CTOs and procurement leaders locked into a single-vendor AI stack with rising cost and no exit.
We do not cut over until the new stack passes the same evaluation set as the incumbent, side by side. Parity is proven on your own data before the old contract is touched, so the switch is measured rather than hoped for.
Single-vendor is the right call early, when speed beats optionality. It becomes a liability once spend is material and the vendor holds your prompts and data; at that point portability is leverage on price and a hedge on the fastest-moving market in software.
