After a sharp contraction in 2023, enterprise software investment rebounded in 2024. Venture funding climbed 7 percent over the previous year and reached $371 billion as mega‑rounds for AI‑native companies returned. Analysts at Sapphire Ventures noted that the year was marked by an AI‑driven rebound in VC funding and “ultra‑round” financings concentrated in AI research labs. In the last quarter alone, investors poured $113 billion into the sector. This capital surge signals that the AI SaaS market is healing, and it’s shifting attention to companies that embed AI deeply into operations rather than grafting it on as a feature. 


 

Why vertical SaaS is outpacing horizontal platforms 


Enterprise software once promised unlimited scale through one‑size‑fits‑all products, but this model is showing its limits. A 2024 study found that more than 40 percent of software companies are increasing specialization in existing industries and almost a third are expanding into new verticals. Vertical SaaS, software built for a specific industry, now outgrows horizontal enterprise software.  


While traditional enterprise software grew 11.1 percent in 2023 and is expected to compound around 9.6 percent through 2032, vertical SaaS is forecast to grow 12–15 percent annually through 2034. Customers increasingly demand tools that are preconfigured for industry‑specific workflows; firms with fewer than 50 employees juggle an average of 16 different SaaS apps, creating complexity that vertical solutions simplify. It’s no surprise that 89 percent of executives and IT leaders surveyed in 2023 said vertical SaaS “is the way of the future”. 


Several structural advantages drive this momentum: 

  1. Higher revenue and retention: Verticalization correlates with a 10–20 percent increase in year‑over‑year revenue growth for B2B companies. Platforms that embed payments and other fintech services often see 2–5x increases in revenue and retention. That makes sense because sector‑specific workflows enable natural cross‑sell and upsell opportunities, strengthening customer stickiness. 


  2. Lower customer‑acquisition costs: Research shows that vertical SaaS vendors maintain a sales‑and‑marketing (S&M) expense ratio around 17 percent of revenue, roughly half the 34 percent spent by horizontal vendors. Focused teams, industry‑specific marketing, and efficient product adoption reduce cost to acquire each customer. 


  3. Market penetration: Specialists trade addressable market size for market share. For example, Mindbody, a fitness management platform, controls 61.5 percent of its niche. Shopify powers 29 percent of ecommerce websites. Deep domain knowledge allows these players to become the operating system of their industry. 


  4. AI unlocking new niches: Andreessen Horowitz observed that there are already over 5 000 vertical SaaS companies in the US spanning industries from trucking to real estate. AI is widening the opportunity: by automating sales, marketing and back‑office labor, AI can increase revenue per customer by up to 10x, turning previously “too small” markets into large opportunities. The same report notes that more than 600 NAICS industries still lack modern vertical software. 


Ramp’s trajectory as evidence of the rebound 


Ramp illustrates how an AI‑first vertical platform can ride this recovery. Founded in 2019 as a corporate card for startups, Ramp has evolved into an AI‑native finance operating system. It automates expense policies, procurement workflows and compliance tasks using domain‑aware agents. The company’s metrics highlight both market recovery and the advantages of specialization:

Valuation and revenue data from company disclosures show a nearly four‑fold increase over two years. Customer count grew from about 15 000 in 2023 to more than 40 000 by mid‑2025. 


By early 2025 Ramp reached positive cash flow, a rare achievement for a late‑stage fintech, while still investing heavily in product development. The chart below visualizes Ramp’s valuation growth over this period. It illustrates how quickly an AI‑first vertical SaaS company can compound its value.

Ramp’s success is rooted in its AI‑first architecture. In beta tests, its finance agents processed 10 000 transactions while reducing manual reviews by 85 percent and detecting 15x more policy violations. Customers are achieving three times the productivity they had in 2023, and Ramp expects a 30x increase by 2027 through parallel agent operations. By embedding AI into core workflows rather than offering bolt‑on copilots, Ramp turns routine finance tasks into autonomous processes. This capability is precisely what many CFOs seek as they navigate a market where efficiency and compliance are paramount.

