Hire the Top 1% of Product Development / R&D Consultants

A product development consultant helps you take a product from an idea to something you can manufacture, pass compliance on, and sell. For physical products, that is harder than it sounds. As one operator on this list puts it, shoes are the most complex type of product to manufacture, and supplements and beauty are not far behind. Formula, suppliers, prototyping, quality, and the order you do them in all decide whether the launch works.

What a product development consultant does

The work spans strategy and execution. On the strategy side: deciding what to build, validating the concept with real users, and shaping how each product fits the brand. On the execution side: developing the formula, sourcing and choosing factories, prototyping, scaling production, and standing up the quality and compliance checks that protect your supply chain. A good one also tells you what to keep in-house and what to hand to a chemist, an agency, or a manufacturer. Often the most valuable hour is the one that stops you from picking the wrong supplier or skipping a compliance step that turns into a recall.

What to look for when hiring one

Hire someone who has shipped a product in your category, not just advised on one. Ask what they personally built and scaled, and whether they have lived the messy parts: a failed formulation, a factory that missed spec, a regulator's questions. Category matters. Supplements, beauty, food, and apparel each have their own sourcing maps and rules, and a generalist will miss the nuances, like the difference between running powder formulations and ready-to-drink cans. Look for specific, direct advice over reassurance. The founders who get the most value say their consultant did not sugarcoat anything and broke down the realities so they finally clicked.

Why founders use MentorPass for product development

MentorPass connects you directly with operators who have built and sold real products, not career consultants. The lead for this capability ran product at Dr. Squatch through its $1.5B acquisition by Unilever. Others run a beauty formulation lab, a global sourcing practice, a CPG quality and compliance firm, and their own consumer brands. Most of the demand here comes from DTC and CPG founders, which is exactly who these operators have worked with. You book the person you want, get advice applied to your product, and come back as it moves from concept to launch. No retainer, no agency markup, just time with someone who has already done what you are trying to do.
