Synopsis

Most founders start the “how much to raise” question with a dollar figure instead of a goal. This guide flips that order, starting with the milestone you need to hit next, working out what it actually costs to get there, and showing why both under-raising and over-raising can quietly hurt a startup down the line.

The first, obviously harder question is how much they need. But once a founder decides that outside money is in order the second (and even harder) question follows hard on its heels: how much? If you ask five different investors, you’ll probably receive five different answers; from “raise as much as you can for as long as you're willing to give it away” to “raise the minimum and keep it lean”. Neither of those bits of advice is bad, and both may lead a founder down the wrong path if they don’t think about their context first.

The correct right number is not a formula that can be extracted from a spreadsheet template. Work backwards from what you have to show next on a schedule, then build enough buffer to survive the unexpected. This is how you should think about it.

Start With What You Need to Prove, not what you want

Starting with a dollar figure, rather than a goal is the most common mistake founders make. Seed rounds are “around two to four million dollars right now,” and therefore companies anchor to that number instead of asking what their business needs to accomplish to either raise again or become profitable.

A good starting point is to name the one or two conditions that must be fulfilled when this money runs out. This could be a specific number of paid users, demonstrating product-market fit in another vertical, achieving some level of revenue that would justify a Series A discussion, or even something as basic as having an actual working version of the product to present to real users. Whatever that is, it should be something that the investors in your next round or a lender or even your future self will look at and say. That is real progress, not just activity.

Determining the size of the round will be a much easier question once that milestone is clear: How much time and money does it take to get from here to there?

Convert The Milestone Into A Runway Number

Once you have defined the milestone, the next step is to calculate how much time it will 6effectively take to reach it, in turn determining what expense will be incurred up to that point, in order to maintain business continuity. Founders usually underestimate on both counts here. When creating a budget on a spreadsheet instead of living it from month to month, things almost invariably take longer than anticipated and costs sneak up in ways that are easy not to see.

This is a messy but straightforward way of approaching it: Take the time between the present and your projected window in which you would hit the milestone, multiply by your monthly burn rate (the amount a business spends per month that has no revenue coming in), then add a margin on top of that. Without an extreme need to overly optimise for every dollar, most seasoned founders and investors usually recommend adding three to six months of additional runway on top of your best guess, as the fundraising process itself takes time (typically somewhere between three and six months from first conversation through money in the bank) and you don’t want to be running out of capital during that process.

But if your true valuation is fourteen months to get you to the milestone, raise twenty, or even eighteen months. That cushion isn’t fluff for the sake of fluff, it’s what keeps you from having to go back to investors listening with your tail between your legs.

Realise When You Go Low

Doing less feels prudent, more disciplined, and sometimes it is. But this carries a very real risk, one that too many founders do not factor into their thinking: running out of money before you have proven enough to be successfully pushed through the next funding round.

If that happens, you need to be back in fundraising mode sooner than you had hoped, often with less leverage than last time. Investors can tell when a founder is raising out of need instead of strength, which ends up in bad terms with bad valuations or just absolutely zero interest. In the worst-case scenarios, it brings them to a down round with where they raise money at a lower valuation than ever before, which can be soul-crushing to the team and activate anti-dilution clauses that punish existing investors and founders alike.

Asking for just a tad less than you need seldom saves you money in the long run. All it does is shift the difficult discussion, and usually in a more challenging context.

Know What Will Happen If You Go Overboard

The opposite error, however, is a lot more alluring but virtually never seems to be discussed. If you raise more than you need, it seems like a win at the time, extra runway, an extra safety net, and fewer fundraising headaches for a while. The expense shows up later, in three different ways.

First, dilution. Each dollar raised comes at the opportunity cost of a jacket spray broadcast ownership, and unnecessary dollars cause unacceptable dilution for inventors and early customers. Second, an overly exuberant valuation assumes a target against which you need to perform by the next round. When you raise again, if the business hasn’t progressed to that valuation you’re looking at a down round - one of the things raising conservatively is meant to render moot.

The third one is the most underrated in my opinion: having too much money removes the discipline (unless you are starving at a gut level) for that young company. This can be more pronounced when teams have room in the buffer because there is no squeeze to force a focus clubs tend to hire ahead of need delaying hard decisions or chasing too many ideas at once. It is said that a constrained sum of money, fenced round an objective, focuses the mind, not loosens it.

The Number Should Follow Valuation, Not Lead It

The opposite is the case: valuation and raise size are linked, and they should not be set in that order. One common trap is to choose what round size first, and then back into the dilution number until a valuation feels good. It generates a valuation which is rarely related to the concrete value of, nor the stage of, the business and seasoned investors see through it in double-quick time.

The more measured approach is to allow your milestone and the calculation of your runway to determine the amount you plan to raise then have a frank discussion with potential investors about what valuation band makes sense given both your traction, market and comps. If it's painful, that’s an indication that you either extend your runway number based on a smaller raise or wait longer until more traction before staying up in later-stage rounds and forcing a bigger valuation to make the maths pencil out.

Milestones over fixed runway goals

Others default to a round number of “we’ll raise enough for 18 months” without anchoring that to something the business needs to accomplish that time. That seems a reasonable starting point, but should be pressure-tested against the milestone-based approach described previously. As such, a runway with no specific goal tied to it can quietly become eighteen months of activity, and not the same as. When you tie the raise to a milestone, with a runway calculated around it, you keep the target grounded in something that a future investor will care about.

Bringing It Together

How much to raise isn’t about choosing the biggest number you can think of, or the one that sounds the least dangerous. An honest estimate of how long and how much your next round has to be true, times the buffer that is sometimes nicknamed “What if it takes us a year instead,” and also adds a very real buffer since things do not usually go at all as planned. Hit that calculation, and the conversation around your valuations, dilution and timing of your next round becomes as simple as the subheading of this paragraph.
