Introducing the Zero to One Guide: your tactical roadmap to raising your first check and getting your startup off the ground.
At Graham & Walker, we have spent the past eight years supporting early-stage founders. Many are raising their first check, figuring out how to pitch, and wondering if venture capital is even the right path. It can be confusing, overwhelming, and high stakes all at once.
The Zero to One Guide is a multi-part series to help you navigate it all. From deciding whether to raise VC to building your deck, crafting your ask, and scaling your business, we break it down with practical advice and real talk.
This is Part 1: Should You Raise Venture Capital?
Not every startup needs to raise venture capital. And that can be a strength.
We start every Founder Day by giving founders permission to ask themselves a really big question: is VC right for you and your startup? Venture capital is one way to build a business, but it’s not the only way. It is a path that shapes your goals, your timeline, and your day-to-day reality as a founder. You should know what that means before you go for it. This post is here to help you figure out if that path is right for you.
Power Laws Drive VC Behavior
Venture returns follow a power law. In other words, a small number of investments generate nearly all the returns. That is why investors care so much about size of outcome. A company that returns two or three times the investment may be a win for the founder. But it does not move the needle for a fund that needs a ten or one hundred times return.
This is the math behind venture capital. It explains why the bar is so high and why your vision needs to match that ambition.
What Makes a Company Venture Backable?
Venture capitalists are in the business of backing extreme outliers. Their model depends on a few companies returning the majority of the fund. To be considered venture backable, your startup needs to show that:
- The market opportunity is big enough to reach at least $100M in revenue in a specific category within a relatively short period of time
- Your business model can scale efficiently, not just grow
- There is a believable large outcome like an acquisition or IPO
- You are committed for the long haul and willing to take big swings
VCs are not just looking for good businesses, they are looking for massive breakout potential.
The question is not just whether you can raise VC. It is whether you should.
Calculating Your Market Size
If you are raising venture capital, investors will want to understand your market size. Not just in theory, but in real dollars. And not someday, but soon.
The most common framework for thinking about market size includes three layers:
Total Addressable Market (TAM): This is the total annual revenue opportunity available for your product or service. It represents the broadest view of your market. You can calculate it from the top down using industry research, or from the bottom up by estimating how many potential customers exist and how much each one would spend annually. Your TAM should reflect actual customer spend, be grounded in logic, and be specific enough to be credible.
Serviceable Available Market (SAM): This is the portion of your TAM that your business can realistically reach. It reflects the segment of customers you could serve based on your current product, pricing, and positioning.
Serviceable Obtainable Market (SOM): This is the share of SAM that you believe you can capture in the near term, given your team, resources, and go-to-market approach. It should be the most conservative and realistic estimate.
A few key reminders:
• Market size should be based on annual spend, not one-time purchases
• Your market must be specific to your solution and the problem you are solving
• If your market does not yet exist, estimate based on the number of potential customers and what you believe they would pay
Your calculation does not need to be perfect. But it should be intellectually honest, directionally correct, and aligned with the scale of your vision. Investors will ask how you got there. Make sure your logic is clear, your assumptions are reasonable, and your math reflects your ambition
Growth Versus Scale
Growth = adding revenue over time.
Scale = doing it in a way that becomes more efficient as you go.
If each new customer costs the same to acquire as the last one, you are growing. If your costs go down as you grow and your margins improve, you are scaling.
Venture capital is for companies that scale.
What an Exit Really Means
When you raise venture capital, your investors expect a return. That return usually comes from an acquisition or an IPO. If you want to build a profitable company that grows at your own pace, that is absolutely valid. But, that is not the venture model.
The venture path expects a liquidity event. Understanding that early helps you stay aligned with your long-term goals.
Final Takeaway: Is Venture Capital Right for You?
Before you raise, ask yourself not just whether you can, but whether you should.
Venture capital can be a powerful tool, but it comes with real tradeoffs. It is not for everyone, and it is not meant to be. Taking VC means committing to a path that will shape your company (and your role as a founder) for years to come.
You are signing up for a journey that could take a decade or more. This will not be your family business. The goal is to grow quickly and eventually exit, through an acquisition or IPO. You will be accountable to a board. You will be responsible to your investors. And yes, in some cases, they could decide to replace you as CEO.
That might sound intense. It is. But the best way to protect yourself is to pick your investors carefully. Look for alignment. Look for people who share your values and your vision. (More on that in a future post.)
Venture capital is not a badge of honor. It is a strategic decision. Choose it because it fits the kind of business you want to build and the kind of founder you want to become.
If you do choose this path, know that we are here to support you every step of the way, with clarity, conviction, and community.
