Our take
Security screening systems are essential within venues such as concert halls, schools, and workplaces, but there are several problems with existing solutions. For example, lengthy queues and physically intimidating security checkpoints can taint visitor experiences, as well as cause congestion due to their inefficiencies.
Evolv Technology develops AI-driven screening systems, aiming to remove the tension, intimidation, and friction associated with security screening. It does this with a smart touchless screening sensor for weapon detection called Evolve Edge, in addition to an all-in-one venue security analytics platform called Evolv Express.
Whilst the company does face competition from similar security solutions at high-risk locations such as airports, its ability to serve a wide range of venues helps it stand out. With more than 1,200 customers worldwide and a platform combining proprietary hardware, visitor data, and AI-driven software delivered through long-term subscriptions, Evolv has built strong recurring revenue and durable customer relationships. Continued customer additions and expanded deployments helped drive a 40% increase in annual revenue in 2025, showing just how much the company is growing in the emerging market for AI-based weapons screening.
