Rogo Raises $75M Series C to Build the Future of Investment Banking and Expand in Europe

Rogo raises $75M Series C to expand its AI‑driven finance platform into Europe and scale its investment‑banking‑focused workflow tools.

Rogo, the New York‑based AI startup that has quietly become a go‑to tool for elite investment banks and private‑equity firms, has just taken a major step toward its long‑term vision. In a $75 million Series C round led by Sequoia Capital, Rogo is using new capital to scale its AI‑driven financial workflow platform and expand into Europe, including opening a London office as its regional hub.

What Rogo Actually Does

At its core, Rogo is not just another chatbot slapped on top of financial data. It’s an enterprise‑grade, secure AI platform purpose‑built for bankers, investors, and financial institutions. The platform helps teams research companies, build market maps, draft deal‑related documents, and prepare presentations in minutes instead of days.

Rogo taps into a wide range of data sources—everything from SEC filings and transcripts to private data rooms and market‑research reports—then surfaces actionable insights with auditable citations. That means a junior analyst can pull together a clean, well‑sourced company profile or competitive analysis in a fraction of the time, while a senior partner can jump into a client meeting with sharper, more grounded talking points.

Series C Funding and What It Means

The $75 million Series C round, led by Sequoia Capital with participation from Henry Kravis, Wells Fargo, and existing backers like Thrive Capital, Khosla Ventures, Tiger Global, and J.P. Morgan, brings Rogo’s total funding to over $165 million. For a fintech‑focused AI startup, that’s a strong signal that major players in finance and venture capital believe AI‑driven enterprise tools for banking and investing are here to stay.

Rogo says the new capital will be used to scale its agentic AI system for financial workflows, deepen integrations with existing enterprise systems, and push adoption across global financial institutions. Instead of just trimming a few hours off grunt work, the company is positioning AI as a way to improve decision‑making, preparation, and analysis at the highest levels of deal‑making.

Founders and the Team Behind Rogo

Rogo was founded in 2021 by Gabriel Stengel and John Willett, both of whom bring deep experience from the intersection of finance and technology. Their background is key to why Rogo doesn’t feel like a generic AI tool bolted on to finance problems. Instead, it’s built by people who have lived the long nights, endless spreadsheets, and last‑minute deck revisions that define investment banking and private‑equity research.

The company pairs that domain expertise with teams of AI researchers and engineers, fine‑tuning models such as GPT‑4‑class systems and OpenAI’s o1 series for financial‑specific tasks. This layered model architecture lets Rogo match different workloads to different models—smaller models for routine queries, more powerful ones for high‑stakes analysis—which helps keep costs under control while still delivering accurate, grounded outputs.

Expanding into Europe

One of the clearest themes from the announcement is expansion into Europe. Rogo is opening its first international office in London, which will act as a regional hub for customers across the continent.

The London office will be led by co‑founder John Willett, who will spend the next year building relationships with European financial institutions and helping firms roll out Rogo’s platform in ways that fit their internal workflows and compliance requirements. For banks and asset managers in Europe—where regulation and data‑handling standards are strict—this on‑the‑ground presence signals Rogo’s commitment to enterprise‑grade security and tailored deployment models, not one‑size‑fits‑all AI.

Generative AI and the Future of Finance

What stands out about Rogo is that it’s not marketing itself as a cost‑cutting toy. The company is positioning its platform as an intelligence layer for Wall Street, meant to augment judgment and prep work, not simply replace junior staff tasks.

Already, thousands of financial professionals across major firms—reportedly including houses like Rothschild, Jefferies, and Lazard—are using Rogo daily to streamline workflows such as meeting prep, diligence, and report generation. For busy bankers and investors, that can mean saving 10+ hours per week on repetitive research and administrative work, freeing them up to focus on higher‑level strategy, client relationships, and deal execution.

Rogo’s Series C story is also a snapshot of how generative AI is moving from experiments to core infrastructure in finance. Institutions that were once skeptical of AI copilots are now investing in secure, compliant, workflow‑aware platforms that plug into their existing systems and data sources.

Platforms like Rogo are showing that the real value of AI in finance may not just be speed or cost savings, but better‑prepared teams, sharper insights, and more confident decision‑making. As the company scales its platform and deepens its presence in Europe and beyond, it’s betting that the next generation of investment banking will be built as much on AI‑driven intelligence as on traditional spreadsheets and leg‑work.
