Watertight Marketing

Watertight Marketing is a multi-award winning business growth methodology created by Bryony Thomas. Used by thousands of businesses to double and triple their profits, Watertight Marketing stops you leaking profit, supporting you to out-think rather than out-spend your competition.

If you are new to Watertight Marketing, reading the second edition of Watertight Marketing is a great place to start. You can download your free sample of this multi-award-winning book here.

As a Watertight Marketing Certified Practitioner, I am trained and approved in using the Watertight MarketingTM methodology. One of the very first people to do the Watertight Marketing masterplan which I applied to my own business, I was so impressed that I undertook the rigorous training and assessment process so that I could become certified to use the methodology and tools with Nellie PR clients.

“I first ‘met’ Ellen on Twitter in 2009. We connected over a mutual passion for marketing that delivers sales results, and having both previously worked at Experian. Having worked with Ellen on my own press profile, on PR projects for clients, and each having attended one another’s courses, I was delighted when she wanted to join the Watertight Marketing Certified Practitioner community. Although her depth specialism is on PR, Ellen’s knack for big picture strategy has always impressed me. She joins the dots on how marketing techniques combine to deliver real commercial results. Thoroughly recommended.”

Bryony Thomas, author and founder of Watertight Marketing


I work with businesses and organisations to audit and understand where they are leaking profit, prioritise their marketing and put a plan in place for marketing transformation. I work with you to Tweak your Leaks and Turn on the Taps.

Watertight Marketing works best for scale-up seven-figure businesses. I work directly with CEOs, MDs, business leaders and those responsible for sales and marketing.

Watertight Marketing is for you, if:

  • You are looking to build a marketing function and move away from marketing overwhelm and exhaustion
  • You are stepping things up, want to make more confident marketing decisions and achieve sustainable sales growth
  • You want to stop wasting money on marketing and attract more of the customers and clients you love
  • You want clarity to focus your marketing efforts and start getting a return
  • You want to understand your customers’ buying journey.


You can access Watertight Marketing support and expertise from me in the following ways:

  • Touchpoint Leak™ Traffic Light Report: an online tool with accompanying videos and follow-up support from me to help you find out where to focus your marketing efforts.
  • Touchpoint Leak™ Assessment. This marketing assessment is hugely impactful at helping you to really understand your customers’ buying journey to identify where you might be leaking profit through poor or no marketing activity
