Testlio Appoints Former Zoom and Salesforce Executive Darin Brown as Chief Technology and Product Officer

AUSTIN, TX – MAY 6, 2026 – Testlio, a leading AI-powered crowdsourced testing platform, today announced the appointment of Darin Brown as Chief Technology and Product Officer (CTPO). Brown joins Testlio to lead the company’s global technology strategy and product evolution to meet the growing demand for both rigorous software QA and specialized AI validation.

Leadership Built for Global Scale

Brown brings more than 20 years of experience scaling enterprise SaaS platforms. Most recently, he led product strategy for the Productivity Apps group at Zoom following its acquisition of Docket, a meeting productivity platform he co-founded. Previously, Brown served as CTO of Angie’s List and held VP-level leadership roles at Salesforce, where he built high-performing global technology organizations.

"Testlio has built something genuinely rare: a powerful platform backed by a massive, expert community," said Brown. "The opportunity now is to use AI to empower that community. Whether we’re validating a complex payment gateway or a new LLM interface, our goal is to provide the definitive standard for shipping software with confidence."

The Future of Human-in-the-Loop Testing

Testlio’s approach integrates proprietary AI-powered technology with a vetted global community to provide comprehensive coverage across AI, payments, localization, accessibility, and functional testing. This human-in-the-loop model ensures that software is validated by real people, on real devices, in real-world conditions, nuances that AI alone cannot replicate.

"The industry is at an inflection point where brands need to move fast while ensuring their core product experiences remain flawless," said Summer Weisberg, CEO of Testlio. "Darin has the unique background needed to drive our next phase. He will focus on advancing and scaling our platform, ensuring our customers can navigate the complexities of modern software and AI validation."

As CTPO, Brown will oversee Testlio’s global product and technology organizations, focusing on deepening the synergy between human expertise and machine efficiency. His leadership will be central to shaping how LeoAI Engine™ continues to scale human-in-the-loop validation with the company’s global expert community across AI safety and benchmarking (via the proprietary LeoPulse™ score), global payment and transactional testing, and localization and cultural readiness.
