CS Disco

CS Disco is a cloud-native legal technology platform designed to help you manage the complexities of modern litigation and investigations. Instead of struggling with slow, legacy systems, you get a high-speed environment where you can ingest massive datasets and search through millions of documents in sub-second time. The platform uses proprietary AI to learn from your document coding, surfacing the most relevant evidence early in the process so you can build stronger case strategies faster.

You can manage the entire litigation lifecycle from a single interface, including data preservation, early case assessment, and production. It eliminates the need for manual data processing and complex database management, allowing your legal team to focus on the facts of the case rather than technical hurdles. Whether you are handling a small internal investigation or a massive multi-district litigation, the software scales automatically to meet your performance needs without requiring additional hardware.

H2O.ai

H2O.ai provides a comprehensive platform to simplify how you build and deploy machine learning models. You can use the open-source library to run distributed machine learning algorithms or choose the AI Cloud to manage the entire lifecycle from data preparation to production monitoring. It helps you solve complex problems like fraud detection, churn prediction, and demand forecasting without needing to write thousands of lines of code manually.

You can take advantage of automated machine learning (AutoML) to quickly find the best models for your datasets. The platform supports both traditional machine learning and the latest generative AI trends, allowing you to build custom large language models. Whether you are a data scientist looking for deep control or a business analyst needing quick insights, you can scale your AI initiatives across your entire organization.
