Kastle raises $24 million

Kastle has raised $24 million in Series A funding led by Insight Partners. Existing investors Y Combinator and Commerce Ventures participated, alongside new investor Fifth Wall and a group of founders and financial services executives.

The San Francisco company builds AI agents for consumer lending operations. Its platform works across banks’ and lenders’ existing systems to complete high-volume tasks and update systems of record, while employees handle cases that require judgment.

Kastle says its agents have processed more than $1.8 billion in transactions. It plans to use the funding to expand its engineering, product, and sales teams and increase deployments across North America.
