# The minimum CRO team: one person and a platform that does the rest > Traditional CRO needs an analyst, a designer, a developer and a statistician.

It's that the standard job description requires four people they don't have. Look at what a conventional experiment actually consumes: an analyst to find the opportunity, a designer to draw the variant, a developer to build it, and someone numerate enough to decide whether the result means anything. At a company of eight, those four roles are one person who also runs the paid accounts. So the useful question isn't "how do we hire a CRO team?". It's "which of those four jobs genuinely needs a human here?". ## The analyst job: partly automatable Finding where to look is pattern recognition over your own traffic: which pages have volume and poor conversion, which segments behave unlike the average, where the funnel leaks. None of that requires judgement about your business — it requires reading your data carefully and consistently, which software does better than a busy person. What does require a human is knowing which findings are actionable. "Users from organic convert 40% better than paid" is a true observation that might mean your ads are badly targeted, or that organic users are further down the funnel, or that your attribution is misconfigured. Software can surface the pattern; you supply the context. Bixlow reads your traffic and surfaces the segments where behaviour diverges from the baseline. It proposes; you decide whether the proposal describes a real problem or an artefact of how you buy media. ## The designer job: mostly not needed for testing This one is a category error rather than a resourcing problem. Most experiments don't need design work — they need a structural change to an existing page: moving a block, making something persistent, removing a step, changing an emphasis. You don't need a designer to test whether shipping information above the fold helps. You'd need one to redesign the page properly once you know it does. Design comes *after* the evidence, which is the opposite of how most teams sequence it. ## The developer job: this is the one that blocks everything Here's the real bottleneck at small brands. The idea exists, the decision is made, and then it sits for six weeks because the one technical person is shipping the actual product. This is the job that a platform can remove almost entirely. You describe the variant in plain language, Bixlow generates the workflow — selectors, conditions, variant behaviour, events — and you review a visual blueprint before anything goes live. When the generated selector is wrong because your theme names things oddly, you fix it in the editor rather than filing a ticket. Importantly, removing the developer from the critical path isn't removing engineering oversight. The generated code is visible, there's a staging environment to validate against, and a technical person can review what's about to publish in two minutes rather than build it in two days. ## The statistician job: must not be human, and must not be AI either This is the one people get wrong in the other direction. Sample sizes, significance, confidence intervals, guardrail monitoring, assignment and mutual exclusion — none of this should depend on a person's judgement in the moment, because the moment is exactly when motivated reasoning arrives. It also shouldn't depend on a language model. Assignment has to be deterministic, persistence has to be exact, and the statistics have to be the same numbers every time you look. Bixlow's engine is ordinary, strict, testable software for precisely this reason: the AI is the interface, not the arbiter. That separation matters more as the AI does more. The more decisions you let a model propose, the more important it is that the measurement underneath cannot be talked into a favourable answer. ## What the one person actually does Stripped down, the human job is: decide what's worth knowing, supply business context to the patterns, review the blueprint before publishing, and interpret what a result means for the company. That's a few hours a week, not a full-time role. It's also work that can't be delegated to software, because it's all judgement about your business rather than execution. ## Key takeaways - Of the four traditional CRO roles, only judgement about your business genuinely needs a human at a small brand. - Design should come after the evidence, not before it. Most experiments are structural, not visual. - The developer dependency is the real blocker, and it's the one a platform can remove without removing engineering oversight. - Statistics and assignment must be deterministic software — not human judgement in the moment, and not a language model. --- ## Meet our AI CRO agent What you just read, put to work by an agent: it understands your visitors, decides what to test or personalize, builds it on your site without a developer and tells you when a result is real. https://bixlow.com/en/ai-cro-agent
