Why Qflow?

At Qflow we’re on a mission to build a more sustainable future; providing construction and development teams with the data driven insights they need to deliver productive, profitable and sustainable projects. Our team combines construction experience with software engineering and cutting edge data science to deliver real-time alerts to risks and opportunities during construction.

Our founders Brittany (an award winning engineer) and Jade (environmental scientist with experience working on two of Europe’s largest infrastructure projects) have used their experience in the industry and entrepreneurial training to build an industry changing tool and a world class team. Qflow raised over £1M in seed and grant funding in 2019 and are on track for £500,000 revenue in 2020.

With a total addressable market of £1.13bn in the UK alone, and plans to expand internationally within the next 3 years, this is a unique opportunity to join a team looking to scale rapidly in both reach and impact. Qflow sells directly to construction and development teams, and collaborates with industry partners such as logistics contractors and environmental consultants. Qflow’s first wave of products deliver real-time data on construction processes (including material and waste management), providing new insights generated by our AI tools that have never been experienced in this sector before. You will be providing critical infrastructure with the tools to build more efficiently and more sustainably, whilst also automating hideous admin tasks on-site.
