Paywhere Launches Programmable AI Banking Storefront to Bridge the Gap Between Banks and AI Tools

Paywhere has launched a programmable banking platform designed to bridge the gap between traditional financial institutions and the AI-driven environments where customers now operate. By enabling banks and credit unions to integrate with AI assistants like ChatGPT and Claude, the platform offers a secure way for institutions to retain relationships and deposits currently being lost to neobanks.

What was announced

Paywhere has announced the commercial availability of its programmable banking platform, a solution that allows financial institutions to embed their services directly into AI assistants, applications, and agents. The platform is designed to serve both retail and business banking customers who are increasingly using tools like ChatGPT, Claude, and Microsoft Copilot as their primary operating systems for work and financial management. By providing a financial-grade connective layer, Paywhere enables banks to maintain their branding, account structures, entitlements, and security controls while allowing the customer to interact with their finances through the AI platform of their choice.

The launch addresses a critical shift in the financial landscape. According to research from Cornerstone Advisors, more than $3 trillion has moved out of traditional banks and credit unions into fintechs, neobanks, and digital investment platforms over the past five years. Despite this migration, adoption of AI within traditional institutions remains low; only 7% of banks and 17% of credit unions have deployed AI in any form to date. Paywhere’s platform is designed to work alongside existing core, digital, and bank operating systems without requiring an in-house engineering team to build custom AI models.

A primary focus of the platform is the small business (SMB) sector, which includes 36.2 million businesses in the U.S., accounting for 99.9% of all domestic enterprises. Paywhere aims to solve the "portal fatigue" experienced by SMB owners who often find retail products too simple and commercial products too complex. The platform was demonstrated live at FinovateFall in New York on September 10, 2024, showing how customers can manage banking tasks through an AI assistant while institutional permissions remain intact. This follows the rapid growth of AI tools in the sector, such as Anthropic’s Claude for Small Business, which launched in May 2026 and reached over 900,000 installations by September 17.

"For years, banks and credit unions have watched fintechs win relationships they spent decades building, and the deposits have followed those relationships out the door. AI can accelerate that or reverse it. Customers are moving their financial lives into AI either way. AI will be the new interface of banking and the institutions that meet them there, on their own terms and under their own controls, have a real chance to own the relationship again and stay relevant in the age of AI."

The companies involved

Paywhere is a fintech firm led by founder and CEO Girish Mutreja and co-founder and Chief Strategy Officer Brett Vasconcellos. The company specializes in programmable banking, a model that treats financial services as code-accessible functions rather than siloed portal experiences. This approach is intended to help traditional institutions compete with the agility of digital-first neobanks. The market data supporting this launch is provided by Cornerstone Advisors, a management consulting and research firm that focuses on strategic guidance for the financial services industry. Cornerstone has been a frequent source of analysis in the fintech sector, particularly regarding deposit migration and digital transformation trends.

The platform also integrates with the ecosystem established by Anthropic, an AI safety and research company. Anthropic is the creator of the Claude AI model, which has seen significant adoption in the enterprise and small business sectors. As AI agents become the primary interface for professional workflows, the demand for secure, financial-grade connectivity has grown, positioning companies like Anthropic as critical infrastructure partners for the next generation of banking interfaces.

What FF News has reported before

FF News has extensively covered the intersection of AI agents and financial services. We recently reported on how Anthropic Launches Claude for Financial Advisors to Automate Wealth Management Workflows, a development that mirrors Paywhere’s focus on professional AI environments. The scale of this transition is further highlighted by data showing that Anthropic Dominates UK SME AI Spending as Adoption Surges 1,000% Since 2023. Beyond general assistants, the industry is moving toward specialized agentic commerce, as seen when Mastercard Launches Agent Connect to Power the Future of AI-Powered Shopping. Furthermore, the operational impact of these technologies was demonstrated when LoanPro and AllCloud Launch Claude-Powered AI to Slash Loan Servicing Call Times by 15%, illustrating the efficiency gains available to institutions that adopt programmable interfaces.

What this means

This announcement signals a move toward "headless banking," where the bank provides the balance sheet and compliance, but the user interface is owned by third-party AI platforms. By accepting that customers prefer to work within ChatGPT or Claude rather than a proprietary bank portal, Paywhere is forcing a reality check on the industry. This shift puts significant pressure on traditional core banking providers; if they cannot provide the open APIs required for this level of connectivity, they risk becoming obsolete as deposit-holding utilities with no direct customer relationship. The primary challenge for the sector will be maintaining security and regulatory compliance when the primary interaction layer is a large language model prone to hallucinations.
