Hi! 👋
We're the team behind Testa Soft.
Some of us started building online stores in high school.
Others were launching softwares before we turned 21.
We've always liked building things that work and grow. That's how we ended up working together.
Over the past years, we helped growing experimentation programs in companies like Bioma, Holo, ColonBroom, Sintra and others. Inside those companies we understood the main objectives and expectations for website experimentation tool.
Now, we're building the tool we always wished we had.
Testa Soft is everything we learned - turned into a platform that helps businesses move faster.

FAQ
We'll schedule a short onboarding call to align on your integration needs.
The first step is adding our lightweight snippet to your site's <head> and integrating to GA4 and any other data platform you are using.
Once the technical setup is complete, we usually recommend running a quick A/A test as a sanity check — just to confirm events are firing correctly and data matches across platforms. After that, you're ready to launch A/B tests with confidence.
No. We don't believe in feature-gating core experimentation capabilities.
You can run unlimited experiments and track unlimited goals across all your projects. The only limit is your monthly session allowance, so you can scale your experimentation program without artificial restrictions.
From simple button changes to complex architectural experiments.
Testa supports:
- Classic A/B tests
- Split URL tests for entirely different pages
- HTML/CSS tests (append, prepend, remove, or modify elements)
You can also run cross-domain tests if your user journey spans multiple sites.
Yes. We believe there's no such thing as "too much data."
Testa integrates directly with GA4, pushing experiment and variant IDs so you can analyze results using the segments you already have. You can also connect Testa to other analytics or data platforms via event listeners.
No. Testa is built to be flicker-free and high-performance.
Our snippet is lightweight and executes early in the browser, ensuring visitors never see the original version before a variant loads — without bloating your site or slowing it down.
We take a privacy-first approach.
We track experiment interactions and conversion events, but we don't store sensitive personal information (PII) on our servers. You own your data; we just provide the engine to help you identify Control & Variation segments in your data stack.
Yes. Agencies can manage multiple client projects from a single workspace under one login.
This makes it easy to scale your CRO services without juggling separate accounts or setups.
We won't shut down your experiments mid-test.
If you exceed your session quota, you'll only be charged for the additional sessions. If you're consistently hitting the limit, we'll proactively reach out to discuss a plan that fits your traffic. Our goal is to keep your tests running — not interrupt momentum.
You won't be routed to a chatbot.
You get direct access to CRO specialists and engineers who have done this numerous times. Whether it's technical troubleshooting or advice on your experiment configuration, we are always available on a shared slack channel.
Test smarter. Get insights that matter.
A testing approach focused on meaningful insights — helping teams make data-driven decisions faster and with clarity.
