Our Story in a nutshell

We left our high executive positions in large corporations on a mission to liberate employees (and ourselves) from the agony of information overload.

Knowmail was founded in 2014 by Haim Senior, Oded Avital and Avi Mandelberg. As executives working in a big corporate firm, Oded and Haim were frustrated by the constant need to monitor their emails in order to stay on top of their game.

Over lunch one day, both Oded and Haim realized they were investing excessive amounts of potentially productive time reading often unproductive and irrelevant messages. Together, they realized that if they cannot stop the message flood, they should be able to apply a personalized filter that would allow only relevant and important messages through.

From this realization, the idea for Knowmail was born! Building from their experience, Oded and Haim further developed their idea. After bringing Avi into the picture, they built a team of passionate programmers to build Knowmail – a sophisticated and holistic system meant to free employees from tiring and useless communication granting them more productive time while improving their work/life balance.
