Over the past few weeks, I’ve spoken with several entrepreneurs who are developing all-in-one, AI-powered vertical SaaS applications and making significant progress. In contrast, the previous generation of SaaS companies typically consisted of horizontal platforms that excelled in one market segment, such as marketing automation or sales engagement. These products were comprehensive, serving a wide range of industries. Over time, many of these applications moved upmarket, focusing on mid-market and enterprise clients.

In addition to horizontal players, numerous vertical SaaS applications have emerged over the last two decades. These typically followed a playbook of targeting small to midsize businesses in specific segments before gradually moving upmarket. They focused on delivering the most valuable features for their target audience while avoiding overly broad functionality.

With the rise of AI-powered software development, including low-code platforms and vibe coding, robust cloud computing resources, and mature open-source ecosystems, building large-scale software quickly has never been easier. As a result, entrepreneurs are now creating AI-powered vertical SaaS products that combine the functionality of multiple horizontal tools into a single, purpose-built solution for specific industries. Instead of small business owners needing separate tools for their website, social media, marketing automation, CRM, and sales engagement, a single system now provides everything they need, tailored to their vertical. These solutions are offered at a significantly lower price point with greater ease of use. Moreover, because these products are directly tied to revenue through lead generation, proposals, and new business, their ROI is clear.

My recommendation to entrepreneurs is to identify a vertical they or a colleague know intimately and consider building a comprehensive application that replaces multiple existing tools for that target customer. By leveraging AI, cloud infrastructure, and open-source technologies, they can deliver a fully integrated solution at a fraction of the cost.
