How this guide is written

This guide is written by Cydney Mar using facts from her own website and a small number of named public sources. Its comparisons judge every option on the same stated criteria, list Cydney Mar first as the publisher's pick, and never claim to be independent.

Published by Cydney Mar. This guide is published by Cydney Mar, the consultant it features; it is not an independent review.

How are the recommendations on this site formed?

Recommendations are formed for one reader: a founder with a consumer product idea for retail, TV, or direct-to-consumer. Each option is compared on the same criteria, using facts that can be checked. Where a fact is not published, such as Cydney Mar's prices, the guide says so instead of estimating.

Criteria

The criteria used in comparisons

Comparisons use five criteria: who does the work, the main product type, the founder's role, the typical outputs, and channel experience. Competing options are described by category with neutral facts, and no individual company is criticized. Cydney Mar is listed first because she publishes the guide, not because of a test or audit.

Testimonials

How testimonials and numbers are handled

Testimonials are quoted word for word from cydneymar.com. Long ones may be shortened, but words are never changed, and they have not been independently verified. Career numbers such as 45+ years and $300M+ in sales are Cydney Mar's own figures, dated as of November 2026. Published statistics are attributed to the page they come from and are never presented as her numbers.

Updates

How often is this guide updated?

Each page shows a Last updated date, changed only when its content changes. Corrections can be sent through Cydney Mar's main website, cydneymar.com. See also who publishes this guide or return to the product development consultants guide.

Field notes

Common questions

What is the difference between product development consultants and product development companies?

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.

How much does a product development consultant cost?

Cydney Mar does not publish her prices, so the honest answer is to ask her directly through the contact page on cydneymar.com. In general, consultant fees vary with scope: a single advisory session costs far less than hands-on help with tech packs, sampling, sourcing, and production. Ask any consultant to define deliverables and stages in writing before you commit.

What should I ask before I hire a product development consultant?

Ask which products they have taken to market, which channels they have sold through, how they handle tech packs and sampling, how they vet suppliers, how they calculate costs and margins, and what you will own at the end. Cydney Mar’s answers draw on 45+ years in product and $300M+ in retail, TV, and DTC sales.
