Share with your CMO
Andy Parton is betting that the real gap in AI marketing isn’t access to tools, it’s judgment about which decisions AI should touch and which it shouldn’t. After seven years in senior roles at Diageo and BAT, where he led campaigns across Guinness, Johnnie Walker, and Vuse across more than sixty global markets, Parton has launched Destreza, an AI-native marketing consultancy in London. The firm runs a proprietary network of specialist AI agents, with Parton as the single accountable human on diagnosis, strategic choices, and final recommendations.
What this means for your business
The CMO most exposed here isn’t the one ignoring AI, it’s the one who’s already deployed it broadly and is now drowning in output with no framework for deciding what the output is actually worth. If your team produces more research, more content, and more creative options than twelve months ago but brand performance hasn’t moved, Parton’s premise names your problem accurately. The question isn’t whether you have AI in the stack. It’s whether any human in the organization is accountable for the strategic choices AI is quietly making for you.
Destreza’s operating model (a layer of specialized AI agents supervised by one senior practitioner who owns the final call) is a direct challenge to the way most enterprise marketing functions are structured right now. Most large consumer brands have distributed AI adoption across agencies, internal teams, and platform vendors, with no single point of accountability for where the technology is actually shaping brand decisions. Parton’s model concentrates that accountability deliberately. Whether a one-person consultancy can hold that position against the scale of a WPP or Accenture is a fair question, but the structural argument, that diffuse AI adoption without human accountability degrades brand quality rather than improving it, is hard to dismiss.
The sharper signal here is what Parton’s exit from BAT implies about where enterprise AI talent is heading. Senior practitioners who’ve spent years running AI deployments at scale inside large consumer businesses are concluding that the consultancy model gives them more leverage over outcomes than the corporate one does. If that pattern holds, CMOs inside large organizations will find themselves competing for AI marketing expertise with boutique firms that can move faster and charge more selectively, while their own AI capability gets shallower. The renewal to weigh differently isn’t the agency contract. It’s whether your internal AI marketing lead has enough room to actually own decisions, or whether they’re already shopping for the exit.
