell renders only when at least K people stand behind it, so no individual can be singled out.
Lead (лид)
A potential customer who left contact info or showed interest but hasn't bought. Phase 0's winter waitlist is lead collection for the first-ice launch.
Liquidity (ликвидность)
Enough live users nearby for the product to be useful: an empty report map means no liquidity. The category's core scarcity — nobody built it in seven countries.
Moat (ров)
Buffett's term: the business is a castle, the moat is the water around its walls. Protection from copying — what keeps a competitor from taking your users even when he sees everything you do and has more money. An advantage helps today; a moat keeps working under attack. Ours = local liquidity × trust.
MRR / ARR
Monthly / annual recurring revenue from subscriptions. The brutal math: 400–800 payers yield only ~€10–25k ARR — consumer subscriptions alone are not a business.
MVP
Minimum viable product: the smallest version you can hand to real users to test the core hypothesis. Ours is the Phase 1 ice mode.
Network effect (сетевой эффект)
The product gets more useful as more people use it. In fishing the effect is local: Fishbrain's US millions buy nothing on a Latvian lake.
Onboarding (онбординг)
The user's first minutes in the product: how fast they see why it's for them. 35% of annual-plan cancellations happen in month one — onboarding must prove value immediately.
P2P
Peer-to-peer deals: angler pays angler (paid knowledge sharing, guiding, teaching) with the app as the middleman. See P2P opportunity.
Paywall (пейволл)
A payment barrier: content or features visible to subscribers only. Fishbrain's most hated move was paywalling community reports; our principle P10 forbids it.
"Present but dead" (присутствует, но мёртв)
The app can be downloaded but nobody uses it: the country is formally "covered", actually empty. Fishbrain's diagnosis in all seven Baltic countries, home market included.
Put-and-take pond (платник)
A paid stocked pond: pay, catch, keep. "What's biting" there is the owner's merchandise, not a shared secret — so the layer dodges the secret-spot problem; booking is undigitized region-wide.
PWA
A web app that opens from a link and installs to the phone like a normal app, bypassing the app stores: faster to ship, instant to update. Phase 0 ships as a PWA.
Rail (рельс)
The mandatory transaction: whatever the angler must buy or file with the state — permit, license, catch report. Whoever owns the rail owns the flow of anglers; on all seven Baltic markets the feed lost to the rail owner.
Retention (удержание)
Do users come back: the share of a cohort seen again a week or month later. Phase 0's gate metric — real weekly returns, not downloads.
Rival good (конкурентное благо)
A good that degrades when shared: a fishing spot — share it, lose it. Opposite: non-rival (fuel prices don't change when everyone knows them). The wiki's core thesis rests on this distinction.
Sonar / fish finder (эхолот)
A device that shows depth and fish below the surface. Deeper's home is Lithuania; a decade of sonars in anglers' pockets built no social network by itself.
Spot burning (палить точки)
Publicly exposing fishing spots — the culture's central taboo ("share it, lose it"). Fishbrain never lived down "the spot-burner app"; our defense is principles P1–P6.
Stakeholder (стейкхолдер)
Everyone with a stake besides the users themselves: pond owners, tackle shops, clubs, VVD, BIOR, municipalities. Each pays in its own currency — money, data, or legitimacy.
Table-stakes
The ante: the mandatory minimum that gets you a seat at the table but wins nothing. Our rules engine is exactly that — required, but no moat.
Utility (утилита)
A useful tool with no social layer: rules, maps, checks. Phase 0 is pure utility, deliberately feed-free.
"Verify precisely, publish coarsely" (проверяй точно — публикуй грубо)
Our geolocation rule: the app privately records exact GPS as proof of honesty, but publicly shows only the waterbody/sector. Precision buys trust and report weight; it never burns spots. External echo: Norway's laksebørs publish river totals, never locations.
Wedge (клин)
The market entry point: the gap a new product can slip through and hold without fighting everyone at once. A wedge is a window, not a moat — it lives only while the state rail is bad (Estonia's lesson).
Winner-take-most
In locally-networked markets the second player on the same lake gets almost nothing. Hence the bet on speed to first ice.
WTP / willingness to pay (готовность платить)
What a person will actually spend. A Latvian angler's app ceiling: €19.99–29.99/year; the full WTP ladder — from a €1.50 fishing card to hundreds of euros on a boat — is in segments.
