Caesar Labs, Inc.

Caesar Labs, Inc. was founded in 2022 by Rahul Sonwalkar following his participation in Y Combinator. The company is headquartered in San Francisco, California, and operates Julius AI, an AI-powered data science platform that enables users to analyze and visualize datasets using natural language prompts without requiring coding skills.

Julius AI processes uploaded datasets and generates Python code, statistical summaries, charts, forecasting models, slide presentations, and dashboards from plain-English instructions. The platform has surpassed 2 million users and generates more than 10 million data visualizations. Harvard Business School incorporated Julius AI into its "Data Science and AI for Leaders" course, and the platform serves both enterprise and consumer use cases.

In July 2025, Caesar Labs raised a $10 million seed round led by Bessemer Venture Partners, with participation from 8VC, Y Combinator, Horizon VC, and AI Grant. Angel investors include Perplexity CEO Aravind Srinivas, Vercel CEO Guillermo Rauch, and Twilio co-founder Jeff Lawson. The company has raised $14.5 million in total funding across three rounds.
