The group came to us through our capital partner, under NDA, before its real data was available.
We built a private workroom and ran a first working analysis anyway, with every first-pass dollar labeled an estimate until their data backed it.
If you wait for a signature before doing any thinking, the first conversation is about process, not their business. The estimate label keeps anything from looking like fact before it earns it.
In a working session the client argued with a live scoring model. The introduction became a signed 90-day operating audit in 18 days.
A client arguing with your model is already inside the work. Show up with something they can fight.
