SOLO launches a multi-lateral open banking network

How SOLO’s collaborative network creates a single, living source of truth for financial data.

Hey fintech friends,

Over time, industries move to share data through living networks: Encyclopedias were published by Britannica before Wikipedia open-sourced reference work; resumes migrated from paper to LinkedIn profiles; contact directories upgraded from Yellow Pages to Google Maps.

In each case, networks won out by delivering fresher signals and broader coverage than any single registry could. Networks work because: 1. Record owners are incentivized to keep information current, 2. Provenance establishes trust in information, and 3. Collaboration on a single source of truth scales this trust.

The Dodd-Frank Section 1033 debate in the US is the latest to highlight that consumer data access– whether in financial or non-financial contexts– is subject to questions around who bears the commercial and legal liability for provisioning data.

Zoom out from the open banking debate and there's a bigger question at play: How can we unlock consumers' rights to access all of their data, in every context where it needs to be shared?

Platforms like SOLO demonstrate how a user-permissioned data sharing network can tackle this question to operationalize trust at scale. SOLO enables all open banking participants– from financial institutions to fintech platforms– to access and contribute a wide range of data to a single source of truth on a shared customer. The data becomes portable across the network, with sharing controlled by the end user and usage controlled by the financial institution or fintech platform for their specific workflows, compliance protocols, and products.

Interestingly, SOLO shifts the data furnishing model by enabling financial service providers to be compensated for contributing to users' data– incentivizing data furnishers to maintain and share  verified information across network participants. Launched earlier this year, the network is projected to cover 100 million consumer profiles through its existing partnership contracts by the end of 2025.

Let's dive into the evolution of data portability, how the industry is shifting, and how networks like SOLO rearchitect data sharing for the next era of data access in finance. 

The evolution of user data sharing

Early credit files emerged in the 1800s with local shopkeepers pooling purchase logs to assess customers' creditworthiness. When vendors held different fragments of customers' financial data, centralized credit files enabled trust.

In the past few decades, the Fair Credit Reporting Act enforced standards for credit reporting and later on, the Dodd-Frank Act Section 1033 established consumers' right to access their own data from financial institutions. Open banking APIs and fintech credit bureaus built on these regulations to unlock direct access to user-permissioned data. Meanwhile, financial institutions took steps toward industry-wide knowledge graphs with consortiums like Early Warning Services, DTCC, and The Clearing House's fraud databases– and more recently, fintech infrastructure players launched their own consortiums like Plaid Beacon and Sonar to pool risk signals from more tech-enabled players.

These shared datasets expand visibility beyond single institutions, but each covers a narrow range of data fields and data typically flows in one direction: Out of regulated institutions. The broader constellation of data contributors and platforms accessing their information still lacks incentives to collaborate on a persistent, holistic, single source of truth that can be accessed across institutions. 

"Open banking ten years ago assumed that all the data lived in the banks," explains Georgina Merhom, Data Scientist and Founder of SOLO. "Banks were seen as providers of data and fintechs were consumers of data. The reality now is that both banks and fintechs can be consumers and providers of data. We've moved away from needing  one directional data portability to an ecosystem where trust can move both ways."

Today, our financial lives don't fit neatly into the old categories. Your "primary" financial relationship might be with your bank, but meaningful data also lives with your BNPL provider, your accounting provider, your budgeting app, your rent payment platform, and your eCommerce gateway. 

But lenders' policies, compliance frameworks, and technical systems aren’t engineered for that data to flow freely from your bank to fintech providers and back again. Credit bureau files and bank data feeds carry implicit credibility since regulators enforce compliance with strict processes– but repayment data originated by fintechs, BNPL platforms, or payday lenders outside that traditional regulatory perimeter doesn’t come with audit trails to verify its provenance or data governance.

Meanwhile, every financial provider builds their own user profiles from scratch– even when existing relationships could provide valuable information for customers accessing new services – so financial platforms may end up using 10+ onboarding vendors to screen new applicants' information across thousands of databases for financial data, KYC, AML, fraud, and credit checks…

All for users to re-verify the same information every time they sign up for a new service.

