  • Unit Economics: The Numbers That Decide Whether Growth Is Worth Having

    Revenue growth is the most celebrated number in business and one of the least informative on its own. A company can grow revenue indefinitely while destroying value with every additional customer. Unit economics is the discipline of establishing whether that is happening — by reducing a business to the profitability of a single customer or single transaction, and asking whether that unit is worth having.

    Contribution margin: the foundation

    Contribution margin is revenue from a unit minus the variable costs of delivering it — the costs that would disappear if that unit disappeared.

    For a software business this includes hosting, payment processing, third-party licences consumed per customer, and customer support attributable to that account. For a delivery business it includes the courier payment, packaging and transaction fees. It excludes rent, salaried headquarters staff and engineering — those are fixed costs, covered by aggregate contribution, not by any individual unit.

    The distinction sounds pedantic and is decisive. If contribution margin is negative, growth makes things worse. Every new customer widens the loss, and no scale will fix it, because the loss scales with the business. Contribution margin must be positive before any other unit metric is worth calculating.

    Businesses that appeared to be pursuing scale for its own sake have frequently turned out to be businesses whose contribution margin was negative and whose management believed volume would eventually resolve it.

    Customer acquisition cost

    CAC is the fully loaded cost of acquiring one new customer: advertising spend, sales staff compensation including commission, marketing tooling, and the cost of any discount or incentive used to convert.

    Two errors recur constantly.

    Blended CAC. Dividing total marketing spend by all new customers mixes in customers who arrived organically — through word of mouth, search, or existing brand awareness — and who cost nothing to acquire. This produces a flattering number that will deteriorate the moment the company tries to grow faster. Paid CAC — paid acquisition spend divided by customers acquired through paid channels — is the number that governs whether growth can be bought.

    Treating CAC as constant. It is not. The cheapest, most motivated customers are acquired first. As a company scales spend, it reaches progressively less interested audiences and CAC rises. A business modelling future growth at today’s CAC is modelling something that will not happen.

    Lifetime value

    LTV estimates the total contribution margin a customer will generate before they leave. In its simplest recurring-revenue form it is periodic contribution margin divided by the churn rate.

    The simplicity conceals three assumptions that frequently fail.

    • Constant churn. Churn is almost never constant. It is high early — customers who never properly adopted the product leave quickly — and falls among survivors. Applying an average churn rate to a fresh cohort systematically underestimates early losses.
    • Margin, not revenue. LTV built on revenue rather than contribution margin overstates value by exactly the cost of serving the customer. This error is common in investor materials.
    • No discounting. Contribution arriving in year five is worth less than contribution arriving now, particularly for a business that must fund the gap. Undiscounted LTV overstates value, and the overstatement grows with customer lifespan.

    Where a customer’s spending grows over time — through expansion, upsell or usage increases — net revenue retention above 100% can make LTV genuinely large. But that must be demonstrated in cohort data, not assumed.

    The LTV:CAC ratio and its abuse

    Dividing LTV by CAC gives the return on acquisition spend. A ratio around 3:1 is widely cited as healthy — enough margin over acquisition cost to fund fixed overhead and leave profit.

    The ratio is useful and easily manipulated, because LTV is an estimate about the future and CAC is a fact about the past. Extending assumed customer lifespan, using revenue instead of margin, or blending organic acquisition into CAC will each lift the ratio without changing the business at all.

    A very high ratio is not automatically good either. It often means the company is underinvesting in acquisition and leaving growth unclaimed — a signal to spend more, not to celebrate.

    Payback period: the metric that governs survival

    Payback period is how many months of contribution margin are required to recover CAC. For a company that is not yet profitable, it is arguably more important than LTV:CAC, because it determines cash consumption.

    CAC is paid immediately and in full. Contribution arrives gradually. The gap must be financed. A business with excellent lifetime economics and an eighteen-month payback period is a business that consumes enormous cash while growing — and one whose growth stops the moment funding conditions tighten, regardless of how attractive the long-run numbers look.

    Shorter payback also reduces reliance on forecasts. Recovering acquisition cost within a few months depends on near-term behaviour you can observe. Recovering it over three years depends on retention assumptions you cannot yet verify.

