"We were spending $13K a month on AWS. LeanOps cut our cloud costs by 80%, improved performance, and reduced onboarding from days to hours."
The Challenge
Infrastructure complexity often becomes a bottleneck for fast-moving teams. SaaS Unicorn faced significant hurdles in maintaining reliability while scaling their user base from initial thousands to over 10 million active users.
Our Approach
We implemented a robust multi-phase optimization strategy, focusing on high-impact areas that directly improved performance and significantly reduced monthly cloud spend.
