How would you approach estimating the market size for a new mobile app in a specific geography?

During my final year at university, I worked on a project aimed at developing a mobile app for student engagement on campus. To estimate the market size, I first identified our target demographic—students aged 18-24. I researched enrollment statistics from the university and found there were around 20,000 students. Next, I conducted surveys to understand how many students would potentially use such an app, estimating that around 50% would be interested, giving us a target market of about 10,000 users. Additionally, I analyzed similar apps on campus and their download rates to refine our projections. This structured approach helped my team understand the potential reach of our app, allowing us to tailor our features accordingly.

In my volunteer role at a local nonprofit, I helped design a mobile app aimed at improving fundraising efforts. To estimate the market size, I examined the local population and identified key demographics that typically engage in charitable giving. I found that our city had approximately 500,000 residents, with around 20% actively involved in charity work. Conducting a few focus groups, we discovered that around 30% of those participants would likely use our app for donations. This led me to estimate about 30,000 potential users for our app in the local area. This experience taught me how to engage with community members and leverage their feedback for effective market size estimation.

In my first job as a marketing assistant at a tech startup, I was tasked with estimating the market size for a new app targeting remote workers. I began by analyzing industry reports and surveys that indicated there were around 50 million remote workers in the U.S. From there, I narrowed it down to our target audience—freelancers and small business owners. I researched existing market penetration rates for similar apps and estimated that about 10% could realistically be targeted, which led to a potential user base of approximately 5 million users. This experience taught me the importance of using a combination of qualitative and quantitative data to make informed market size predictions.
