My better half made me complete this personality test last year and it opened my eyes to the different types we all are. I think this is especially important in early-stage ventures and partnering up.
It would probably save a lot of heartache in finding out if we're compatible with our potential cofounders before we signup together.
FYI, the test shows I am an Architect, which is absolutely spot-on - I love envisioning, architecting, designing and building new digital startup business ideas. Which is now exactly what I try to offer as an early-stage interim cofounder/cto at www.steveprocter.com
Go on give the test a go and let us all know what type you are.
