Selling AI versus selling SaaS

Why the difference is not technical, but systemic

There is a growing tendency to describe almost any modern software product as “AI”. From a commercial perspective, this is understandable. From a go-to-market perspective, it is often misleading.

The reason is not that AI is categorically different technology, but that once a product crosses a certain threshold, the logic by which it creates value changes, and with that, the logic by which it must be sold.

Most of the friction we currently see in AI commercialisation does not come from immature models or missing features, but from applying SaaS assumptions to systems that no longer behave like SaaS.

Where value is created: the defining distinction

A useful way to frame the difference between selling SaaS and selling AI is to ask where value is actually created.

In classic SaaS, value creation remains firmly with the human user. The software provides structure, efficiency, visibility, or coordination, but the outcome depends on human execution. A CRM enables a salesperson, but does not sell. A recruitment platform enables a recruiter, but does not hire. Even advanced analytics tools surface insights, but leave interpretation and action to the user.

This is not a limitation of SaaS; it is its defining characteristic. SaaS scales human work.

Truly Native-AI starts to behave differently once it no longer merely supports human decision-making, but performs the task itself. At that point, value creation shifts away from the user and towards the system. The human role changes from executor to supervisor, validator, or exception handler.

This is a qualitative change. It is not about doing the same work faster, but about changing the locus of responsibility.

Once the system owns the outcome, it no longer makes sense to think in terms of “helping users be more effective”. The relevant question becomes whether the existing human-centric system is even the right design in the first place.

Many processes that rely on constant attention, anomaly detection, verification, or large-scale pattern recognition are not failing because people are bad at their jobs, but because the system is structurally misaligned with human constraints such as attention span, fatigue, and cognitive load. In those cases, replacing the human with an AI is not an optimisation; it is a correction.

From tool thinking to system thinking

Despite this, many AI products continue to be positioned as tools. The messaging focuses on how the product makes a specific role more effective, rather than questioning whether that role should exist in its current form at all.

This creates a disconnect. The product is effectively proposing a system change, while the positioning suggests incremental improvement.

Once an AI system starts owning a process end to end, it should be understood as a system, not a tool. That distinction matters because tools are adopted bottom up, while systems are introduced top down. Tools compete on features and usability; systems compete on outcomes and reliability. The AI has agency is the process, it becomes agentic (definition below).

Failing to make that shift explicit leads to confusion inside the buyer organisation about what is actually being adopted and why.

Agentic AI and ownership of outcomes

Much of the current discussion around “agentic AI” becomes clearer when framed this way. Agentic AI is not primarily about autonomy in a technical sense, but about ownership of outcomes.

A helpful mental model is a matrix with two axes. On one axis, horizontal versus vertical AI. Horizontal AI operates across domains and contexts; vertical AI is trained on domain-specific data and knowledge. On the other axis, assistive versus agentic AI. Assistive AI supports human work; agentic AI owns a result.

The commercially most challenging category sits in the quadrant of agentic vertical AI. These systems operate within a narrowly defined domain, rely on specific datasets, and are expected to deliver a defined outcome without continuous human intervention.

Once you operate in this quadrant, you are no longer selling “software with AI”. You are selling the replacement of a process.

1) Why selling AI requires deeper process knowledge than selling SaaS

This shift has direct implications for sales.

In SaaS sales, strong product knowledge, a reasonable understanding of the competitive landscape, and sufficient domain context to surface pain points are often enough. The seller’s role is to help the buyer recognise that a tool can improve how they work.

In AI sales, that logic breaks down. If you are proposing that a system should take over a process entirely, you need a deep understanding of how that process currently operates, where it fails, and how it should ideally be designed.

This does not mean the seller needs to outperform domain experts across the board. It does mean they need to be able to reason at a system level within the specific scope the AI is addressing. Otherwise, claims about replacing human work remain abstract, unconvincing and to be frank - amateur-like.

There is also a credibility aspect. Arguing that certain tasks should no longer be performed by humans is a strong, politically charged claim. Making that claim without demonstrating deep technical and process insight undermines trust immediately.

2) Testability: from trials to proof of value

The difference in value creation also affects how products are evaluated.

SaaS products are typically tested through trials & pilots. Users explore the tool and assess whether it improves their day-to-day work. The evaluation is experiential.

Agentic AI cannot be evaluated in the same way. You are not asking users whether they like the interface; you are asking the organisation to trust a system with responsibility for outcomes.

As a result, AI commercialisation often requires a two-step approach. First, a proof of value that compares the performance of the existing human-driven system with the AI-driven system. This establishes whether there is a demonstrable delta. Only once that delta is clear does it make sense to move towards piloting and scaling.

The evaluation criterion is not usability, but system performance.

3) Organisational politics and buyer dynamics

Another consequence of system replacement is that the buying dynamics change.

SaaS tools typically benefit the people who use them. These users often act as internal champions, supported by their managers. Adoption is aligned with personal incentives.

Agentic AI often disrupts this alignment. If a system absorbs tasks or replaces roles, it can reduce team size, scope, or influence. In those cases, the people most affected by adoption are not the ones who will benefit directly from it.

As a result, the decision tends to move up the organisation, towards people who are accountable for outcomes rather than tasks. CFOs, COOs, and functional executives become more relevant than individual contributors or team leads.

This shift is frequently underestimated. Many AI go-to-market motions start with the same user-centric approach as SaaS, only to stall when organisational resistance emerges later in the process.

