Most people assume influencer math is simple. Get more followers. Land bigger sponsorships. Make more money.
Julie Lancia and Jodie Kammerer – The Design Twins – have 2.8 million followers. Brands pay them $5,000 – $10,000 for a single Instagram post. That’s the visible part.
What you can’t see from their feed is that sponsored content generates $200,000 to $400,000 per year. Real money, but again, not where most of their income comes from.
The bulk of it ($300,000 to $500,000) comes from something most mega-influencers treat as side income – Amazon affiliate commissions.
The result is income that shows up whether they post everyday or not. Money from content they created six months ago. Revenue that compounds instead of resetting every month.
Here’s what they built, and what you can actually use.
How free pillows became a $300K commission business
Jodie Kammerer wasn’t trying to build a business. She was trying to make her house feel less chaotic.
While working in her family’s senior care business and raising two boys in the Bay Area, she was renovating a fixer-upper on whatever budget was left after the mortgage cleared.
DIY projects on weekends, figuring out how to make small spaces work. It was the creative outlet she needed to keep her sane.
In 2014, she started posting those projects on Instagram. Her twin sister Julie was doing the same thing.
People kept asking where they bought stuff, how they made it work cheap, what actually held up with kids.
By 2016, they made it official: The Design Twins.
The audience grew fast. Brands noticed. They started shipping products to the twins’ houses.
Pillows showed up. Decorative wreaths. Seasonal signs. It felt like validation until the credit card bill came.
That’s when the realization hit – they were decorating their homes, but “free pillows” didn’t pay for the groceries. They needed actual money.
Most influencers at that point would chase bigger sponsorships, more followers, higher rates, or better brand deals.
But Jodie noticed something simpler: her followers were already buying this stuff on Amazon. They’d ask about a product in the comments, she’d answer, and then they’d go find it themselves.
What if she just got paid when they bought?
Amazon’s affiliate program wasn’t sexy. Three to four percent commission on someone else’s products.
But it meant she could curate instead of negotiate. She could recommend a hundred products instead of waiting for five brands to approve contracts. And most importantly, it would earn whether she posted that day or not.
Within eighteen months, Amazon commissions were generating more than sponsored content.
381 items earning while they sleep
The twins started with fifty products in their Amazon storefront. Then a hundred. Then they realized something: every item they added kept earning commissions long after they posted it.
As of today, their storefront’s contain 381 curated items organized exactly how their audience thinks. Not by brand or price point, but by the actual problem someone’s trying to solve on a Saturday afternoon – kitchen essentials, bedroom refresh, seasonal décor.
Each of those items generates ten to fifty dollars monthly from organic Amazon traffic alone—people finding their storefront through search without any promotion.
That’s $3,800 to $19,000 in monthly baseline income.
But the real money comes when they actively promote items through their content.
When a follower uses their link to buy a throw pillow, Amazon’s algorithm takes over and shows that shopper matching curtains, a rug, lamps. The twins earn commissions on everything purchased in the next thirty to ninety days. They get paid for what they recommended and everything Amazon suggested afterward.
Then there’s the income stream most influencers don’t even know exists.
Amazon features the twins’ product review videos directly on product pages.
Strangers shopping for storage bins watch their video, make a purchase, and the twins earn a commission at about half their normal rate.
That generates an estimated $50,000 to $100,000 annually from people who never followed them, never saw their Instagram, just watched a video Amazon served up.
Distribution multiplies all of this.
One Instagram carousel about kitchen organization becomes a TikTok short, a blog post ranking in Google, a Pinterest pin capturing search traffic for months, a Facebook post, a YouTube Short.
Twenty to thirty pieces of content monthly across six platforms creating constant traffic back to those 381 items.
Content takes time to create, but each piece keeps generating commissions long after it’s posted. A blog post from six months ago still ranks in Google and sends traffic to the storefront. A Pinterest pin from last year still drives sales.
Brand deals work differently. Every single one requires negotiation, contract review, content approval, and revision rounds. You get paid once, then start over. The affiliate storefront keeps earning from work you did months ago.
The math isn’t even close. But there’s a reason their conversion rates run higher than solo creators running the same playbook.
Why being twins doubles sales
When identical twins tell you to buy the same throw pillow, something shifts in your brain.
