Better.com CEO Vishal Garg has acknowledged to employees that he “personally guaranteed” the $750 million cash infusion provided to the online mortgage lender last November in an email seen by TechCrunch.

Then on November 30, the company announced that blank-check company Aurora Acquisition Corp. and SoftBank decided to amend the terms of their financing agreement to provide Better with half of the $1.5 billion they committed immediately instead of waiting until the deal closes.

But what wasn’t revealed at that time, as Fortune reported last week, was that when SoftBank ponied up that $750 million in November, it was Garg – not the company as a whole – who assumed responsibility for compensating the Japanese investment conglomerate for any losses.