Selling AI means becoming much more comfortable to speak to senior stakeholders from the get-go. Rather than relying on bottom-up motions.

4) Implications for sales structure and roles

These dynamics also affect how sales teams should be structured.

SaaS organisations often rely on relatively generalist account executives, supported by sales engineers as needed. Volume and repeatability are key.

In AI selling, especially for agentic vertical systems, technical credibility and process understanding carry more weight. In some cases, the sales engineer or domain expert becomes the primary trust builder, with the commercial role focusing more on orchestration than persuasion.

The ratios between sales and technical roles often shift accordingly.

5) Channels and the role of partners

There is also a channel implication. Because AI adoption can be politically sensitive, especially when it implies workforce reduction or fundamental process change, vendor-provided proof is often insufficient on its own.

This creates space for partners who can act as a vendor-agnostic voice, similar to the role management consultants have historically played. Their function is not just technical validation, but also political buffering. They take responsibility for stating that an existing process is inefficient and needs to change.

For AI vendors, partnering with such actors can reduce friction, particularly in later-stage or enterprise contexts.

6) Pricing as a reflection of accountability

Pricing provides another lens into how a product is positioned.

Seat-based or usage-based pricing implies that value is still created by humans using the system. Outcome-based pricing implies that the system owns performance and carries part of the risk.

Outcome-based pricing only works if the vendor controls the critical parts of the value chain. If the last mile remains outside of the system’s control, accountability becomes blurred. In some cases, this pushes AI companies towards more integrated, less “pure software” models, where control over execution becomes a competitive advantage rather than a scalability concern.

A more appropriate analogy than SaaS

To understand the challenges of selling AI, it helps to look at other industries to identify patterns. As such, historically, a better analogy for selling agentic AI is not SaaS, but integrated suppliers in industrial value chains.

The key difference is not software versus hardware. It is ownership of a critical function.

In SaaS, the vendor provides a tool that can usually be swapped with limited systemic consequences. In contrast, an integrated supplier provides a component that becomes part of the customer’s operating system. Once that component is in place, switching suppliers is no longer a commercial decision alone. It becomes an operational risk decision.

That is exactly what happens when AI owns outcomes.

Component ownership versus tool usage

In a traditional SaaS relationship, the customer owns the process and the outcome. The vendor owns the tool. If the tool disappoints, the customer can often replace it without redesigning how the organisation works.

With integrated suppliers, this logic flips.

A supplier that owns a braking system, a power module, or a control unit does not just deliver a product. It delivers a guaranteed behaviour inside a larger machine. The OEM no longer reasons in terms of “features”, but in terms of reliability, predictability, and failure modes.

Agentic AI behaves the same way once it replaces a human-led process. The customer is no longer buying functionality. They are delegating responsibility for a specific part of their system.

That delegation is what makes the decision heavier.

Why switching becomes hard, even if alternatives exist

One of the defining characteristics of integrated suppliers is status quo bias. OEMs are notoriously reluctant to switch suppliers, even when alternatives are cheaper or technically superior.

This is often misinterpreted as conservatism or lack of innovation. In reality, it is rational.

Switching an integrated supplier means:

• revalidating assumptions about performance

• re-testing edge cases and failure modes

• retraining internal teams

• accepting unknown risks

The cost of failure is asymmetric. A small improvement rarely justifies introducing new uncertainty.

The same dynamic applies to AI systems that are deeply embedded into processes. Once an AI system owns anomaly detection, forecasting, optimisation, or verification end to end, replacing it is no longer a simple procurement exercise. It requires re-establishing trust in an entirely new system.

This is why incumbent advantage becomes extreme once AI systems are embedded.

Why proof of value looks like supplier qualification

When OEMs qualify suppliers, they do not run “trials” in the SaaS sense. They run validation programs.

They compare:

• expected versus actual performance

• behaviour under stress

• consistency over time

This is structurally similar to how AI systems should be evaluated. Proof of value is not about showing that the AI works in principle. It is about demonstrating that the AI performs reliably within the customer’s specific system constraints.

Seen through this lens, long pilots and staged rollouts are not inefficiencies. They are risk management.

Why the buyer changes in supplier-style selling

Integrated suppliers rarely sell to end users. They sell to people who are accountable for system-level outcomes.

An engineer may influence the decision. A plant manager or operations executive makes it.

AI follows the same pattern. Once the system replaces a process, the buyer shifts away from the people performing the work toward those accountable for throughput, cost, risk, and reliability.

This is one of the most common mismatches in AI go-to-market strategies: starting with user-centric messaging when the decision logic is system-centric.

The strategic implication

If you accept the supplier analogy, several things become clearer:

• AI adoption is closer to infrastructure decisions than software purchases

• Trust, predictability, and risk dominate feature discussions

• Sales cycles lengthen not because buyers are slow, but because they are rational

• Pricing, sales roles, and partnerships need to reflect this increased responsibility

Seen this way, many AI go-to-market problems are not execution issues. They are category errors. Teams are selling components as if they were tools.

Closing thought

Selling AI, when understood as selling systems that own outcomes, is not an incremental evolution of SaaS selling. It requires different assumptions about value creation, testing, buyers, pricing, and organisational impact.

Treating AI as “SaaS with smarter features” may be sufficient in early conversations, but it obscures the real challenges that determine whether these systems can be adopted at scale.

Those challenges are not technical. They are systemic.