    Cohorts are the only honest view

    Aggregate metrics conceal deterioration. A company acquiring customers rapidly will show healthy blended retention simply because new customers have not had time to churn.

    Cohort analysis groups customers by the period they joined and tracks each group separately over time. It answers the questions aggregates cannot:

    • Do later cohorts retain as well as earlier ones, or is the product attracting progressively worse-fitting customers as marketing broadens?
    • Does spend per customer grow within a cohort, or decay?
    • Does retention eventually flatten into a stable base, or decline to zero?

    Deteriorating cohort quality is the single clearest early warning that growth is being purchased rather than earned. It is visible in cohort data months before it appears in headline figures.

    Where the framework breaks down

    Unit economics assumes units are independent. Sometimes they are not.

    In genuine network businesses — marketplaces, communication platforms — each additional participant increases the value of the product to everyone else. Early unit economics can be poor and improve structurally with scale.

    This is a real phenomenon and also the most over-claimed argument in business. The test is evidential: are unit economics measurably improving as the business grows? If cohort contribution margin is rising and CAC is falling as density increases, the network effect is real. If the argument is that economics will improve at some future scale never yet reached, it is a hypothesis being used to defer accountability.

    A working checklist

    • Is contribution margin positive per unit? If not, nothing else matters.
    • Is CAC calculated on paid acquisition, fully loaded, including discounts?
    • Is LTV built on margin, discounted, and derived from observed cohort retention?
    • What is the payback period in months, and can the balance sheet fund it?
    • Are later cohorts as good as earlier ones?
    • Is CAC rising as spend scales?

    A business that answers these cleanly can grow with confidence. One that cannot is running an experiment whose result is not yet known — which is legitimate, provided everybody involved understands that is what it is.

  • How an IPO Actually Works, Step by Step

    An initial public offering is usually reported as an event — a date, a price, a first-day move. It is better understood as a process lasting the better part of a year, in which the visible listing is close to the last step. Most of what determines whether an IPO succeeds happens before anyone can trade the shares.

    Why companies go public

    The textbook reason is capital: selling new shares raises money for expansion without incurring debt. In practice several other motives are often at least as important.

    Liquidity for existing shareholders. Early investors and employees hold stock they cannot easily sell. A listing creates a market. Where an offering consists largely of existing shares rather than newly issued ones, the company itself raises nothing — the proceeds go to selling shareholders. This distinction is disclosed in the prospectus and frequently ignored in coverage.

    Acquisition currency. Publicly traded stock with an observable price is far easier to use as consideration in takeovers.

    Credibility. Audited public reporting and regulatory oversight can matter commercially when selling to large or regulated customers.

    Against these sit real costs: continuous disclosure obligations, audit and compliance expense, exposure to quarterly expectations, and the loss of strategic privacy. Plenty of companies capable of listing decide the trade is not worth it.

    Step one: preparation

    Long before any filing, the company must become capable of being public. That means audited financial statements prepared to the required standard for several prior years, internal financial controls that will survive audit, a board with the requisite independent directors and committees, and the resolution of legacy issues — unusual share classes, related-party arrangements, unclear intellectual property ownership.

    This phase routinely takes a year or more and is where deals most often quietly die.

    Step two: appointing underwriters

    The company selects investment banks to manage the offering. The lead underwriter — the bookrunner — coordinates the syndicate, advises on structure and valuation, and manages the process.

    Most large IPOs are firm commitment underwritings: the syndicate purchases the entire offering from the company at an agreed price and resells it. The banks therefore carry the risk of unsold shares, which gives them a direct interest in pricing conservatively — a structural tension with the issuer, which wants the highest achievable price.

    Underwriting fees are conventionally a percentage of gross proceeds, commonly cited around the mid single digits for smaller offerings and lower for very large ones.

    Step three: due diligence and the registration statement

    Underwriters and lawyers conduct extensive due diligence — financial, legal, commercial — because they carry liability for material misstatements in the offering document.

    The output is the registration statement, filed with the securities regulator. In the United States this is the Form S-1; equivalents exist in other jurisdictions. It contains the audited financials, a description of the business and its strategy, management biographies and compensation, ownership structure, use of proceeds, and an extensive risk factors section.

