How Vertical AI is Making Legacy SaaS Obsolete: Key Data

What is vertical AI? The artificial intelligence landscape is experiencing a shift. While horizontal AI solutions continue to make headlines, a more targeted approach—vertical AI—is quietly revolutionizing how enterprises create and capture value using AI. Growing as fast as 400% year-over-year, vertical AI represents a fundamental reimagining of how organizations can leverage artificial intelligence for industry-specific transformation. With vertical SaaS companies already on the rise, incorporating AI in vertical offerings is natural and offers a significant growth opportunity for savvy companies.

‍

For starters, let’s clarify some key terms:

‍

• Traditional SaaS (Software as a Service): General-purpose tools that can be applied across multiple industries—Salesforce or Microsoft Office.
• Horizontal AI: Broad artificial intelligence platforms designed for universal applications, like ChatGPT or Google's Bard. They can perform various general tasks but need deep industry expertise.
• Vertical AI: AI solutions purpose-built for specific industries, combining deep domain knowledge with AI capabilities. These solutions are trained on industry-specific data, understand sector-specific terminology and regulations, and are optimized for particular business processes.

Consider Prophia, a vertical AI solution revolutionizing commercial real estate. Unlike traditional SaaS platforms that offer generic document processing or horizontal AI solutions that struggle with industry terminology, Prophia was purpose-built for the real estate sector (CRE). The system was developed and trained on approximately 100,000 proprietary CRE documents, enabling it to recognize and interpret over 200 commercial real estate terms in standard leases. This specialized training allows Prophia to deliver significantly higher accuracy in lease abstraction and critical date reporting.

‍

The contrast between approaches becomes even starker when examining resource efficiency. Horizontal AI solutions often require extensive computational power to interpret specialized real estate data with general-purpose algorithms; Prophia's optimized approach enables faster processing times for industry-specific operations. This efficiency extends to customization and compliance—traditional solutions require extensive modifications, but Prophia was built from the ground up with real estate data privacy requirements in mind.

Across industries, vertical AI is rapidly exceeding traditional software Total Addressable Markets (TAMs) by making previously unprofitable segments viable and creating entirely new revenue opportunities. According to Greylock Partners, investing in vertical AI means trading market size for “deeper market penetration.” It follows that vertical AI approaches parallel a host of industry-specific benefits, but also notable benefits across sectors—like an eight-times cheaper customer acquisition cost compared to horizontal competitors. of For enterprises, the opportunity is sizeable.

Below, we’ll discuss how enterprises can identify and execute a vertical AI strategy through a simple five-phase approach.

‍

Phase 1: Strategic Assessment of Workflows and Required Data

‍

The journey toward vertical AI implementation begins with a methodical assessment of opportunities and capabilities. This process requires a fundamental shift in how organizations evaluate technology investments. Rather than focusing solely on general process automation or broad efficiency gains, successful vertical AI implementations start with deep industry-specific analysis.

Luminance Legal exemplifies this approach in the legal sector. Their path to helping users achieve as much as 90% in time savings through AI-powered contract review began with a comprehensive analysis of existing workflows. They first mapped out every step of the contract review process, identifying not just time spent but also error rates, compliance risks, and opportunity costs. This granular understanding enabled them to build a business case that went beyond simple cost reduction to encompass quality improvements and risk mitigation.

With Luminance, major international law firms like Bird & Bird have realized incredible results. Luminance enabled Bird & Bird to review close to 200,000 documents pertaining to 20,000 employees in three weeks. Previously, the firm was only able to manually review 10% of documents in the same time span.

The assessment phase must also include a thorough evaluation of data resources and requirements. Success depends heavily on access to industry-specific data sets that can train specialized models. Organizations need to inventory their proprietary data assets, identify gaps in their data infrastructure, and develop strategies for acquiring or generating the additional data needed to train effective solutions.