Building collaborative infrastructure

Platforms like SOLO are rethinking data sharing for a world where financial institutions, fintechs, and other data providers are peers in an ecosystem.SOLO is the first network-powered bureau built as a relationship engine– dynamically interpreting workflow context, identifying the specific data elements required, and resolving gaps in financial datasets by orchestrating inputs from both the customer and the network.

As a living, multi-directional network, SOLO’S utility compounds as new customer context is added. Every interaction enriches the network, enabling faster onboarding, more accurate resolution, and a continuously expanding surface of usable data.

The key architectural shifts behind SOLO:

Detects what customer data to collect in different contexts. To bring data into the network, SOLO’s engine reads a financial institution’s or fintech’s workflow requirements, generates a tailored customer data checklist for the event, and scans the customer’s federated knowledge graph across the network. SOLO knows whether each data point has been collected– and which institution it was collected by.

Built as a relationship engine first. Any gaps between workflow requirements and what exists in the network are resolved directly with the customer– creating a new, permanent data asset auditable back to the protocols of the financial platform that originated it. 

Builds data provenance and audit trails. Traditional bureaus and open banking players sit on top of outputs with implied provenance because they come from regulated databases. "SOLO is the only bureau today actually involved in the data collection process," notes Merhom. "We’ve spent the last two years on customer data collection at banks, so we have the audit trail of how data gets into the network stored as lineage that moves with data when it’s shared across institutions, which is how we make the data reusable across the network."

Incentive alignment through compensation. SOLO enables institutions to be compensated for data that’s reused in the network. The compliance work of data verified by one participant becomes a reusable asset across providers, creating powerful incentives: Institutions are motivated to deepen relationships with their customers, contribute more data to the network, and vouch for their customers when data sharing is aligned with sustainable incentives.

Multi-directional data flow. A bank can consume data from fintechs; a fintech can consume data from other fintechs; a lender can see a complete picture of a user's financial relationships regardless of where they originated. The audit trails tracking who originated information and who vouched for its accuracy transforms data from unregulated providers that previously had no "trust signal" into something a regulated institution can actually use.

SOLO addresses this by porting trust as a service– making data from outside regulated institutions usable by establishing clear lineage and accountability in the network.

What data sharing networks unlock

For fintechs and financial institutions, collaborative networks enable:

Speed in user screening. Research shows 3 in 5 users abandon loan applications after 5 minutes. Instead of asking the customer to re-login, or re-enter information they already provided, platforms can surface all user-permissioned data that exists on the customer and is relevant to the workflow at the outset, only asking the customer for consent to re-share and fill in gaps on that occasion, dramatically reducing friction.

Network accountability. When each customer is starting from scratch, there is little protection against customers providing different data points to different institutions. An interconnected network creates accountability between banks and their customers, and between institutions in the network.

Access to services through collaboration. Consumers are at the center of a constellation of every institution they've ever built a relationship with, and are incentivized to contribute to a track record that counts everywhere. 

A user with strong payment history across multiple fintech relationships can carry that trusted record forward– even if it started with a BNPL or credit-builder card– and a living network of continuously updated attestations facilitates real-time decisions around this data.

Monetization without monopolization. Proper incentive alignment prevents any one player from controlling the data flow of the entire infrastructure, while standard-setting protocols compensate value creation, vouch for customers, and foster collaboration across the ecosystem. 

A new era for user trust

SOLO is backed by 100 banks and has both banks and fintech programs participating in its network; as the network scales further, the potential for market-driven collaboration to enable consumer data access compounds.

Just like Google Maps outcompeted Yellow Pages by giving businesses control of their listings, establishing information provenance, and opening data enrichment to a living network, SOLO demonstrates that collaborative sources of truth can scale when everyone is incentivized to participate.

The future of data sharing isn't about building new static information archives. It's about building networks where everyone can contribute, everyone can consume, and users control what gets shared in real-time.
