Everyone Asks What You Can Sell.Almost Nobody Asks What You Can Defend.
The difference surfaces the day Amazon comes knocking.
Getting approved feels like the finish line, so that's where the teaching stops. Nobody walks you back through the list to show you which of those brands have a real trademark and a real owner behind them, and which are names on a listing with nobody to answer for the product. One of those you can defend. The other one you can't, and you find out which on the worst possible day.
The Modern Builder's Stack is the pipeline that sorts them first.
Built for the Modern Arbitrage Reseller. If you haven't made your first Amazon sale yet, this isn't your starting point.
"One client spent an entire Saturday sourcing and came back with four maybes. Not four buys. Four maybes. The next week he ran the pipeline and came back with a short list he had no questions about. He made it to his kid's soccer game that afternoon."
Brian Olson, Official Olsons

The Map You Were Given Was Drawn
The Map You Were Given Was Drawn
for a Road That Has Been Rerouted.
The teachers you learned from earned their credibility. They built real businesses. But the platform evolved and what they were teaching did not keep pace. You are not alone in feeling stuck. The map just needs updating.
01 / gating
Gated Out Without a Clue
You find a product with solid potential. You click "Sell on Amazon." And you're blocked. You don't know what you're approved for, so everything feels gated.
02 / confidence
Thirty Minutes In. Still Guessing.
You're deep in Keepa tabs, calculator windows, and Google searches. Fifteen to thirty minutes on a single ASIN, and you still cannot say who is behind the brand, or whether the source would hold up if Amazon asked.
03 / data
Charts You Can't Read
Keepa is loaded, every line is turned on, and the chart looks like noise. You know the data matters. You just can't decode it.
04 / compounding
Starting From Zero Every Session
Every Monday is a blank page. No compounding. No infrastructure. Just grinding the same manual process and hoping something sticks.

Bridging the Gap
Last year
Our first course, and everything that shipped with it. we built a system that matched 24,000 ASINs a day
Shipped as Bulk Sourcing, now Sourcing Solved. to sources, and showed how to mine brands
Training 2, inside Ungating Solved. you already had approval for. That was Keepa's daily quota at the time, and we hit the ceiling every 24 hours. Keepa raised it to 36,000 this year and we hit that one too. Finding and matching them wasn't the hard part.
Ungating Solved's next generation became this Modern Builder's Stack.
Then we had to build a second system to protect people from the first one. A list of 36,000 ASINs you can't defend isn't an opportunity. It's inventory you can't back up, and you won't know which rows until Amazon asks.
There's a gap between an ASIN you could theoretically sell and a purchase you'd actually make. Most of this industry hands you the first thing and calls it the second.
Closing that gap takes three moves.
01. Pull the ASIN.
Storefront stalking. Keepa Product Finder. Brand mining. This part is cheap and effectively infinite.
02. Match it to a source.
Matching against the Five-Tier Trusted Sources standard. Now it has a buy cost and a source that will produce documentation when Amazon asks.
03. Evaluate it.
The Pre-Flight Inspection and the 3-Step Check. What survives both is worth your capital.
A Testable Lead is an ASIN you're approved to sell, matched to a source Amazon will accept as an authorized source (if asked), that has passed your Pre-Flight Inspection and cleared the 3-Step Check.
Everything before that is a candidate. Most of this industry counts candidates and calls them leads. That's why your database has 80,000 rows in it and you don't know how many of them are legit brands and can be bought from trusted sources.
The difference is not how many came out. It is what got applied.
Same seller. Same 80,000 rows. The only thing that changed is how many judgments ran against them.
Other systems
80,000 rows.
No judgment applied.
Nothing in Jane's database had been tested against a real brand owner, a source that produces documentation, an inspected listing, or the numbers. Two rows turned out to be safe to act on. The other 79,998 were candidates somebody counted and called leads.
Our approach
Four judgments.
386+ she can defend.
Same seller, run through the standard. Approved brand with a real owner, source classified by the documentation it produces, listing inspected, numbers checked. 386+ came out the far side, and she can say which test each one passed.

// the approach
Not Four Separate Skills. One Unified Pipeline.
Knowing what you can list, and what you could actually answer for if Amazon asked. Finding it at scale from sources that produce documentation. Reading the chart. Making a confident decision in seconds. Most sellers treat these as four separate problems. They're not. They're one pipeline, and the output of each step becomes the input for the next.
The Modern Builder's Stack is that pipeline. Built in order. Deliberately.
You still need the volume. What you have never had is a standard to run it through.

