We are a repeat customer and we've had great experiences with them. The first was to convert our Gmail account to a business account and the second was to help us with an update on our website. We also like how responsive they were when we've worked with them. I highly recommend them and will keep using them for future needs!

Tom and Bruce at Nautilus were a fantastic help to our team as we navigated the first stages of setting up out podcast. They kept us up to date and were very generous with their time, providing many opportunities to comment on the design of our cover art and logo to ensure we achieved our vision.

I couldn’t be happier with my experience with Nautilus Marketing, especially working with Tom. I needed some support with my website and he was incredible from the very beginning. He took the time to properly understand what I was trying to achieve, then worked tirelessly to get everything in place and make sure I was confident about what needed to be done.

What really impressed me was how much Tom supported me in understanding things from a marketing perspective not just fixing the website, but helping me see how all the pieces fit together to get results. He explained everything so clearly and made sure that, when the project was handed back to me, I felt in control and knew exactly what to do next.

The communication was excellent throughout I always felt listened to and supported, and nothing was ever too much trouble. What really stood out was Tom’s energy and enthusiasm for my success; it’s infectious and made the whole process enjoyable as well as productive.

I was super pleased with the result and the improvements to my site have already made a big difference. This is a company that genuinely cares about getting the best outcome for you. I’ll definitely be using them again and recommending them to others without hesitation. An all-round fantastic business!

Working with Nautilus Marketing has been an incredible experience from start to finish.

From the very beginning, Tom, Jake, and Bruce made me feel fully supported. Not just as a client, but as someone whose vision truly mattered. Their communication is always clear, timely, and human, and the attention to detail at every step is second to none.

Bruce in particular has been outstanding in managing the day-to-day process: super organized, responsive, and genuinely invested in bringing the best version of the project to life.

One of the biggest advantages of working with Nautilus is that they’re a full-service agency. That means you're covered from the very start: brand identity, logo, website, SEO and all the way to scaling with ads, link building, and beyond. It’s rare to find an agency that can stay with you through all these phases and keep the same high level of care and consistency.

If you're looking for a team that listens, executes flawlessly, and actually cares about making you happy! I couldn’t recommend Nautilus more.

I had a fantastic experience with Nautilus Marketing. Bruce and the team did a fantastic job.

No request was to big either, and Bruce and the team were excellent at keeping me updated throughout the entire process.

Towards the end of the project we experienced some minor technical challenges. However, the way Bruce kept me updated during this situation and how quickly the team were able to resolve made the experience reassuring.

I would definitely recommend Nautilus.
