Every industry has its own software — roofing, dental, property management, legal, solar, HVAC, recruiting, restaurants. These products charge $200-$2,000/month. Most haven't been meaningfully updated in years. None were built with AI. Every one of them is a business you could build, operate, and sell.
Horizontal SaaS (Salesforce, HubSpot, Monday) tries to serve everyone. Vertical SaaS is purpose-built for a specific industry — it speaks the language, follows the workflow, and solves the exact problems that generic tools can't.

Most vertical SaaS products were founded 10-20 years ago. They're CRUD applications with bolted-on AI. Their users spend half their day updating the software instead of doing their job.
Fitness/wellness scheduling. 24 years old. Added "AI" in 2024 — auto-reminders and no-show prediction. The core is still a booking calendar.
Property management. 22 years old. Acquired by RealPage. Tenant portal still looks like 2015. No AI capabilities. Manual everything.
Property management. Public company. Added "AI leasing assistant" in 2023 — a chatbot. Core platform unchanged for years.
Inventory and order management. 19 years old. Still desktop-first with a web add-on. No AI. No automation beyond basic alerts.
Legal practice management. Market leader. Added "Clio Duo" AI in 2024 — document drafting. 16 years of accumulated technical debt underneath.
Field service. $9.5B valuation. "Titan Intelligence" added 2023 — call transcription. Users report steep learning curve and high cost. $1,000+/mo.
Every vertical SaaS product reinvents the same wheel. Authentication, payments, email, help desk, deployment, documentation. They build it from scratch, maintain it alone, and pass the cost to customers. These aren't differentiators — they're table stakes.
Not just the software. The company operations, the documentation, the help desk, the infrastructure, and the AI that runs it. Delivered in weeks, not months.
