Advertising technology platform achieves immediate ROI and discovers major cost optimization opportunities through granular Snowflake cost visibility

Leadership pressure to consolidate warehouses for efficiency eliminated cost visibility, leaving teams unable to answer basic questions about processing costs. Snowflake RSA-provided dashboards were rudimentary and couldn't provide the granular insights needed for optimization decisions.
SELECT provided immediate cost visibility through comprehensive query tagging down to the Airflow task level, enabling precise cost attribution across their consolidated warehouse infrastructure. The platform's intuitive interface eliminated friction from cost analysis, while usage groups enabled aggregate cost monitoring for leadership reporting.
You guys have the best UI experience that I've had of any software. It's like you just read my mind where, like, oh, I wish I could click there. Oh, I can
Diana Koshy, Sr. Director of Data Engineering at Kargo
Kargo has been using Snowflake since its inception, making them one of the platform's earliest adopters. Their architecture centers on processing massive volumes of raw JSON logs from microservices that handle their supply-side platform operations. The platform processes auction data and outcome data across web and CTV advertising channels. As a mature Snowflake user, Kargo initially managed costs through warehouse separation - different microservice logs processed in dedicated warehouses to enable cost breakdowns. However, this approach proved inefficient for resource utilization.
When Diana joined three years ago, leadership was concerned about Snowflake costs and worked with Snowflake RSAs to optimize their setup. The recommendation was warehouse consolidation to improve resource utilization. While consolidation improved efficiency by maximizing usage of already-running warehouses, it eliminated the ability to see cost breakdowns. Teams moved from microservice-level visibility to a single lump sum with no granular insights. The Snowflake RSAs provided basic dashboards, but these were inadequate for the level of analysis needed to optimize their complex, high-volume processing pipelines.
SELECT's Automated Savings feature provided instant value, reducing Kargo's Looker warehousing costs by 30% with zero effort required from the team, and giving Kargo an immediate 5X ROI on SELECT. This immediate cost reduction not only paid for SELECT but demonstrated the platform's value in identifying optimization opportunities that weren't visible through traditional monitoring approaches.
The Kargo team implemented comprehensive query tagging across their pipelines, tagging down to individual Airflow tasks to enable precise cost attribution across their consolidated warehouse infrastructure. This granular tagging immediately revealed their most costly processing pipeline: bid request events, which were costing $500,000 annually - far more than anticipated. This insight enabled a strategic architecture decision to move their most expensive workload from Snowflake to Spark processing, fundamentally changing how they approached their most costly operations.
SELECT's usage groups feature solved a critical reporting challenge by enabling cost aggregation across multiple pipelines and warehouses for high-level business reporting. Usage groups allowed the team to group related workloads and provide accurate aggregate costs to leadership, even when those workloads spanned multiple warehouses and processing pipelines. Leadership could now get instant answers to questions like "how much is this whole targeting thing costing?"
SELECT enabled democratization of cost insights across the data engineering team, allowing individual engineers to track the impact of their optimization efforts independently. This self-service capability transformed how the team approached optimization work, making cost impact visible and measurable for individual contributors rather than requiring centralized analysis. As the team undertook systematic refactoring of their data pipelines, SELECT provided crucial before-and-after visibility that enabled them to measure optimization success.

“SELECT is a team favorite - its cost monitoring and auto savings give us peace of mind that our Snowflake spend is in check. The platform’s detailed insights across SQL queries, dbt, and Looker usage provides a comprehensive view into credit spend that is unmatched by other solutions. SELECT has helped us significantly optimize how we use Snowflake.”

“SELECT's app has become an invaluable resource to our company. It clearly breaks down our costs to allow us to focus on the most important areas of cost. SELECT has repeatedly surfaced inefficient common query patterns, and has helped us spot 200 TiB of unused tables to drop, resulting in continued significant cost savings. SELECT is always adding new features to help their customers better understand and reduce their spending. We can't recommend them highly enough!”

“I love clicking through SELECT to understand how our environment and workloads are evolving. I probably check it every day. It's coffee and SELECT for me every morning.”

“SELECT helps us quickly identify inefficient queries that consume unnecessary Snowflake credits, providing all the information we need in a single application. With the Automated Savings feature, we were able to allocate credits to new compute-intensive data projects.”

“This is the easiest thing we've ever done to save money - 20x ROI. Does this not exist for AWS?”

“SELECT provides our team with complete visibility into all aspects of our Snowflake bill and usage. Our team regularly uses SELECT to monitor costs and get alerted on key changes. The dbt & Looker integrations are also super helpful for identifying performance bottlenecks.”

“SELECT helped us monitor and reduce our overall Snowflake spend by almost 40%. The reporting showed me bottlenecks in minutes that would’ve otherwise taken weeks to dig through metadata and sort out. The 'Automated Savings' savings feature alone is saving us over $10k a month across our accounts, allowing us to bring on new workloads.”

“Before SELECT, we were blind to our Snowflake cost drivers. Minutes after install, we identified a single job that was driving over 20% of our costs. The instant visibility & not having to build & maintain our own monitoring makes a big difference for a lean team like ours.”
