Expel is a managed security platform that helps businesses identify and eliminate cybersecurity risks. Its software detects threats, provides security monitoring, and connects customers with security analysts 24/7 to hunt for attackers. Founded in 2016 by CEO David Merkel and co-founders Yanek Korff and Justin Bajko, Expel serves enterprise clients like Delta Air Lines, DoorDash, and CDW.

To fuel growth, Expel has raised nearly $290 million to date, including a $140.3 million Series E in 2021 at a $1 billion+ valuation, followed by $31 million in additional Series E funding in 2022. The funding is being used to expand in the UK and European markets. However, Expel recently laid off around 60 employees (10% of its workforce) in June 2023, just 8 months after its latest funding round, citing economic shifts.

As a mission-driven company, Expel aims to attract top security talent by providing opportunities to work with experienced practitioners on a cutting-edge platform to defend against cyber threats. However, the recent layoffs underscore the challenges of operating in a dynamic industry and economy. Prospective employees should weigh the growth opportunities with the potential volatility. Investors should scrutinize Expel's growth metrics and path to profitability as it expands internationally in a competitive market.
