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, drop latency, and reduce data size.
for teams running APIs, data pipelines, or high-throughput systems
Typical results: 3–5× faster execution | 5× less disk space → fewer servers, lower costs.
We audit your infrastructure for free to find exactly where you are bleeding compute and cash. You only pay if we successfully reduce your costs.
We specialize in optimizing high-throughput APIs, database execution, serverless infrastructure, data pipelines, and AI token consumption.
Business outcomes, not benchmarks.
Same system. Same logic. Just dramatically more efficient.
Specific problems we solve.
Targeted optimization for the most expensive execution bottlenecks.
Database Size & Speed
Shrink database footprint, eliminate ORM over-fetching, and multiply query throughput.
Slow Node.js APIs
Unblock the event loop. Multiply raw throughput without adding more Docker containers.
High AI / LLM Cost
Slash redundant token spend and fix the orchestration overhead crashing your streams.
Serverless Cost Explosion
Cut AWS Lambda GB-second costs by up to 90% by optimizing runtime efficiency.
Email Infrastructure
Clear millions of queued jobs and template rendering without pegging worker CPU.
Vibe-Coded Apps
Survive the scale of AI-generated backends by replacing bloated execution paths.
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."
