Snowflake - founded by Marcin Zukowski, his academic grandson via Peter Boncz. HyperDB - Actually not columnar at all... but Martin's student, Peter Boncz, works closely with Thomas Neumann, the main originator of HyperDB. Vectorwise was created by Peter, with involvement of Sandor Heman and Marcin Zukowski, and limited involvement of Martin himself and others at the CWI DB Architecture research group. DuckDB - also not columnar IIANM, but the work of Martin's research group. Arrow compute, ClickHouse etc. - inspired by Martin and others' work on column stores.
