👋 Hi, it’s Rick Koleta. Welcome to GTM Vault - a breakdown of how high-growth companies design, test, and scale revenue architecture. Join 27,000+ operators building GTM systems that compound.This episode in the Library: the written playbook, the stack and the full transcript, free and open. Open it at pro.gtmvault.co.The ad shipped. The creative looked great. The campaign went live. Performance still stalled. Not because targeting failed, not because the budget was wrong. The team scaled ad volume faster than its ability to learn. The feedback loop between the ad account and the people making the ads never closed.George Howes built Magicbrief to close that loop. Before Magicbrief, George spent years inside top creative agencies watching the same failure repeat at every brand. Teams launched ads, collected results, and moved on. Learning never compounded. Magicbrief was the first attempt at a creative intelligence platform that ingested ad performance and pushed it back to the teams making the ads. It worked. Canva acquired the company. George now leads Canva Grow, the product Canva is building to make the loop operate at enterprise scale.Canva Grow ingests ad performance from every platform, ties each result back to the specific creative asset that produced the outcome, and pushes those learnings into the next round of creative before the next round of creative is made. The architectural premise is simple. Creative and media are not separate disciplines. They are the same system measured at different time scales. Every company that still treats them as two is losing compounding efficiency at every handoff.In GTM 45, George breaks down why most performance marketing failures are not media problems but feedback loop failures, why creative teams and data teams sit at opposite ends of a broken handoff, and what changes when the learning loop runs in days instead of quarters. He explains why AI is a multiplier for creative feedback and not a replacement for it, why click-through rate lies more often than any other metric in the stack, and why small teams with all context in one place consistently outperform large teams with fragmented tooling.This is not a conversation about better ad tools.It is a conversation about why creative and media are the same system, and what happens when you design the feedback loop between them as infrastructure instead of a monthly report.Inside this episodeThis episode maps the structural gap between how most performance marketing teams run today and what the feedback layer has to become when ad volume scales faster than learning, when AI compresses creative production to minutes, and when the buyer never sees the test matrix you ran.George starts with the pattern he kept seeing from agencies. The creative team and the data team never sat together. Creatives made the ads. Analysts read the ad manager. The handoff between those two functions was weekly meetings, slide decks, and aging context. The people responsible for the next round of creative were almost never the people looking at the dashboards that showed what the last round produced. The learning never landed. Agencies delivered work that was, by design, detached from the context that would have made it better.We go deep on why creative became the bottleneck, not spend or distribution. A decade ago, the constraint was production speed. Tools were expensive, crews were slow, iteration cycles were measured in weeks. That constraint is gone. Anyone can ship a variant in hours. The new constraint is knowing what to make. Volume is cheap, insight is scarce, and the teams that figure out what the account is telling them about their next creative outperform the teams that simply ship more.We cover Canva Grow’s architecture in detail. The platform ingests creative, the product being sold, prior design history, brand guidelines, and live ad performance from every platform the company runs on. It puts that context in front of the teams making the ads, written in plain language. The contrast with the incumbent stack is architectural. Most performance stacks live in three different products with three different owners: the ad platform, the analytics platform, and the creative tool. Each has context the other needs. None of them share. Canva Grow’s play is to compress that into one surface where the context is always present and always current.We go into the AI layer. George is direct on this. AI is a multiplier for creative teams that already have feedback loops running, and a noise amplifier for teams that do not. The failure mode is always the same: generate ten times more variants without adding a corresponding ten times to your learning capacity, and the signal degrades. The ads that work get buried. The ads that do not work get re-created in the next batch. Agentic layers only help when the loop underneath them is already closed. Without the loop, the agent is shipping faster against the wrong assumptions.We cover why…
