Chronicle Co-Founder Launches New Cybersecurity Company Stairwell

Newly launched cybersecurity company Stairwell, which aims to provide security teams with more tools to identify adversaries, has closed a $4.5 million seed investment round.

The new organization is founded and led by Mike Wiacek, who previously founded Google’s Threat Analysis Group and co-founded Alphabet’s enterprise security firm Chronicle. Jan Kang, former chief legal officer at Chronicle, joins Stairwell as COO and general counsel.

Stairwell has shared very few details about its products, but described them as user-centric tools designed to help security teams “understand the pivotal relationships between their external and internal data sources,” thus helping them proactively combat cyberattacks.

“Security teams today are beholden to siloed tools that cannot identify ambient connections between their external and internal data sources and provide only baseline level protection against generic threats. We started Stairwell so security teams have a cohesive understanding of what’s good, what’s bad, and why, so they can actively defend against the most sophisticated threats,” Wiacek said.

The funding round was led by Accel, but also saw participation from Sequoia Capital, Gradient Ventures, and Allen & Company LLC, as well as from other angel investors.
