Conclusion

According to the above two graphs, our business will be able to come "break-even point" in the first 14 months. However, as mentioned in the assumption section, we did not take into account our salaries. The fact that our business takes 14 months to break-even without the salary suggest it will be difficult to succeed. 

When we were modeling our sales, we assumed we will acquire 6525 users which includes 1842 subscribers to the premium model. This is equivalent to 28.2% of the users. We felt this way because we believe that our premium model, which only includes GPS service is not very attractive to our customers. For our business to succeed, we need to make this premium model more attractive to customers, such as including capabilities to upload and organize files in the cloud.
