Tray.io, an enterprise workflow automation platform that lets users tie in APIs from various apps, raises $50M Series C, source says valuing it at $600M+
Organizations are always looking for new ways to work more efficiently, but too often the problem is that, in a digital-first environment …
Context & Ripple Effects
Seven months after its $37M Series B led by Spark Capital, Tray.io is back with a $50M Series C at a reported $600M-plus valuation — a faster and larger round built on a customer base that already included Lyft, Intercom, IBM, and SAP. The raise lands in a funding wave for enterprise automation: weeks earlier, UiPath pulled in $568M at a $7B valuation (Series D led by Coatue).
The category Tray.io sits in — connecting app APIs into automated workflows — is where the money is converging, and the trajectory is steep: two years later, rival Workato raises $200M at a $5.7B valuation, showing how quickly valuations in this layer compounded.
First-order effects
- Tray.io gets the capital to scale beyond its 200-plus enterprise customers and compete head-on with Workato and UiPath for the same IT and operations budgets.
- Investors are pricing the integration-and-orchestration layer as a distinct market, not a feature of individual SaaS apps — Tray.io's step-up from $37M to $50M rounds within one year is the signal.
Second-order effects
- SaaS vendors whose APIs Tray.io and rivals stitch together face a choice: treat automation platforms as distribution channels or build native automation themselves to keep the customer relationship.
- Workato's much larger subsequent raise forces Tray.io to differentiate on enterprise depth and connector breadth rather than outspending it, while UiPath's process-automation focus pressures both on the IT-side of the budget.
Third-order effects
- If the pattern holds, the workflow-automation platform becomes the de facto control plane across an enterprise's SaaS stack — capturing which apps get used, how they're sequenced, and who owns the business logic between them.
- That consolidation of the orchestration layer sets up the next structural contest over who fronts enterprise workflows, the durable question behind concepts like [[c:workflow-layer-capture|workflow-layer capture]] and the eventual shift toward agents as the interface to automated processes.
The trend: Enterprise software spending is consolidating around the workflow-automation layer that connects app APIs, with each successive round — Tray.io, UiPath, Workato — pricing that middle layer higher than the apps it stitches together.
