Finance / Business-Performance Summary (Cohorts & “Economy” Model)

The presenter builds a cohort-based marketing accounting model across 12 cohorts / 12 months to show how marketing decisions—such as acquisition spend and retention/reactivation—affect:

  • the current cohort immediately, and
  • all past cohorts over time (via returning users),

which then determines an “economy” metric (cashflow/profit-like balance).

Disclosures: The subtitles include no explicit “not financial advice” disclaimer.


Instruments / Assets / Tickers / Sectors Mentioned

  • None. The content is focused on operational/marketing analytics, and the only numeric values referenced are marketing costs in rubles.

Key Entities / Metrics Used

Cohort Grid Components (Table Tabs & What They Track)

  • Marketing tab: audience acquisition costs (“costs for attracting an audience”).
  • Traffic tab: number of incoming users per cohort per month.
  • Returns / reactivations: returning users over time (“returns while slides”).
  • Clients per cohort per month: number of clients each month for each cohort.
  • Transactions per month: includes repeat purchases within cohorts.
  • Conversion rate: conversion measured per month within a cohort (and “starting conversion” is mentioned).
  • Average cost per click (CPC).
  • Cost per visitor (CPV): derived from marketing spend / cohort traffic.
  • Revenue / money turned over: revenue generated from visitors/transactions.
  • “Economy” metric: revenue minus marketing spend (examples below).
  • ARPU: discussed as growing/stabilizing.

Methodology / Step-by-Step Framework

  1. Set up cohort accounting

    • Assume 12 cohorts formed over 12 months.
    • For each cohort, track month-by-month:
      • new-user inflow
      • returning/reactivated users
      • repeat purchases / transactions
      • conversion rate and transaction volume
      • acquisition cost drivers (e.g., CPC, cost per visitor)
  2. Compute unit economics per cohort per month

    • Use acquisition costs and traffic to compute cost per visitor.
    • Multiply conversions by transaction frequency to compute revenue (“money we were able to turn over”).
  3. Compute “economy” per cohort

    • Economy = revenue from cohort (including repeats) − marketing spend
  4. Simulate scenario changes

    • Change acquisition spend month-to-month (e.g., keep at 75k vs increase).
    • Add retention/reactivation spend (e.g., “work … with … warmth of bees” to bring back old users).
    • Observe how outcomes propagate:
      • the current cohort reacts immediately
      • prior cohorts improve later due to returning users
  5. Use the full cohort table

    • Extend/fill the table through the end of the timeline to see cumulative effects.
    • Compare how long it takes until each cohort’s monthly economy turns positive (“positivity timing”).

Key Numbers & Explicit Scenario Outcomes (Examples)

Values are in rubles. Figures are described with round numbers, and some subtitle-derived values appear partially garbled.

Baseline Example: Cohort 1

  • Month 1 (January) marketing spend: 75,000 rubles
  • Users/clients acquired from this spend: 15 users (wording suggests “use” = users)
  • Transactions from those clients: 110 transactions (includes repeat/conditional repeats)
  • Economy for cohort 1 after month 1: -25,500 rubles
    • Economy is negative because there is not enough return in the first period.

February: Increased Spend + Retention/Reactivation

  • Marketing spend in February: 75,000 rubles
  • Model adjustments described:
    • “price has increased” / fewer users for the same spend (e.g., from 15 down to about 14 / 70,000 referenced)
    • plus reactivation:
      • spend 5,000 rubles to bring back old users
      • returning users added: 5 (example)
  • Economy improvement example (cohort 1):
    • economy improves from -25,500 to 24,650 rubles (becomes positive)
  • Economy for cohort 2: described as still negative

March: Higher Acquisition Spend

  • Planned March spend: 80,000 rubles
    • Subtitles also reference 75,000 and additional 10,000 (inconsistent due to garbling)
  • Result described:
    • cohort economies shift; cohort 1 worsens slightly, 2 improves, and 3 becomes best
    • the presenter emphasizes changes propagate across all cohorts, not only the newest one.

Major Campaign Scenario

  • Total “culture-based advertising campaign” budget: 100,000 rubles
  • Budget distribution examples mentioned:
    • 85,000 into one channel
    • 7,000 into another
    • 8,000 left/other (plus small additional allocations like 6, 2,000, etc., shown as garbled)
  • Claimed effect:
    • “conversion has grown sharply by month”
    • later cohorts reach near/positive states while early months for cohort 1 remain negative (first-month lag)

End-State / Filled-Table Example

  • Total marketing expenses across cohorts in the model: 1,700,000 rubles
  • Growth assumptions (partially garbled but key points):
    • traffic grows from 10,000 baseline to 10,000+ over time
    • returning users increase from around 500 in early months to higher levels later
  • Outcome described:
    • by the end of the modeled history, all cohorts show positive dynamics
    • cohort 1 takes longer to become positive due to initial negative months.

Performance Comparison / Ranking

  • Cohort 1 produces the most money in the model:
    • referenced value: 199,000 (described as highest)
  • Even though early months were negative, growth occurred as:
    • conversion increased
    • ARPU stopped growing after learning improvements around March (explicitly mentioned)

Explicit Recommendations / Cautions

Recommendation

  • Use a cohort-by-cohort table to understand:
    • accumulation timing, and
    • cross-cohort effects of marketing decisions.
  • The presenter states they will make the table public and provide links (in the description) to prior videos covering related concepts.

Caution / Interpretation

  • A single analytics number (e.g., cumulative revenue) can be misleading:
    • you don’t earn it immediately; it accumulates over time across cohorts.

Operational Conclusion

When increasing spend, account for:

  • the immediate effect on the current cohort’s acquisition
  • the delayed effects on prior cohorts via retention/reactivation
  • the possibility that monthly conversion metrics may not fully reflect cumulative cohort impact
