The Spreadsheet Powers Finance. It’s Time for it to Evolve.

The spreadsheet is the workbench of investment banking and investing. It’s the decades‑old tool (nearly half a century, if you start with VisiCalc) that powers the biggest dealmakers on Earth. It also bottlenecks them. Today, we’re changing that. 

We’ve acquired Subset to deliver a supercharged spreadsheet agent in Rogo: one that understands real financial models, connects to your data, and integrates into your workflows.

If you work in Investment Banking, your week is a loop: research → analysis (spreadsheets) → deliverables (slides). Analysts spend countless hours building, updating, and auditing 40-tab models with fragile links, edge-case logic, and stale data.

Most so-called “AI Spreadsheet” tools are just point solutions or demos that break when confronted with real work. They don’t live where you work, and they don’t connect to your data or your outputs. They lack security and integrations to data sources that matter for your workflow. 

Beyond a Point Solution

By bringing Subset into Rogo, we’re delivering the first finance-trained AI agent that operates where you actually work. Rather than a simple point solution, our AI spreadsheet is integrated into a full platform. Subset understands complex formulas, ranges, and the sprawling models that every banker is familiar with, while connecting directly to trusted sources from partners such as Capital IQ, FactSet, PitchBook, LSEG, as well as your firm’s private data.

The agent can build models from scratch, roll them forward, refresh drivers and charts, swap comps, explain and fix errors, and adapt to your templates and style. Analysts can ask, “Why is FCF negative in 2027?” and get a full trace, driver breakdown, and recommended fix. Models update in seconds, not days, and all of it is backed by enterprise-grade controls for security, governance, and auditability.

Subset was founded by Jason Chan and AJ Nandi, and backed by Index Ventures. Jason was previously an Investment Banker at Bank of America and an Investor at Providence Equity Partners; AJ studied Computer Science at the University of Pennsylvania and invested at Insight Partners. Jason and AJ combine finance expertise, engineering rigor, and strong product intuition. They have the exact combination of skills and experiences to tackle this opportunity and are a perfect fit for Rogo.

The Future of Finance

Finance allocates the world’s most precious resource: capital. When workflows are bogged down by manual spreadsheet labor, decision-making across the global economy is bottlenecked.

A spreadsheet agent doesn’t just save analysts time; it accelerates deal cycles, reduces errors, and makes capital markets more efficient. That means the biggest deals in the world can move faster, with fewer mistakes, freeing bankers and investors to focus on what matters most: judgment, ideas, and relationships.

With Subset and Rogo together, the spreadsheet is no longer outdated. It becomes the intelligent workbench that modern finance deserves.
