Closed-Loop Performance Engineering

Performance.
End to end.
Verified.

An engineer's hunch. A controlled load test. A sweep that surfaces waste already costing you latency or money. Perfloop quantifies the opportunity, builds the performance case, drafts the reviewable change, and verifies the result in production.

Find. Fix. Prove. Remember.

More software needs to be fast now — not less. Every API, every tool call, every service in the chain. The performance surface is expanding while your team stays the same size. Perfloop runs the loop continuously: quantify the opportunity, map the code, draft the change, verify the result, compound what it learned.

The trigger does not matter — an engineer's hunch, a load test, a proactive sweep, a new service that needs its first baseline. The durable artifact is the performance case underneath.

A serialization path costs 18ms per object. Three services amplify it.
Perfloop found this, mapped the cross-service impact, and opened a PR with two fix paths. Your engineer reviews the case and merges — the investigation is already done.

This analysis took 11 minutes.

Your team would have spent three days investigating — if they got to it at all. Perfloop does the investigation, the math, and the proposed change first. Your engineers review with the context already attached.

It gets sharper over time. Each verified fix teaches the system what works in your stack instead of making the next investigation start from zero.

"We sit on all the telemetry and still miss performance wins because nobody has the time to investigate. Perfloop closes that gap."

Built for teams with real performance pain.

Good Fit
✓
You know performance is costing you somewhere
Sometimes the hotspot is obvious. Sometimes the data has to surface it. Perfloop investigates, proves the fix, and closes the loop.
✓
You have telemetry — or want to
More data means higher-confidence fixes. But if your instrumentation has gaps, Perfloop proposes the cheapest next proof step — a targeted trace, a profiling hook, a benchmark — before it asks your team to change anything.
✓
You have a long tail of performance work
Fixes exist across APIs, jobs, and agent paths — but nobody can spend days proving each one. Perfloop ranks the work first so your engineers review the cases with real upside.

Works with your stack.

Most teams run 2–3 telemetry systems that don't talk to each other. Perfloop reasons across all of them. No consolidation required.

How To Start

Start with a pilot. Join early access.

If you want help on a real performance case now, start with a pilot. If you want the product early, join early access.

Start Here
A pilot on one real performance case, with the evidence and proposed change attached.
First Scope
One repo. One telemetry or profiling source. One bounded environment to start.
Early Access
Join the list for the repo-first product and get in early.
Start Now
Pilot
Open now
For teams that want help on a real case now
Best for teams with real performance pain and one concrete surface to attack first.
First Deliverable
Performance case, proposed change when confidence is high enough, and a before / after review.
How It Works
We start with one bounded case and work directly with your team.
  • ✓  One repo, one telemetry or profiling source, one bounded environment
  • ✓  A real performance case, not a generic audit
  • ✓  Clear scope before work starts
  • Scope and price are agreed up front

Waitlist
For teams that want the product early
Best for teams that want the repo-first product early, without starting with a pilot.
First Product Path
Repo-first analysis with narrower scope and honest proof gaps.
Join If
You want the product early and want a say in onboarding and reports.
  • ✓  Priority access to new repo-first capabilities
  • ✓  Updates on new product capabilities
  • ✓  A chance to shape onboarding and reports
  • Credits are the product usage model
  • ○  Guided onboarding to start
  • ○  Telemetry integrations roll out over time
