🧩 What Is Vertical SaaS?
Vertical SaaS is software built for a specific industry or niche, unlike horizontal SaaS (like Notion, Slack, or Zoom). It deeply solves domain-specific problems—think of it as “Salesforce, but just for dentists,” or “Freshbooks, but only for freelance architects.”
Now add AI? You don’t just automate tasks—you redefine workflows.
💡 Why Combine AI + Vertical SaaS in 2025?
- More focused = easier to acquire, retain, and monetize users
- AI allows you to replace entire roles, not just speed them up
- Industry-specific data unlocks more accurate AI results (think prompt tuning, RAG)
📊 VCs in 2025 are actively investing in vertical SaaS AI startups—because it’s easier to show repeatable revenue, strong retention, and defensibility.
