We bring big-brand thinking with a personal touch. Founded by two marketers both with 20+ years of experience across industries, from events and telcos to gaming and tech. Plug-In was born from a shared belief: that great strategy and smart execution should deliver real, measurable growth.
Our founders met at the very start of their careers, studying to become Chartered Marketers. After years of leading marketing, commercial and digital teams & projects across global brands, they reunited to create Plug-In, a marketing and consulting agency that puts clarity, creativity, and commercial impact at the heart of everything.

Worked with Jen at Ascential where we drove the Money20/20 FinTech brand together. Hard to find a more results driven marketer who is also one of the best strategy drivers and implementers I have worked with. Also a joy to work with whilst ensuring that she takes all on the journey with her.

The safest pair of hands in the industry. She's smart, resilient and has one the highest EQs I have seen in a leader. A self starter who likes to get her hands dirty - she really helped me steer the M20/20 ship at Ascential. I owe her any restful sleep I got during that time.
Melissa has a remarkable ability to make everyone feel truly heard, while also bringing an infectious energy to every interaction.

I had the privilege of working with Jen during my time as COO at Paris Blockchain Week, where she served as CMO. Jen is an exceptional strategic marketer and an accomplished business leader, with a rare ability to balance long-term vision with immediate execution.
She brings a deep understanding of how marketing connects to the broader business strategy, especially in the context of large-scale events. Jen is not only highly effective in delivering results, often under tight deadlines, but also inspiring as a leader. Her team respects and admires her, and it’s easy to see why: she leads with clarity, empathy, and purpose.
One standout example of her impact was when she led the marketing for a brand-new event on a highly compressed timeline. Her leadership and strategic direction played a critical role in its success.
Jen asks the right questions, challenges assumptions when necessary, and ensures that everyone around her understands the "why" behind the work. She also brings a warm, engaging presence to every interaction and remains composed under pressure.
