Charts show datasets collected from the website Crowdcube.com
The charts are investement data derived from different company profiles (startups) during their campaigns on the crowdfunding platform Crowdcube.com. The timelines on all charts are drawn to match the period 5 Jan 2016 to 3 Feb 2016.
The Ethos profile (a health studio - website, a brief on the project is also available - investment brief) has the most interesting activity as being the main focus of the project. The other profiles have missing intervals being added in hindsight and dependent on available data (due to their campaign start and end times).
The data was sourced by polling the html, every few minutes, from respective profiles. Here showing a representative display of such data as it appears in the browser.
The central figure is the total money raised, in this example £558,400. Together with other data points;
"investors so far" and "last investment" a transcript of events can be made.
