Just want to point out that Stanford does have its fair share of "MIT startups".
Here's a small subset:
* Alveo Energy
* Amprius
* Blue River Technology
* C3Nano
* Momentum Machines
* QuantumScape
* Solum
Although if the OP's simple model had a category for startups simultaneously validating customer demand and driving technological advantages, most of these companies would be there.
Also, I believe the core of the Google self-driving car team was hired from Stanford after they won the DARPA challenge. At the very least the lead was: http://en.wikipedia.org/wiki/Sebastian_Thrun (I know, not a startup, but it's relevant.)
