A landing page can be your first MVP
Before developing an application, find out whether your offer attracts interest and what questions customers ask.

Not every business needs to start with an application. If your main uncertainty is whether anyone needs your service, a landing page can present your offer and start conversations with potential customers.
Make the offer understandable
Explain who the service is for, the problem it solves and what happens after someone contacts you. Avoid promises you cannot yet fulfill. If the product is still being developed, say so. Do not present a waiting list as an available purchase.
Imagine a workshop considering a home maintenance service. Its first page could explain the areas it actually covers, the type of work and how to request an assessment. It does not need user accounts or a live map to learn whether people are interested.
Choose one main action
Use a call to action that matches your stage: request information, ask for a demonstration or voluntarily subscribe to updates. Only request the information you need. Every extra field creates effort and a responsibility to protect that information.
Plan the next step too. An unanswered request is a poor way to test an offer. Decide who will respond and record questions without promising a response time the team cannot maintain.
Measure with context
Look at requests, traffic sources and conversations. Low response can come from the wrong audience, unclear messaging or an unattractive offer. Statistics alone cannot tell you which explanation is correct.
Talk with interested people and look for patterns. Then decide whether to adjust the message, try another channel or build the next step of the service. A landing page is a learning tool, not automatic proof that the whole business will work.