Furthermore, the strategic assessment must consider the full scope of integration requirements. Unlike horizontal AI solutions that often operate as standalone tools, vertical AI needs to be deeply embedded within industry-specific workflows. This requires mapping out all touchpoints with existing systems, identifying potential bottlenecks, and developing a clear understanding of how the AI solution will enhance rather than disrupt established processes.

‍

Phase 2: Technical Foundation Building

‍

The technical architecture of vertical AI represents a fundamental departure from traditional AI development approaches. Sangeet Paul Choudary—a business executive, advisor, and bestselling author—emphasizes this point: "The advantage that vertical AI players have is that they operate full-stack—which is to say they provide a fully integrated solution across the interface, proprietary models, and proprietary data." This full-stack approach requires organizations to think differently about building and deploying AI solutions.

PathAI's success in healthcare diagnostics illustrates the efficacy of this specialized approach. According to PathAI, 90% of the top 15 biopharma companies use their technology—getting to that point wasn't simply a matter of applying general-purpose machine learning to medical images. Instead, they developed a comprehensive technical foundation that included specialized data collection protocols, custom model architectures explicitly designed for medical imaging, and integration pathways that worked seamlessly with existing healthcare systems and workflows.

The data strategy must be particularly sophisticated. Organizations need to develop mechanisms for collecting and curating industry-specific training data that captures the nuances of their sector. This often involves creating new data collection processes, establishing quality control mechanisms, and developing systems for continuous data refinement based on real-world performance. Additional requirements include robust APIs, clear data governance protocols, and mechanisms for seamless interaction between the AI system and existing enterprise software.

‍

Phase 3: Pilot Program Development for Vertical AI Applications

‍

The transition from strategy to execution requires a carefully structured pilot program that can demonstrate value while managing risk.

AlphaSense, a market intelligence and search platform, grew from its initial concept to a $100 million+ ARR business. The platform is used by major companies globally like 3M’s Global Strategy & Market Development team for synthesizing information and faster insights; Siemens’ Market Intelligence team for sifting through relevant Google alerts and Wall Street insights; and Salesforce’s Competitive Intelligence team.

But Alpha Sense’s pilot program began with a carefully selected group of 50 financial institutions, chosen not just for their potential as customers but also for their ability to provide detailed feedback and help refine the solution.

The success of pilot programs depends heavily on choosing the right initial use case. This selection process must balance multiple factors: the potential for demonstrable ROI, technical feasibility, data availability, and the ability to generate quick wins to build momentum for broader adoption. AlphaSense initially focused on a specific pain point in financial research—the time-consuming process of analyzing earnings calls and financial documents. By narrowing their focus, they could demonstrate concrete value: analysts using their platform completed research tasks three times faster than traditional methods.

‍

Establishing robust feedback mechanisms proves crucial during the pilot phase. Unlike horizontal AI solutions that can rely on general usage metrics, vertical AI requires deep, industry-specific feedback loops utilizing specific KPIs. This means creating structured processes for gathering input from subject matter experts, tracking industry-specific performance metrics, and continuously refining both the AI models and the user experience based on real-world usage patterns.

‍

Phase 4: Revenue Model Design

‍

Vertical AI enables sophisticated monetization strategies that transcend traditional software pricing models.

The quick-service restaurant (QSR) sector provides a compelling example of this transformation, with some data boasting higher-than-human order accuracy and the ability to handle 90% of orders without human intervention, with fast food giants like Taco Bell, Carl’s Jr., and White Castle rolling out AI voice-ordering to hundreds of locations. Wendy’s—in partnership with Google—has seen 22-seconds-faster drive-thru times through the technology and is rolling it out to more locations. These successes resulted from the AI model's ability to understand and predict industry-specific customer behaviors (like when an order for a milkshake was intended to be a Wendy’s Frosty), make contextually relevant upsell suggestions, and optimize menu presentations based on historical ordering patterns.

