“Hykell transformed how we manage our AWS costs. By refining our strategy, swapping out a few tools, and automating RI management, they helped us achieve our goal of 30% savings—three times what we were achieving before. Their expertise made the process seamless and aligned perfectly with our broader objectives.”

About the Customer
Scoro is an end-to-end work management software designed for professional services companies that need more than just a project management tool. Based in Europe and serving customers globally, Scoro brings together projects, finances, time tracking, and business intelligence—all in one powerful platform. As a fast-growing SaaS company, Scoro runs a complex AWS footprint to deliver a performant, reliable experience to thousands of users.
Customer Challenge
Scoro’s DevOps and finance teams had a clear target: improve AWS cost efficiency without compromising performance or team velocity. While they had already taken advantage of AWS-native tools like Compute Optimizer and has started using an automation platform to help increase savings, their compute savings had plateaued at around 10%.
They were spending valuable engineering hours manually tracking Reserved Instances (RIs), juggling Savings Plans, and reacting to usage trends instead of proactively managing them. The risk was twofold: growing AWS bills and lost opportunity costs from engineers working on cost ops instead of core product infrastructure.
If the challenge wasn’t addressed, their ability to scale compute usage cost-effectively would become a bottleneck. With planned international growth and new feature rollouts on the horizon, they needed a smarter and more automated approach to AWS cost optimization.
Partner Solution
Enter Hykell.
We started by auditing their existing cost structure, focusing on compute-heavy services like Amazon EC2, Fargate, and Lambda. What stood out immediately: several underutilized RIs, ineffective usage of convertible RIs, inconsistent usage patterns, and an over-reliance on manual decision-making.
Using Hykell’s platform, we brought in automated RI lifecycle management—purchasing, modifying, inflating, deflating and selling RIs based on real-time usage and forecasting. This replaced their spreadsheet-based approach with a fully autonomous strategy. We also migrated some workloads to more flexible instance types and right-sized several services using data from AWS Cost Explorer and CloudWatch metrics.
We integrated directly with AWS APIs and used services like AWS Organizations and AWS Billing & Cost Management to centralize governance and reporting. The Hykell engine constantly monitors usage patterns across accounts and regions, making optimization decisions with zero manual input- everything within the parameters set with the customer.
One underrated win: by eliminating the need for third-party scheduling tools, we simplified their stack and removed hidden costs. Plus, with automated tagging analysis and anomaly detection, Scoro gained more transparency into what workloads were driving the spend.
Results and Benefits
The results were immediate.
Scoro’s compute savings jumped from 10% to over 30% in just under 60 days. That’s a 3x increase—driven purely by smarter automation, strategic adjustments, and better RI handling.
We also helped free up nearly 15 engineering and finance hours per month that were previously dedicated to cost management. That time is now going back into building product features, not monitoring dashboards.
On top of that, their finance team now has predictable monthly spend and better visibility into future commitments—all without having to chase DevOps for data.
