Choosing the wrong product on Amazon can mean months of work and thousands of dollars tied up in inventory.
That is the problem Daniel Miranda FBA set out to address with Sistema Sigma, a methodology designed to research, validate, and launch products in Amazon USA.
The core idea is simple: before committing a significant amount of capital, a product should provide enough evidence that the opportunity is worth pursuing.
What Is Sistema Sigma?
Sistema Sigma is a product selection, validation, and launch system used by Dmiranda Amazon Consulting.
It was developed by Mexican entrepreneur Daniel Miranda, who has worked in e-commerce since 2011 and has focused much of his experience on the U.S. Amazon marketplace.
The methodology emerged after several failed Private Label launches. Based on those experiences, Miranda began building a process around objective validation and rejection criteria.
The system evaluates factors such as demand, competition, cost structure, margins, return on inventory, manufacturing, logistics, compliance, and real market demand before significant capital is committed.
A Method Inspired by the Scientific Process
One of Sigma’s principles is that a product should not be considered viable simply because other sellers are generating sales in the same category.
The methodology looks for additional evidence before launch.
Miranda describes the approach as a method inspired by the scientific process: form a hypothesis, define criteria in advance, and then test the opportunity before deciding whether it should move forward or be discarded.
If a product fails the tests, it is rejected before larger investments are made.
What Does the 80% Success Rate Mean?
According to internal records from Dmiranda Amazon Consulting, approximately 80% of the products ultimately launched by students using Sistema Sigma meet the methodology’s predefined success criteria.
That does not simply mean generating a few sales.
To be considered successful, a product must:
- generate pre-sales during the validation stage;
- project at least a 100% return on the capital invested in inventory;
- continue selling after launch;
- and reasonably meet the revenue expectations established in advance.
The figure comes from internal company records and has not been independently audited. Many products are also rejected before reaching launch, and that filtering process is part of the methodology.
Profitability Before Revenue
One of the principles behind Daniel Miranda Amazon is that high revenue does not necessarily mean a strong business.
Amazon sellers must account for manufacturing costs, logistics, platform fees, advertising, returns, and other operating expenses.
For that reason, Sigma places significant emphasis on return on invested capital.
The methodology generally looks for products capable of projecting at least a 100% return on inventory per cycle, as well as opportunities with the potential to generate approximately $5,000 to $10,000 in monthly profit.
These figures are selection targets, not guarantees.
The Círculo Sigma
The program also includes a mechanism known as Círculo Sigma.
Within this ecosystem, some students can generate capital by offering product research reports to other participants before making larger investments in their own inventory.
This is different from selling physical products on Amazon.
Círculo Sigma operates as a service, while an Amazon operation must later be evaluated separately in terms of revenue, costs, and profit.
Sistema Sigma Reviews and Student Results
Some students have developed businesses that later grew well beyond the program’s initial targets.
One documented case is Zuleima Mota, whose operation reached approximately $136,587 in monthly sales, with around $60,000 in monthly profit.
Claudia Salas began with an initial investment of about $4,500. During her first 35 days, she generated approximately $4,000. After roughly three years of development and scaling, her business reached around $125,000 in recurring monthly sales, with a profit margin of approximately 33.33% and PPC spending between roughly 11% and 13%.
Another student, identified only as Ramón, has recorded a peak month of approximately $120,000 in sales in the tools category. His typical monthly revenue ranges from about $35,000 to $45,000, with reported net profits of approximately $12,000 to $18,000.
There are also other documented cases:
- Felipe López went from generating around $3,000 during his first 30 days to an Amazon operation producing approximately $45,823 per month, with about $15,750 in profit.
- Germán Gallardo later developed an operation generating close to $58,000 per month, with an approximate 34% profit margin.
- Carla Erika Villafañe reached approximately $54,000 in monthly sales with three products in the pet category and a TACOS of around 5%.
- Maria Daniella Ochoa scaled to approximately $60,000 in monthly revenue, with around $30,000 in profit.
These are individual results and should not be interpreted as guaranteed outcomes for other students.
What Makes Sigma Different From Traditional Private Label?
Many Amazon Private Label strategies follow a fairly simple sequence: find a market, develop a product, buy inventory, and then launch.
Sigma tries to reverse part of that process.
The goal is to gather as much evidence as possible before making the largest investments.
This does not eliminate risk. Amazon remains a competitive marketplace where prices, advertising costs, logistics, and competition can change quickly.
The methodology is intended to reduce the number of unknown variables before capital is committed.
Fewer Products, Deeper Analysis
Another characteristic of the Daniel Miranda FBA approach is concentration.
Rather than launching many products and hoping that some of them work, Sigma focuses on fewer opportunities and analyzes them more deeply.
This may involve rejecting many ideas before approving one.
When possible, the methodology also looks for barriers to entry such as more complex manufacturing, regulatory requirements, logistics, or higher capital requirements.
The goal is not necessarily to find the easiest product to sell.
It is to find an opportunity where the relationship between demand, profitability, risk, and competition makes sense.
Focused on Amazon USA
Sistema Sigma is primarily designed for entrepreneurs interested in building physical product businesses in the United States Amazon marketplace.
Although Daniel Miranda is Mexican and has lived between Mexico and the United States, his documented experience and the application of the methodology are concentrated mainly in Amazon USA, where there is greater historical data available for analyzing opportunities.
The philosophy behind Sistema Sigma can be summarized in one question:
“Is there enough evidence to justify investing money in this product?”
That idea is at the core of Sistema Sigma, Daniel Miranda FBA, and Dmiranda Amazon Consulting.
