Key people at Stairwell.
Stairwell is a cybersecurity company founded in 2019 that provides an AI-powered platform for automated threat detection, hunting, and incident response. Its flagship product, the Inception platform, analyzes every executable file at the binary level to detect and prevent cyberattacks that traditional tools might miss. Serving sectors like financial services, healthcare, and government, Stairwell empowers security operations centers (SOC), incident response (IR), and threat intelligence teams to outsmart attackers by continuously preserving and reanalyzing data with AI enrichment. The company has raised approximately $69.5 million in funding and counts clients such as Fox News, Mandiant, and Sanofi, demonstrating strong growth momentum in the cybersecurity market[1][2][4].
Stairwell was founded in 2019 by Mike Wiacek, a cybersecurity expert who previously co-founded and served as CSO of Alphabet’s Chronicle and founded Google’s Threat Analysis Group. The idea emerged from the need to move beyond passive alerts and instead focus inward on a company’s own data, analyzing files as the source of truth for attacks. Early traction came from the platform’s ability to dramatically reduce investigation times and improve threat detection accuracy, gaining notable customers and significant venture backing from investors like Sequoia Capital, Accel, and Lux Capital[1][2][6].
Stairwell rides the growing trend of AI-driven cybersecurity solutions that shift from reactive, alert-based systems to proactive, data-centric defense. The timing is critical as cyber threats become more sophisticated and pervasive, demanding faster, more intelligent detection and response. Market forces such as increased regulatory scrutiny, rising cyberattack costs, and the expansion of digital infrastructure favor platforms like Stairwell that offer automated, scalable security solutions. By enabling organizations to “run to ground” threats with comprehensive file analysis, Stairwell influences the broader ecosystem by raising the bar for threat intelligence and incident response capabilities[1][4].
Looking ahead, Stairwell is poised to expand its platform capabilities, likely integrating deeper AI analytics and broader threat intelligence to maintain its edge. Trends such as increased cloud adoption, remote work, and evolving cyberattack vectors will shape its journey, requiring continuous innovation. As cybersecurity becomes more critical globally, Stairwell’s influence may grow beyond traditional sectors into new industries, further democratizing advanced threat detection. The company’s commitment to practical excellence and diversity of perspectives suggests it will continue to outsmart attackers and help make the internet safer for everyone[6]. This aligns with its mission to turn security inside out by focusing inward on data rather than passive alerts, fundamentally changing how organizations defend themselves.
