About us

Across our towns and cities millions of engineers, cleaners and security guards work hard. Each of them play a vital role in keeping our workplaces, hospitals and factories running. However, much of their hard work goes unnoticed. This is not good. Because work that goes unnoticed goes unrewarded. For example, if no incidents happen overnight why pay for a security guard?

Our software helps these people show customers their value. It wows customers, delights users and reduces admin. Our users work in a range of places from global investment banks to local colleges.

Founded in 2012, SIRV is a specialist team based in London and Johannesburg. Our backgrounds include intelligence, political, computer and data science. 

SIRV stands for Systematic Intelligent Risk Valuation. Thank heavens for acronyms!


In 2012 brothers Phil and Andy began building SIRV.

Andy was the design champion and Phil only cared for function. Andy would claim he and Phil were like two members of a rock band. They would fight for days but would make amazing music as a result. However, Phil liked to think Andy was plain wrong.

By 2015 they had finishing arguing and SIRV was born and it has grown organically ever since. Moreover, today it is available as either ‘off the shelf’ product or as a bespoke solution.
