The open banking ecosystem represents a fundamental shift in how financial data flows between institutions, businesses, and consumers. Instead of siloed banking systems, open banking creates a connected financial data layer that enables innovation across lending, payments, personal finance, and embedded finance. This infrastructure layer is critical because it:
Within this ecosystem, platforms like Landbase help B2B companies target these rapidly growing open banking companies through natural-language audience discovery. Rather than manually researching which open banking companies raised funding or expanded into new markets, GTM teams can use agentic AI to find prospects based on real-time signals.
This list highlights platforms that demonstrate exceptional growth, market reach, and strategic importance in the open banking ecosystem:
The open banking companies on this list represent ideal prospects for B2B SaaS vendors, particularly those offering infrastructure, compliance, security, or developer tools. These companies share common characteristics that make them attractive targets:
This is where platforms like Landbase's VibeGTM interface become essential. Instead of manually identifying which open banking companies fit your ideal customer profile, you can use natural-language prompts like: "Open banking fintech companies that raised Series B+ funding in the last 12 months with engineering teams of 100+." Landbase's GTM-2 Omni model then interprets this query and returns AI-qualified audiences ready for immediate activation.
An Open Banking fintech provides the infrastructure layer that enables secure, consent-based sharing of financial data between banks, third-party providers, and consumers. These companies are growing rapidly due to regulatory tailwinds like PSD2 in Europe and Section 1033 rulemaking in the US, combined with consumer demand for better financial experiences. The market, valued at $35.30 billion in 2023, is projected to grow to $190.94 billion by 2032, driven by increasing adoption of account-to-account payments and data-driven financial services. Open banking API calls alone are projected to surge from 137 billion in 2024 to 722 billion by 2028—a 427% increase.
Open Banking transforms traditional banks from closed systems to open platforms that can generate new revenue streams through API monetization. Rather than viewing fintech companies as competitors, many banks are partnering with open banking platforms to enhance their offerings. For example, JPMorgan Chase strengthened its decades-long partnership with Yodlee, while HSBC, Santander, and BNP Paribas use Token.io for their payment infrastructure. This shift enables banks to focus on their core competencies while leveraging specialized fintech infrastructure for innovation. Traditional banks also benefit from reduced fraud through bank-grade authentication and real-time payment verification.
Open Banking fintechs attract significant venture capital investment and strategic acquisitions from major payment networks. Recent examples include Plaid's $425M Series D in April 2021 at a $13.4 billion valuation and Stripe's $6.5B Series I in March 2023. Major payment networks like Visa and Mastercard have made strategic acquisitions, with Visa purchasing Tink for $2.2 billion and Mastercard acquiring both Yodlee and Finicity. This funding reflects investor confidence in the long-term strategic importance of open banking infrastructure as the market grows from $35.30 billion in 2023 toward $190.94 billion by 2032.
B2B companies can effectively target Open Banking fintech companies by leveraging AI-powered audience discovery platforms that combine natural-language targeting with real-time signals. Instead of manually researching which companies fit your ideal customer profile, you can use prompts like "Open banking companies with 100+ employees that use AWS and raised funding in the last 18 months." Platforms like Landbase provide access to 300M+ contacts and 24M+ companies with 1,500+ unique signals, enabling precise targeting based on funding rounds, hiring activity, tech stack changes, and other growth indicators.
Tool and strategies modern teams need to help their companies grow.
