AquAffirm™ smartphone-based platform for water contaminant testing.

AquAffirm (www.aquaffirm.com) is a UK-based green tech developing proprietary solutions to address current challenges in the management of water pollution around the world.

AquAffirm has developed (and patented) the FIRST smartphone-linked digital sensor and AI-enabled software platform for contaminant monitoring and mapping. Working like a “diabetes test for water”, the tests use specially designed test strips which can be manufactured affordably at scale. Over the coming years we anticipate AquAffirm’s cloud-connected products will be at the forefront of global campaigns to measure, map and manage contaminants affecting millions around the world, saving lives and reducing operational costs for our customers.



Pilot studies to validate the test are now underway in South Asia

AquAffirm’s first sensors are being piloted in South Asia to measure arsenic, a global issue affecting millions and killing hundreds of thousands each year; future products in the pipeline include new sensors for measuring antibiotics in rivers (a ticking public health timebomb) as well as “forever chemicals” known as PFAS (which have received considerable attention in the UK1 and US2 over recent months).

AquAffirm also develops water infrastructure optimisation software which is being launched into UK market later this year.

AquAffirm has an experienced management team and board, including a founder who previously co-founded one of the UK’s early biotech success stores, with a ~$900M exit.
