> would love any feedback on this.

It's a great feature, however I suspect that you may get too many "I'm flexible" entries relative to how flexible people actually are. In practice I'm probably flexible on equity expectations if a well known engineer/founder wanted to partner with me - or X MM had been secured for funding.

While it might be too much information for a profile, allowing individuals to indicate equity preferences for specific company valuations in their match preferences might guide both parties to the right deal.
