Rogo Technologies, Inc., the leading AI platform for investment banks, today announced the acquisition of Subset, an AI spreadsheet company backed by Index Ventures. The acquisition accelerates Rogo’s mission to modernize the core workflow of investment bankers and investors by delivering an AI‑native spreadsheet experience that automates modeling tasks, explains and fixes models, and connects analysis to downstream deliverables.

Founded by Jason Chan and AJ Nandi, Subset created an AI spreadsheet engine that lets users upload, build, and export fully usable financial models with AI assistance. The founders bring rare finance + AI + product DNA: before starting Subset, Jason worked in investment banking at Bank of America and private equity at Providence Strategic Growth, and AJ studied computer science at the University of Pennsylvania and invested at Insight Partners.

"Spreadsheets are a cornerstone of the finance industry but established tools haven’t kept up with modern technology," said Gabe Stengel, co-founder and CEO of Rogo. "With Subset, we’re pairing the right technology and founders with Rogo’s models and platform to make the daily work of bankers and investors dramatically faster and more reliable.”

By joining Rogo, Subset’s technology becomes part of a connected workflow suite that maps to how bankers and investors actually work. Rogo’s proprietary model and dataset make AI spreadsheets more accurate, traceable, and usable, while the platform’s distribution ensures the agent lands where it matters: inside the entire workflow, connected to the right data and outputs, and not as a point solution.

“We started Subset to make spreadsheet work exponentially more powerful for finance,” said Jason Chan and AJ Nandi, Co‑Founders of Subset. “With Rogo’s model, dataset, and workflow suite, we can deliver that vision at real scale: bringing an AI‑native spreadsheet experience to the world’s top dealmakers and investors.”

Rogo’s Finance Spreadsheet Agent is designed to:

• Automate modeling tasks (model builds from source docs, roll‑forwards, scenario/sensitivity work, audit and error detection)
• Explain and fix any cell or formula with full traceability
• Connect to your data, including providers such as S&P Capital IQ, FactSet, PitchBook, and Refinitiv, as well as private data sources, via secure connectors
• Hand off to deliverables by turning analysis into polished slides and memos