// what's inside
Two Parts. One Pipeline.
Four judgments run across the two parts. The first tells you which brands have a real owner behind them and which sources can produce documentation. The second tells you which listings and which numbers are worth your money. Neither one works alone.
Part 01 / Find It
Brands With a Real Owner.
Sources That Hold Up.
Sources That Hold Up.
Most sellers are fighting gates they don't need to fight, and sourcing one product at a time. Then they hear the stories. An account deactivated over a brand nobody ever checked. So they slow down, second-guess every buy, and end up trusting a list somebody else built. Nobody taught them how to tell a real brand from a made-up one, or a source that holds up from one that doesn't. That is where this starts.
01
Modern Ungating
The four ways Amazon gates you, and what to do about each one. Brand master list of 4,400+ brands. Bulk approval checks. Keepa Product Finder Link Generator.

02
Sourcing Solved
Stop sourcing one product at a time. Bulk matching at scale, both the proof-of-concept method and the approved-ASIN method. You leave with the Five-Tier Trusted Sources list: 800+ retailers sorted by the documentation they actually produce.
6 modules / ~50 min
Part 02 / Judge It
Listings You Can Verify.
Numbers You Can Act On.
Numbers You Can Act On.
Everyone teaches you to read the Buy Box, or uses the Buy Box to "help" you make purchasing decisions. The Buy Box tells you what one seller decided to do this morning. It doesn't tell you whether your capital comes back. This half fixes your configuration first, then teaches you to read the things that actually predict the outcome.
01
Keepa Config
Extension setup, Product Finder, Product Viewer, column presets. Complete configuration from scratch. You leave with our importable column presets and saved Product Finder configurations, so you start from a working setup instead of a blank one.
5 modules / ~50 min
02
Keepa Deep Dive
The 3-Step Check: Velocity, Capital Protection, Profit Potential. Capital protection is the one nobody else teaches, and it's the one that decides whether you get your money back. Live product evaluations on real ASINs. You leave with the Pre-Flight Inspection.
6 modules / ~75 minOnce the pattern is yours, we automate it.
P.A.T.H. Profit Zones runs the 3-Step Check for you: enter your buy cost, get a pass or fail. It's free, and it's yours whether you buy the stack or not. The Pre-Flight Inspection stays manual, because judgment about brand accuracy and listing clarity is the part that shouldn't be automated.
// defensible sourcing
Four Things Nobody Else in This Space Is Teaching You
Which brands are worth your approval. Which sources hold up when Amazon asks. Which listings you should never touch in the first place. And which numbers justify putting your money on it.
A map that shows every road is not a map. It's a picture of the ground. What makes it useful is knowing which roads are safe to travel on.
The Brand Vetting Protocol
Taught in Modern Ungating
Getting ungated for Billy Bob's misbranded bundles is not an asset. It's exposure.
We call those Phantom Brands: no registered trademark, no real owner, nobody to stand behind the product when a claim lands on your account. Anyone can hand you 26,000 approved brands. Check how many of them actually exist.
Our master list is 4,400+ brands, pre-classified single and multi-category, vetted against one question: does selling this give you something you can defend, or nothing at all?
The Five-Tier Trusted Sources Framework
Taught in Sourcing Solved
A match is not a source. A source that can't withstand scrutiny from Amazon is a problem that could cost you your ability to sell on the platform.
800+ retailers classified by the kind of documentation they actually produce. Direct retailers with brand authorization. Familiar suppliers. Traditional sales channels. And the protocol for evaluating a source you've never purchased from, before you spend a dollar with them.
The Pre-Flight Inspection
Taught in Keepa Deep Dive
The ASIN goes in your database. Before you act on it, three checks. Not economics. Integrity.
Brand. Is the brand field correct? Does it match the picture, match the title, spelled right?
Items listed. Can you supply every item in the listing? Count per unit, single versus multi-pack versus bundle.
Listing clarity. Will the buyer expect something different than what you'd ship? Read the customer comments. Are you clear on the offering?
Three questions that stop the wrong ASIN before it turns into a return, a claim, or an account review. You build it inside the Keepa Deep Dive, before you ever open a chart.
The 3-Step Check
Taught in Keepa Deep Dive
A listing can be a real brand, from a source that holds up, and still be the wrong place to put your money. That is a separate question, and it gets asked last.
Velocity. Is it actually selling, at a rate that clears the quantity you would buy?
Capital protection. If the price moves against you, do you get your money back out?
Profit potential. After every fee, is what is left worth the capital and the shelf space?
Capital protection is the one nobody else teaches, and it is the one that decides whether your money comes back. Once the pattern is yours, P.A.T.H. Profit Zones runs the check for you, free, whether or not you buy the stack.
What defensible sourcing actually means.
Nobody can promise you'll never get an IP complaint. A brand can decide tomorrow that it doesn't want third-party sellers on its listings, and it can say so about a product you bought legitimately from an authorized distributor. Anyone telling you their system prevents that is selling you something we wouldn't buy.
What you can control is whether you have an answer that can make it go away. That takes three things, and the stack builds all three.
A real brand with a real owner. Not every brand will respond, but the right brands have real owners, and that at least gives you somebody you may be able to work the problem out with. Complaints can get rescinded once you work them through, whether or not you keep selling that brand afterward. A phantom brand gives you nobody to talk to at all.
A source that produces an invoice Amazon will accept when they ask for it. Not every receipt or invoice qualifies. Several things determine whether yours can hold up when Amazon asks for it, and we cover all of them inside the stack. Some unfortunate resellers don't find out theirs won't work until it's too late.
A listing you inspected before you committed capital to it. The brand field, the item count, the buyer's expectation. Half the complaints in this business aren't attacks. They're self-inflicted, and they trace back to an ASIN nobody looked at closely.
The Pre-Flight Inspection tells you whether you should be listing on that ASIN at all. The 3-Step Check tells you whether to test the waters with it.
// the transformation
Before the Stack vs. After.
Before: Grinding Without a System
- No clear picture of what you're approved to sell
- Handed 26,000 approved brands with no way to tell which can be trusted
- Hours of sifting brands and ASINs by hand just to work out what is legitimate
- Buying inventory before realizing you can't list it
- Manually sourcing one product at a time
- Keepa charts look like noise, every line turned on
- 15 to 30 minutes per product evaluation, still unsure
- Starting from zero every single session
After: A System That Compounds
- Master brand list built, filtered to your approvals
- That list vetted down to real trademarks and real owners, so every approval is one with a real owner behind it
- Every listing checked that what the listing says it is matches what would actually ship
- Candidates surfaced at scale, then cut down to the ones you can defend
- Sourcing to your approvals, never against them
- Clean, properly configured Keepa, readable at a glance
- 60-second buy decisions once the 3-Step Check becomes pattern recognition
- Every ASIN inspected before you act on it
- Each session builds on the last
// real results from real sellers
Real Numbers. Real Wins.
Notice which number is small. That's the one that took work.
Every number below is what survived judgment, not what a search returned. Each one came through the same two pipeline filters: brands vetted against the Brand Vetting Protocol, and sources classified by the Five-Tier Trusted Sources Framework. The Pre-Flight Inspection and the 3-Step Check then run on what is left, one ASIN at a time, before any money moves.
3,966 candidates.
55 leads.
Was sourcing one brand at a time. One pipeline run surfaced 3,966 candidates across 528 approved brands, and the standard cut it to 55 that had a real brand owner and a source behind them.

