Diagnose before you shortlist. A launch fails through weak product selection, underfunding, thin traffic, or refusing to stop when the data says stop. The right agency is the one that fixes your specific gap and can tell you, in writing, what would make them advise killing the product.
The short version
- Match the agency to your failure risk, not to their best case study.
- Four gaps sink launches: the product, the capital, the traffic, and the discipline to stop.
- The stop question is the interview. Ask every candidate what would make them tell you to end the launch.
- A launch partner without research capability is a media buyer with a nicer deck.
- Written gates beat enthusiasm. Yours and theirs.
The diagnostic: which launch problem are you actually hiring for
Launch agencies are not interchangeable, because launches do not fail in one way. Run your situation down this table before taking a single sales call.
| Symptom you can observe | Underlying cause | What the right agency looks like |
|---|---|---|
| Great product ideas, no idea which will sell | Selection gap | Deep research capability, market sizing, a documented method for choosing |
| Confident in the product, fuzzy on budget | Capital planning gap | A partner who itemizes the launch cost before signing, and declines if it does not close |
| Product live, sales trickling | Traffic gap | Multi-channel execution capability, not just sponsored ads |
| Spending steadily on a product that never improves | Discipline gap | A partner with explicit stop criteria and a record of using them |
Most sellers instinctively hire for the traffic gap because it is the visible one. In my experience the selection and discipline gaps destroy far more capital, they just do it quietly, over quarters instead of weeks.
The interview question that sorts agencies fastest
Ask each candidate: under what conditions would you tell me to stop this launch?
You will get three kinds of answers. The most common is a deflection, "we iterate until it works", which means your budget is the iteration fuel. The second is a vague gesture at reviewing performance quarterly. The rare third kind is specific: named metrics, thresholds, and a time window, agreed before launch.
We hold ourselves to the third kind, and I can tell you where it came from. Early in my selling career I kept a failing product alive for three months, pouring money into advertising and waiting for the turnaround. It never came. The tuition from that mistake became our scale, fix, or kill gates: we watch the rating trend, returns, conversion, and where acquisition cost is heading across a defined window, and the product either earns its next phase, gets a targeted fix, or ends. An agency that carries something like this is protecting your capital. An agency that does not is billing against your hope.
The rest of the shortlist test, in order
- Ask how they decide a product is worth launching at all, and make them show the analysis on a real example, anonymized is fine.
- Ask for the full capital picture: inventory, freight, advertising, fees. A single-product launch realistically needs $8,000 to $15,000, and a partner who will not discuss the total is hiding the hard conversation.
- Ask who executes each part, research, creative, campaigns, and where those people sit.
- Ask what the first bad week triggers. You want a monitoring cadence and a decision process, not reassurance.
- Ask what happens if you leave mid-engagement. The right answer includes your account, your campaigns, and your creative staying with you.
An agency that clears all five is rare. Two failures is a pattern; walk.
What most launch agencies will not tell you
The launch business model rewards optimism. An agency paid monthly earns nothing extra by advising you to stop, but it earns continuation by keeping the launch alive, so the industry default is a permanent "almost there". This is not villainy, it is incentive gravity, and the counterweight has to be structural: stop criteria in the statement of work, a flat fee that does not grow with your ad budget, and month-to-month terms that let you act on what you see. Our tiers are structured exactly that way and published on the pricing page, and I would hold any agency, us included, to those three structural tests before trusting their launch enthusiasm.
