Product development agencies

What this covers on a directory of web agencies

The majority of these listings mean digital product work: taking a software idea from concept through discovery, prototyping and build, with the ongoing iteration that follows. On an ecommerce site that usually means a tool the store offers customers, an internal operations system, or a platform the business intends to sell.

A minority mean physical product development — industrial design, prototyping and manufacturing liaison. That is a different profession, and where an agency genuinely offers it they will have a portfolio of objects rather than screens. Ask to see it.

If it is digital product work

• Buy discovery separately. A short, paid discovery that ends with a scope, a cost and a recommendation — including possibly “do not build this” — is the cheapest risk reduction available. Agencies that skip straight to a fixed build quote are pricing a guess.
• Ask what happens to the team after launch. A product is not finished at launch; it is barely started. An agency structured entirely around projects will disband exactly when you need continuity.
• Insist on owning everything. Code, repositories, infrastructure accounts, designs, and any third-party accounts created for the project.
• Agree how success is judged, in terms of what users do, before the build starts rather than in the retrospective.

Questions worth asking

• What did you last ship in this category, and is it still running? Products that quietly died after handover are the relevant history.
• How do you handle changing requirements? Fixed scope and product development are in tension; something has to give and it should be agreed which.
• Who will use this, and have you spoken to any of them?

What it costs

A paid discovery phase is commonly $5,000–$25,000 and should produce a decision. Initial builds of a focused digital product typically run $50,000–$250,000. Physical product development is priced quite differently — usually in phases with tooling as a separate capital cost — and is outside what most listings here do.
