Success runs on performance

We load test digital businesses so they scale with confidence.

Book a callSee how a test works

You're accountable for what you can't verify.

Knowing your product's limits before your customers do is a privilege of the biggest players.

And that's what we're changing.

We find the outage once. Then we trigger it on demand.

The first run finds it. Every run after that reproduces it in your test environment.

As many times as it takes to prove the fix.

What you walk away with

You know what fails first and where to start.

We write the scenario, prepare the test data, and generate the traffic. We need two things from you: what you know about the system, and a test environment we're allowed to send traffic to. Nothing starts without your go-ahead.

Prioritized diagnosis

A list of the places that fail first, starting with the one that hurts most. If your team gets stuck, we sit down with them and help get the fix in.

bottlenecks, in priority order

After every fix

The same test, run again

We send the same traffic after the fix. You see whether it worked and where the system breaks now. If it holds the traffic you planned for, we raise the load until you know how much headroom you really have.

On our end

Your system stays in your hands

Traffic goes from our infrastructure to the test environment you point us to. We install nothing on your systems, and we can stop the test at any time.

Who runs your test

We look after performance where traffic runs into the millions.

We've tested systems in online education, telecom, and live video, where an outage costs money from the first minute. We know where to look for the limit before your traffic gets there.
