The impact of vibe coding on martech is already emerging from vendor churn and changing purchasing behavior. Mid-market firms have seen a 35% year-over-year decline in the renewal of one-way martech tools, according to Chiefmartec & MartechTribe’s “Martech for 2026 Report.”
Chris Penn, co-founder and chief data officer at TrustInsights.ai, says the issue goes deeper than cost or efficiency.
“The biggest challenge, on a large scale, is that vibe coding is not just about ‘is your code right?’ because most are not. Most people’s codes aren’t either, and that’s okay. But the challenge is a few things. First, it makes the software a complete asset,” he said.
Those sales are already changing who builds the software. About 63% of Vibe Coding users are not developers, according to Superframeworks’ “Vibe Coding Tipping Point 2026” report, which means that marketers themselves are increasingly creating the tools they are buying.
Point solutions are under pressure
The shift is most visible at the edges of the stack, where point solutions once filled gaps but are now easier to recreate internally at lower cost.
“The stack grows into layers with different competitive physics,” Scott Brinker wrote on his blog last week. “Native AI tools win big in creativity. Copy ideas, pitch decks, visual production, competitive intelligence. Jobs where the main input is content and type, and where the quality of the model is the product.”
Established SaaS platforms like HubSpot and Salesforce still dominate the orchestration layer, according to Brinker. They handle integrated tasks like lead scoring, routing, pipeline management, channelization, and personalization, where data is linked directly to action within systems like CRMs, marketing automation platforms, and ecommerce tools.
Risks in the martech industry
“And obviously that creates risks, especially in the martech industry, because you’ve got what, a gazillion martech vendors?” Penn said. “Well, now you have a gazillion martech vendors and a bunch of people saying, ‘I can do that too, and I don’t have to pay anything,'” he said.
That shift turns substitution into elimination, as some classes disappear entirely from the stacks rather than being replaced by others.
In some cases, the shift is dramatic enough to reset entire stacks. Penn points to one agency that replaced most of its software systems with built-in tools.

Replacement gives way to removal
“I was talking to someone this morning, they work at a sales agency, and their agency replaced 80% of their subscription software. Out the window, they just put in their code,” he said. “They saved a lot of money, and those SaaS companies are now out of luck.”
Extensive adoption data supports that trend, with 92% of US developers using AI coding tools on a daily basis, according to Hashnode’s “The State of Vibe Coding in 2026,” and 41% of all code now generated by AI globally, based on 13Labs’ “Vibe Coding Report 2026.”
That combination of power and discovery accelerates how quickly teams can change or remove tools.
As more teams build their own tools, feature-based segmentation becomes harder to support across vendors. Products that once felt unique are becoming increasingly interchangeable in the eyes of consumers.
The difference is folding
Penn highlights how quickly software can be replicated. “There’s nothing that this new company is offering that you can’t literally replicate in a day… You already have a large amount of software now that’s almost identical.”
This creates a new decision point for marketers: choose between similar vendors or build their own solution.
Not all parts of the stack are equally exposed to this change, especially systems of record like CRM. These platforms remain stable due to the switching costs associated with data, training, and operations.
Penn describes the restriction in practical terms.
“Their core CRM has like 15 years of data in there, and moving that data is a pain … and training the people who use it …
Business systems are still there, for now
This creates a fragmented market where core systems remain stuck while external tools become easier to replace or remove.
As the software itself becomes easier to replicate, the source of value moves from features to areas that are difficult to replicate.
“There’s no such thing as making it secure when you’re trying to secure software. Software isn’t secure anymore,” Penn said.
Instead, differentiation comes from what surrounds the product. “Where you will make a noticeable difference is in the price chain,” he said. “Your customer support, your service, your care, what value added on top of the product is hard to replicate?”

A different kind of martech evolution
A broader shift is toward design rather than procurement, especially workflows that can be recreated quickly and cheaply. This coincides with the rapid growth of vibe coding platforms, which have reached a market worth 18 billion dollars, according to IdeaPlan’s “2026 SaaS Market Trends.”
For marketers, this creates more flexibility and cost control, while introducing new responsibilities in terms of maintenance and administration. For retailers, it raises the bar to stay relevant in the increasingly customizable stack.
The result is a martech environment where fewer tools are bought, more are built and the real competition is beyond the software itself.
