Contributors and sponsors


Over its more than two decade of development, many people have contributed to the development of MonetDB, as architects, code developers or as guinea pigs, while developing applications on top of the often fragile development code base. MonetDB wouldn't have come to life without this dedication and involvement. Their names should be engraved in stone, but bits is all we have. Nameless and countless, but equally important are the people on the mailing lists, challenging us with bugs, feature requests, and being happy users.
