How to Validate a Business Idea Before You Dive into Entrepreneurship

Having a good idea is not enough. For a project to succeed, it’s crucial to know whether that idea can be turned into a real, profitable business model. At Adlanter, we support entrepreneurs every step of the way—and validating the idea is one of the most decisive.

If you’ve already read our 50 Business Ideas for 2025, the next step is clear: check if your idea holds up beyond the drawing board.

Here’s how to do it, step by step.

1. Clearly define the problem you solve

Every business idea starts with a need. No problem means no solution to sell. Ask yourself:

• What specific need am I addressing?
• Who is most affected by this problem?
• How is it currently solved and why is my solution better?

This approach helps you focus your value proposition and understand if there’s real demand. Also, when you start defining the products or services you’ll offer, it’s essential to comply with certain legal requirements to ensure that the information you provide is clear and transparent.

According to Article 45 of the Consumer and User Statute Law, you must ensure that consumers receive “truthful, effective, correct, sufficient, understandable and transparent” information about the products or services you offer.

2. Know your potential customer

It’s not enough to imagine who you’ll sell to. You need to talk to that person. Design a clear profile of your ideal customer (some call it a buyer persona or, in the case of talent, a candidate person), and validate the following:

• Do they have the problem you’re solving?
• Are they willing to pay to solve it?
• How do they make purchasing decisions?

Short interviews, surveys, or test groups are effective tools at this stage. It’s also important to consider personal data protection throughout this process, as established by Article 1 of the Organic Law on Data Protection. To avoid setbacks, make sure to inform participants about how their data will be used and obtain their informed consent.

3. Study the market and your competition

Conduct a basic but rigorous market analysis:

• How big is the market?
• Is it growing, stagnant, or declining?
• Who are your direct and indirect competitors?
• What can you do differently or better?

This analysis not only validates your idea but also sharpens your value proposition.

4. Launch a minimum test (MVP)

Don’t wait until everything is perfect. Create a basic version of your product or service that allows you to test the idea with minimal cost. It can be:

• A website with a form to gauge interest
• A pilot service with a few clients
• A functional prototype of your product

According to Article 17 of the Consumer and User Statute Law of Navarra, companies must ensure maximum transparency in business relationships. During the Minimum Viable Product (MVP) phase, it’s essential to clearly communicate that this is a trial version, inform users of the service or product conditions, and avoid creating misleading expectations.

5. Measure, learn, and adjust

Use objective data to assess whether your idea works:

• How many people showed interest?
• How many would pay for it?
• What direct feedback did you receive?

This is where your adaptability comes into play. Sometimes, it’s not the idea that needs to change—but the approach.

6. What if my idea doesn’t work?

Validation also means knowing when to stop. If the data and market indicate there’s no opportunity, don’t see it as a failure—the real failure is not validating and moving forward blindly. Every validation brings you closer to a solid and profitable proposal.
