Google and TikTok just pushed AI creative generation and campaign setup into every advertiser's toolbar. The execution work your fees are partly built on is going self-serve.

What moved

Google launched "Ask Advisor" and an upgraded Asset Studio at Google Marketing Live 2026, a Gemini agent that builds and optimises campaigns across Ads, Analytics and Merchant Center, plus natural-language generation of images, video, copy variants and 1-click creative testing. Source

TikTok unveiled Symphony Agent at Cannes Lions 2026, bringing agentic AI to ad creation, creator discovery and content scaling directly inside the platform. Source

Category context: self-serve "agency in a box" tools (Google Pomelli, Canva Grow, WPP Open Pro) are already eating agency budgets lower down the market. Gartner's 2025 CMO survey found 22% of CMOs say generative AI has cut their reliance on agencies, and 39% plan to cut agency spend. Source

Why it matters to me

None of this touches senior strategic judgement yet, but it is aimed squarely at the production and campaign-setup layer, the part of your fee that's easiest for a client to question once AI makes it fast and cheap. As these tools get slicker, the case for paying an agency to do execution, rather than just strategy and relationship, gets harder to defend.

The entrant angle

There's no single AI-native agency-in-a-box challenger for mid-market UK brands yet. The real pressure is platform-native tools (Google, TikTok, Canva, WPP) stacking up into something a resourceful in-house marketer can approximate themselves, at exactly the £10k to £100k a month budget you compete for.

One move to consider

This week, split one client scope into a visible "strategy + AI-assisted execution" line item. Keep senior strategist time on brand judgement and campaign direction, and let tools like Asset Studio or Symphony handle asset variants, so the client sees the senior relationship as the thing they're paying for, not the production work that's now commoditising.
