San Francisco startup [Julius](https://zerogtalent.com/ai-companies/julius) raised a $10 million seed round led by Bessemer Venture Partners to build automated AI data analysis tools. The investment featured participation from Y Combinator, Horizon VC, AI Grant, and 8VC, along with angel investors including Perplexity CEO Aravind Srinivas, Vercel CEO Guillermo Rauch, and Twilio co-founder Jeff Lawson, as reported by [TechCrunch](https://techcrunch.com/2025/07/28/ai-data-analyst-startup-julius-nabs-10m-seed-round/).

Founded by CEO [Rahul Sonwalkar](https://zerogtalent.com/people/rahul-sonwalkar) and co-founder [Tanuj Tiwari](https://zerogtalent.com/people/tanuj-tiwari), the 15-person Y Combinator startup operates an AI platform that turns natural language prompts into executable analysis code, data visualizations, and predictive modeling.

## Automating Data Science with Code Execution

Julius functions as a chat-based data scientist. Users upload spreadsheets, CSV files, PDFs, or database connections and query their data using natural language. Rather than relying solely on language generation, the system writes and executes underlying Python code to construct charts, run statistical tests, and handle complex file operations.

According to [Pulse 2.0](https://pulse2.com/julius-ai-10-million-to-democratize-data-analysis/), the platform has accumulated more than 2 million registered users who have generated over 10 million visualizations. Harvard Business School adopted the tool for its required course "Data Science and AI for Leaders," as covered by [TechCrunch](https://techcrunch.com/2025/05/15/fake-fired-twitter-worker-rahul-ligma-is-a-real-engineer-with-an-ai-data-startup-used-by-harvard/).

In an interview on [EO](https://www.youtube.com/watch?v=Djeykrg3WkM), [Rahul Sonwalkar](https://zerogtalent.com/people/rahul-sonwalkar) outlined the scale of the company's code execution engine: "Every day, Julius writes over four million lines of analysis code. Four million lines of code is more than an army of data scientists can write every day."

## Engineering and Research Priorities

Before founding Julius, [Rahul Sonwalkar](https://zerogtalent.com/people/rahul-sonwalkar) worked as a software engineer at Uber on the rider pricing team and at Facebook on the misinformation team. Speaking on [Solo Founders](https://www.youtube.com/watch?v=0GdQAZ9Dlr8), Sonwalkar discussed team composition and early equity allocation: "If a candidate is willing to take less cash or more equity, it's a big green flag. It's like, okay, this person wants more skin in the game."

To support multi-step reasoning and automated code generation, the company is scaling its infrastructure and product engineering teams. 

Infrastructure compute relies on containerized sandboxes across cloud environments. The company is hiring a [Software Engineer - Infrastructure (Mid - Senior)](https://zerogtalent.com/ai-jobs/julius/software-engineer-infrastructure-mid-senior-93231) to own reliability, performance, and security for multi-tenant compute environments. The role involves orchestrating over 500,000 containers per month in AWS and GCP to support automated coding agents.

On the product side, Julius is filling roles across multiple seniority levels. The team is hiring a [Software Engineer - Product (New Grad)](https://zerogtalent.com/ai-jobs/julius/software-engineer-product-new-grad-93234) to build user interfaces for tool use, multi-step reasoning, and code execution. Concurrently, a [Software Engineer - Product (Mid to Senior)](https://zerogtalent.com/ai-jobs/julius/software-engineer-product-mid-to-senior-93233) will scale features that handle complex file management and code generation.

Julius is also building out a dedicated research initiative, Julius Research, to stress-test financial reasoning capabilities in large language models. The company is hiring an [AI Finance Researcher (MBA Student)](https://zerogtalent.com/ai-jobs/julius/ai-finance-researcher-mba-student-119276) to design financial challenges, such as discounted cash flow (DCF) valuations and leveraged buyouts (LBOs), to expose weaknesses in frontier AI systems. Similarly, an [Investment Banking - AI Research (MBA Intern)](https://zerogtalent.com/ai-jobs/julius/investment-banking-ai-research-mba-intern-119277) will create modeling scenarios to establish new performance benchmarks for financial analytics.

To manage public messaging and community education across operations and finance channels, Julius is hiring a [Growth Marketing Manager](https://zerogtalent.com/ai-jobs/julius/growth-marketing-manager-76881). The position owns external content strategy, balancing brand storytelling with search engine performance across social, email, and community channels.
