I'm Martin Kleppmann, entrepreneur and software craftsman. I co-founded Rapportive (acquired by LinkedIn in 2012) and Go Test It (acquired by Red Gate Software in 2009).

I care about making stuff that people want, great people and culture, the web and its future, marvellous user experiences, maintainable code and scalable architectures.

I'd love to hear from you, so please leave comments, or feel free to .
