Prove helps companies manage their customers’ digital identities by using mobile phone data.







Growth Rate (y/y)








Revenue estimated using publicly available information.

Prove made $109M in 2021, a 90% increase over 2020. Prove’s revenue has grown at 90% YoY over the last 4 years. It has 1000+ customers, with banks as the largest customer segment, followed by healthcare and retail. Fintechs made up 53% of the new business in 2021.



Prove's competitors by revenue and revenue growth. Bubble size indicates valuation. Figures estimated using publicly available information.

Prove has raised $221M from investors such as Relay Ventures, Synchrony, TransUnion, and American Express Ventures. It was last valued at $537M, pegging its valuation/revenue multiple at 4.7x. Socure is one of the highest valued identity verification companies. It has raised $648M with a valuation of $4.5B for a valuation/revenue multiple of 45x.

Prove's multiple is comparable to its publicly-listed competitors. For instance, Riskified, with $229M in revenue and $856M in market cap, has a multiple of 3.7x. TeleSign, which intends to go public through SPAC, has a multiple of 3.4x with revenue of $386M and a $1.3B valuation.

Business Model

Prove’s business revolves around the proprietary dataset of identity information keyed on mobile phone numbers that they’ve built by aggregating data from mobile network operators such as AT&T and Verizon, credit bureaus such as TransUnion, and other third-party sources.

For each of the more than 1 billion consumer and small business identities in their database, Prove can supply information on things like name, address, location, SSN, and email.

Prove then makes that data accessible via API, which banks, fintechs, marketplaces, and others pull into their apps to:

  • Increase conversion rate on signup by auto-populating new user information, instead of asking users to fill out long forms.
  • Improve marketing automation by keeping customers’ contact information up-to-date.
    • Mitigate fraud by checking identity fraud risk before greenlighting a transaction. 
    • Prove makes money by charging companies to access its digital identity database. When companies link the customer profiles in their CRM to Prove’s database, they pay Prove a monthly fee for every linked profile. This SaaS-style pricing model makes its revenue predictable, compared to a usage-based pricing model.

      Prove also earns revenue from multi-factor mobile authentication services where it charges per unit of communication sent, such as text SMS, voice SMS, or mobile push notification.

      Prove's digital identity database revenue is higher margin, as seen in the case of Prove’s competitors, compared to revenue from mobile authentication services.



Prove started out life as Payfone, a mobile payments company, but pivoted in 2015 to digital identity verification. 

Prove offers three products, Pre-Fill, Identity Manager, and multi-factor authentication



Pre-Fill helps companies improve conversion rates by auto-populating users’ personal information instead of asking them to type it out.

Users enter their phone number with their SSN or date of birth at signup, which Prove uses to return other personal information and assess the chances that the signup is related to identity fraud. Prove also runs KYC checks with respect to things like sanctions, AML watchlists, and politically exposed persons.

Identity Manager

Companies can connect customer profiles in their CRM with Prove’s database using the Identity Manager. Once connected, Prove enriches customer profiles by adding missing personal details and keeps the profiles fresh by adding/deleting information as needed.

This enables companies to improve the deliverability of marketing communication such as SMS and emails with up-to-date contact information.

Multi-factor Authentication

Prove's MFA solution comprises standard text or voice-based OTPs, instant links on messages for verification, and push authentication that uses app notifications to verify users are who they say they are.



Prove competes with two types of companies.

One category is fraud prevention companies that focus on helping businesses avoid identity fraud. This category comprises companies like Trulioo, Socure and Ping Identity as well as all-in-one fraud prevention platforms such as Sift and Kount that cover other fraud types such as check-out and policy abuse fraud.

Another category of competitors are companies focused on improving the customer experience by reducing disruptions in user journeys. This category includes all-in-one solutions such as Riskified, Bolt and Forter as well as identity fraud solutions such as TeleSign.

Fraud prevention


Trulioo is a key player in the identity proofing market with a valuation of $1.75B, backed by Goldman Sachs, Citi Ventures, and American Express Ventures. Like Prove, it has a database of 5B identities drawn from 400+ third-party sources that its customers use to verify user identity.


