As AI speeds up content production and digital ads become easier to “wear out,” the big question for marketers is no longer whether to test creatively, but how to maintain a continuous testing rhythm without bloating headcount. For B2C brands in Vietnam, this is a very real issue, as ad costs can rise quickly if old creative assets saturate too fast.
MarTech’s article shows that the solution is not to hire a lot more people, but to reorganize flexible capacity: use contractors/freelancers as an extension of the team, standardize briefs to reduce friction, and measure testing effectiveness with clear business metrics.
Why creative testing is becoming a “speed race”
MarTech describes a familiar loop in performance marketing: ads get creative fatigue, distribution platforms demand fresh assets, and if ideas are not fed in time, customer acquisition costs rise. This is especially true in social and mobile environments, where users scroll quickly and expect to keep seeing new content.
The problem is that today’s content consumption speed no longer allows in-house teams to work at the old pace. A product launch campaign, day-to-day website operations, and other recurring tasks are already enough to drain an internal creative team’s capacity. As a result, many brands know they need to test more, but simply do not have the bandwidth to do it.
This is the “velocity trap” MarTech refers to: if you do not speed up creation, ad performance declines; but if you rely only on fixed staff, costs and operational pressure balloon.
Freelancers as the “stretchy pants” of the marketing team
To illustrate a flexible model, the article uses a very everyday image: a pair of stretchy pants that can expand when you need to eat more and then return to normal. In marketing, freelancers and short-term contractors play a similar role — helping the team temporarily scale up during heavy testing periods, then scale back down when demand eases.
What stands out is that MarTech does not see freelancers as people who simply “do extra work.” They can become a specialized resource, especially during periods that require high speed and new skills, including the ability to work with generative AI tools such as Midjourney, Claude or Firefly. In other words, brands do not necessarily need to keep these skills on full-time payroll, but they can still activate them when needed for short sprints.
This approach helps the in-house team remain central to strategy, while external resources handle capacity expansion and rapid variant creation.
To make it work, operational friction must come down first
MarTech notes that many brands are hesitant to use freelancers because they have run into very “everyday” barriers: slow administrative processes, lengthy onboarding, output that does not match the brand voice, or poor coordination with the internal team. If these bottlenecks are not addressed, the flexible model will be hard to scale.
The proposed solution is to build a pre-vetted “talent bench.” In other words, the company does not wait until it needs someone to start looking, but proactively signs and readies a diverse group of creators from the outset. When signs of creative fatigue appear, the marketing team can assign work to an external designer or copywriter in a very short time, instead of waiting through a lengthy hiring process.
On the operations side, using freelancer management software integrated with project management tools will help trigger work quickly by ticket, while keeping the working status clear between all parties.
Standardize briefs so AI and freelancers stay on brand
Another key point is input quality. Both freelancers and AI tools need clear direction; otherwise, they can easily produce off-brand content, the wrong message, or even violate industry standards. According to MarTech, the gap between “knowing what you want” and “expressing it clearly enough for others or AI to do it right” is exactly what makes the review process drag on.
Rather than relying on a massive brand book, the article suggests moving to modular briefs: keep core rules such as fonts, color palettes, and visual boundaries tightly defined and store them in a digital asset management (DAM) system. From there, each task assigned to a freelancer or AI should be a specific slice, for example writing three headline variations for one audience segment instead of asking them to develop an entire campaign from scratch.
This way of breaking down work is especially useful when marketers want to test many variants quickly while still maintaining tight brand control.
Measure testing effectiveness with business metrics, not gut feel
MarTech also emphasizes that the case for finance leaders should not revolve around “more people” but around “more growth opportunities.” When performance marketing can be measured by clicks, bounce rate, position, orders, or other conversion signals, businesses have a basis for evaluating which variable costs are worth investing in.
Instead of debating the cost per creative asset, the article suggests reframing the discussion around the cost of missed opportunities. A major campaign built on untested creative can burn through budget very quickly if performance is weak. Meanwhile, setting aside part of the budget for test variants supported by freelancers can help identify winning approaches sooner and improve ROI.
More importantly, this model allows the core team to focus on long-term brand goals, while the flexible group handles short-term performance sprints.
What this means for the Vietnamese market
For Vietnamese businesses, especially in retail, e-commerce, consumer finance, and F&B, the article’s message is clear: in a period when AI is accelerating content production, the advantage no longer lies in how many people are on payroll, but in the ability to design a flexible, controlled content-creation ecosystem.
In reality, many local marketing teams are still using the same approach for both branding and performance, which leaves internal teams overloaded and pushes creative testing to the bottom of the priority list. If they can build a trusted freelancer network, standardize briefs, and set up clear evaluation processes from the start, brands can test faster without increasing headcount with every campaign cycle.
In other words, instead of asking “should we hire more people?”, Vietnamese marketers should ask “which work should stay in-house, and which can be expanded flexibly outside the team to keep testing moving at a steady pace?”