    For anyone assessing an IPO, this document is the single most valuable source available. It is written under legal liability, which makes it markedly more candid than any marketing material. The risk factors section in particular describes, in the company’s own words, what could go wrong.

    Step four: regulatory review

    The regulator reviews the filing and issues comment letters requiring clarification or additional disclosure. The company files amendments in response. Several rounds are normal, and this correspondence typically becomes public — a useful and underused source, since it shows precisely which claims the regulator thought inadequately supported.

    Importantly, the regulator does not approve the offering as an investment or assess whether the price is reasonable. It assesses whether disclosure is adequate. A company can complete registration and still be a poor investment; that judgement is left entirely to buyers.

    Step five: the roadshow and book-building

    With a preliminary prospectus containing an indicative price range, management presents to institutional investors over roughly one to two weeks.

    Simultaneously the underwriters build the book: collecting indications of interest specifying how many shares each investor would buy at what price. This is the actual price discovery. A heavily oversubscribed book allows the range to be raised; weak demand forces it down, or postponement.

    Communication during this period is tightly constrained by regulation, to prevent the offering being marketed on claims outside the prospectus.

    Step six: pricing and allocation

    The night before trading, the company and underwriters set the final price and allocate shares. Allocation is discretionary, not pro rata: underwriters favour institutions expected to hold rather than immediately sell.

    IPOs have historically tended to price below where they first trade, producing a first-day gain often described as “money left on the table.” Explanations vary — compensation to investors for committing capital to an unproven listing, insurance against a failed deal, and the underwriters’ own incentives among them. Whatever the cause, a large first-day jump is not unambiguously good news for the issuing company: it indicates shares were sold below what buyers were willing to pay.

    Step seven: stabilisation and the greenshoe

    Most offerings include an over-allotment option — the greenshoe — permitting underwriters to sell additional shares, conventionally up to around 15% of the base offering.

    Underwriters typically oversell the deal, creating a short position. If the price rises, they exercise the option to cover. If it falls, they buy shares in the open market to cover instead, supporting the price. This stabilisation is legal, disclosed and time-limited — but it does mean early trading is not purely organic.

    Step eight: the lock-up expiry

    Insiders — founders, employees, pre-IPO investors — are contractually barred from selling for a set period after listing, conventionally in the region of three to six months.

    Expiry is a scheduled, publicly known date on which a large volume of shares becomes sellable. It is one of the more predictable supply events in equity markets, and the terms are disclosed in the prospectus.

    The alternatives

    Direct listing. Existing shares are admitted to trading without a new issue and typically without underwriters. It avoids underwriting fees and first-day underpricing, but raises no capital in its classic form and provides no price support.

    SPAC merger. A private company merges with an already-listed cash shell. It can be faster and allows forward projections to be used in marketing in ways a conventional IPO restricts. Sponsor economics dilute other shareholders, and post-merger performance across the wave of such deals has been widely scrutinised.

    What to read first

    • Use of proceeds — does the company receive the money, or do selling shareholders?
    • Risk factors — read them fully; they are the most honest section.
    • Share class structure — do founders retain voting control through super-voting shares?
    • Lock-up terms and expiry dates.
    • Historical financials, with attention to cash flow rather than reported profit.
    • Related-party transactions in the notes.

  • Reading a Cash Flow Statement: What the Income Statement Hides

    The income statement is the financial statement everyone reads and the one most easily flattered. It is built on accrual accounting, which records revenue when earned and expenses when incurred — regardless of whether any money has moved. That convention exists for good reasons, and it also leaves considerable room for judgement.

    The cash flow statement records only what actually moved. It is the hardest statement to dress up, and reading it against the income statement reveals most of what a company would prefer you not to notice.

    The three sections

    Cash flow from operations (CFO) covers cash generated by running the business — collecting from customers, paying suppliers and staff, settling tax and interest. This is the section that matters most. A business that cannot generate cash from operations is being funded by someone else.

    Cash flow from investing (CFI) covers the purchase and sale of long-term assets: capital expenditure on property and equipment, acquisitions, and proceeds from disposals. Persistently negative CFI usually indicates a company investing in capacity, which is often healthy.

