Security breaches, where malicious hackers obtain snippets of information that then get used to impersonate individuals in order to gain access to individuals’ and businesses’ sensitive financial and other private information, have become par for the course in the world of digital services. More than 2.7 billion records were breached in a single incident this year in the US, and overall the damage from incidents like these potentially runs into the trillions of dollars globally.

Today, a startup called Onfido, which uses AI techniques combined with human verifiers to efficiently verify people are who they say they are when using digital services — is today announcing $50 million in funding to help address that ongoing — and growing — problem.

The funding comes on the heels of some very strong growth for the startup, which was founded in London but now operates most of its business out of San Francisco. In an interview, co-founder and CEO Husayn Kassai said that more than half of its customers, and most of its new growth, is coming out of the US.

Onfido uses computer vision and a number of other AI-based technologies to verify against some 4,500 different types of identity documents, using techniques like “facial liveness testing,” to see patterns invisible to the human eye, now has 1,500 businesses as customers, primarily in categories like marketplaces and communities, gaming and financial services, including companies like Remitly, Zipcar and Europcar; and in the last year, it had sales growth of 342 percent. Kassai said that it has to date verified “tens of millions” of IDs.

The money — a Series C2, technically — is coming from a group that includes top strategic tech investors. The round is being co-led by SBI and Salesforce Ventures, with Softbank Group, M12 (the new name for Microsoft Ventures), FinVC and other unnamed new and previous investors are also participating. That’s a signal not just of how the biggest companies in that sector today are grappling with this problem, but also what approach they are using to solve it.

SBI used to be known as SoftBank Investment, although today it goes by Strategic Business Innovator. And to be clear, the Softbank investment in this round is separate from the Vision fund, founder and CEO Husayn Kassai noted, but it’s notable that a lot of the businesses that have been backed out of that fund — companies like Didi, Uber, Oyo, Lemonade, and others — fundamentally rely on people trusting that they are handling personal details securely while also carefully vetting suppliers on the platform (meaning, they need and use services like Onfido’s).

Meanwhile, both Microsoft and Salesforce have extensive enterprise businesses that could see multiple benefits from working with an identity verification provider, not just for their own purposes, but as a service that is sold on to its customers as part of a larger identity management and security offering.

The company is not revealing its valuation but has raised around $100 million to date and Kassai confirmed that it was an upround, with “a lot of happy investors.”

“We have strong metrics, and we have a long way to go in our growth,” he added.

There are a lot of companies today offering services to help offer secure services to authenticate users, for example, to help them log on to their work accounts or to access their online banking services. Onfido’s business focuses on the first step in all of this — customer onboarding — specifically around services geared towards consumers.

The opportunity that has opened up for it has been the result of more than just a rise in breaches. There’s also been a growing realization that a lot of the existing services that had been used for verification are simply not fit for purpose: either they too have been breached — as in the case of some of the bigger credit agencies like Equifax — or are not realistically efficient enough for how many online services run today, such as in the case of in-person verifications. (Onfido claims that its system can make a verification in as little as 15 seconds.)

Or, they are part of the new guard that has shifted its approach to the business of ID verificiation, either by choice or force. One would-be competitor from the past, Checkr, is now a partner of Onfido’s, Kassai noted. Others like Jumio — which is still grappling with the fallout from major illegal missteps from previous management — seem to still be trying to find their feet as standalone businesses.

“Fraud is rising and not going anywhere,” Kassai — who co-founded the company with Ruhul Amin and Eamon Jubbawy — said. “And the problem is that there are a dozen other companies that have not done a good enough job to detect it so far.” While no service is perfect — Onfido says that its “risk exposure” is 0.0195 percent — he says that the advantage of building its service on top of AI means that the algorithms use every experience to continue honing its accuracy. “What we learn from one client gets applied everywhere,” he notes.

“There has never been a more important time for companies to build trust with their customers by showing they are one step ahead of fraudsters,” said Frank van Veenendaal, the ex-vice chairman of Salesforce, who is joining the board with this round. “I believe Onfido has the unique opportunity to transform the digital identity market and deliver robust and scalable authentication-as-a-service, similar to how Salesforce transformed customer relationship management.”
