Growth Made Great

Our Five Mark Growth Method

Here’s how we see it. People are the why. Growth science is the how, and your results the proof. Now, here’s the way.

Eight years in the making and special to us, the Five Mark Method is a flexible, modular framework that applies Growth Science to your startup. The result is a wire-tight, structured way of turning truths and ambitions into never-look-backs. Simple

Siân is an extremely competent and professional digital marketing strategist. She really understands the dynamics of working with high-growth startups. Siân was very helpful in defining successful marketing channels for our startups, understanding key metrics and achieving traction channels at the early stage of the company.

Kirsten Connell, Octopus Ventures

We started working with Siân and The Fifth Mark at the beginning of the first lockdown when we had a barely functioning website. We needed to work quickly to shift all of our attention to growing our eCommerce. Siân helped bring clarity to the mind-boggling world of digital marketing and developed a concise growth strategy. Working with Siân and The Fifth Mark Team resulted in huge growth for our business across the board, not just DTC. The Fifth Mark’s expertise and professionalism has been massively refreshing and has built a foundation for us that I will be forever grateful for. No doubt that we will continue to work together.

Theo Garcia, Co-Founder & CMO, Solo Coffee

Working with Siân and The Fifth Mark team has and continues to be a pleasure. They have helped steer us through a huge growth period, always acting with honesty, determination and intelligence, and have driven our Google and social advertising from strength to strength. They treat our business like it’s their own and have built us a strong foundation for long term, sustainable growth. Highly recommend to anyone looking to scale fast and efficiently from the start.

Julian Parmiter, Co-Founder, Create Academy

The Fifth Mark were excellent to work with from start to finish. Siân is clearly extremely well qualified to provide digital marketing solutions to a range of businesses, and by working with freelancers who specialise in your industry, you feel like every box is ticked. After our strategy sessions we feel in a much stronger position to grow our businees in the digital space.

James Wales, Co-Founder, Nemo Travel

Siân is not only highly strategic but has a deep operational understanding across the breadth of digital platforms and mediums. This means she ideally placed to inspire and lead teams to deliver at speed but also has the in depth knowledge to challenge, ask difficult questions and ensure the best possible job is done. Siân is an outstanding leader and digital thought leader.