    Cash flow from financing (CFF) covers dealings with capital providers: debt raised and repaid, equity issued, dividends paid, shares repurchased.

    The pattern across the three tells a story on its own. A mature, healthy business typically shows strongly positive CFO, negative CFI as it reinvests, and negative CFF as it returns capital. A young growth business shows negative or thin CFO, negative CFI, and positive CFF — it is consuming cash and raising capital to do so. That is not automatically alarming, but it is a fundamentally different financial position and it depends on continued access to funding.

    The reconciliation is the interesting part

    Most cash flow statements use the indirect method: they begin at net income and adjust their way to CFO. Those adjustments are where the information sits.

    Non-cash charges are added back. Depreciation and amortisation reduced reported profit but moved no cash, so they are restored. Share-based compensation is likewise added back — it is a real economic cost to existing shareholders through dilution, but it consumed no cash. Treating share-based compensation as costless because it is added back here is a persistent analytical error.

    Working capital changes are adjusted. This is the most revealing block:

    • Receivables rising subtracts from cash — revenue was booked, but customers have not paid.
    • Inventory rising subtracts from cash — money is tied up in unsold goods.
    • Payables rising adds to cash — the company is holding onto money by paying suppliers later.

    Each of these can be benign or a warning, and the way to tell is to compare the rate of change against revenue growth.

    The divergence that matters most

    The single most useful check available to a non-specialist is this: track net income and cash flow from operations over several years and see whether they move together.

    Over time, for a genuinely profitable business, they should. Accrual timing differences wash out across periods. Reported profit rising steadily while CFO stagnates or falls is the classic signature of earnings quality deteriorating.

    The common explanations are worth knowing:

    • Receivables growing faster than revenue. Sales are being booked to customers who are slower to pay, or who may not pay at all. This can indicate loosened credit terms used to hit sales targets.
    • Inventory growing faster than revenue. Goods are being produced or bought faster than they sell. A write-down may be coming.
    • Capitalising costs that were previously expensed. Moving a cost from the income statement to the balance sheet raises reported profit immediately and defers the charge into future depreciation. Watch for capitalised software development or capitalised customer acquisition costs rising sharply.
    • Payables stretching. Delaying supplier payment flatters cash flow, but it is a one-time benefit that cannot repeat indefinitely and may signal liquidity strain.

    Free cash flow, and its definitional trap

    Free cash flow is conventionally CFO minus capital expenditure — the cash left after maintaining and expanding the asset base, available for debt repayment, dividends, buybacks or acquisitions.

    Two cautions apply.

    First, FCF is not a standardised accounting measure. Companies define it differently, and adjusted definitions in investor presentations frequently exclude items — restructuring, acquisition costs, occasionally share-based compensation — that a stricter reading would include. Always check the definition against the statement itself.

    Second, capital expenditure mixes maintenance and growth. Maintenance capex sustains existing operations and is genuinely obligatory; growth capex is discretionary and expands capacity. A company can raise reported free cash flow simply by underinvesting, which improves the figure while degrading the business. Sustained capex below depreciation, in a capital-intensive industry, is worth a hard look.

    What the cash flow statement will not tell you

    It is not a complete picture, and its limits are as important as its strengths.

    • It says nothing about leverage or solvency — that is the balance sheet’s job. A company can show healthy CFO and still be dangerously indebted.
    • Classification carries discretion. The placement of interest paid and received varies across accounting frameworks, which affects reported CFO and complicates cross-border comparison.
    • One-off items distort single periods. An asset sale, a legal settlement or a tax refund can flatter or depress a single year. Read several.
    • Cash flow can be timed. Accelerating collections or deferring payments around a period end shifts cash between reporting periods without changing the underlying business.

    A practical sequence

    • Pull five years of net income and CFO side by side. Do they track?
    • Compare receivables and inventory growth to revenue growth.
    • Check capex against depreciation for signs of under- or over-investment.
    • Identify how the business is funded: is CFF consistently positive, and if so, why?
    • Read the company’s own free cash flow definition before comparing it to anything.
    • Scan the notes for changes in accounting policy or classification between periods.

    None of this requires financial modelling software. It requires reading three statements together rather than one in isolation — which is, in practice, the difference between analysis and headline-reading.
