Private money loan and CA usury law

As a rehabber, I'm willing to borrow money at more than the usury-limited rate of 10% (I live in California). I have seen posts in the past indicating that private money can be loaned at higher interest rates if the borrower is a company (we have an LLC). However, I have done a bit of searching online and I have been unable to find applicable California law that would corroborate this. Does anyone know if this exception is actually true, and if so, can you please point me to the corresponding law explaining it?

Thanks for any assistance!
