3x Growth in 3 Years: Leveraging Prime Day & Other Tentpoles for Compounding Growth

Some brands start thinking about Prime Day in April. The standout brands started building in January... of last year. 

That's not a knock on preparation timelines. It's a recognition that Prime Day rewards compounding investment. The brands that see the biggest lifts aren't the ones who throw the most at the event; they're the ones who've been building share of voice, subscriber bases, and new customer pipelines long before the deal badges go live. Prime Day amplifies what's already working. It doesn't rescue what isn't. 

The Prime Day Opportunity and Its Limits 

During Prime Day 2025, the share of new-to-brand conversions from Sponsored Brands ads rose to 70% on day three of the event — a meaningful window for acquisition. But capturing those customers is only half the equation. What happens after the event determines whether Prime Day was a revenue spike or a genuine growth inflection. 

That's the question GO was asking when we previously onboarded a sports nutrition brand. They were in a competitive category with a roughly 7% advertising investment rate. The data told us there was a real opportunity to steal share, grow new-to-brand, and build loyalty, but it wasn't going to come from event spending alone. It required a strategic reset and a commitment to building something that would compound over time. 

What We Saw, and What We Did About It 

Before adjusting anything, we analyzed competitor behavior and customer data from both Amazon and the brand directly. A few things became clear: the brand had a genuine product differentiator that consumers were responding to, but the messaging wasn't consistently reaching the right audiences. And the advertising strategy, while functional, wasn't structured around the outcomes that drive long-term value — new customer acquisition and loyalty. 

We built the strategy around three decisions. 

Differentiated DSP Prospecting with Sharper Messaging 

The brand's key differentiator was resonating when the right people saw it. We altered campaign messaging to speak to each distinct consumer group rather than running a single broad approach. The goal wasn't more reach; it was more relevant reach. Paid share of voice grew +76% year-over-year, and new-to-brand customers increased +50%. 

ASIN Prioritization Built Around Proven Performance 

We modified which products were featured across search and DSP based on what Amazon data showed was actually moving the needle for each strategy. The products that steal share look different from the products that drive loyalty. We treated them that way. Subscribe & Save growth, which had been minimal, grew +965% as we leaned into the right ASINs for the right audiences. 

Treating Tentpoles as Customer Acquisition Investments 

Prime Day, and every tentpole that followed, wasn't approached as a revenue target in isolation. We understood that customers acquired during peak events have a higher propensity to repeat. Our internal data across consumable brands shows Prime Day customers generate 2x the revenue in repeat purchases over time. That framing changed how we invested: events became acquisition moments, and the always-on strategy between events became the retention engine. 

The Results 

From Q1 Year 1 to Q1 Year 4, the brand grew 3x. 

That number is the headline, but the metrics underneath it tell the fuller story: 

• +76% paid share of voice YoY 

• +50% new-to-brand customers 

• +965% Subscribe & Save growth 

• +35% initial 90-day customer value ($58 → $82) 

• +58% more transactions per purchaser 

• -17% time to repeat purchase 

The Subscribe & Save growth is worth pausing on. Research has found that Subscribe & Save customers demonstrate significantly higher lifetime value compared to regular buyers, with reorder rates doubling after program activation. For a consumables brand, that's not a nice-to-have metric — it's the foundation of more predictable, compounding revenue. Getting there required getting the right customers into the program in the first place, which is exactly what the ASIN prioritization work made possible. 

What This Means for Prime Day 2026 

We're not suggesting every brand will see these specific numbers. Every category, competitor set, and product mix is different, and strategy has to be built around what the data actually shows. What we can say with confidence is that the brands we see maximize Prime Day aren't the ones who treat it as their biggest moment. They're the ones who see it as the momentum builder—the stair-step to the next level of performance. 

If your brand is heading into Prime Day without a clear picture of your NTB pipeline, your SNS subscriber base, or how your DSP prospecting pools are built, now is the time to take stock. The event rewards preparation that started months ago, but there's still time to close the gap before it arrives. 

Prime Day is coming. Let's make sure your brand is built to maximize it and what comes after.
