Enterprise implementations are usually covered by confidentiality terms, and we treat client information as confidential by default whether or not a separate agreement is in place. That produces an awkward tension for a portfolio page, and the honest resolution is to describe the work rather than to name the client.
So each entry sets out the sector, the systems involved and the scope of what was delivered. Where a client has approved being named, we name them. Where they have not, we do not, and we will not imply a relationship through a carefully placed logo either.
We also do not publish performance statistics. Figures like a percentage reduction in close time depend on baselines only the client can verify, and quoting them without that verification is closer to marketing than to evidence. Describing the mechanism is more useful and can actually be checked in conversation.
If you want to speak to a reference, ask. We approach clients individually for permission rather than keeping a standing list, which takes a little longer and is the reason those conversations tend to be candid.
