The Long ViewOneStream: Single Source of Truth
OneStream is a case study on how to build a PCG, using a strategy we call the “Single Source of Truth” (SST).

OneStream is a case study on how to build a PCG—a multiproduct powerhouse where every additional SKU makes every other product better. By providing financial consolidation software that captures "GAAP-blessed financials," they put themselves in the epicenter of data, where they have a competitive advantage in selling additional products, like planning and analytics packages. Moreover, 3rd parties are building on their platform, creating a rich ecosystem. We call this strategy the "Single Source of Truth” (SST).
OneStream is a stellar example of an SST: they applied the theory to bootstrap the company to $100M+ ARR, and today have grown to the tune of over $350M+. What began as a modern consolidation replacement solution, built to be head-over-shoulders better than legacy providers, has since expanded into a multi-product platform serving more than 1K customers with several use cases. We’ll provide a brief history of OneStream and then dig deeper into the key expansion points in the journey from being a Single Source of Truth to a Platform of Compounding Greatness, leveraging the office of the CFO. We’re fortunate to have the opportunity to join the OneStream team on this journey and are excited to have them as one of our portfolio companies. This company rules—and we think you’ll see why we were excited enough about it to commit millions.
Tom Shea, Bob Powers, and Craig Colby were established industry leaders in the corporate performance management (CPM) space well before the idea of “one stream of data” was conceptualized. CPM software helps businesses grapple with hundreds, if not thousands, of disparate data sources by automatically aggregating this data flow into clearly defined KPIs that companies can use to make informed strategic decisions.
