Judge launch experience by what an agency does before the launch, not by how many launches they claim. Ask for the research file: market size, growth trajectory, return rate, rating gap, segment dynamics. We run 90 or more data points before committing capital. Volume of past launches without that discipline is just volume.
The short version
- Research depth is the credential. Anyone can list launches. Few can show the analysis that preceded them.
- Review count is the laziest metric in this industry. It says almost nothing about whether you can win.
- Differentiation comes from competitor negative reviews. Not from invention, and not from a brainstorm.
- A launch is a capital decision. About $8,000 to $15,000 for one product, $25,000 to $50,000 for a five-product brand.
- Budget about seven months. A brand launch that promises ninety days is describing a listing, not a brand.
You are about to spend real money
If you are reading this, you probably have a product idea or a supplier quote and you are trying to work out whether an agency will improve your odds. Fair question. The honest framing is that you are not buying execution, you are buying a filter. The most valuable thing a launch partner does is tell you which of your ideas should never reach a purchase order.
That reframing changes what you should look for. Execution capability is common. The willingness to talk a client out of a product is rare, because it costs the agency revenue in the short term.
What the research should actually contain
We run 90 or more data points on a category before recommending entry. The headline ones:
- Market size and growth trajectory. Is the category expanding, flat, or being harvested by incumbents.
- Return rate. A category that returns heavily will eat a margin that looked fine on a spreadsheet.
- Segment dynamics. Which price bands and use cases are consolidating, and which are still fragmented.
- The rating gap. Where customers are consistently disappointed by what is already on sale.
- Competitor negative reviews. This is where differentiation comes from. You are not inventing a feature, you are fixing a documented complaint.
The rating gap and the negative reviews do the heavy lifting. A product that solves a complaint appearing in hundreds of one-star and two-star reviews has a reason to exist that you can write on the listing and prove in the images. A product built from a founder's intuition has to create demand, which is a much more expensive job.
The launch economics
| Line item | One product | Five-product brand |
|---|---|---|
| Total upfront capital | $8,000 to $15,000 | $25,000 to $50,000 |
| Phase 1 validation batch | 200 units, $5,000 to $10,000 | Up to four products tested at once |
| Management fee, monthly | $800 | $2,400 |
| Recommended ad budget, monthly | From about $1,000 | Scales with product count |
| Time to a complete brand launch | Shorter, single listing | About seven months |
| Your time commitment | 4 to 6 hours a week during launch | Same, spread across products |
Read the second row carefully, because it is the part most launch proposals skip. Phase 1 is a deliberately small commitment: around 200 units, $5,000 to $10,000, testing up to four products at once. You are buying information about rating, conversion rate, and customer acquisition cost. Phase 2, the real inventory commitment, only happens once those three are proven.
An agency that goes straight to a full container is not confident, it is uninterested in the downside. Ask any candidate to describe their validation phase in units and dollars. If they do not have one, you are the validation phase.
Where the money actually goes
The management fee is usually the smallest line. Inventory, freight, trademark filing, Amazon's own seller fees, photography, and ad spend make up the bulk of it. Any proposal that blurs the fee into the pass-through costs makes comparison impossible, so ask for a version that separates them before you evaluate anything.
How to test claimed launch experience
- Ask for a category they declined to enter in the last year, and why.
- Ask what their research file contains, by name, before they quote you anything.
- Ask what their validation batch looks like in units and dollars.
- Ask what evidence would make them recommend stopping after Phase 1.
- Ask who writes the listing copy and who builds the images, and whether those people are employees.
Question one is the tell. An agency that has never turned down a category either never analyzes one or never says no. Both are expensive for you.
What most agencies will not tell you about launch experience
The case studies you get shown are survivors. Every firm with a portfolio has products that never made it past the first restock, and those are the more instructive stories. Ask for one. Ask what they missed in the research and what they changed afterwards.
The second omission is timing. Full brand launches take around seven months from research to a working catalog, and most of that time is unglamorous: sourcing, samples, quality control, compliance documents, photography. If a proposal implies revenue in week six, it is describing the moment the listing goes live rather than the moment the brand works.
