It is VC backed IE so you wouldnt have been able to invest at that early stage . That said I was in fact was one of the first 20,000 users of Slack, moved my entire company and team onto it in early 2014. Feel in love with the product immediately as it allowed our teams to really connect. I have also worked with the Canadian firm which essentially designed the user interface and user experience of first version of slack and they put me onto it - metalab http://metalab.co/

I know how to pick exceptional product experiences and design and don't really see why Reffind would be of value.

FYI This early video with Slack's founder is worth a watch (from time shortly after launch) asI'm a regular watcher of "this week in" as you get on the inside of the newest solutions and stay way ahead of the curve and everyone else in Australia who act like they know about technology.
