I think it is great to see products. And I think it is a strong indicator the concept is building and achieving something tangible.

They just launched their beta, and it is great to see the project come to fruition and making steps towards a real product with this beta prototype. check out for yourself https://blog.digipulse.io/digipulse-beta-update-900992f68c0a
