Evolv Technologies Holdings, Inc. engages in the manufacture and development of security screening products. The company is headquartered in Waltham, Massachusetts and currently employs 293 full-time employees. The company went IPO on 2020-02-29. The firm is developing artificial intelligence (AI)-based weapons detection to create safer experiences for venues and companies as well as schools, hospitals, and public spaces. Its touchless security screening solutions use AI software, software-as-a-service (SaaS) cloud services, and advanced sensors to reliably detect weapons that could be a threat to a crowd of visitors while significantly reducing nuisance alarms from harmless personal items. Its flagship product is Evolv Express, a touchless security screening system designed to detect firearms, improvised explosive devices, and large tactical knives in unstructured people flows. Evolv Express supports a maximum screening throughput of approximately 4,000 people per hour. The company sells its solutions under two primary sales models. Evolv Technology, Evolv Express, Evolv Insights, Evolv Cortex AI, and Evolv Visual Gun Detection are its registered trademarks.
