Founders often live inside their P&L without stepping back to see how it connects to cash and the balance sheet and that gap can be costly when it's time to raise, forecast, or simply understand whether the business is actually healthy. This masterclass breaks down the three core financial statements every founder needs to read fluently: the P&L, which shows performance; the cash flow statement, which shows liquidity and runway; and the balance sheet, which shows financial position. Using real examples :a sale, an amortization, it shows exactly how a single transaction ripples across all three.
The figures presented are fictitious and provided solely for illustrative purposes.

P&L shows financial performance over a specific period (month, quarter, or year)
COGS = cost of production or sale (raw materials, manufacturing expenses, salaries of Sales representatives…)
SG&A = operating costs of running the business (salaries, rent, marketing…) which are not directly tied to the production of goods.
EBITDA = key indicator of a company's operating performance without non-operational factors.
Startups almost always have negative EBITDA as it is part of a growth strategy to invest in research, development, and customer acquisition.
EBITDA Margin % = (EBITDA / Total Revenue) x 100
Assess operational performance, easier to compare and evaluate efficiency and profitability of businesses

The contributive margin is the difference between a company's revenue and its cost of goods sold (COGS). Direct costs related to sales are included. It represents the portion of revenue available to cover fixed costs and generate profit.
Contains non-accounting metrics such as:
Startups often incur negative EBITDA, intentionally prioritizing growth and development over short-term profitability
To monitor this growth efficiency, we check that this ratio goes toward 1 (which is what a late stage company should aim):
Net burn / Net new revenue (12 months)
A lower ratio (<1) is preferable because it indicates that the company is generating more new revenue than it is burning cash

Cash flow statement helps us understand how money is being managed within the company
Clear picture of a company's liquidity, ensuring that there's enough cash to cover operating, investing and financing activities
Track the cash burn and cash burn rate => identifies areas where cost control is necessary.
By knowing the cash burn rate and the current cash reserves, we can define how long the company can operate without running out of cash = runway
Objective is to understand what happens between Cash BoP and Cash EoP

CF operational + investments + financing = cash-flow of the period
FY cash variation = (5 769 - 9 837) = - 4 067
Monthly cash burn (from last quarter) = (1 259 / 3) = 420
With this burn, the company's runway is 14 months (5 769 / 420)
Balance sheet is a snapshot of a company's financial position at a specific point in time
It helps assess a company's financial health and stability
Shows what a company owns (assets), what it owes (liabilities), and the residual interest (equity) for its shareholders
Assets — What the company owns
Liabilities + Equity — What the company owes
Net debt = Financial Debts - Cash & Cash Equivalents = 4 200k + 500k - (8 500k + 5 500k + 500k) = - 9 800k€
The aim for a company is not using its equity to run the operation but its working capital
Working capital = current assets – current liabilities.
The company makes a sale for €100k
(for this example, we assume that no additional sales effort, and therefore no additional cost, was made to achieve this sale, we also assume that there are no VAT)