Trends shaping the AI‑SaaS landscape 


  1. Concentrated investment in AI‑native platforms. The 2024 rebound was driven by mega‑financings for AI labs and AI‑native software companies. Though deal count hit a 10‑year low, funding volume recovered, signalling that investors are prioritizing fewer, higher‑conviction bets. 

 

  1. Shift to verticalization and specialization. More than two‑fifths of software companies are doubling down on industry specialization, and analysts forecast vertical SaaS growth of 12–15 percent annually, well ahead of horizontal platforms. Customers want solutions configured for their regulatory environment, data models and workflows. 

 

  1. Integration of fintech and embedded payments. Embedded finance is becoming table stakes. Among vertical SaaS providers surveyed, nearly 40 percent already offer a fintech product, and those who integrate payments often experience 2–5× revenue lifts. Fintech not only drives revenue but also increases retention by making the software indispensable to daily operations. 

 

  1. AI as leverage, not garnish. AI is transforming vertical SaaS beyond chatbots. Andreessen Horowitz notes that AI can replace labor across sales, marketing, customer service and finance, expanding the revenue potential per customer by up to tenfold. It also reduces customer‑acquisition costs by automating outreach and support. 

 

  1. Market penetration and operational efficiency. Vertical SaaS vendors achieve higher penetration rates and lower churn. Some platforms command 50 percent or more of their market. Their sales and marketing spend is half that of generalist software, leading to better margins and faster payback periods. This structural efficiency appeals to investors seeking resilient growth. 


How to stand out in a competitive AI SaaS market 


The recovery in AI‑native SaaS is real, but it doesn’t lift all boats. Here are strategies for builders and investors looking to differentiate: 


  1. Choose a niche with high manual labor or regulatory complexity. Look for industries with repetitive tasks and unique compliance requirements. According to a16z, many markets such as laundry services, chiropractic offices and veterinary clinics, spend billions on labor each year but remain underserved by software. AI can capture this labor spend by automating back‑office workflows. 

 

  1. Embed AI in the workflow, not on top of it. Avoid generic copilots. Build agents that understand domain rules, data structures and approval hierarchies. Ramp’s success stems from embedding AI into expense policy enforcement and procurement, reducing manual touchpoints by 85 percent. 

 

  1. Build payment and lending rails. Integrated fintech deepens stickiness and opens new revenue streams. Embedded payment solutions have been shown to drive 2–5× increases in revenue and retention for vertical platforms. The Tidemark benchmark survey found that about 40 percent of vertical SaaS companies already offer fintech products, if your competitors don’t, you have a first‑mover advantage. 


  2. Leverage specialized data. Vertical platforms collect granular, proprietary datasets that can feed better AI models. High‑quality training data leads to more accurate predictions and automation. This becomes a moat that generic software cannot match. 


  3. Focus on customer success and support. In niche markets, reputation and word‑of‑mouth carry disproportionate weight. HiringThing’s report notes that impeccable service prevents churn and converts users into advocates. Invest in implementation, training and continuous education to ensure customers realize the value of your software. 


Conclusion: the future is vertical and AI‑native 


The AI‑SaaS market is recovering, but not uniformly. Investors are favouring companies that combine AI‑native architectures with deep vertical focus. Vertical SaaS platforms benefit from higher growth rates, lower go‑to‑market costs, and stronger customer retention than their horizontal peers. They embed payments and AI into the core workflow, creating compounding advantages. Ramp’s rapid ascent, from a $5.8 billion valuation in 2023 to $22.5 billion in 2025, illustrates how powerful this model can be. For builders and investors, the message is clear: pick a vertical, understand its workflows intimately, and architect the product around automation. The next generation of software winners will not be those who tack AI onto dashboards, but those who make AI the operating system of an industry.
