Mark Suster wrote a great post welcoming Sam Rosen into the GRP Partners fold as their first EIR - entrepreneur in residence - since Mark joined the fund. It is a great article and Sam is an awesome dude (and the impetus behind me starting this blog, as he was the first to recommend putting my advice and learning in writing form).
Take heed from how Sam continued to have touch-points with Mark. He naturally kept the relationship warm and is reaping the benefits. I’m looking forward to seeing what Sam builds. One thing I do hope is that Sam catches Mark’s writing bug- the startup world would have another great entrepreneur-writer.
