pico.sh is not new by any means. I was using them ~3 years ago (or maybe even for longer), with their lists.sh service.

After I opened my blog, they launched prose.sh, and rest of the services soon after, but since I settled on my blog, and didn't want to change horses, and they discontinued lists.sh, I had to part ways with them.

I admire what they've built though, and wish them best of luck.
