Common questions
Short answers below. The full product development FAQ answers 48 founder questions.
Should I hire a product development consultant or a firm?
Choose a consultant when you want one experienced person guiding your decisions across every stage; choose a larger firm when you need a full in-house engineering or design team. Many consumer product founders need judgment and sequencing more than headcount. The comparison page on this site sets out the trade-offs on the same criteria.
More answers in the FAQWhat does a product development consultant do?

More answers in the FAQHow much does a tech pack cost?
Published comparisons put freelance tech packs at about £30 to £200 per pack depending on complexity, according to a 2026 Fabrickly comparison of tech pack companies. The same article notes that quality varies. Cydney Mar does not publish prices for her tech pack work, so contact her through cydneymar.com for a quote.
More answers in the FAQWhat is the difference between roadmap and strategy?
A strategy says what you are trying to win and why, while a roadmap says what you will do, in what order, to get there. For a product founder, the strategy covers the customer, the channel and the margin you need. The roadmap turns that into concrete stages: define, prototype, source, cost, specify and launch.
