Chief Executive Officer — Witbe
CEO & Director of R&D • Witbe • Since 2019
"You can't fix what you can't see."
Profile
Every time a Comcast subscriber watches Peacock without a buffer, somewhere in a rack is a Witbe robot that already caught the problem before they did.
Mathieu Planche runs Witbe from San Francisco, but the company was born in Nanterre, France in 2000 - when streaming video was still a dial-up dream. He took the CEO chair in April 2019, inheriting a company that already had 19 years of muscle memory in video quality testing, and has spent the years since turning it into an AI-first monitoring empire.
The path to CEO was the kind that makes a resume interesting: consultant, UI designer, Americas Operations Manager, Chief Experience Officer, Chief Product Officer. He held every seat at the table before sitting at the head of it. That progression is why Planche is unusual among tech CEOs - he doesn't just understand the product, he designed parts of it.
Witbe's philosophy is blunt: real problems happen on real devices, not in simulators. So the company built an army of actual physical televisions, set-top boxes, smartphones, and tablets - 20,000 of them in 120+ countries - that silently run tests around the clock, the way an actual viewer would. If the ad doesn't load, if the stream stutters at 4K, if the voice remote mis-routes a command: Witbe sees it first.
Under Planche, the company extended that premise into the AI era with Witbe Agentic AI - not chatbots, but autonomous agents that design test scenarios, execute them across devices, and explain what failed and why. The industry's first agent-native QA platform for video. When that launched in late 2024, Witbe had already won three straight NAB Show awards. It has since won a fourth.

Career Arc
Planche didn't job-hop his way to the top. He stayed at Witbe - moving through technical, operational, and executive roles - for over a decade before becoming CEO. Each transition was a ratchet, not a reset.
The Company
Founded in 2000 by Jean-Michel Planche and Marie-Veronique Lacaze, Witbe has been monitoring video quality for longer than YouTube has existed. The company is listed on Euronext Growth under ticker ALTWIT.PA - making it one of the few video QA companies with a public market valuation.
Witbe's client list reads like a who's-who of Western streaming infrastructure: Comcast, Verizon, Cox, Peacock, Orange. These aren't logo-on-a-slide clients. They're operations teams that rely on Witbe's robots to catch problems before a million subscribers see them.
In 2022 - Witbe's record year - the company posted EUR 26.1 million in revenue, a 36% jump. The following years brought the AI pivot, a Singapore APAC headquarters, and a cascade of industry awards that Planche has described as validation of the company's shift from monitoring hardware to intelligent automation.
The Nanterre-headquartered company now operates 12 offices spanning Paris, New York, San Francisco, Denver, Montreal, Singapore, London, and Sao Paulo.

Education
The dual-degree path - a prestigious French grande école combined with a top US research university - gave Planche an unusual combination: deep theoretical grounding in electrical engineering and practical computer science from one of America's most technically rigorous programs. He was consulting at Witbe while completing both degrees simultaneously.
The Bigger Picture
Witbe's 25-year runway means Planche is building on a foundation that predates every major streaming service his robots now monitor. That history is an advantage - and a responsibility.
The streaming wars produced an arms race in content and distribution. They didn't produce an arms race in quality assurance. That gap is where Witbe operates - and where Planche has spent his tenure widening the moat.
Witbe's robots don't just watch streams. They run the full user journey: open the app, search for a title, start playback, insert an ad, switch quality levels, change the channel. Every action a real viewer takes, replicated continuously across thousands of real devices in real homes and data centers. The moment something breaks - an ad fails to match, a 4K stream drops to 1080p without warning, a voice command misroutes - Witbe's system fires an alert before the first complaint arrives.
The Agentic AI launch in 2024 was the logical next step: if you have robots that can run tests, why not give them agents that can design and interpret those tests without human scripting? The "Designer, Runner, Analyst" architecture means Witbe's QA workflows can adapt to UI changes across streaming apps without a team rewriting test scripts every time Netflix updates its app.
At IBC 2025 in Amsterdam, Planche's team presented field results showing real-world deployment of agentic test automation - not a demo, but actual production data from clients. That's the Witbe pattern: ship it, prove it, then show the receipts at the trade show.
The challenge ahead is familiar territory for any infrastructure-layer company: staying invisible when everything works, while being indispensable when it doesn't. For a CEO who came up through operations and product, that balance is something Planche has been calibrating for over a decade.