Socure is one of the largest companies in the digital identity verification market with a valuation of $4.5B. It has raised $647M from Bain Capital Ventures, Tiger Global Management and T. Rowe Price. It provides a number of identity verification products such as document verification, identity fraud prevention, compliance and email/phone risk scores.

Kount (part of Equifax)

Kount started as a digital identity management platform that expanded into other types of fraud, such as payment and bot detection. It raised $80M from CVC Capital Partners before being acquired by Equifax in 2021 for $640M. Kount has the upside of integrating its digital identity database with Equifax’s physical identity database for identity management.

Customer experience


Like Prove, TeleSign uses phone number-linked data to enable its clients to ascertain the identities of their users. It made $386M in 2021 and covers 85% of the North American population with a strong presence in Latin America, Middle East Asia and Asia-Pacific. TeleSign has announced plans to go public through SPAC at a valuation of $1.3B in the second quarter of 2022. 

Bolt is a checkout-as-a-service provider for medium to large ecommerce merchants. Boltʼs primary product is its wrapper around the checkout, providing a one-click experience at the consumer end while enabling merchants to maintain control of the customer experience. Bolt makes it easy for users to transact online by letting them save their personal details once and reuse it across different websites. 


Riskified is one of the largest online fraud detection companies focused on ecommerce, having raised a total of $229M. It processed $89B GMV in 2021. It covers different types of frauds such as payment, identity, and policy abuse frauds. Riskified listed in July 2021 at a $4.3B market cap.

TAM Expansion

The big trend driving the identity fraud prevention market is the shift from offline to digital across retail, banking, and healthcare industries. For instance, ecommerce is expected to reach 25% of all US retail sales in 2025, compared to 14% in 2020. Similarly, digital-only banks are expected to cover 20% of the US population in 2025, from 11.4% today. This shift was accelerated by COVID when both public and private entities moved to digital transactions.

Another trend is the smartphone becoming the default device to access digital services. This is being driven by falling prices, faster networks with 4G and 5G connectivity, and the generational shift to digitally native Millennials and Gen Z.

This digital shift has led to an increase in identity thefts and cyber attacks. Neobanks have twice the fraud rate compared to credit cards and three times higher than debit cards. In 2020, identity fraud caused $56B in losses across all US financial services firms.

The convergence of these three trends means that companies are constantly looking for better ways to verify identities and prevent identity fraud, which helps companies like Prove.

Using Pre-Fill for checkout

Prove's Pre-Fill product is used for new user registration but can be expanded downstream to other parts of the customer experience, like checkout. Creating a new user account is one of the top two reasons for cart abandonment in ecommerce websites leading to $18B of lost sales. An ‘auto-fill with Prove’ button can create a new user account in the background when the user checks out without any active input from them, and in turn, the company can get information valuable for marketing purposes.

Geographic expansion

Asian and Latin American markets have sizable populations of mobile phone users—India (490M), Indonesia (170M), Brazil (118M), and so on. Mobile phones are the only computing device for most people in these countries. They use them to access online services such as banking, ecommerce, and healthcare, making mobile-based identity even more important for private and public entities, and marking a significant expansion opportunity for Prove.

Biometric verification

Prove recently acquired UnifyID, a provider of passive authentication and mobile-based behavioral biometrics. UnifyID’s SDK integrates with apps and uses the phone’s sensors to map a user’s behavioral traits such as how they walk, speed of walking, and how they use their phone. It uses this data to verify user identity standalone or in conjunction with multi-factor authentication.

Mobile-based biometric verification is one of the fastest-growing trends in identity verification, where the user doesn’t have to actively send an input. By the end of 2022, 70% of the organizations implementing biometric identity verification will use mobile phones rather than any other device, up from 5% in 2019.  


Lack of document-centric risk identification 

As online theft of personally identifiable information (PII) increases, some companies and governments are moving towards document-centric identity verification using ID card images and selfies. Prove provides multi-factor authentication through OTP but doesn’t have a document-centric verification solution, which may impact its adoption for high-value, high-risk transactions in the long-term. 

Competition from big tech companies

Large companies in adjacent markets offer their own version of pre-fill as a feature, often based on robust identity verification. For instance, Apple offers pre-fill based on biometrics, Plaid using bank data, and Bolt by reusing credentials entered once across different websites. These providers have a larger view of user journeys than Prove, giving them access to better quality user data.
