Experimentation Software Teams for CRO Platforms

A/B tests that never ship waste growth budget — let us build the experimentation software your product team can actually run.

Valletta Software is EU-incorporated in Malta. We build experimentation software and CRO software development solutions — A/B testing engines, heatmaps, session recording, and personalisation — under NDA before kickoff and fully GDPR-compliant.

Experimentation software specialists. EU-based. NDA first.

We know CRO software development and experimentation platform architecture

Experimentation platforms must deliver statistically valid results at speed without degrading page performance. We staff your project with engineers who have built A/B testing platform developer solutions used by high-traffic growth teams.

At Valletta Software, we focus on two things:

Building experimentation software that runs A/B tests, multivariate experiments, and personalisation at scale without introducing latency or data quality issues.

Providing A/B testing platform developers on EU contracts who integrate with your analytics stack and feature flag system from week one.

CRO & Experimentation Engineering

We give you more than just people. Every engineer and analyst comes vetted, domain-matched, and ready to contribute from week one.

Full-stack engineers who build experimentation software modules for experiment creation and variant assignment

Backend developers who architect CRO software development APIs for statistical significance and result reporting

Data engineers who design event pipelines that power heatmaps and session recording in experimentation platforms

ML engineers who build personalisation models and predictive targeting for A/B testing platform developer tools

Frontend performance engineers who minimise experimentation software flicker and page load impact

DevOps engineers who manage feature flag infrastructure and experimentation platform deployments

QA engineers who validate experiment isolation and sample ratio mismatch detection in CRO tools

You stay in control. We handle hiring, contracts, and HR. You direct the work.
