Klipfolio

Get started quick and easy. Ready-made dashboards and connectors to a lot of databases etc. If that is not enough, you can easily create own datasources (I use Excel, ODBC and Google Drive) and you can build both simple and advanced dashboards with the KPI's that are relevant to you.

I have yet to find any real Cons. I would love to have ready database connectors to the CRM and ordersystem, that we use but as I have already build a source myself, this is really not a "must-have".

I like how Klipfolio integrates well with complex data sources. The user interface is awesome and makes it easy to navigate around the Klipfolio dashboard very easily.
I like the help support team behind Klipfolio ,as they are always helpful and are available at every time of the day.
It offers us CSV based themes ,which enable us better visualize and modify data around the dashboard.

Klipfolio has a long learning curve .Requires a new user to really stay committed to it every minute of the day ,maybe for the first three month.However the effort is worth it.

Once a dashboard is made, it looks great. The UI is really pleasing, and there is a wide range of visualizations to choose from making it easy to convey data in just the right way.

Getting data into the system can be a pain, and manipulating the data is a challenge. It often makes more sense to pre-process the data somewhere else which adds another step in the complexity.

Biggest pro is the number of connectors. Klipfolio connects basically to every tool we use.
Almost equally important is the flexible access to data. This means Klipfolio isn't so dependent on the formatting of the raw data. When I import data for a custom klip, it's easy to select the data the way I want to and represent results in different ways.
I've been able to construct neat and comprehensive dashboards for many different data needs of a game company including marketing data, game performance data, in-game event data and company work flow.
Less is more in the design. This tool is clearly for data visualizations, so that's what you do with it. All other options in settings, team control etc. are minimalistic and simple as they should be.

Honestly, with a few weeks experience, I haven't jumped into anything that would have caused frustration.
Perhaps it could be stated that the pricing plans push even relatively small teams to go for more expensive options.
