Davis says the Invivo Wines project illustrates just how much the advertising world has changed in the past decade. Developing a small, nimble practice has given him the freedom to explore turning some conventional ways of doing things on their head.
"Ten years ago, making that TV ad would have been the first step and then all the other stuff would have been bolted on. Now we do it the other way around."
He says his ambitions when he first set up The Goat Farm were simple: to work with people he liked and enjoyed the company of - and to find interesting and effective ways to solve others' business problems.
"We tend not to have more than three or four clients at a time, which is nice, so everyone gets decent personal attention. They range from large corporates, who I guess are looking for a different approach to their marketing and customer connection, to small start-ups and everything in between."
Instead of employees, the company draws on the services of a "loose whanau" of around 10 senior industry practitioners who contract to the firm, explains Davis.
"They come together to do cool stuff as projects dictate," he says.
"A typical Goat Farm project involves three or four people, and takes around three or four months.
"It's like a farm, it's not a factory where everyone comes in at 8am when the whistle blows.
"Some days we'll just watch the grass grow and other days we'll work around the clock."
But the reality is there's more of the latter than the former; Davis says his biggest issue is not taking advantage of the business owners' "absolute freedom to work every hour of every day".
"The main challenge is to find time in the day every day to give every client the attention and the quality they deserve. Because that's what they're buying into, they're buying into a relationship, not a commodity. I think the biggest fear clients have is that, as your business grows, they'll lose touch with the principals."
However, Davis says the scale and power of the personal networks being created by people through social media are a big help. Bonds that used to be formed with colleagues and clients over long advertising lunches can now be forged and maintained online, he says.
Davis is clearly not a fan of the long lunch. A former air force pilot, he says he'd prefer to fly clients in his plane to Great Barrier for a coffee (among the many other hats he wears, Davis also runs an aeroplane rental business).
Getting up in the air is also a great way to focus and clear the mind when you're a business owner, he says.
Almost five years down the track, Davis says the original ambitions he had in the firm - to work with people he liked and solve others' business problems - haven't changed and achieving those aims is how he ultimately measures his success.
"For an ex-military guy this is going to sound really soft but, for me, success is really going to sleep happy every night," he says. "That comes from working all day with people I like and doing work that does the business for them."
