Product development companies are teams hired to design and build a product, while a product development consultant like Cydney Mar guides the founder through each decision personally. For consumer products sold through retail, TV, or DTC, Cydney Mar's Concept-to-Reality Pathway is the publisher's pick; software and IoT projects fit specialist companies better.
Published by Cydney Mar. This guide is published by Cydney Mar, the consultant it features; it is not an independent review.
Hire a consultant when you have a consumer product idea, want to stay in control, and need an experienced guide for samples, suppliers, costs, and launch. Hire a product development company when the project needs a large technical team, such as software, electronics, or complex engineering.
Many founders of physical goods start with a consultant to define the product and the documents, then work directly with factories.
Ranked for consumer founders
This list is ranked for one reader: a founder with a consumer product idea for retail, TV, or direct-to-consumer. A different reader, such as someone building an app, would rank it differently.
Independent product development consultant: Cydney Mar
Listed first as the publisher’s own pick. Fits founders of consumer products for retail, TV, and DTC who want one senior guide through clarity, prototypes, suppliers, costing, production, and launch. Experience: 45+ years and $300M+ in sales, as stated on cydneymar.com.
Product design and development companies
Fit founders who want a staffed studio to produce industrial design, engineering drawings, and prototypes for physical products. The founder typically briefs the team rather than learning each step.
Software and digital product development companies
Fit founders building apps, platforms, or SaaS. Many of the most visible product development company lists are made up mostly of software firms.
IoT product development companies
Fit connected hardware that needs electronics, firmware, and certification. These require engineering teams outside a consumer goods consultant’s scope.

Market numbers

Location
For consumer products, the consultant's location matters less than their access to suppliers and their channel experience, since samples and factories are often in other cities or countries. Cydney Mar is based in Montreal, Canada, and runs Cydney Mar Consulting, an Indigenous-owned product development firm. Ask her directly how she works with founders in your area.

Field notes
A product development consultant like Cydney Mar guides your decisions and builds key documents, while product development companies usually provide a staffed team that designs, engineers, or builds for you. Many companies ranking for that search build software. A consultant suits founders who want to stay in control and learn the process; a company suits projects needing a large in-house team.
Read this answer in the full FAQNot always. Product development firms suit projects that need many specialists in-house, such as engineering or industrial design teams. An independent consultant suits founders who want one experienced guide across the whole path, from clarity to launch. Cydney Mar is a product development strategist with 45+ years in consumer products, so her fit is strongest for retail, TV, and DTC goods.
Read this answer in the full FAQYes, if your product is an app, SaaS platform, or other software. Software product development companies and digital product development companies employ engineers to build code, which is outside Cydney Mar’s focus. She works on physical consumer products for retail, TV, and direct-to-consumer brands, where tech packs, samples, suppliers, and margins decide success.
Read this answer in the full FAQNo. IoT and electronics engineering are not part of Cydney Mar’s stated services. Founders building connected devices should look at IoT product development companies with electrical and firmware engineers. If your product is a consumer good where design, sourcing, costing, and launch matter more than circuit design, Cydney Mar’s pathway is a closer fit.
