E25 [DEEP DIVE]: How Metric Trees Are Transforming Businesses with Vijay Subramanian

In this episode, we introduce a new format for the podcast—a deep dive into a technical topic with an engineer-founder who is an expert on the subject. For our first Deep Dive, I sit down with Vijay Subramanian, the visionary behind Trace, to explore the evolution and future of metric layers in business metrics and cross-functional alignment. Vijay demystifies the concept of metrics layers, metric trees and semantic layers, explaining their components, functionality and crucial role in today’s tech-driven environment, while also clarifying the differences between each concept. We discuss how metrics layers drive organizational transformation, standardize processes and are being utilized by tech giants like Uber and Airbnb to optimize data modeling and business operations. Vijay also emphasizes the need for data analysts to adopt an operational mindset and highlights the transformative role of AI in data analysis, particularly generative AI’s potential to revolutionize business data interpretation and storytelling.Highlights:[1:23] - Vijay defines metric layers, metric trees and semantic layers, distinguishing between each and discussing why they’re important[5:21] - We discuss how the world was introduced to the idea of a metrics layer and why it was important[8:15] - We analyze what made the hyper-scalers (Airbnb, Uber, DoorDash) get excited about the idea of a metrics layer at around the same time and Vijay shares where the market stands now in adopting metric layers[13:09] - Vijay digs specifically into metric trees, what they are and where they’re useful and shares more about his decision to build his company, Trace, around the concept of metric trees[17:09] - We discuss build vs. buy and what led to Vijay’s bet that companies were not going to build their own solution internally[21:50] - Vijay expands on how metric trees can bridge the gap between technical teams and business teams within an organization[25:20] - A quick discussion on how the rise of generative AI impacts this space-- Mark your calendars for May 12-14, 2026 and join us for Data Council AI, the technical conference built by engineers for engineers. It's the only event where you'll be able to connect with 2,000+ practitioners for 3 full days of technical deep dives, battle-tested architectures and production insights in San Francisco, the heart of the AI world.
