It does not mean we cannot do it: the catalogue covers the most common cases, not all of them. Tell us about yours and in one hour we will say whether it fits.
Tell us your caseThe timelines come from real projects and run from signed specification to go-live. They can be combined: the first solution pays for the architecture and the data model, and every piece added afterwards costs a fraction.

Talk to the client, not to us
We do not publish our clients’ names. What we do, if one of these solutions fits you, is ask for permission and put you in touch with the person who ran the project.
They will tell you what went well, what it cost and what they would do differently. It is the most honest reference we can offer.
Before you decide
Ask to speak to a client before signing anything.
Timelines and ranges are indicative and come from real projects. The exact figure comes out of the assessment, which is contracted at a fixed price and credited back in full against the project.

Bring your case. In one hour we will tell you whether it makes sense.
And before proposing anything, we show you how a company in your own sector solved it. Free, and with no sales deck.
