They are very comparable. SF1 and IOT create a technology product. Both have failed to sell enough to become profitable. Both burn through a truckload of cash. Both have had many CRs.

If they didn't buy Stemify, Robo3D with its printer-only business would be dead and buried now because that business model of selling printers was never going to be profitable and was a huge cash sucker. The red flag was when the much larger players in the sector exited the personal 3D printer space.

The addition of Stemify has at least given a very small glimmer of hope that they could breakeven one day. Although, I'd give that a less than 20% chance. The odds are not good, IMO.

Personally, I'd drop the printer making side of the business altogether and just focus on the high margin side of the business, which is essentially the business they bought and which was supposedly making $800k EBITDA when it was acquired.
