📖 1. Financial Statements and Cash

📝 Essential Points

📌 The balance sheet is a snapshot at a specific date, whereas the income statement is a film covering a period and cash flow tracks actual money entering and leaving the business.

📐 Formula - The balance sheet must satisfy $\text{Assets} = \text{Liabilities} + \text{Equity}$.

📐 Formula - The income statement calculates $\text{Profit} = \text{Revenue} - \text{Expenses}$.

📌 Revenue is not cash received, and profit is not cash: a company can make a profit while lacking cash or hold cash while making a loss.

📖 2. Accounting Traps and Tax

🔑 Key Concepts & Definitions

• Depreciation: an expense in the income statement that reduces the carrying value of a fixed asset on the balance sheet without creating a new cash outflow

★ Must-know

📌 When a loan payment is made, interest is an income-statement expense, principal repayment reduces the balance-sheet debt, and the total payment is a cash outflow.

📌 In the course model, corporate tax equals 25% of the year's cumulative positive pre-tax income, is recorded as an expense and a tax liability, and is paid in March of the following year.

Further detail

• For a machine bought for €12,000, cash decreases by €12,000 at purchase, while subsequent annual depreciation creates an expense without another related cash outflow.

• A €700 loan payment consists of €80 interest and €620 principal repayment, so €80 is an expense and €620 reduces the debt.

💡 Memory Hook

Interest is an expense, principal is debt repayment, and depreciation is an expense without cash outflow.

📖 3. Balance Sheet and Cash Metrics

📝 Essential Points

📐 Formula - Net fixed-asset value satisfies $\text{Net value} = \text{Gross fixed assets} - \text{Accumulated depreciation}$.

• Balance-sheet items include:
  • fixed assets
  • inventories
  • trade receivables
  • cash
  • share capital
  • cumulative profit
  • outstanding loan principal
  • tax payable

📌 The loan balance on the balance sheet is the principal still owed, not future interest.

📐 Formula - Runway measures the number of months before cash is exhausted: $\text{Runway} = \frac{\text{Available cash}}{\text{Monthly burn}}$.

📐 Formula - Customer acquisition cost satisfies $\text{CAC} = \frac{\text{Marketing and sales spending}}{\text{New customers}}$, and the course gives an LTV/CAC objective greater than 3.

📖 4. Contribution Margins and Break-Even

★ Must-know

📐 Formula - For a product, contribution margin equals $\text{MSCV} = \text{Revenue} - \text{Variable costs}$ and operating result equals contribution margin minus product-specific and common fixed costs.

📐 Formula - The contribution-margin rate satisfies $\text{MSCV rate} = \frac{\text{MSCV}}{\text{Revenue}}$.

📐 Formula - The break-even model is $R = m \times CA - CF$, where R is result, m is the margin rate, CA is revenue, and CF is fixed costs.

📐 Formula - Additional revenue needed to finance additional fixed costs is $\Delta CA = \frac{\Delta CF}{\text{Margin rate}}$.

Further detail

• With €8,000 of new fixed costs and a 60% margin rate, the required additional revenue is approximately €13,333.

💡 Memory Hook

Higher fixed costs require additional revenue through the contribution margin.

📖 5. Forecasting Production and Stocks

★ Must-know

📐 Formula - The seasonal coefficient satisfies $\text{Coefficient} = \frac{\text{Observed sales}}{\text{Corrected sales}}$, so corrected sales equal observed sales divided by the coefficient.

📐 Formula - A monthly forecast equals $\text{Trend} \times \text{Seasonal coefficient} \pm \text{Commercial-action effect}$.

📐 Formula - Workshop load satisfies $\text{Load rate} = \frac{\text{Theoretical consumption}}{\text{Workshop capacity}}$, with an objective close to 100% without exceeding capacity.

📐 Formula - Stock days satisfy $\text{Stock days} = \frac{\text{Stock}}{\text{Monthly consumption or sales}/30}$.

Further detail

• Sales of €28,200 with a seasonal coefficient of 1.2 correspond to corrected sales of €23,500.

