About Kastle

Kastle is a San Francisco-based fintech company building what it calls AI full-time employees for consumer lending. Its agents sit on top of a lender’s existing systems — contact centre, payment processor and loan management systems — rather than replacing the core, and own end-to-end jobs the way a person would: taking the borrower’s call across voice, SMS, email or chat, verifying the borrower, collecting the payment, documenting the file and being measured against the same scorecard as a human agent. Specialist agents cover loan officer assistance, servicing, collections, compliance and loss mitigation, and the company says setup takes days rather than months because agents are mapped to the lender’s existing standard operating procedures.

Compliance is the product’s centre of gravity: the company says its compliance engine is pre-trained on the main US consumer-lending regimes — debt collection, lending disclosure, unfair-practices, mortgage servicing and telemarketing rules — with quality-assurance coverage of interactions and simulation testing before agents go live. Kastle says its platform is in production at 10 of the top 25 US mortgage servicers (company-stated) and has processed more than US$1.8 billion in transactions (company-stated in September 2026 coverage; its careers page later stated more than US$2 billion). In September 2026 it raised a US$24 million Series A to expand engineering, product and go-to-market teams and accelerate deployments with financial institutions.

Products & services

• Servicing and collections agents — borrower contact across voice, SMS, email and chat; payment reminders, collection and past-due recovery.
• Loan officer assistant — origination support including pre-approval letters, appointment booking and warm-lead transfer.
• Compliance agent and QA — compliance engine covering major US lending rules, with interaction QA coverage and automated scorecards (company-stated).
• Agent builder and simulation testing — turns a lender’s procedures into agents in natural language, with scenario testing before production.

Why Kastle is listed: Mortgage servicing is a North American, heavily regulated niche where buyers are identifiable and referenceable — Kastle claims production at 10 of the top 25 US servicers — so a factual profile here serves the exact lenders, servicers and fintech investors evaluating AI workforces for lending.

3 questions to ask this company

1. Total funding was stated as US$26M at the Series A — what was the exact seed amount, given aggregators list figures from US$2.3M to US$2.8M?
2. Agents are measured on the same scorecard as human staff — which scorecard metrics can a lender see per agent, and how are failures escalated?
3. Production at 10 of the top 25 servicers is your headline claim — how many of those run collections or loss mitigation, the highest-risk workflows, today?
