PRODUCT MARKETING · LONDON · OPEN TO SENIOR PMM ROLES
Jonathan Burns.

Senior product marketing manager specialising in B2B SaaS for technical markets: carbon, cybersecurity and telco. I’ve built the PMM function from scratch three times and run launches at scale.
The short version.
I’ve built product marketing from scratch at Toku, Zivver and Sylvera, and each time it ended up as part of how the go-to-market team ran, with sales, product and demand gen all working from it.
The bits I gravitate towards: ICP work, win/loss and competitive intelligence.
Selected, not exhaustive.
Four pieces of work, and what they changed.
- SYLVERA · 2025–26A launch framework nine flagship launches ran through
- SYLVERA · 2025One positioning, three very different buyers
- ZIVVER · 2023–25Repositioning that opened two new markets
- TOKU · 2022–23APAC market entry, from ICP to demo requests
Three people I’ve worked with.
Jonathan sits in that crucial spot between the product team and the commercial side. He takes messy, complicated product info and turns it into a commercial plan, everything from comms and assets to sales training and internal docs. He’s extremely proactive. He just spots stuff that needs fixing and builds it. A good example: he put together an automated ROI calculator that the sales team now uses all the time.
When you’re looking for someone who “gets it”, Jon is it. He is a rare find of someone who can represent the voice of the customer, understanding and advocating for a point of view that serves their needs and differentiates your company’s offerings.
Thanks to Jon’s research on our buyer personas, I quickly caught up to speed on our 2022 initiatives and objectives.
Occasional, and mostly about doing the job properly.
