Know the site holds before you buy the traffic.
We simulate the load your campaign will create, find what gives way first, and tell you what to fix while there is still time to fix it.
We test for companies across industries — aerospace, energy and manufacturing among them.
The campaign works. The site doesn't.
You build the campaign, buy the media, and the clicks arrive. Then the site slows, the form stops posting, and the best day of the quarter turns into a call with your host. A campaign is only ever as strong as the site behind it, and finding that out live costs you trust as well as money. A load test moves the discovery to a Tuesday afternoon, before the spend.
What a load test gives you
Numbers, not hope
You see how the site behaves at each traffic level, so you size servers on evidence.
The bottleneck named
We find where response times give way, and what to change to raise the ceiling.
A cleaner launch
You go live knowing the site takes the volume you bought. Fast sites also rank better.
How the engagement runs
Tell us the launch
The date, the campaign, and the traffic you expect it to send.
We record the journeys
We script the paths that carry your revenue: checkout, forms, search.
We ramp the load
Virtual users up to your target and past it, held for the agreed duration.
You get the fix list
Where it slowed, what broke first, what to change before you launch.
Tests shaped around your traffic, not a template
Peak load looks different in every sector. An ecommerce site takes its hardest hit in a flash sale. A healthcare platform takes it during a registration window. So we load the journeys that carry your money rather than running a generic test and handing you a chart. The work runs across aerospace and defense, manufacturing, print and packaging, and electronics.
What sets the price
Three inputs, one quote, fixed before we start. Change an input and we tell you what it does to the number.
Concurrent virtual users
How many simultaneous visitors we simulate at peak.
Test duration
How long we hold the load once it is up to target.
Scripts recorded
How many user journeys we build, script and run.
How this runs inside GrowthOS
Load testing runs against the same site the system deploys, before campaigns send traffic at it — so launch day is a checklist, not a gamble.
