I worked at a sleep company up until 2008 and there are a lot of startups and big sleep companies getting into lowcost devices that a customer would own or rent instead of going into a sleep lab. They would do more diagnosis or pre-diagnosis rather than just wakeup timing but I think some had that feature. I know there is a watch that does this.
One tip I would do if I were them were to contact all those huge sleep lab companies and try to get them interested. Insurance covered prescribed factory sleep labs drive the industry.
I think this is pretty significant advice. My daughter broke her foot one day before getting on a plane to Barcelona, where we planned on doing a lot of swimming, I had a waterproof cast cover over-nighted and they sent two. One for me and a free one for the foot doctor. The product worked so well, it literally saved our vacation and I couldn't say enough good things to the doctor when we got back. I'm sure giving the free sample to the doctor was a win for them, especially considering the doctor had never heard of the product.
