Cut your backend compute costs by up to 90%.
We optimize the execution of your APIs, workers, and serverless systems. Decrease CPU footprint, multiply throughput, and drop latency. Reduce data size.
for teams running APIs, data pipelines, or high-throughput systems
Typical results: 3–5× faster execution | 5x times less disk space → fewer servers, lower costs.
Business outcomes, not benchmarks.
Same system. Same logic. Just dramatically more efficient.
Surgical optimization.
ult.im identifies CPU-heavy bottlenecks and replaces critical execution paths with highly optimized runtime systems.
most APIs are not limited by business logic, but by execution overhead: request parsing, JSON handling, and memory allocations. reducing that layer often yields larger gains than rewriting the system.
Execution model
Analyze workload
We profile your live system to map execution costs.
Identify bottlenecks
Pinpoint the exact functions burning CPU cycles and slowing responses.
Replace critical paths
Drop in highly optimized, low-level execution logic for those specific paths.
Measure gains
Deploy and immediately verify reduced infrastructure load.
"Adrien (ult.im) reduced our page load times by 90% and completely optimized our data pipeline. We handle over 100 million records, and everything is now instant."
