Bluephage's, patented, microbiological testing kits developed at University of Barcelona, easily detect Coliphages in water (newly recognized as viral indicators of un-safe water). Distributing to 15 countries globally, Bluephage are well placed to enter the €1.4 billion (2022) water testing market.

  • Bluephage is the 1st water biotech company in Spain to become a B-Corp
  • Commercializing patented technology, licensed to us by University of Barcelona
  • Our coliphage, water testing kits help prevent water-borne diseases
  • Distributing to 12 EU countries, Singapore, South Africa & Georgia


Bluephage was founded in 2016 as a spin-off from the University of Barcelona by renowned researchers from the Health-Related Water Microbiology Research Group (MARS).

Our goal is to help fight the global water crisis & becoming a B-Corp only helped to reinforce this.

In 2021, the European Commission recognized Coliphages as a new, viral indicator within water. Water free of Coliphages generally can be deemed safe. With this patented, disruptive technology, licensed to us by University of Barcelona, you can detect Coliphages in just 6hrs. This is critical in a global context where rapid testing can help save lives, and where water safety is a key driver of policy making.

Over the last year we've gone from focusing on R&D to commercializing a product that quickly tests water for Coliphages. We've raised over €1.3m through two private rounds and several public grants. We're expanding our distributor network internationally with a presence currently in 12 European countries, Singapore, South Africa, & Georgia. Further, Our work in this area has already been recognized by Water Europe, who awarded us their '2020 SME Innovation Award'.

We're now ready to launch the 'Rapid Kit' to wider markets and hope that the Crowdcube community will help us in distributing this technology to ensure safe water for a better world.

For everyone, for the planet, help us fight the water crisis!

As with any investment, investing in Bluephage carries a level of risk. Overall, based on the key risks highlighted below, the degree of risk associated with an investment in Bluephage is higher than in a company that's trading on a public market.

Early-stage investmentEdit

Bluephage is at one of the earliest stages of the business lifecycle, and the failure rate of companies at that stage is usually much higher than those at a later stage.

Illiquid investmentEdit

The number of transactions in shares of private companies is usually significantly lower than in public companies, typically resulting in it taking longer to sell shares in private companies at a price that is at least equal to the price that the shares were bought at. Accordingly, the Bluephage investment opportunity is considered to be higher risk than more liquid companies.
