About Kobalt Labs
Kobalt is the AI-native compliance operating system for financial institutions (FIs). Compliance is critical for FIs to get right, but most of their work still happens manually, in legacy technology or Excel.
Banks, credit unions, and fintechs across the country use Kobalt to run third party due diligence, screen marketing collateral, and stay current with the ever-changing regulatory landscape. Since our Series A, we've grown revenue more than 5x and work with some of the most notable names in financial services, including Chime, Upstart, and Affirm.
The Role

Subscription-based security API for production LLMs
Kobalt Labs provides a high-performance security API for production use of large language models (LLMs). Its service helps businesses integrate AI models (from providers like OpenAI and Anthropic, as well as self-hosted models) with strong data protection and low latency. The API ensures all data interactions are encrypted and never stored or trained on user inputs, which supports privacy and regulatory needs. The product works as a subscription-based API that clients integrate into their applications to secure AI-driven workflows; pricing is tiered to match usage levels and security requirements. Compared to competitors, Kobalt Labs focuses on real-time, low-latency security for AI deployments and emphasizes not storing user data, offering a clear privacy guarantee. The company's goal is to become a trusted security partner for organizations deploying AI by providing reliable, scalable, and privacy-preserving protections for their AI data and model interactions.