154 worth his money.
Ran the full pipeline at scale. The standard threw out 99.5% of what it found, because 99.5% could not show a real brand owner and a source that holds up when Amazon asks. That's the point.

80,000 candidates.

// who built this
Seven Years Selling. Five Years Coaching.
Brian and Robin Joy Olson have been selling on Amazon for seven years and coaching arbitrage sellers for over five of them. That combination matters.
The selling keeps them close to the platform as it actually operates today. The coaching keeps them close to where real sellers are getting stuck right now.
The frameworks in the Modern Builder's Stack were built from that experience. From being in the data every day and noticing what was changing, what was getting easier, and what nobody in this space was talking about yet, and still isn't, because they don't understand it.
We host the New Era Reseller podcast, where we work through this material with sellers every week.
"We don't hand you a system and tell you to follow it. We show you exactly what decisions you have to make to build a solid foundation, and then you build it your way."
Brian & Robin Joy Olson, Official Olsons"They offer the 'why' behind the work, address the frustrations, and show you the payoff. That's real in my book."

// right fit?
Made for the Modern Arbitrage Reseller
You are one person, or one person and a VA. You have already sent inventory in to Amazon. Maybe you have boxes in the garage that seemed like a good idea, a spreadsheet you stopped trusting around row four hundred, and a nagging feeling that the sellers posting big numbers know something structural you don't. They do. This is it.
This is for you if:
- You're putting in the work but something isn't clicking the way it should
- You're hitting gated walls without knowing what you're actually approved to sell
- You're sourcing from the same well thousands of other sellers are drawing from
- You have Keepa installed but it's configured wrong, so every chart looks like noise
- You're spending 15 to 30 minutes per product evaluation and still aren't confident
- You've been selling long enough to have a database of leads you don't trust and a sourcing routine you've outgrown
- You can't reliably tell which brands and which sources you're safe to trust
- You can commit 10+ hours a week to consistent sourcing, prepping, shipping, and tracking. This is a system, not a shortcut, and it only compounds if you run it
- You're ready to see how all four pieces connect into one pipeline
This is NOT for you if:
- You're already running bulk sourcing sessions matching 10,000+ ASINs to trusted, verifiable sources
- You already have a working decision framework you trust
- You're not doing online arbitrage, retail arbitrage, or wholesale on Amazon
- You don't plan to use Keepa (about 29 euros/month). It's a non-negotiable tool.
- You haven't made your first Amazon sale yet. This assumes you already know the mechanics of listing and shipping in.
- You don't care about protecting your account health
- You're not looking for a better system, just confirmation it can't be done

