Kastle

Kastle builds AI voice agents purpose-built for mortgage and loan servicing, automating the repetitive but high-stakes borrower phone interactions that constrain servicers by headcount. Its agents guide borrowers through payment collection across varied methods and schedules, answer escrow and account questions, verify new borrowers during onboarding, engage early-delinquent borrowers with low-friction ways to pay and resolve accounts, and qualify new loan inquiries as an initial filter before a human loan officer is involved. The models are pre-trained to comply with stringent mortgage lending regulations, with audit-ready oversight, and the platform runs 24/7 across call, text, email, and webchat, absorbing call-volume spikes and routing inquiries to the right lending or servicing partner. Positioned as one of the most deployed voice agents in the mortgage industry, Kastle serves FDIC-insured banks and independent mortgage banks, and a partnership with Haven lets servicers deliver the whole experience under the original lender's brand through a single phone number. Vendor and press reported outcomes include call center cost reductions of 80-90% and integration going live in roughly seven days. Founders Rishi Choudhary and Nitish Poddar bring mortgage-technology and AI-systems backgrounds from Redfin and Verkada. Winner of LendingTree's 2024 Innovation Challenge.
