Addy AI

Kastle is building the AI workforce for financial services, starting with consumer lending: AI agents that run inside lenders' existing systems to automate intake, collections, compliance, servicing and loss mitigation. Its agents have processed more than $1.8 billion in transactions.

Vesta (Vesta Innovations, Inc.), founded in November 2020 in San Francisco by former Blend early team members Mike Yu and Devon Yang, builds an AI-native mortgage loan origination system (LOS) combining a system of record, a workflow engine and open APIs, with AI agents handling document review, underwriting decisions and workflow tracking. Customers include Pennymac, New American Funding, Upstart and nbkc Bank.

Finster AI, founded in 2023 in London, UK, provides AI-driven research and document process automation software for banks and asset management firms.

Elio Mortgage, founded in 2026 and based in New York, is an AI-native mortgage company that runs its own licensed brokerage (it acquired Florida-based Hightide Mortgage in January 2026) rather than selling software to lenders. AI agents handle pre-qualification, document processing, income calculation, conditions resolution and borrower communication. It lends direct to borrowers and through embedded partnerships with financial advisors, real estate agents, home builders and single-family rental owners, with about 40 loan officers licensed in 22 states.

Zango, founded in 2024 in London, UK, uses AI agents trained on regulatory data to automate compliance monitoring and audit preparation for banks.

Rulebase, founded in 2024 in London, UK, uses AI agents to automate compliance, dispute resolution, and back-office processes for financial institutions.
