Optimum Partners Launches TheTester on Mustang, Its Sovereign AI Platform for Application & Service Delivery
The autonomous QA platform now runs on a private institutional knowledge foundation, testing software against original business intent rather than generic assumptions — with no company data sent to public AI models.
Optimum Partners has launched TheTester as the first native workload on Mustang, its sovereign AI platform for application and service delivery. The announcement marks a significant step in the company’s broader strategy to build a suite of AI applications that run on a shared foundation of organizational knowledge, rather than on generic models trained on public data.
TheTester is an autonomous quality assurance system that manages the full testing lifecycle — from reading business requirements and generating test strategies, to writing and executing test scripts, to producing detailed bug reports with video evidence. Since its initial release last year, it has been used by engineering teams to replace manual QA processes and eliminate the ongoing maintenance burden of traditional test automation. Running on Mustang, it now operates with access to an organization’s complete institutional context: product documentation, codebase history, architectural decisions, and engineering specifications, all stored within the company’s own private environment. The result is a material reduction in QA overhead — teams report fewer regression cycles, faster sign-off, and the elimination of the constant script maintenance that consumes QA engineering capacity. Because TheTester syncs continuously with the repository and project management tools, test coverage adapts automatically as the product evolves, without manual intervention each sprint.
The practical consequence is a shift in what automated testing can actually verify. Most QA tools check whether code executes without errors. With access to the original business requirements and product decisions stored in Mustang, TheTester can verify whether the software does what the business intended when it was designed — a distinction that matters significantly in production-grade enterprise environments where requirements drift and context gets lost across teams and sprints.
Mustang runs entirely within a customer’s own Virtual Private Cloud or on-premises infrastructure. No organizational data — codebases, product documentation, test results, or internal specifications — is sent to external systems, exposed to third-party AI models, or used for any form of model training. Intellectual property stays inside the enterprise boundary by architecture, not by policy. For organizations in regulated sectors, or those operating in industries where proprietary technology is a core competitive asset, this removes a fundamental barrier that has prevented widespread AI adoption in core development and delivery workflows.
“I’ve sat in enough client meetings to know that the AI anxiety isn’t about capability anymore, it’s about trust. Who owns the data, who sees it, and what happens to it. Mustang was built to answer all three. TheTester is just the first thing we’ve put on top of it,” said Joe Sticca, CEO Americas at Optimum Partners.
TheTester connects to the broader Mustang suite through Grip, the platform’s natural language interface, and integrates natively with the tools engineering teams already use: Jira, Linear, and Asana for project management; GitHub, GitLab, and Bitbucket for version control and CI/CD pipelines; Figma for design and requirements input; Playwright, Selenium, and Cypress for test framework compatibility; and Slack and Microsoft Teams for real-time notifications and failure alerts.
