With ever-expanding choices and unprecedented adoption rates, SaaS AI is probably one of the most volatile business technology markets. Clarity is needed more than ever for businesses to make the right choice.
This is the only regularly-updated report tracking the most popular SaaS AI tools by global adoption, plus breakdowns of key AI market trends and spending patterns.
Average AI spend for businesses has increased more than 150% in the last 6 months. But 9 in every 10 contracts are above price benchmarks, often by as much as 22%, due to a lack of data, negotiation skills and industry knowledge.
The Top 25 rankings are rapidly changing, with some vendors climbing or dropping as much as 15 places in the last 6 months.
Vendors are charging higher fees for embedded AI capabilties - raising subscription costs by as much as 100%.
The data and analysis in this report is drawn from the largest global dataset of pricing benchmarks and intel - covering:
We’ve placed the most widely-adopted AI tools into two distinct categories:
AI-Native - Standalone products where the user experience is entirely around interacting with AI (e.g. OpenAI and Glean).
Applied AI - Paid-for AI capabilities added to an established SaaS tool (e.g. Salesforce's "Einstein" or Google's "Gemini").
This distinction is important because, while they are both being heavily invested in by global businesses, their adoptions rates are very different. This indicates an initial difference in spending choices, popularity and corporate AI strategies.

Key trends
Top end stability: The top four companies are largely unchanged, suggesting a strong foothold in adoption with relatively accepted use cases, while competition and experimentation are concentrated elsewhere.
Turbulent AI-Native market: The extreme volatility in the rest of the AI-Native rankings highlights how frequently new players are entering and making headway quickly.
Dominance of platforms over niche tools: Broad, general-purpose AI tools dominate the rankings, most notably OpenAI, Sana Labs and Glean Technologies. This may reflect companies' appetite for rapid AI transformation across multiple departments, and a preference for custom tools and functionality.
Notable absentees: While many might expect tools such as Perplexity, Otter.ai and Poe to feature in these leaderboards, these are far more popular with consumers than businesses.
A new AI feature isn’t enough to encourage switching: Stability among the Applied AI vendors suggests their AI capabilities are seen as enhancements, not primary purchase drivers. The complexity and cost of switching appears to override the benefit of new AI capabilities.
Average increase in AI spending since Dec'24

Corporate spending on AI is surging - almost 300% growth year-on-year for AI-Native platforms.
But there are differences in the direction of adoption. 12 months ago the split for spending between AI-Native and Applied AI applications was almost equal. Now it's 2.4 : 1 in favour of AI-Native, indicating where the market's preference lies.
"AI-native tools let organisations place smaller, faster bets. Lower entry costs and cleaner contracts make it easier to test real use cases, walk away when value isn't there and prove a business case early, which is a huge strategic advantage in an uncertain market."
And the slower rate of spend in Applied AI is perhaps understandable. Over 60% of enterprise SaaS products now include Applied AI, and 73% of these also charge an "AI premium" for these additions, sometimes increasing subscription costs by up to 100% - which may well be forcing businesses to investigate alternative AI-native point solutions to save costs.
AI spend increase (as a % of total software spend)

AI tools now account for 3.75% of all software spend - more than double its 1.64% share in just June 2025.
Vertice data shows that IT is the highest-spending industry on AI tools - spending 7.5x the cross-industry average. Financial Services (4.3x) and Healthcare & Life Sciences (1.5x) make up the top three biggest spenders.
Although, there is a clear lag among larger enterprise companies. They adopt tools only half as rapidly as SMBs, and at less than a third of the pace of mid-market companies.

This is likely due to stricter compliance policies, higher risk management barriers and more complex business cases.
However, this overall surge in spending is threatening to spiral out of control.
Overspend on AI (%)

Across all industries and SaaS categories, when current SaaS contracts are compared to Vertice data and pricing benchmarks, it shows that 90% of agreed prices are needlessly above benchmarks.
And in the case of AI specifically, AI-Native software buyers are overspending by an average of 22% due to lack of vendor pricing data and a structured negotiation strategy.
To avoid overspending on AI:
Leverage peer benchmarking data to determine what similar companies are paying for the same subscription.
Strategically negotiate contracts, using a combination of vendor benchmarks, usage data, and market insights to secure the best terms.
Protect future spend: Negotiate contract clauses such as removing auto-renewal provisions and including caps on price uplifts, limits on overage charges, performance guarantees, and exit or migration terms.
