Check the direction before you start building

For companies weighing up an investment in development, taking a project over from another supplier, or wanting an independent check on what their in-house IT or an external supplier is proposing.

First we get clear on who it is meant to sell to and what you are assuming about them. Then I prepare the script, run the interviews with potential customers and write up which assumptions held and which did not, along with a recommendation on whether to carry on at all.

A written document: what I found, what the options are with estimated costs and risks, and what I would do in your position. Written so that it makes sense to people who do not write code.

Yes, I do that regularly. I go through the architecture, code quality, security and running costs. The output is concrete enough to take into a conversation with your current supplier.

The intro call is free. Longer work I charge by the hour or at a fixed price for an agreed scope. You always know up front what you get and what it costs.

No. I do consultations and audits independently of who implements the result. If the conclusion is that your own team or another supplier should build it, that is a legitimate outcome, not a loss.
