Before You Hire Anyone to Build Your SaaS Do This First

The instinct when you have a SaaS idea is to find a developer as quickly as possible. The idea is clear in your head. The problem is real. The solution makes sense. Why wait?

The reason to wait is that hiring a developer before you can answer four specific questions costs more money and produces worse results than hiring one after you can. Not because developers are untrustworthy. Because the cost of changing direction after code has been written is many times the cost of changing direction before it has.

The Four Things You Need to Know First

What does done look like for version one? Not the full product vision. Just version one. What is the smallest version of this product that proves the idea works and delivers genuine value to the first users? If you cannot describe this in a way that two people would agree on, your developer cannot build it reliably either. The scope of version one is the most important thing you can define before any developer conversations.

What technical decisions have long-term consequences? Some technical choices are easy to change later. Others are extremely expensive to reverse. The choice of database, the authentication approach, the way user roles are structured, the architecture that determines what you can build next, these are not decisions to leave entirely to a developer you have not yet hired. You do not need to make them yourself, but you need to understand that they exist and ask about them explicitly.

What does the first user do in the product? Not the full set of possible user journeys. The primary thing, the core workflow that makes the product valuable. Can you describe it step by step? User opens the product. They do this. Then this. Then this. They get this result. This description is the first thing your developer should build, and it should be clear enough that you could check whether they built it correctly.

What is in scope and what is not? Scope definition before development starts is the single biggest predictor of whether the project comes in near the budget and timeline you planned. Not because developers are trying to pad scope, but because unclear requirements are interpreted differently by different people, and the difference between what you meant and what your developer understood only becomes visible when something is already built.

What to Do With These Answers

Once you can answer these four questions, you are ready to have a useful conversation with a developer or technical team. You can explain what you want to build. You can evaluate whether they understand it. You can compare quotes across different developers because the scope is defined well enough that each quote is responding to the same thing.

More importantly, you can evaluate the quality of the questions they ask you. A developer or technical team worth working with will push back on your answers. They will ask you what happens when a user does something unexpected. They will ask whether feature X is actually needed in version one or whether you have assumed it is. They will ask about edge cases you have not considered. The quality of their questions tells you more about the quality of their work than any portfolio.

The Step Most Founders Skip

Between having clear answers to the four questions and hiring a developer, there is a step most non-technical founders skip: getting a second technical opinion on what you are planning to build before any code is written.

This does not have to be a full discovery sprint. It can be a two-hour conversation with a senior developer who is not being hired to build the product. Ask them to look at what you are planning and tell you what concerns them. Which decisions have long-term consequences you should understand? What would they do differently and why? What have you not thought about that will matter later?

The information from that conversation is almost always worth more than the cost of the conversation. You will hear one thing you had not considered that changes how you approach the entire project. That change, made before development starts, is free. Made after three months of development, it is very expensive.

Forgex Systems (forgex.systems) offers discovery sprints for exactly this purpose. Two weeks before any code is written, we work through the architecture, the scope, the assumptions, and the decisions with long-term consequences, and produce a roadmap that any developer can build from. The founders who come to us after a bad build almost always describe a moment early in the project where, if they had had a senior technical opinion, they would have done something differently.
