Stairwell Raises $45 Million in Series B  

by Kay Aloha Villamor in October 13th, 2022

Stairwell, a Mountain View, CA-based company that empowers security teams to outsmart any attacker, announced that it raised $45 million in Series B funding, bringing its total funding to $69.5 million.

The round was led by Section 32, with additional investments from Sequoia Capital, Accel, Lux Capital, Gradient Ventures, and angel investors Eric Schmidt and Michael Ovitz.

This funding will enable Stairwell to scale its flagship product, Inception, to become the most powerful continuous intelligence, detection, and response solution available.

"New vulnerabilities are discovered daily, and continuous monitoring, threat hunting, and response are needed for around-the-clock efforts to secure the enterprise. Our goal is to plug these gaps, while simultaneously strengthening organizations' overall security stack via capturing, storing, and analyzing all executable files across their environment," said Mike Wiacek, CEO, and Founder of Stairwell. "This Series B reflects the confidence investors feel in Inception and Stairwell's mission to enable security teams to take back control of their data and stay one step ahead of even the most advanced attackers."

Following deals with key customers and MSSP partner Cyderes earlier this year, this Series B will enable Stairwell to meet increased demand for new Inception features as malware attacks continue to rise.

Stairwell has increased its headcount by 100% since the Series B round closed, with plans to add significantly more employees this year.

Recent appointments within the company include Brian Lee as Vice President of Marketing and Eric Byrd as Head of Enterprise Sales.
