Cumul.io

1) Simplicity
Cumul.io offers a simple workflow offering only two views: datasets - where you add or alter the data; and dashboards - where you create stunning drag & drop dashboards. As a responsible for the product, I am focused on creating an easy to use dashboard for our customers. As a non-technical user I find it easy to create a custom dashboard that my technical colleague finalizes.

2) Security features
As we are involved with treating sensitive data, we value a robust & technically secure solution. The cumul.io authentication system allows us to ship a product knowing that each customer will see its own data and that everything is behind closed doors, as it should be.

3) Customer support
The direct connection with the support team is beyond incredible. I wish other companies would take a look at their workflow to become half as good as Cumulio :).

1) Visual features
Visual features could be improved, although the product is improving with every update. It goes for both using texts, sizing etc as for graphs which are sometimes too limited. On the positive side: this is clearly improving.

2) Copy paste
Using copy paste between different dashboards is non existing. This makes it sometimes frustrating to re-create something in a dashboard, knowing you have done it before already. It does not happen that much luckily ;).

It's very easy to embed in your own product. No hassles of setting up an entire infrastructure like many of their competitors require.

In the beginning they had no version control and multi language option. That was a pain, but they do have them now and they work well.
