You've validated that customers have the problem you want to solve. But is the opportunity big enough to build a sustainable tech startup around?
Market sizing helps you understand whether enough users exist to make your venture worthwhile.
Engagement Message
Have you ever thought through a market size for a software idea?
Two approaches work for estimating market size: top-down (starting with large market data) and bottom-up (counting individual users you can realistically reach).
Bottom-up gives more accurate numbers for new tech startups.
Engagement Message
Which approach sounds more reliable for a productivity app: top-down or bottom-up?
Start with simple online research. Google your problem plus "market size," check tech industry reports, and browse software analysis sites like Statista or CB Insights. GitHub statistics and app store data provide user behavior insights.
Don't overthink this—rough estimates matter more than precision.
Engagement Message
What's one free online source you could use to research your potential software market?
For direct research, observe your target users where they already spend time online. This could be developer forums, product communities like Product Hunt, GitHub repositories, Reddit communities, or relevant software review sites.
These methods give you real-world data about user behavior and needs.
Engagement Message
Name one online community where you could observe potential users for your idea.
Calculate conservatively using this formula: identify total potential users, estimate what percentage you could realistically reach, then determine how many would actually convert to paying customers.
Most new tech startups capture 0.1-1% of their addressable market in year one.
Engagement Message
If 100,000 people have this problem and you capture 0.1–1%, roughly how many users is that?
