For startups and high-growth companies, raising capital (funding rounds) or completing capital increases is a common lever to accelerate product development, sales execution, and expansion.<\/p>\n
However, it is also one of the areas where misunderstandings most frequently arise, because pre-money<\/em> and post-money<\/em>are not just \u201ctwo numbers\u201d: they determine the price per share\/unit, the ownership percentage the investor is buying, the dilution borne by existing shareholders, and\u2014ultimately\u2014the architecture of the capitalization table (cap table) through which future economic rights and control are distributed.<\/strong><\/p>\n In private markets, price is not \u201cdiscovered\u201d the way it is in public markets; it is negotiated. That is why understanding these metrics (and what is included in them) is essential to keep the transaction transparent and to avoid information asymmetries that later create friction in the shareholders\u2019 agreement or in subsequent rounds.<\/p>\n Pre-money<\/em> valuation is the value of a company before receiving external investment.<\/strong> In other words, it refers to the value investors assign to the company based on its assets, capabilities, track record, team, market, and growth potential\u2014excluding the new capital that will be injected in the funding round.<\/p>\n This figure reflects the price investors are willing to pay for the company in its current state, considering all the factors that define its value at that point in time. Pre-money<\/em> valuation is therefore critical to determining the company\u2019s value before existing shareholders are diluted by the new investment.<\/p>\n Pre-money<\/em> is the number that reflects how much the business is worth based on its assets, team, technology, traction, and potential\u2014without adding the cash that enters in the round.<\/p>\n In practice, pre-money<\/em> serves three purposes:<\/p>\n The typical mistake is not only confusing pre<\/em> with post<\/em>, but failing to clarify whether the calculation is based on \u201cissued\/outstanding\u201d equity or on a fully diluted<\/strong> basis. In a professional analysis, \u201cfully diluted\u201d generally includes (depending on the case):<\/p>\n This matters because the pre-money<\/em> valuation can remain the same on paper, while the founders\u2019 true ownership changes materially if, for example, the investor requires an option pool to be created (or increased) \u201cbefore\u201d their investment.<\/p>\n Practical example: the impact of the option pool on \u201ceffective pre-money<\/em>\u201d<\/p>\n Assume:<\/p>\n Scenario 1 (pool created \u201cafter\u201d the investment):<\/strong> the pool dilutes everyone proportionally after the investor comes in. The takeaway is simple: when you negotiate pre-money<\/em>, you must also negotiate when and how<\/strong> the option pool is accounted for and which instruments are included in the \u201cfully diluted\u201d definition. Otherwise, two parties can \u201cagree\u201d on \u20ac8M\u2026 while not buying\/selling the same ownership percentage.<\/p>\n Post-money<\/em> valuation refers to the total value of the company after receiving the investment.<\/strong> This value includes both the pre-money<\/em> valuation and the new capital contributed by investors in the funding round. Put differently, post-money<\/em>reflects the company\u2019s value once the new capital has been added\u2014and it is this figure that is used to calculate the ownership percentage each new shareholder will hold.<\/p>\n Post-money<\/em> is the value of the company after incorporating the new capital. The core formula is:<\/p>\n Post-money = Pre-money + Investment<\/strong><\/p>\n Post-money<\/em> is the figure that allows you to directly compute the new investor\u2019s ownership percentage (if there are no other adjustments):<\/p>\n % investor = Investment \/ Post-money<\/strong><\/p>\n Example:<\/p>\n The most common \u201ctrap\u201d is calculating the percentage on the pre-money<\/em>: the frequent mistake is to assume the investor owns 50% by contributing 50 into 100. That ignores the fact that new capital increases the company\u2019s total value and, therefore, the correct denominator for the final ownership percentage is the post-money<\/em> valuation.<\/p>\n In real-world rounds, final ownership may not be so linear because several elements come into play:<\/p>\n A particularly useful point to prevent surprises: in SAFEs, the market shifted toward post-money<\/strong> forms because they make it more transparent how much ownership is being sold (especially when multiple SAFEs are issued). Even so, raising \u201ctoo much\u201d SAFE capital at low caps can lead to more cumulative dilution than founders intuitively expect.<\/p>\n An aggressive pre-money<\/em> valuation may \u201csell less equity\u201d today, but it also creates an implicit requirement: the startup must grow enough to justify a subsequent round at a higher price. If it does not, a down round<\/strong> can occur, typically with two effects:<\/p>\n Conceptually, anti-dilution can be:<\/strong><\/p>\n There is no need to go into formulas in an introductory article, but the key message is: valuation is not only \u201chow much it\u2019s worth,\u201d but also what happens if market conditions change.<\/p>\n Understanding dilution\u2014and the difference between pre-money<\/em> and post-money<\/em> valuation\u2014is not only crucial for accurately calculating ownership stakes, but also for properly managing founder and shareholder dilution across successive funding rounds.<\/strong> A correct understanding of these concepts is essential to avoid common mistakes, enable successful negotiations, and ensure all parties involved have realistic expectations about value and ownership after an initial (or subsequent) funding round.<\/p>\n The difference between a healthy round and a problematic one often lies in the \u201cdetails\u201d that sit behind the numbers: fully diluted definitions, option pools, convertibles, and protection mechanisms in adverse scenarios.<\/p>\n Rules of thumb:<\/strong><\/p>\n In Spain, Ley 28\/2022<\/em> (the Startup Law)<\/strong> has reinforced the use of incentives (especially to attract talent through equity) and introduced a certification framework to access benefits, which makes it even more advisable to professionalize funding-round planning and capital structure.<\/p>\n If you are considering raising capital<\/a> through one (or multiple) funding rounds or a capital increase, or if you need financial advisory<\/a> support, Maraz Corporate Finance can help.<\/strong><\/p>\nWhat is pre-money<\/em> valuation?<\/h2>\n
