FUTURE MARKETING TEAMS WILL LIVE IN GITHUB

Marketing teams will centralize work in GitHub to move faster and reduce chaos from scattered tools. It replaces fragmented systems like docs and analytics platforms by storing all files, history, and updates in one repo. This setup lets teams track every change, access real time business context, and avoid time lost searching for information. Pairing it with AI tools like Claude Code allows instant analysis across files and faster campaign creation. Small teams under 5 people and large teams over 100 people can improve output speed by up to 10x through better organization and shared context.

WHY THE ERA OF THE MADISON AVENUE HOLDING COMPANY IS ON ITS WAY OUT

The advertising holding company model is being dismantled across Madison Avenue, with WPP reorganizing into four operating divisions and competitors pursuing similar consolidation. Publicis Groupe is the furthest along, having spent 10 years integrating its agencies into a single company and delivering 5.9% organic growth in Q4 2025. Analysts note the shift is driven by both Wall Street pressure and preparation for AI, as firms move toward platform and subscription-based revenue rather than traditional time-and-materials billing.

HOW FISHWIFE BUILDS MOMENTUM THROUGH NEWNESS

Fishwife treats social media as an expression of constant brand momentum, maintaining at least one major announcement per month and dedicating roughly 75% of the brand marketing manager's time to planning newness. When the sardine health trend took off online in early 2026, retail unit velocities tripled and DTC sales doubled compared to the previous quarter. The team invests in creators who are already part of the Fishwife community rather than running broad discovery campaigns, and spent almost nothing on influencer marketing until about 18 months ago.

Train Claude on this library along with tone and ICP to create skills like ad copy, headline, creative brief, and cold outbound email generators. Next, gather and enrich company and persona data with Clay and Apollo. Have Claude analyze ICP tiers for both accounts and personas, then feed those insights back into the skills. This setup allows personalized campaigns and outbound sequences for every audience and account type.

NOTHING GOES VIRAL BY ACCIDENT

Virality is often manufactured through tactics like clipping, which helped Braden Peters generate over 1B views in a month from 34,667 videos and 645 clippers. Clipping acts as a paid distribution engine, and it is now standard practice for creators and brands that want scale. Marketing is shifting toward extreme segmentation and personalization, as AI lowers production costs from about $100,000 for ad variants to near zero and enables highly tailored content for micro-audiences. This shift improves ad ROI and relevance, but it also increases content volume and competition for attention. Brands must balance this noise with a clear narrative, since fragmented messaging weakens positioning while consistent storytelling strengthens it across channels.
