Questions & Answers

Who is Yotam Segev and what company did he build?

Yotam Segev is an Israeli entrepreneur who left the Israeli army's most selective program after 10 years to start a company called Ciera, which helps companies find and secure their sensitive data. By 2026, the company was valued at $12 billion.

What does Ciera do?

Ciera is a data security tool that finds every customer record and card number within a company and shows who has access to that sensitive data. The product addresses a critical gap that Yotam identified by interviewing 100 company security heads.

How did Yotam Segev turn around his company's struggling sales?

After a quarter with zero sales, Yotam fired his sales team and began selling the product himself, flying out every Monday night to meet with customers and returning Saturday morning, even while caring for his 10-month-old baby. The next quarter, sales recovered and the company eventually reached $100 million in annual revenue by 2025.
