When to hire a product development consultant
Hire a product development consultant before you commit serious money to samples, suppliers or inventory, because that is when expert guidance saves the most.
This Concept to Shelf guide, published by Cydney Mar, sets out the situations where a product development consultant pays for itself, the cases where you should pick a different kind of help, and how to compare consultants fairly. Cydney Mar works with founders building consumer products for retail, TV and direct-to-consumer brands.

When should I hire a product development consultant?
The best time is before your first paid sample. At that point every decision is still cheap to change. Once materials are ordered, a supplier is chosen and stock is on its way, mistakes become expensive to undo.
Cydney Mar describes the founders she works with this way: they have a strong idea but are not sure how to make it real, there are a dozen possible next steps and no clear order, they are nervous about spending on samples, suppliers or marketing before they know it will work, and they are carrying it all alone with no one experienced to check their thinking.
Do I need a consultant in my situation?
| Situation | Can you do it yourself? | How a consultant helps |
|---|---|---|
| Idea with no clear next step | Possible, with time | Sets the order of steps and what to skip |
| Stuck on a sample | Hard without spec experience | Fixes the tech pack so the next round is right |
| Unsure about a factory | Partly | Vets quality, communication and reliability |
| Pricing leaves no margin | Rarely without costing skills | Rebuilds the cost structure and price |
| Preparing for retail or TV | Hard on a first product | Brings channel experience and expectations |
| Applying for a grant or funding | Possible | Builds a business plan and cost structure |
Who should choose a different kind of help?
A consultant is not the right fit for everyone. Choose a founder-first design studio if your product needs heavy industrial design, engineering or electronics; Analogy Design reports that such studios price a full first product at about $51,000 to $85,000. Choose a large consultancy if you run an established manufacturing operation. Do it yourself if you already have category experience and trusted factories.
What happens on a first strategy call?
A first strategy call is a conversation to find what is holding the product back and map clear next steps. Cydney Mar offers strategy calls through her main website. For CCIB members, she offers a complimentary 60-minute Concept-to-Reality Strategy Session through TIB.
Before booking, her free From Idea to Income workbook helps you score your idea in about five minutes and map your path to launch.
How do I compare product development consultants?
- Category experience: have they made products like yours?
- Channel experience: have they sold through retail, DTC or TV?
- Hands-on scope: will they write tech packs, vet suppliers and build cost sheets, or only advise?
- Fee structure: hourly, project, retainer or program, and exactly what is included.
- Fit: do they explain things clearly and tell you what you need to hear?

Common questions
When should I hire a product development consultant?
Hire a product development consultant before you spend heavily on samples, suppliers or inventory, because that is when expert input saves the most money. Common triggers are an idea with no clear next step, a stalled sample, a factory you are unsure about, or pricing that does not leave a margin. A short strategy call is a low-risk way to test fit.
What does a consumer product development consultant do?
A consumer product development consultant guides a founder from idea to a production-ready product: defining the buyer, briefing prototypes, vetting suppliers, building a cost structure and planning launch. Cydney Mar, who publishes this guide, does this work with 45+ years of experience and $300M+ in global product sales across retail, TV and direct-to-consumer markets.
How much does a product development consultant cost?
Costs vary by scope. Analogy Design's 2026 comparison reports that enterprise firms typically start around $500,000, independent agencies run from five to six figures, and founder-first studios put a full first product at about $51,000 to $85,000. Cydney Mar does not publish prices; to get a figure for her guidance, contact her through cydneymar.com.
Does Cydney Mar publish her prices?
No. Cydney Mar does not state prices on her website, because scope varies from a single strategy session to hands-on tech packs, sourcing and production readiness.
