Choosing the right first investors for a SaaS company
How a founder can judge investor fit for a first SaaS company - the criteria worth writing down, questions to ask, and what to check before accepting money.
This article is general education written by World Enterprise Editorial. It is not legal or financial advice. Nothing in it recommends any investor, and World Enterprise makes no promise that any investor will fund any company. Choosing whom to approach is your decision, made with your own advisers.
Founders who are ready to take outside money often treat every investor as interchangeable: money is money. In practice, the people who put money into your company become part of its story for years. They hold a stake, receive your updates, sometimes have rights over future decisions and form opinions about you that travel. This article is about judging fit, so that if you choose to approach investors, you decide whom to approach and why. It is about your judgment, whether or not you also use our paid Investor Introductions add-on, which is described below.
Start with what you need, not who is available
Before you look at any investor, write down what you need from the money and from the person providing it. Paul Graham’s essay “How to Fund a Startup” argues for choosing investors on quality and alignment rather than on prestige, and it describes startups moving through funding sources in sequence, each round providing enough runway to reach the next stage. The essay was written in 2005 and the funding landscape has changed since, so use it for its reasoning rather than its details.
A useful written brief has four parts:
- The purpose of the money. What will it allow the company to do that it cannot do now? State it as evidence you intend to produce, such as customers acquired or a product milestone reached.
- The amount and the plan it supports. A figure derived from your own plan, with the reasoning shown. Do not copy a number from another company.
- The kind of help you want. Customers, hiring, product judgment, a second opinion, or just capital.
- The terms you will not accept. Agreed in advance with your counsel.
If you cannot write this brief, you are not ready to evaluate investors, since you will not know what you are evaluating them against.
Criteria worth writing down
Each of the criteria below is an editorial suggestion. Weigh them for your situation and add your own.
| Criterion | What to ask yourself | How to find evidence |
|---|---|---|
| Stage fit | Does this investor typically back companies at my stage? | Their public statements, published criteria and previously announced backing |
| Category fit | Do they understand software businesses like mine, and my customers? | The questions they ask, their public writing, what they say about your category |
| Size fit | Is the amount they usually commit in line with what I need? | Their published guidance, or ask directly |
| Founder fit | Would I want to work with this person when things go badly? | Conversations with founders they backed, chosen by you, not only those they suggest |
| Behavior under stress | How do they act when a plan slips? | Ask founders about a hard moment, not a good one |
| Process | Do they decide quickly and say no clearly? | Their own description and reports from others |
| Terms | Are their terms ordinary for the instrument, and clearly explained? | Your counsel’s review |
| Follow-on | Do they say plainly what they will and will not do in later rounds? | Ask directly and get it in writing where possible |
Be wary of using a single signal, such as a famous name, as a substitute for the others. The essay cautions that the interests of an investor and a founder are not identical, and that alignment is worth checking rather than assuming.
Research from public information
You can learn a good deal without any introduction at all. Look at what an investor has published: their written criteria, their public statements about what they look for and the companies they have publicly announced backing. Read these as an investor’s own account and treat them as claims to check, not facts. Where an investor publishes something about how they work, compare it with the stories of founders you can reach on your own.
Keep the research in a simple tracker: the investor, the source of each fact, the date you read it and your assessment against your criteria. Dates matter, because what an investor says they want changes.
How investors tend to be reached
Investor Introductions is a separate, paid add-on, and nothing else in our program depends on it. Whether or not you use it, expect to do much of the approaching yourself, through your own network, your own outreach and public channels. Paul Graham’s essay observes that personal connections matter and cold submissions rarely succeed; whether that is still true in your market is something to test, not assume. Whatever route you use, be accurate about your company, and be careful about what you say regarding an offering. The SEC explains on its exempt offerings page that securities offerings must register or rely on an exemption, and that some routes limit how an offering can be promoted. Ask your counsel what you may say, to whom, and how, before you start.
Questions to ask an investor
You are choosing too. A good conversation includes questions from your side.
- What do you look for in a company at my stage, and what would make you decline?
- How do you usually work with founders after committing? How often do you want updates, and in what form?
- What has been the hardest situation you have shared with a founder, and how did it go?
- What do you expect of the board or of decisions, if anything?
- What do you usually do in later rounds? Do you reserve capital for follow-on?
- What happens if I need to change the plan?
- Which of your founders might I speak to, including some who have had a hard time?
- How long do you take to decide, and what steps come before an answer?
Listen for specifics. Vague answers are information.
Understand the instrument before the investor
The investor you choose will come with a form of agreement. Y Combinator’s page describes a SAFE as a short contract an investor signs to fund a startup now in exchange for the right to shares later, and notes that anyone using the forms should consult a lawyer licensed in the country where the company was formed. Other instruments exist, and each affects ownership and later decisions differently. Whichever one is on the table, have your counsel explain it using your own ownership table before you sign, and ask for a worked example.
Signals worth taking seriously
- An investor who will not explain their terms in plain language.
- Pressure to decide quickly without time for counsel.
- Reluctance to let you talk to founders they have backed.
- Requests for rights that do not fit your stage, or that you do not understand.
- Founders you trust who say, privately, that they would not work with this investor again.
None of these is proof of anything, but each is a reason to slow down and ask questions.
Keep a relationship in good order
Once someone has committed, the relationship runs on communication. A regular, accurate, short update builds trust and reduces ad hoc requests. Our weekly update template in the library gives you a starting format. Report bad news early. A company that tells its investors the truth about a missed plan has more options than one that conceals it.
What this article does not know
We cannot tell you which investor is right for your company, whether any investor will be interested or how any conversation will go. We have not used statistics about investor behavior, because we have no public primary source we can apply to your situation. The essay we cite reflects one author’s view, written in 2005. World Enterprise makes no promise of funding or of any investor meeting; this article exists to help you judge fit with your own eyes.
