Gareth's knowledge of the ever-changing landscape of GA4 is really impressive and he went above and beyond to make sure our team, including senior stakeholders, understood the importance of taking a proactive approach to the migration.”

"What their team has build for us is so incredible. It's unlocked success for the next few years. Even if none of the ads worked [they did] all of it would have been worth it, just for the analytics"

Halter was named New Zealand's fastest growing company with 1539% growth.

“Working with Double was an absolute pleasure from start to finish! The team now feel like family and a real extension of our business. The work they did literally doubled our expectations - they really live up to their name!. They are an incredibly knowledgeable and talented team. I couldn't recommend them enough.”

“Whip-smart, hot-on-the-tools and genuinely curious about how to make things tick better, Reuben, Gareth and the team at Double are the special sauce every business needs to level up its digital marketing ”

“Their super talented team helped us realise our digital potential and reach our goals quicker than we ever thought possible, the sky really is the limit with these guys! They’re super knowledgeable, out of the box thinkers, and an absolute pleasure to work with.”

"I honestly think that hiring Double is one of the best decisions we've made. I truly mean it when I say you're one of the smartest, most emotionally intelligent people that I've met. The results already start to prove that"

“Double has been instrumental in unlocking our growth potential across NZ, AU, and the USA. They feel like a true partner—strongly aligned with our vision, proactive in navigating the ever-evolving digital landscape, and always looking for ways to create impact beyond the immediate scope of their role. They bring a rare combination of strategic thinking, integrity, and a genuine commitment to our success, knowing that shared wins lead to long-term growth for everyone”

“I love it. It’s great, it’s huge for us, it’s beautiful. I love the feel. The AI images just feel so cosy – the effort and money it saved us to actually orchestrate full shoot days, that can now be replaced by great AI. It looks very natural. Not over refined, very approachable, exactly what we wanted. It’s absolutely fantastic.”

“The difference with Double is that they spent time understanding our business, and as a result, we have a solution that works for our business goals. They set up a solution that tracks leads right across every touchpoint – from advertisers, to our website, and then through our network of systems (when everyone else said it couldn’t be done). This means we’re now optimising for leads that convert, not just leads. As a result, this channel has grown from 2% – 20% of our new business with the same spend. To top it off, Double has built a reporting dashboard to communicate this to the business so it can be understood by people outside of the industry, instead of hiding results in digital jargon. I’d recommend Double to anyone looking for a solutions-driven partner who uses data to make sure the job isn’t just done, but done right.”

“Double have been exceptional. Their video ads have made a fundamental difference to our marketing growth. With a data-led approach to perfecting creative, they were able to build better performing ads so that we could scale our ad spend. We now have beautiful ads that our whole team is proud of, and better yet, they really convert! If you really want to grow, I can't recommend Double enough.”

“If you want to deal with a performance agency then these guys should be it. They focus on the results you want to deliver and can help you set up everything to get that result. The whole team is great. The people who are on the tools, coming up with strategy are also meeting with you regularly. This means less changes, faster decisions and execution – more revenue quicker. They will prioritise quick wins to generate revenue quickly before building out smart automated campaigns that keep delivering more. With ongoing tests of our campaigns, landing pages, ads, channels, we were confident that value wasn’t being left on the table, ultimately growing our inbound leads by 500% across NZ, AU and US.”

“Double became part of our business, walking us through every stage of the process and ultimately overdelivered on targets by almost 100%.”


“Double have been nothing but instrumental in the development and success of this company. They’re not your typical digital agency, they think about things differently and get the results you want. Our ROI since engaging them was huge, we’ve booked millions in new work. If you have a chance to work with them, take it. They understand how scale works and the young team has the finesse and adaptability to fast track you to where you want to be.”
Borian Millic,CEO

Double has looked after our brand's marketing for some time. In that time we have seen exponential sales growth in our digital channels and strong growth across over-all, in both our B2B and B2C businesses."

"The dashboard is tremendous. Truly. We just looked at the [product] view-to-purchase rate and will build out an entire range from it. Which connects the dots to the fact that the [product] content performs the best. The presentation of the data is remarkable."
