Kastle, an AI platform founded by Indian Americans, has secured $24 million in Series A funding to enhance financial services through automation and efficiency.
Kastle, an applied AI company specializing in financial services, has successfully raised $24 million in a Series A funding round. Founded by Indian American entrepreneurs Rishi Choudhary and Nitish Poddar, the San Francisco-based company aims to transform the lending landscape.
The company has developed KastleOS, an AI agent operating platform tailored for consumer lending. This innovative platform is designed to automate tasks throughout the entire loan lifecycle, enabling lenders to enhance their operational capacity and expand their businesses.
The funding round was led by Insight Partners, with participation from existing investors Y Combinator and Commerce Ventures. Fifth Wall also joined as a new investor, further solidifying Kastle’s financial backing.
As banks and other lending institutions increasingly turn to AI to streamline repetitive tasks and boost productivity, they face significant challenges. Replacing core lending systems can take years and introduce considerable migration and operational risks.
However, Kastle is pioneering a different approach by developing AI agents that operate on top of the existing infrastructure used by financial institutions. These agents are capable of managing high-volume operations, allowing human employees to focus on more complex cases.
“For years, enterprises have effectively been presented with a false choice: accept the limitations of legacy operations or endure a long and risky replacement of the systems at the heart of their business,” said Rishi Choudhary, co-founder and CEO of Kastle. “Kastle creates a third path. We give financial institutions an AI workforce that can operate across the systems they already have, so they can capture the benefits of AI now — not five years from now. We believe this will become the safest and fastest way for the world’s largest institutions to become AI-native.”
The platform will initially concentrate on consumer lending, an area characterized by a high volume of repetitive tasks associated with loan applications and related processes. Kastle reports that its agents have already processed over $1.8 billion in transactions.
In addition to improving productivity, banks require AI systems that can operate reliably while adhering to regulatory and compliance standards and integrating seamlessly with their existing systems.
Rebecca Liu-Doyle, managing director at Insight Partners, expressed enthusiasm for the partnership, stating, “Kastle deploys AI agents that can navigate complexity, pass the bar on regulatory rigor, and get high-stakes work done without waiting for a multiyear transformation. We’re thrilled to partner with the Kastle team as they continue to reshape this category.”
Kastle plans to utilize the new capital to expand its footprint among North American financial institutions, enhance its engineering, product, and go-to-market teams, and accelerate the deployment of its solutions.
According to American Bazaar, this funding marks a significant step forward for Kastle as it seeks to redefine the role of AI in the financial services sector.
