Plaid, a financial technology company that enables consumers to securely connect their financial accounts with apps and services, and Sierra, an AI agent platform for customer service, have partnered to help AI agents move beyond one-off conversations and support longer-running financial workflows.
The partnership enables customers to securely connect their bank accounts with Plaid directly within Sierra’s agent. This allows customers to make payments or verify their finances without leaving the conversation, while giving the agent access to the financial information required to support more complex tasks.
The integration builds on Sierra’s Horizon platform, which enables agents to proactively engage with customers over days, weeks or months. Sierra said many financial outcomes, including refinancing a loan, collecting an overdue payment or settling an insurance claim, require agents to orchestrate workflows over time rather than resolve issues within a single interaction.
Plaid and Sierra highlighted loan applications as one example of how AI agents can support longer-running financial processes. If a borrower falls short of qualifying based on their credit score, an AI agent can request permission to access their bank account through Plaid Link, assess income and spending patterns, and continue progressing the application.
The companies said the opportunity extends beyond lending, with AI agents able to support workflows such as insurance claims and fraud resolution. In these scenarios, the agent can determine the next step, request permission to access the required information and continue working towards the desired outcome.
The integration has been designed around security, consumer control and human oversight, with accuracy and compliance positioned as core principles. Every interaction begins with explicit consumer permission through Plaid, while Sierra provides safeguards that monitor AI responses, check for compliance and enable human intervention when needed.
Plaid and Sierra said the partnership is a proof point for the wider shift towards “intelligent finance”, where AI agents move beyond answering individual questions to delivering business outcomes.