Frequently Asked Questions
What order should I go through the courses?
The sequence matters: Modern Ungating first, then Sourcing Solved, then Keepa Config, then Keepa Deep Dive. Each course feeds into the next. That said, if your Keepa is a mess and that's your most urgent pain, you can start with Config. The stack works best in order, but any single course stands on its own.
How long is the training total?
Under four hours across all four courses. All courses are designed to be applied as you watch. You can be fully operational the same day.
Do I need a Keepa subscription?
Yes. Keepa costs approximately 29 euros/month or 290 euros/year. If you're doing arbitrage on Amazon, it's a non-negotiable tool and the training assumes you have it. The Config course walks you through setting up your account from scratch.
Are there other tools I'll need to pay for?
The workflow uses ArbiSource for bulk matching (code OFFICIALOLSONS for 30% off) and GateKeep for bulk approval checks (first-month free code included). Both have costs. You don't need them on day one, but the full pipeline is built around them.
I'm brand new to Amazon. Is this for me?
Probably not yet. The pipeline starts after you already know the mechanics of listing and shipping in. If you haven't made your first sale, go get that first. Come back when the problem is scale, not start.
Can I buy just one course instead?
Yes. All four courses are available separately at $297 each. You get the full course and its assets. What you don't get is community access, which only comes with the stack. That's the piece most people tell us they'd miss.
What makes a lead "testable"?
An ASIN you're approved to sell, matched to a source that Amazon will accept as an authorized source (if asked), that has passed the Pre-Flight Inspection and cleared the 3-Step Check. A lot of tools will hand you thousands of sellable ASINs and call them leads. A sellable ASIN with no source is a row in a spreadsheet. We count what you can act on.
// the honest version
Volume Is Not the Constraint
You saw what my first system does. Bulk matching is automated too, which is how a session hits 10,000 matched ASINs in the time it takes your coffee to go cold. Neither of those is the constraint it used to be.
For the last couple of years this market appeared starved of opportunity, because people didn't know how to read the new map. That's what drove resellers away. They were handcuffed by gates they couldn't see, brand lists they couldn't trust, and sources they knew were getting other accounts suspended. The ones who stuck around were desperate for anyone to hand them a batch of ASINs they were approved for. That's understandable. Our clients were in the same spot.
More roads on the map was never the problem. Nobody marking which ones are washed out and treacherous to travel: that's the problem.
But desperate and defensible are different things. And without judgment, you don't scale a business. You scale chaos.
That's what's happening right now across this whole space. Bigger lists. Faster matching. More rows. And no standard for what any of it means. We expect the deactivations to keep coming, because the tools got faster and nobody got more careful.
Volume is now easy. Knowing what counts is the whole game.
// your move
Two Choices.
Option 1: Keep Folding the Same Map
Keep hitting gates you don't understand. Keep sourcing from the same wells everybody else is drawing from, with no idea which of them Amazon will actually stand behind. Keep staring at Keepa charts that look like noise. Keep spending 15 to 30 minutes per product and still not being confident. Keep counting rows you don't trust. Keep starting from zero every Monday.
Option 2: Turn On the GPS
Learn the complete pipeline built for the platform as it exists right now. Know what you're approved to sell and why those brands and not the other ~20,000. Match at scale against sources that hold up when Amazon asks. Configure Keepa so the chart tells you something. Inspect before you evaluate. Then make the call in 60 seconds. Every session builds on the last. The system compounds.
Not ready? Start with P.A.T.H. Profit Zones. It's free, it's the 3-Step Check in a Chrome extension, and it will show you what this way of thinking feels like.
Get Profit Zones Free"This is not a beginner course, and it is not a shortcut. Anyone promising you a magic two-step process is selling something we wouldn't buy. There is no such thing as something for nothing. This is for the Modern Arbitrage Reseller who is not afraid of the work and is ready for a system that finally matches the platform as it exists right now."
Brian & Robin Joy Olson, Official OlsonsP.S. Think about your last sourcing session. How many products did you evaluate? How many did you buy with real confidence? The Modern Builder's Stack is under four hours of training that changes every sourcing session you'll have from here forward. That's the trade.
P.P.S. Somebody will always sell you more ASINs. Nobody is telling you which ones you can defend. That's the gap. That's what this closes.
