It is accurate from the perspective the investors actually made a lot of money out of him. Matt Levine sums it all up very well:

In short his hedge fund tanked, he started some new companies, retrospectively backdated the shareholding of the new company to make his loss making investors from the previous failure shareholders, that company ended up being successful and floated, those investors made a lot of money.
But everything about what he did to make that possible is entirely dodgy/illegal.
