LONDON, UK — trendJack, an AI media intelligence platform for marketing teams, today announced it is now onboarding founding users. The platform gives lean marketing and communications teams signal-to-publish intelligence at the level of a full agency, delivered through an agentic AI teammate called Jack, without the agency retainer or headcount.

Jack works as always-on competitor tracking and trend monitoring software. Jack scans news, social platforms, industry publications and competitor activity around the clock, scores each signal against a brand's own pillars and voice, and delivers newsroom-style trend alerts on only the developments worth acting on. From there, Jack handles on-brand AI content generation, drafting publish-ready posts and comms in the brand's tone, routing them through an approval workflow, and getting them out the door while the moment is still live. It's what the team calls going signal to publish.

"I built trendJack because I was drowning in exactly the problem it solves," said Tamsin Richendoller-Hill, co-founder of trendJack. "I needed something that watched the market for me and handed back the one thing worth acting on, not a pile of raw data I still had to make sense of."

trendJack is built as a social listening alternative and competitor monitoring tool for lean teams. It is also MCP-ready, meaning Jack lives inside the AI assistants marketing teams already use, including Claude, ChatGPT, Cursor and Copilot, alongside Slack, email, Google Drive and Microsoft 365. There is no new dashboard to learn.

The platform is aimed at in-house marcomms leads, one-person marketing departments, and B2B scale-ups that need real-time trend alerts for brands and competitor content monitoring without a big team. Beyond marketing, trendJack is also being positioned for sales use cases, helping teams track prospect and competitor activity as part of outbound efforts.
