Kastle

Kastle

Kastle builds AI agents that automate loan operations across the full lending cycle for banks and lenders. Kastle deploys specialized agents — for loan-officer assistance, collections, servicing, loss mitigation, and compliance — that work across voice, SMS, email, and chat and connect to core systems, contact centers, and payment processors. A no-code builder turns a lender's standard operating procedures into working agents, and a compliance engine trained on lending regulations supervises the conversations, so lenders can automate routine borrower interactions with monitoring and QA in place.

Production credibility: Kastle is a live platform at kastle.ai focused on AI agents for lending. The site states it is in production at 10 of the top 25 US servicers, cites a Carrington Mortgage Services partnership across a large servicing portfolio, and reports figures such as 70% lower cost per call and 40% lower handle time. Its compliance engine references rules including FDCPA, TILA, and TCPA. Kastle won LendingTree's 2024 Innovation Challenge and raised a Series A led by Insight Partners. The performance numbers are the vendor's own claims.

Ideal Use Case

Kastle fits banks, mortgage banks, and consumer lenders and servicers that handle high volumes of borrower calls and messages across the loan cycle and need compliance built into every interaction. It is best for lending operations teams that want to automate originations, servicing, and collections with monitoring and QA. It is a weaker fit for businesses outside regulated lending, since Kastle's agents and compliance engine are built specifically for loan operations.

How Kastle differentiates

General voice-AI tools do not understand lending rules. Kastle's angle is loan-cycle agents with a compliance engine trained on regulations like FDCPA and TILA, explainable reasoning, and 100% QA coverage, so a lender can automate borrower conversations across channels while keeping supervision and audit trails in place.
