Gabriel Stengel is the Chief Executive Officer and co-founder of Rogo, a New York-based artificial intelligence software company focused on transforming how financial professionals work. Alongside his partners Tumas Rackaitis and John Willett, Stengel has guided Rogo from its founding in 2022 into a fast-growing enterprise technology platform used by investment banks, hedge funds, and asset managers in the United States and beyond.
Background of Gabriel Stengel
Gabriel “Gabe” Stengel grew up with a strong interest in both technology and finance. He studied computer science at Princeton University and later began his career on Wall Street as an investment banker with Lazard. There, Stengel gained deep exposure to the labor-intensive processes of financial analysis and modeling, an experience that inspired his vision for Rogo.
About Rogo
Rogo is a generative artificial intelligence platform built for financial professionals to help them work smarter and faster. The company’s tools automate time-consuming tasks such as gathering data, generating financial research, preparing presentations, and drafting analytical documents that would normally take hours if done manually. The platform uses advanced AI models to offer accurate, auditable financial insights and integrates directly with typical investment banking workflows.
Founded in New York in 2022, Rogo aims to make high-level financial work more efficient, helping firms reduce repetitive manual labor so teams can focus on strategic decision-making, client interactions, and high-impact analysis.
Founders and Their Roles
Rogo was co-founded by three leaders with complementary strengths:
Gabriel Stengel serves as Chief Executive Officer (CEO). In this role, he leads the company’s overall strategy, product vision, and growth efforts. Stengel’s finance background helps ensure the technology solves real problems that financial professionals face every day.
Tumas Rackaitis is Chief Technology Officer (CTO). He oversees the technical architecture and innovation behind Rogo’s AI platform, ensuring it meets the demanding standards of enterprise-grade finance software. Rackaitis brings deep expertise in AI and engineering to the team.
John Willett holds the role of Chief Operating Officer (COO). He focuses on day-to-day operations, scaling the business, and aligning internal teams to support customers and partners. Willett’s experience complements Stengel’s product vision by managing execution and operational efficiency.
Together, this founding team combines experience from investment banking, software engineering, and business operations to build a platform that meets the unique needs of finance professionals.
Leadership and Style
Stengel leads Rogo with a practical and user-centered approach. His leadership emphasizes solving real workload problems faced by analysts and bankers rather than pursuing abstract technological ideas. He encourages his team to listen closely to customer feedback, iterate quickly, and build tools that make professionals’ work more efficient, accurate, and satisfying.
This people-focused leadership has helped Rogo foster a culture of disciplined innovation. Stengel and his co-founders stress clear communication, mutual respect, and product excellence, qualities that have helped the startup attract top engineering talent and enterprise customers.
Achievements and Impact
In just a few years since its founding, Rogo has secured significant venture funding, growing from seed capital to major institutional backing. The company has raised tens of millions of dollars from world-class investors and expanded its customer base to include top financial firms that rely on its AI platform to reduce manual workloads and accelerate high-value work.
The platform is now used by dozens of financial institutions, supporting thousands of professionals who benefit from automated insights and faster research workflows. This enhances the productivity of U.S. financial teams, helping them respond more quickly to market changes and allocate human expertise to strategic priorities.
Contribution to Efficiency in the U.S. Financial Sector
While Rogo is not a government program or public welfare initiative, its technology has a practical impact on how financial professionals in the United States work. By automating repetitive tasks and delivering accurate information faster, Rogo enables teams at investment banks and other financial firms to operate more efficiently, reduce turnaround times, and focus on higher-order judgment. This contributes to the competitiveness of U.S. financial institutions in global markets.
Personal Approach and Future Plans
Stengel’s personal philosophy emphasizes augmenting human expertise with technology. He often speaks about AI tools as partners that complement, not replace, human judgment, allowing professionals to make better decisions with less strain.
Looking ahead, the Rogo leadership aims to expand the company’s platform capabilities, support broader use cases in finance, and grow internationally. Continuous investment in research and development, deeper integration with enterprise systems, and partnerships with global financial institutions are key parts of their roadmap.
Gabriel Stengel, together with co-founders Tumas Rackaitis and John Willett, has built Rogo into a dynamic AI company that serves the evolving needs of financial professionals. With an emphasis on practical impact, strong leadership, and deep domain expertise, Stengel and his team are shaping how modern finance works, automating routine work and freeing human professionals to tackle the most meaningful challenges in their industry.
