Founded in 2014, OnePulse, which has offices in Austin, Texas, and London, the UK, will use the investment to expand its services into new markets.

Users of the platform can conduct surveys of up to three questions at a time and receive responses from targeted audiences using a gamified mobile app. Clients include Coca-Cola, TikTok and Marks & Spencer.

The platform currently offers access to consumers in the US, UK, several European countries, China, India, Australia, Canada and Kenya. OnePulse is planning to expand this to cover Russia, Mexico, Brazil and more countries in Europe.

The company will also use the funding to make further changes to the app and client platform to include more artificial intelligence.

The investors were advised by PwC through its Raise Ventures programme.

Reuben Wilcock, head of ventures, Blackfinch, said: "Mike [Billingsley] and his team are now well placed to reach their goals for growth, allowing more brands than ever before to connect to consumers for near-instant market feedback."

Matthew O’Kane, managing director, Nexus Investments, said: "We are big believers in the power and value of ‘community-generated’ data and insights, and very excited to both announce the 14th new member of our Nexus Scale-Up Fund portfolio, and to partner with OnePulse on its next stage of growth, as it develops its activities and communities beyond those currently in the UK, US and Africa."