It doesn’t register as a sponsored post. It feels like two friends independently came to the same conclusion.
That psychological validation converts at rates two to three times higher than when a solo influencer makes the same recommendation – it’s effectively a built-in second opinion.
What their audience doesn’t see is how professionally they’ve divided the work.
Jodie handles the creative experiments and takes the risks with content. Julie manages business negotiations and polishes the presentation.
It looks spontaneous. Behind the scenes, it’s specialized roles producing forty to sixty hours of content weekly while appearing to work part-time.
The positioning matters just as much as the twin dynamic.
They explicitly target Middle America. Faith-based households. Suburban moms working with tight budgets.
Coastal influencers largely ignore this demographic, but it represents massive home decor spending.
The twins positioned themselves as guides who share the same constraints, not aspirational celebrities shopping at boutiques their followers can’t afford.
When they curate Amazon products, the audience trusts the filter because they believe the twins genuinely understand what it’s like to make a house work on $200 a month.
“We already dug through thousands of Amazon options so you don’t have to waste your Saturday scrolling.” The curation only has value because the twins have proven they share their audience’s taste, values, and budget reality.
What works without the twin advantage
What you can’t replicate: the twin advantage, ten years of audience building, 2.8 million existing followers, or the family business that provided financial runway during early growth.
What you can replicate: the curation model itself.
Pick a marketplace where your audience already shops but faces too many options.
That could be Amazon for physical products, software tools for business owners, online courses for specific skills, or service providers for local needs. The model works anywhere people pay for filtering.
Build your recommendation hub as the foundation, not supplemental income. Organize by how people actually solve problems, not by category or brand.
Your hub needs to feel like a helpful friend’s vetted recommendations, not a random collection of affiliate links.
Start with enough recommendations to be genuinely useful.
For physical products, that’s fifty-plus items organized by use case.
For software tools, maybe twenty vetted options across different functions.
For courses or services, ten to fifteen carefully chosen recommendations.
The goal is comprehensive curation, not random link dumping.
Create once but distribute everywhere.
Adapt each piece of content to platform formats. Instagram for immediate engagement. Pinterest for evergreen search traffic. TikTok for discovery. Blog for Google rankings. The core curation work stays consistent.
Pick explicit positioning and stick to it.
The twins chose budget-friendly home decor for faith-based Middle America. You need equally specific positioning. Match your audience’s values and constraints. The filter only works if they trust you genuinely share their perspective.
Avoid the service trap.
Notice what the twins don’t offer: custom interior design consultations. One-on-one client work. Bespoke services that don’t scale.
They teach and curate instead of delivering custom solutions. That choice keeps the business scalable.
The Design Twins built something that doesn’t look sophisticated. It looks like two sisters sharing Amazon finds. That’s the point. The best systems don’t announce themselves.
They saw that their audience was already shopping on Amazon. They positioned themselves as the filter between infinite options and what actually works for their specific market. Then they earned commission on the value of that curation.
The model works because it solves a real problem: choice overload in a massive marketplace.
If you can credibly solve that problem for a specific audience, the monetization architecture is already there.
Whether it’s physical products, software tools, service providers, or educational resources, the model is the same: become the trusted filter for a specific audience facing too many options.
Create content once, but make it work across multiple discovery channels. A YouTube video becomes a blog post becomes social clips becomes email content.
Different platforms capture different moments when people are ready to solve their problem.
Pick positioning narrow enough that your recommendations carry immediate credibility. Generic advice from “productivity expert” gets ignored. Specific guidance from “productivity tools for solo law firms” gets trusted. Your audience needs to believe you’ve already made the mistakes they’re trying to avoid.
Skip the custom work trap. Consulting and service delivery feel like faster money, but they cap your earning potential at your available hours. The twins don’t get involved with redesigning homes. They curate products and teach systems. Both scale without adding time.
The Design Twins saw their audience already making purchases but struggling to sort through options. They positioned themselves as the pre-filter, earned commissions on the decision-making value they provided, and built distribution that compounds rather than resets.
The model works when you solve the gap between “I need something” and “I know which specific option to buy.”
If you can close that gap credibly for a specific audience, you’re on the way to building a curation business, and the infrastructure is already there.
