Background:
We have zero marketing experience. We are a startup focusing on car maintenance/ marketplace for mechanics/services.
We are about to launch our app and the aim is to generate significant traction to help us close our angel round and allow us to iterate our product.
Our target users: 20-34, female drivers and new drivers, car enthusiasts.
The feedback from beta testers is that "Word of Mouth" will be the most effective way of convincing them to download the app.
We have not raised any investment capital so we have almost no money to spend on marketing etc.
Hi! This is a very ambitious question! Good for you but you weren't as targeted/realistic as you should be asking the question.
Growth hacking is not magic, it works but not over night and not specifically for a set number of users or conversions.
Ultimately what you want is number of users daily rather than downloads. Even if your app was for sale and all you care is downloads if your app is not good or provides no incentive for daily use your sales will dwindle off after that initial spark.
A good growth strategist will take his or her time in evaluating the UX of your app, flow, customer acquisition, trends online, craft personas, measure bounce rate your apps landing page, etc, then work out a plan to get you exposed just to the right group of people and providing them with set of tools for easy conversion.
I hope that helps in helping you understand how GH works a bit so that you can maybe craft some ideas on your own and have an idea on how to get started in your own targeted marketing tactics, because at the end of the day that's what growth hacking is...
