The Venture CodexSeed and Series A describe financing rounds; they do not provide a universal test of whether a company is ready to raise. A useful preparation question at either stage is: what evidence makes the proposed future credible, what remains uncertain, and what will the next investment enable?
Y Combinator's introductory fundraising guide describes the traditional sequence of seed followed by Series A, while explaining that companies do not have to follow every step. Its terminology provides background, rather than a set of current fundraising benchmarks. A Guide to Seed Fundraising
Why round labels only tell part of the story
Aaron Harris argues that founders should be cautious about treating a company's round label as a proxy for its maturity. In his current Preamble, he distinguishes uncertain venture bets from growth financing supported by a more established operating model. The founder and the case for the company's future remain central to his framework.
That does not make evidence optional. It means the evidence needs to be interpreted in the context of the business, its history and the opportunity being claimed.
Compare the questions you need to answer
The following is a preparation worksheet, not an eligibility checklist or a description of every investor's requirements:
| Question | Useful early-stage preparation | Useful preparation after an earlier raise |
|---|---|---|
| What do you understand? | Explain the customer problem and your distinctive insight | Show what experience has confirmed or changed |
| What have you demonstrated? | Present the strongest relevant evidence available | Explain progress since the previous financing |
| What remains difficult? | Name the most important unresolved assumptions | Show which risks remain and what you have learned about them |
| Why this team? | Connect experience and judgment to the opportunity | Include decisions and execution the team can now demonstrate |
| What does the money enable? | Identify the next meaningful outcome | Explain why the next plan is justified by what you have learned |
A later round gives you more history to explain. It does not make your story self-evident or remove the need for an investor who understands the opportunity.
Use metrics to support the case you are making
Harris's Why Metrics Still Matter argues for understanding and presenting the business accurately, rather than treating a headline number as a fundraising trigger. Explain definitions, show the relevant history and be able to discuss what changed.
Choose evidence that addresses the important uncertainty in your own business. A technical product might need a convincing demonstration against a customer requirement. A commercial product might need evidence that people continue to use or pay for it. Explain why that evidence matters to the opportunity you are describing.
Use this working evidence sheet:
| Claim you want an investor to believe | Evidence | What it does not yet establish | Next test |
|---|---|---|---|
| The problem matters | Customer observations or buying behaviour | Whether demand extends beyond the initial group | State the next research question |
| The product delivers value | Relevant usage, results or technical tests | Whether the result holds across more conditions | Define another test |
| The business can expand | Observed distribution or commercial progress | Whether expansion is repeatable | Identify the next constraint |

Explain the meaning of the numbers
Consider an illustrative example: monthly revenue grows from 10,000 to 20,000 in the reporting currency. That is 100% growth. The same percentage also describes a change from 100,000 to 200,000. The percentage alone leaves out the starting point.
Now ask what drove the change. Was it a new customer, wider adoption among existing customers, a price change or something else? What evidence supports that explanation? Those are useful preparation questions even when the growth rate is already calculated correctly.
Put the claim, calculation and supporting record together. Mark assumptions as assumptions, and prepare to explain gaps. This exercise helps you connect the business you describe with evidence someone else can inspect.
Make the next round's purpose explicit
Write a short plan covering the next outcome you want to achieve, the work required and the resources it needs. Then explain what success would demonstrate about the company.
This applies Harris's central question in The Only Reason to Raise Venture Capital: whether access to capital is what limits the business's next growth opportunity.
Finally, practice explaining why the opportunity matters. In How to pitch really damn well, Harris emphasises the importance of a coherent, honest account of the future you are building. Your evidence and your narrative should support the same case.
Do you need a particular revenue figure for Series A?
There is no universal revenue figure established by the round's name. Harris explicitly challenges fixed fundraising thresholds in When to Raise. Use conversations with relevant investors to understand how they evaluate your company, while keeping your own evidence and financing plan clear.
