If the company is on the verge of closing, clearly there is something wrong with the business model. So for it to actually save jobs they have to first have the 1.7 billion that Amazon was going to pay and then have enough capital and a business reason that makes the acquisition make sense.
There are not many companies like that out there, particularly for a company like iRobot. There was synergy between iRobot and Amazon.
I am not advocating for a monopoly, but clearly another company wasn't stepping up to take amazon's place.
