Callsign raises $35 million series A


We’re beyond stoked for none other than our TechHub members Callsign, who have just raised an impressive $35 million Series A investment led by global venture capital firm Accel and early-stage investor PTB Ventures.

Callsign is tackling data breaching and cybersecurity with a leading AI-based authentication platform:

“With the proliferation of data breaches, advanced threats resulting in stolen user credentials, there is increasing pressure on companies of all sizes around the world to implement better authentication practices. (...) In response, Callsign developed a deep learning-based authentication platform called Intelligence Driven AuthenticationTM (IDA).”

Founded in 2012 and TechHub members since 2013, they’ve joined TechHub@Campus as a team of 3 only to grow their team to a 50+ count in their London headquarters alone. It has been great to accompany them and be a part their journey throughout these 4 years and we’re very proud of all they’ve achieved, from signing big deals with the likes of Lloyds Bank and Deutsche Bank, to raising a successful seed round as well as signing a big partnership.

Zia Hayat, Founder & CEO of Callsign, said:

“Several years ago, I realised that the way we identify ourselves online was very broken. I knew we needed to make existing solutions like multi-factor authentication and fraud analytics better by bringing them together. Our IDA platform has had an incredible reception from financial institutions, governments and other large enterprises, and this investment will allow us to grow the business and meet some of the strong demand we’re seeing.”

The investment will be used to grow and scale to new markets with a stronger focus in the US.

2017 has been a great for Callsign so far, as they have also announced a partnership with the Global Cyber Alliance in the beginning of the year. A huge congrats!