The revenue potential extends beyond direct efficiency gains. These solutions can expand total addressable markets by making previously unprofitable customer segments viable. For instance, specialized AI solutions can automate complex tasks that once required expensive human expertise, making enterprise-grade capabilities accessible to mid-market customers. This market expansion effect compounds over time as AI systems become more sophisticated and can handle increasingly complex industry-specific tasks.

‍

Phase 5: Scale & Optimization

‍

Mayo Clinic's "AI factory" demonstrates a holistic approach to scaling vertical AI applications—Google Vertex AI suite is a foundational element. Rather than treating each AI implementation as a separate project, they've created an enterprise-wide innovation engine that has spawned over 200 projects since 2021. This factory model transforms traditional scaling challenges—like maintaining quality while increasing quantity—into systematic, repeatable processes that actually improve with scale.

PathAI's success in scaling vertical AI across the medical diagnostics sector offers important considerations for enterprising building a scalability roadmap. By focusing exclusively on pathology, PathAI has achieved remarkable accuracy rates while continuously expanding its reach through strategic partnerships with pharmaceutical companies, research institutions, and healthcare providers. Their approach proves that depth breeds scalability—the deeper the domain expertise, the more opportunities emerge for expansion within that vertical.

The company's scaling strategy hinges on three key innovations: a modular platform architecture that adapts to different types of cancer and pathology applications, standardized processes for data annotation and model validation, and seamless integration with existing laboratory systems. This architectural approach allows PathAI to scale both vertically (deeper into specific cancer types) and horizontally (across different pathology applications) while maintaining the specialized focus that gives vertical AI its advantage.

PathAI’s success demonstrates how regulatory compliance and scale can work harmoniously. Rather than treating FDA requirements as obstacles, they've built compliance into their core infrastructure, transforming regulatory adherence into a competitive advantage. Their platform incorporates continuous feedback from pathologists, creating a virtuous cycle where each deployment improves the overall system while maintaining strict medical standards.

Vertical AI Critical Success Factors & Pitfalls

‍

The implementation of vertical AI demands a unique combination of technical expertise and industry-specific knowledge. Organizations that successfully navigate this transformation typically excel in several critical areas. Deep industry expertise must be seamlessly integrated with AI capabilities—this goes beyond simply having both skill sets present in the organization. Success requires creating frameworks for continuous knowledge transfer between domain experts and AI developers, ensuring that industry insight is effectively captured in the AI systems.

Risk management becomes more complex in vertical AI implementations due to industry-specific regulatory requirements and compliance standards. Organizations must develop comprehensive governance frameworks that address general AI risks and sector-specific concerns. This might involve ensuring AI decisions align with medical privacy regulations and clinical guidelines in healthcare. In financial services, systems must demonstrate compliance with anti-money laundering regulations and financial reporting requirements.

Common pitfalls in implementation often stem from underestimating the complexity of industry-specific requirements. Organizations frequently need to allocate more data preparation and cleaning resources, particularly when dealing with industry-specific formats and terminology. Another common mistake involves inadequate attention to change management—vertical AI often requires significant changes to established industry practices, and resistance to these changes can derail implementation if not properly managed.

Future Outlook & Next Steps

‍

The future of enterprise AI is increasingly vertical, with industry-specific solutions poised to deliver unprecedented value across sectors. Organizations must approach this transformation with a clear roadmap that balances quick wins with long-term strategic objectives.

Resource allocation during this transformation requires careful attention to industry-specific needs. Organizations must balance investments in technical infrastructure with spending on domain expertise and change management. This often means creating new roles bridging the gap between AI capabilities and industry knowledge, developing specialized training programs, and establishing centers of excellence that drive continuous innovation.

Organizations that successfully develop and deploy industry-specific AI solutions stand to capture disproportionate value in their markets. Those who need to move quickly risk being left behind as competitors leverage vertical AI to transform industry dynamics and capture new revenue opportunities.
