Company Description

Zest AI is a financial technology company that develops artificial intelligence software for the lending industry. It provides solutions to banks, credit unions, and other lenders for use in marketing, underwriting, fraud detection, and overall lending intelligence. The company's machine learning software is used to assess borrower risk and automate credit decisions, with its platform managing over $5.6 trillion in assets across more than 600 active models. Founded in 2009 and formerly known as ZestFinance, the company has focused on using AI to make lending more efficient and accessible. It holds over 50 patents in areas including automation, performance, and model explainability.

Looking forward, Zest AI plans to continue advancing its technology with an emphasis on real-time risk detection and supporting community banks in their adoption of AI. Recent announcements underscore the company's activity in the market; in January 2025, Zest AI raised $200 million in a Series G funding round. Company executives have also contributed to industry discussions, with its CEO publishing predictions on the future of AI in banking and its CTO speaking on the impact of alternative data for applicants with limited credit histories. These activities align with industry reports cited by the company, such as a Celent survey indicating that 80% of lenders are increasing their IT spending for consumer loan origination.

Frequently Asked Questions

Is Anduril worth joining?

Joining Anduril as an employee is another way to acquire equity, typically through stock options included in compensation packages.

Is Zest AI worth joining?

Deciding to join a startup like Zest AI depends on your personal career goals, risk tolerance, and belief in the company's mission. A key part of your compensation is equity, and tools like Prospect can help you analyze its potential value to make a more informed decision.

What should I do with my Zest AI stock?

Managing your Zest AI stock effectively requires a personalized strategy that considers your financial goals, tax liabilities, and the company's outlook. Platforms like Prospect provide customized strategies for exercising options and planning for liquidity to help maximize your post-tax equity value.

Can you sell Zest AI stock?

As Zest AI is a private company, you can generally only sell stock during specific liquidity events, such as tender offers or on secondary markets. Prospect offers tender offer tools that help you determine how much to sell and which shares are the most tax-optimal.

How can I find the value of my Zest AI stock?

The value of private stock is formally determined by a 409A valuation, but you can also track its price on secondary markets for a current estimate. To help you understand its potential, Prospect provides predictive models and secondary market price tracking to forecast your equity's future value.

What is Zest AI's equity worth?

The precise worth of Zest AI's equity is not public information and changes based on factors like company performance and new funding rounds. You can use a platform like Prospect to model different scenarios and project the potential future value of your personal holdings.

What is Zest AI's stock ticker symbol?

Zest AI does not have a stock ticker symbol because it is a private company. Ticker symbols are only assigned to companies once they begin trading publicly on a stock exchange.

Can I buy or sell Zest AI stock?

Since Zest AI is a private company, opportunities to buy or sell its stock are limited to specific events like tender offers or secondary market transactions. For employees holding equity, Prospect provides tools to optimize selling decisions during these liquidity windows, but does not facilitate buying stock.

What is the criteria to buy or invest in Zest AI stock?

Investing in a private company like Zest AI is typically restricted to accredited investors who participate in organized funding rounds or approved secondary sales. Prospect's platform is designed for employees who have already been granted equity to help them manage their holdings, not for outside investors looking to buy in.