• The model uses 0.15 kg of bondillon for a classic soap, 0.15 kg of each fragrance for a Duo, and a machine capacity of 9,100 minutes per month.

💡 Memory Hook

Trend → seasonality → forecast → production capacity → stocks.

📖 6. Working Capital and Performance

📝 Essential Points

📐 Formula - Working capital requirement satisfies $\text{WCR} = \text{Inventories} + \text{Trade receivables} - \text{Trade payables}$.

📐 Formula - Net cash satisfies $\text{Net cash} = \text{Working capital} - \text{Working capital requirement}$.

📌 The cash flow requirement increases when inventories, receivables, or customer payment delays increase, but decreases when supplier payment delays increase.

📐 Formula - Self-financing capacity satisfies $\text{CAF} = \text{Net income} + \text{Depreciation and provision charges}$ because these charges reduce accounting profit without being cash outflows.

• 🔄 The management-income cascade is:
  1. revenue
  2. gross margin
  3. value added
  4. EBITDA
  5. EBIT
  6. pre-tax income
  7. net income

💡 Memory Hook

Stocks and receivables increase working capital needs, which reduces net cash.

📖 7. Startup Metrics and Strategies

★ Must-know

📐 Formula - Burn is net monthly cash consumption, while runway satisfies $\text{Runway} = \frac{\text{Cash}}{\text{Burn}}$.

Further detail

📐 Formula - A platform's commission revenue satisfies $\text{Revenue} = \text{GMV} \times \text{Take-rate}$.

📐 Formula - For consumer applications, engagement intensity satisfies $\text{DAU/MAU} = \frac{\text{Daily active users}}{\text{Monthly active users}}$.

• For subscription startups, NRR above 100% means the existing customer base grows in revenue without requiring new customers.

📖 8. Strategic Decisions and Sensitivity

📝 Essential Points

• Buying 500 units while selling 200 creates a cash payment for 500 units, an income-statement variable cost for only the 200 sold, and inventory for the 300 remaining units.

• Renting creates a rental expense and regular payments, whereas buying creates a fixed asset, depreciation, possible borrowing, and a larger initial cash outflow.

• Sensitivity analysis varies approximately four to five key variables, often by plus or minus 20%, and examines cumulative net income and minimum cash to identify dangerous thresholds and assumptions requiring verification.

💡 Memory Hook

The same economic decision can have different accounting and cash effects.

📖 9. Financing and Fundability

🔑 Key Concepts & Definitions

• Fundability: the ability of an idea or startup to appear credible and attractive enough to be financed through a critical problem, reachable market, timely opportunity, qualified team, real innovation, and plausible financing path

★ Must-know

• The three financing paths are:
  • fundraising
  • building an asset for resale
  • bootstrapping through customer-funded profitability

📌 A durable moat comes from defensible assets such as proprietary usage data, distribution, or professional trust, whereas using the best available AI model alone is not a durable moat.

📌 Verticalization solves a deep problem for a specific profession or sector, whereas a horizontal solution targets many businesses generically.

Further detail

• The course gives these financing ranges: love money €1,000–€30,000, grants €5,000–€30,000 or more, bank or honor loans €10,000–€100,000, business angels €50,000–€500,000, and seed or venture capital €300,000–€3 million or more.

💡 Memory Hook

Problem → market → timing → team → innovation → financing.

📖 10. Responsible Use of AI

🔑 Key Concepts & Definitions

• Hallucination: false information presented confidently, such as an invented number, source, quotation, competitor, or URL
• Cognitive debt: the gradual loss of reasoning, memory, and independent construction skills caused by letting AI perform too much of the work
• Sycophancy: an AI tendency to agree with and confirm the user's assumptions instead of genuinely criticizing them
• Workslop: content that looks like work but lacks substantive analysis, verification, or personal reasoning

📝 Essential Points

• The four responsible AI practices are:
  • Delegation
  • Description
  • Discernment
  • Diligence

📌 Real personal, customer, contractual, internal, and confidential data must not be entered into AI systems; interviews must be anonymized, in line with the course's reference to the GDPR and AI Act.

💡 Memory Hook

Hallucination invents information, sycophancy agrees too easily, and workslop only looks like work.
