You are paying for code that isn't pulling its weight.
Most companies are far behind the perf engineering frontier.
Google, NVIDIA, Cloudflare and Linux have deep perf engineering expertise. Most companies struggle to prioritize it, so it shows up as a cloud bill that can be cut by 40–90%.
Agentic coding makes it worse, not better.
We found 118 functions up to 446× slower than necessary in just two AI-written PRs.
The payoff is real money.
A 90% infra cut lifts gross margin, extends runway, and frees capital for hiring and growth. This is the cleanest dollar a CFO will see this year.
An autonomous performance engineer.
Codeflash-agent is an expert performance engineer that runs 24/7, in parallel, with the whole codebase in view. It finds global optimizations a human working file-by-file would miss, and superhuman optimizations humans might fail to discover. Every change is benchmarked faster, proven correct, and delivered as a mergeable PR.
Understands abstractions
Can rewrite 6-step flows as 3-step flows, not just small tweaks.
Verifies correctness
Every change is checked against your existing tests and auto-generated regression tests.
Runs in sandbox
Isolated environment. Your code is never used to train models.
Reviewable PRs
Benchmark numbers and rationale attached to every PR.
How an engagement runs.
Scope
Optimize
Review
Continuous
The bill stays down.
Most optimization wins decay inside a year, because new code arrives faster than anyone can optimize it. Continuous Optimization closes that loop: the same agent that cut your bill stays on, reviewing every new PR and catching regressions where they're introduced. Integrates with Claude Code, Cursor and GitHub, so the code your team ships is optimal on the first commit.
Specialized in ML performance.
We've shipped wins across inference, training, and data processing, through GPU optimization, custom CUDA kernels, and algorithmic rewrites. Including state-of-the-art vision models like RF-DETR and SAM3, and inference frameworks like vLLM and Hugging Face Diffusers. If you run models in production, we've probably optimized your exact stack.
Built for enterprise from day one.
SOC 2 Type 2
Annual audit, continuous controls.
Never trained on your code
Not ours, not third-party. Ever.
Your deployment, your choice
SaaS, your cloud, or on-prem. Same product.
Sandboxed execution
No production access, no exfiltration paths.
" It wasn't just tweaks to existing functions. Codeflash understood the abstractions. If a process had six steps, it would recognize that two or three were unnecessary and replace the flow with a better one. That requires really deep understanding of what the code is actually doing."
