It felt like a Heroku moment for me. They have the potential to do to Tensorflow what Heroku did to Rails. Super simple deploy!
Obviously their vision is much broader (with an entire eco-system/'hub', reproducibility, etc.), but to me atleast the first part is super useful and exciting!
One advantage they have is that GPUs are INSANELY expensive on the cloud - they can actually make it cheaper for everyone with clever binpacking and proper termination.
My advice is that in the initial stage, they should partner with all the Moocs to ensure that all deep learning students are using Floyd. It's cheaper, faster and the students can focus on the science. And they provide, 100 free hours!
Disclosure: I've known the guys for quite a while.
