“We strive to be the neutral data company that everyone can work with and trust. Data has generally been seen as a side effect in computing, the exhaust generated by software that is often ignored. We see data as a whole separate layer that everyone should be able to tap into to solve everyday problems. If all data was clean, trusted, and accessible, innovation would thrive and the most positive actors in our society would be rewarded.”

— Gil Elbaz, Founder and CEO
