The SaaS market is growing 18% yearly and will hit $720 billion by 2028. But PwC research shows 73% of SaaS startups fail because they can’t keep users around.

Three key factors that make or break success:

1. Usability

It directly hits your bottom line. Forrester Research proves it: improve UX by 10% and conversions jump 200%. When users aren’t stuck figuring out your interface, they actually get stuff done. The payoff? More engagement and people willing to pay for premium features.

2. Personalization

McKinsey found that SaaS products with smart interfaces have 41% lower churn rates. When your system remembers user preferences, shows relevant data, and gives helpful hints — users see real value. They feel invested because they’ve customized things, so they’re way less likely to jump ship to competitors.

3. Consistency

UserTesting discovered something interesting: SaaS companies with solid design systems get 67% fewer support requests. When your interface works the same way from your landing page to mobile app, users can find what they need without help.

Good design means users figure out what to do in 30 seconds, don’t hunt for buttons, and keep coming back because your product helps instead of frustrates them. Wyzowl and IBM data backs this up: 86% of users stay with intuitive products, and every UX dollar invested pays back big time. Design isn’t about looking pretty — it’s about staying competitive and making steady money.
