The stable marriage problem has two natural algorithms that produce a stable matching: one algorithm give priority to women's choices and one gives priority to men's choices.

This is true under two conditions: 1. Marriages are heterosexual; and 2. Marriages are monogamous.

While startup/VC relationships are heterosexual (err, heterofinancial?), they are absolutely not monogamous, so the analogy to the stable matching algorithm already fails.
