- Lastwall
Participated · Series A · May 2026
Lastwall develops IDCommand, an identity verification platform that assesses over 200 characteristics of each login attempt—such as keystroke cadence, mouse movement, and hardware configuration—to prompt additional authentication and alert security teams when anomalous activity is detected. The company pursued enterprise-grade customers from the outset, working with the U.S. Department of Defense and earning FedRAMP Moderate Authorization for use across the U.S. federal ecosystem. Lastwall’s technology is positioned to protect government agencies and critical infrastructure providers across North America, and the company plans to scale its deployments with the new financing. Leadership highlighted the growing threat of nation-state cyberattacks and the expanding blast radius of identity compromise in the AI era as drivers for demand. The company has existing investors including Blue Bear Capital, 18West, and Blue Wing Ventures, and noted the possibility of future fundraising and venture debt from banking partners.
