Two former junior bankers who quit their jobs because they were tired of grunt work have just raised $160 million to automate it for everyone else. Rogo, the New York-based startup building agentic AI for the financial services industry, announced its Series D round on April 29, valuing the company at $2 billion -- more than double the $750 million valuation it carried just three months earlier.

Kleiner Perkins led the round, joined by a blue-chip roster of investors that includes Sequoia Capital, Thrive Capital, Khosla Ventures, J.P. Morgan Growth Equity Partners, BoxGroup, Mantis VC, Jack Altman, Evantic, and Positive Sum. The raise brings Rogo's total funding to more than $300 million and marks one of the largest venture rounds in the vertical AI-for-finance space this year.

From Spreadsheets to AI Agents

Rogo was founded in 2022 by Gabriel Stengel, a former Lazard analyst, and John Willett, a former JPMorgan Chase banker -- both Princeton computer science graduates who saw firsthand how much of investment banking remained stubbornly manual. What started as an AI-powered research assistant has evolved into a full agentic platform that now serves more than 35,000 professionals across over 250 financial institutions, including Rothschild & Co, Jefferies, Lazard, Moelis, and Nomura.

The company positions itself not merely as a tool vendor but as a long-term AI transformation partner for financial institutions, combining purpose-built financial reasoning models with deep integrations across internal and external data sources to automate research, accelerate workflows, and deliver analyst-grade insights in seconds.

"The world's most sophisticated financial institutions are fundamentally reshaping how they operate using AI, and they're choosing to do it with Rogo," said CEO Gabriel Stengel. "The institutions at the forefront are rapidly moving beyond automating tasks to becoming AI-native firms, with agentic systems that work across the firm and get smarter with every deal."

Meet Felix: The AI Banker That Never Sleeps

The centerpiece of Rogo's product strategy is Felix, its flagship AI agent introduced alongside the funding announcement. Unlike the chatbot-style interfaces that dominated the first wave of AI in finance, Felix is designed to execute complex, multi-step financial processes autonomously. It can screen deals, generate Confidential Information Memorandums (CIMs), conduct buyer outreach, and perform data room diligence -- workflows that traditionally consume hundreds of junior banker hours per engagement.

Financial professionals can interact with Felix by simply sending it an email, and the agent customizes the information it generates based on each user's role and context within the firm. It represents a shift from AI as a question-answering layer to AI as an autonomous workflow engine capable of operating asynchronously across transactions, portfolios, and client relationships.

A Generational Bet on Vertical AI

Mamoon Hamid, Partner at Kleiner Perkins, framed the investment in sweeping terms: "Rogo has built an AI platform that the most demanding institutions in finance trust with their most critical workflows. Their combination of technical depth, proprietary data integrations, and genuine domain expertise is why Rogo is pulling away from the field. When a platform becomes the operating system for an entire industry, the opportunity is generational."

That language -- "operating system" -- is deliberate and revealing. It signals that Kleiner Perkins sees Rogo not as a point solution but as infrastructure, the kind of platform that becomes so embedded in daily workflows that switching costs make it effectively permanent. For Wall Street firms already restructuring their operating models around AI, rethinking staffing pyramids, and deploying autonomous agents, Rogo is positioning itself as the rails on which all of that transformation runs.

What It Means

Rogo's $2 billion valuation is a striking data point for a company that raised just $18.5 million in its Series A in late 2024. The explosive growth trajectory reflects both the genuine demand for AI in financial services and the premium that investors are placing on startups that combine deep domain expertise with agentic capabilities -- rather than simply wrapping a general-purpose large language model in a financial skin.

The round also underscores a broader trend: the most valuable AI companies in 2026 are increasingly vertical specialists, not horizontal platforms. While the foundation model wars continue to rage among the hyperscalers, firms like Rogo are quietly capturing the high-margin, high-trust workflows that require specialized reasoning, regulatory awareness, and institutional-grade security.

With $300 million in the bank, a client list that reads like a who's who of global finance, and an AI agent that can do the work of a first-year analyst in minutes, Rogo is making a clear bet: the future of Wall Street will be built by algorithms, not by bleary-eyed junior bankers pulling all-nighters in midtown Manhattan. For the 35,000 professionals already using the platform, that future has already arrived.
