Who offers loans on startup equity?

Hi all,

I'm looking to take out a $250k loan that uses some startup equity I own as collateral (the FMV of that equity comes in at ~$650k).

For what it's worth, the company is 4-5 years old and isn't a brand name like, e.g., Uber. That's to say I'd expect industry knowledge would be required to fully appreciate the value of the equity (e.g. investor names, usage metrics, etc).

Who offers loans of this kind?

I don't imagine I can, e.g., walk into my local Chase branch and strike up a good loan for this, right?

Thanks!
