Why does Round Sizing matter?
The number is read as a statement about your judgment before it is read as a request. Too little and the round funds a period that ends before anything is provable, which sets up a raise from a weaker position than the one you are in now; too much and you are pricing in dilution and expectations your evidence does not yet support. Investors reverse-engineer the plan from the number, so an ask that does not correspond to a milestone tells them the plan does not exist.
What does Round Sizing look like in practice?
Suppose a team of four needs eighteen months to get from a working product to a repeatable sales motion, and burns roughly $120k a month once two salespeople are hired. Raising twelve months of runway funds the hiring but ends the round three months before the motion could be shown to repeat, the next raise then happens on the same evidence as this one. The honest version of the ask names the milestone, the months, and the burn that connects them, rather than a round number chosen because it sounds like a seed.
What are the common mistakes with Round Sizing?
- Picking the number first and building the plan backwards to justify it.
- Sizing to zero rather than to the start of the next raise. A raise takes months, and runway that ends the week the money runs out is runway you never get to use.
- Quoting a range so wide it reveals no plan. An investor reads "$2M to $5M" as two different companies.
- Ignoring what the round does to the cap table. The amount and the valuation together set dilution, and a sized-right round at the wrong price is still the wrong round.
