About
Zest AI is an AI-powered lending intelligence platform founded in 2009 and headquartered in Los Angeles. The company was founded by former Google engineers and data scientists who saw that traditional credit underwriting — relying on thin FICO score inputs and rule-based scorecards developed in a pre-big-data era — was systematically excluding creditworthy borrowers and leaving billions in loan volume on the table for lenders. Zest AI's mission is to make lending fairer and more profitable simultaneously, by applying machine learning to the full spectrum of available credit data.\n\nThe platform provides AI-driven credit underwriting models that lenders deploy to augment or replace traditional scorecards at the point of loan decisioning. Zest's models ingest hundreds of variables that conventional scorecards ignore, producing more accurate risk predictions that allow lenders to approve more borrowers at the same loss rates — or achieve lower loss rates on the same approval volumes. The company has developed more than 650 proprietary models and holds 50 patents in AI credit underwriting. Zest integrates with major loan origination systems and serves nearly 300 lenders including credit unions, community banks, and consumer finance companies across auto, personal, and small business lending.\n\nZest AI has raised approximately $554 million in total funding, including $200 million from Insight Partners, reflecting the scale of the addressable opportunity in AI-enabled credit decisioning. The company's long operating history since 2009, its proprietary model library, and its documented evidence of bias reduction in lending outcomes position it as the most established AI underwriting platform in the market, with a meaningful head start over newer entrants attempting to commoditize the category.

About
Dext is a London-based bookkeeping automation platform, formerly known as Receipt Bank, that provides receipt capture, expense management, and document processing tools for accountants, bookkeepers, and their small business clients. Founded in 2010, the company rebranded to Dext in 2021 to reflect its expanded product scope beyond pure receipt scanning. Dext has raised $80M in funding and serves hundreds of thousands of accounting professionals and small businesses across the United Kingdom, North America, Australia, and Europe. The platform's core functionality allows users to capture photos of receipts and invoices via mobile app or email, after which Dext's OCR and AI technology extracts key data—supplier, amount, date, tax, and category—and publishes the record to the connected accounting system without manual data entry.\n\nDext has evolved from a receipt capture tool into a broader accounting automation platform with the addition of Dext Commerce for e-commerce transaction management and Dext Prepare for supplier document management. The company positions its product suite as a pre-accounting layer that standardizes and enriches document data before it enters the accounting system, reducing the manual cleanup work that accountants perform on transactions imported from lower-quality data sources. Dext's accountant-centric distribution model—where accounting firms adopt the platform for their client portfolio—mirrors the partner model used by competitors like Botkeeper and Hubdoc.\n\nDext's integration ecosystem covers QuickBooks Online, Xero, Sage, and dozens of other accounting platforms, making it compatible with virtually any accounting firm's technology stack. The company acquired Greenback in 2022, adding transaction fetching capabilities for bank and e-commerce accounts to its document processing platform. Dext competes with Hubdoc (owned by Xero), AutoEntry, and Lightyear in the document processing and bookkeeping automation market, differentiating on the breadth of its extraction accuracy, its multi-product suite, and its established global accountant distribution network.
