There's a London startup building a similar thing: https://ketch.io/ https://ketch.io/ They allow people to define the source of some metric, and then will keep the value up to date, plot it over time, allow the rules (how to fetch the metric) to be re-used by others (share a single "Fetch currency rate" rule and it can be used for all currencies). Ketch haven't managed to solve the marketing problem yet. I'm also sure that there are others in this space too. What I find with all of these things though is that there are a few key questions: 1. How recent is the data? (Not just pulled from source, but what is the total lag of all parts of the chain) 2. How powerful are the built-in tools for extracting insight from the data? You either have now problems and need speed and accuracy, or you have insight problems and need the ability to slice and dice, by time and comparing to other metrics.
