Sign In App Limited

Sign In App Limited

Sign In App Limited is a UK-based private company that provides a digital visitor management system. The firm was founded to replace traditional paper sign-in methods with an electronic platform that tracks visitors, manages pre-booking, and issues badges. The software is targeted primarily at schools and small-to-medium enterprises, with a focus on child protection and GDPR compliance. The company's core product, the Sign In App, includes features such as visitor photo capture, emergency roll call, and integration with fire alarm systems. It operates as a software-as-a-service (SaaS) model, with subscription pricing per site. The platform covers the UK market, and the firm has no disclosed international offices or product lines in other geographies. There is no public record of external investment or venture capital funding. The firm appears to be a small private enterprise with no disclosed team size or additional vehicles. No principals, founding dates, or recent operational events are publicly available. The company maintains a website and is listed on Companies House, but detailed financial or operational data is not disclosed. The structural differentiator for Sign In App Limited is its narrow vertical focus on compliance-driven visitor management for schools, a niche that separates it from broader workplace management platforms. The firm operates as a standalone private limited company without affiliation to larger groups or family office structures.
