While horizontal SaaS platforms like Slack or Salesforce serve broad audiences, a new wave of vertical SaaS companies is quietly dominating highly specific industries. From practice management software for dental clinics to inventory systems built exclusively for craft breweries, these niche players win by going deep rather than wide. As highlighted at https://andrewlinksmith.com , vertical SaaS businesses often achieve remarkably high net revenue retention because their customers have very few credible alternatives, making switching costs naturally high. Their products speak the language of the industry, comply with sector-specific regulations, and solve problems that generic tools simply cannot address.
