What is the most efficient way for customer developmet?

Question

Startups

Good afternoon!
We are currently working on creating a mobile application. According to the Lean methodology, it is necessary to first carry out high-quality Customer Development in order to determine what a person needs.
What methods are most effective? So far, we have only created a Google questionnaire, and we are distributing it over the network.
We are making an application for selecting the cheapest taxi ride. We analyze Uber, Yandex Taxi, Gett.
They didn’t make a landing, but they made a bot in the @TaxigramBot telegram. From it you can understand how the service will work.

We also made another questionnaire, we throw it to friends, acquaintances, in various publics and groups. However, the minus here is that a very narrow demographic has turned out - the age of 90% is under 25 years old.
Yes, btw, it's not difficult for anyone, take 3 minutes for the questionnaire.goo.gl/forms/nmqyght44P
And can you write how well it is composed?
What else can you advise to identify user preferences?

Answer 1

You won't find much anyway. You need to launch the service in any minimal form, and then actively focus on A / B testing of features. So it is much more accurate to understand what you like, what you don’t. All sorts of focus groups are a thing of the past, since real users of the service will be completely different.

Answer 2

The Google questionnaire is only as accurate as you can get useful information from it. To extract it, you need to understand what you do not know and ask the right question.
For example, I already see a working mvp in the screenshot - a reference for prices. What do you miss in it and what do you want to know?

Answer 3

In small towns, the application is not promising. For the spread of prices between 90 rubles and 100 rubles is not significant. Another issue is convenience. If your application is convenient for solving the problem of finding a local taxi, then super.
For example, a case: you come to any city, turn on your favorite application and see everyone who is ready to take you and the amount of money for how much. And by selecting several taxi companies in your favorites, they will always be in the first lines for a specific search query.
Add here voice control in the same arbitrary style as in the telegram bot and now you are already a universal navigator with additional functions.
Make a call to local taxi parks with one button in the list of prices and now you have already solved the issue of finding contacts. If it is possible to send a request without a call, please indicate this separately, for this you can make a modular button with different states. For example, "Order" and "Order | [call icon]"
It is more important for you to understand that there is a market for such applications, and if you are adequately better in something, this market will gradually fill you with users from other similar applications. It is important to make a difference in terms of convenience and comfort of use, and then advertising will do its job.
