For startups there's plenty of options, mixpanel is probably my favorite.
Google Analytics probably has more users because of ease of use for small business but I wouldn't say it's a space without competition.
If a company is serious about learning about its customers and how they use their products, then it invests in Adobe Analytics.
If a company is looking for something that's free, quick, and "good enough," then it goes with Google Analytics.
Just like if a company is serious about advertising, it hires a professional ad agency. If it's looking for something cheap and "good enough," it go with Google AdWords.
- "Show me where my visitors are coming from"
- "Show me what landing pages are most popular... at driving conversion... by channel"
