The VR industry's most successful founder is betting big on voice AI. Brendan Iribe, who built Oculus into a $2 billion acquisition by Facebook, just secured $250 million for Sesame, his conversational AI startup developing smart glasses that respond to natural speech. The Series B round from Sequoia Capital and Spark Capital positions Sesame to challenge Meta's own AR ambitions with technology that early testers are calling 'genuinely fun.'
The smart glasses wars just got a heavyweight contender. Sesame, the conversational AI startup led by former Oculus co-founder and CEO Brendan Iribe, announced a $250 million Series B round Tuesday while simultaneously opening beta access to its voice-powered AI companion.
The timing isn't coincidental. As Meta doubles down on expensive VR headsets and Apple stumbles with its $3,500 Vision Pro, Sesame is pursuing a different strategy: lightweight glasses you'd actually want to wear, powered by AI voices so natural they feel human.
"The experience was unlike anything we'd used before," Sequoia Capital wrote in a blog post explaining their investment. "Sesame's conversational layer felt different. It doesn't just translate LLM output into audio—it generates speech directly, capturing the rhythm, emotion, and expressiveness of real dialogue."
That's not marketing speak—the numbers back it up. When Sesame emerged from stealth in February with AI voices named "Maya" and "Miles," over a million people accessed the demos within weeks, generating more than five million minutes of conversation. The Verge called the experience "genuinely fun" and "natural-sounding" after hands-on testing.
Iribe isn't starting from scratch. His founding team reads like an Oculus reunion: co-founder Nate Mitchell serves as Chief Product Officer, former COO Hans Hartmann (who also led operations at Fitbit) runs day-to-day operations, and Reality Labs engineering director Ryan Brown leads technical development. The roster also includes longtime Facebook and Meta executive Angela Gayles.
This hardware expertise matters enormously. While AI voice assistants have improved dramatically, wearable implementations remain clunky. Amazon's Echo Frames flopped, Google Glass became a cautionary tale, and even Meta's Ray-Ban collaboration focuses more on cameras than conversation.
Sesame believes the secret lies in making glasses people actually want to wear. As Sequoia noted, the company is building "fashion forward" eyewear that looks good even without AI features. "Hardware takes time," the firm acknowledged, but Iribe's team has shipped consumer hardware before—and sold it for $2 billion.
The beta launch strategy reveals Sesame's confidence in their technology. Starting Tuesday, select iOS users can access an early version of the AI companion through a dedicated app that can "search, text and think," according to Iribe's announcement on X. Beta testers must sign confidentiality agreements, suggesting features that could surprise competitors.
The competitive landscape is heating up fast. OpenAI recently demonstrated Advanced Voice Mode that rivals human conversation, while Anthropic and Google race to improve their own voice assistants. Hardware players like Humane and Rabbit have struggled with execution, creating an opening for experienced teams.
Sesame's $250 million war chest—with additional undisclosed investors beyond Sequoia and Spark Capital—positions them to avoid the hardware startup death spiral. Building consumer electronics requires massive upfront investment, manufacturing expertise, and retail relationships that have crushed well-funded competitors.
The smart glasses market represents a massive opportunity if executed correctly. While VR remains niche and AR headsets feel futuristic, lightweight glasses with AI companions could become as essential as smartphones. Early adoption will likely focus on productivity use cases before expanding to entertainment and social applications.
Industry watchers should monitor Sesame's beta feedback closely. If users genuinely prefer conversing with AI through glasses over smartphones, it could accelerate the entire wearables category. The company's Oculus pedigree suggests they understand consumer adoption curves better than most hardware startups.
Sesame's massive funding round and beta launch signal that conversational AI is moving beyond smartphones into wearables. With proven hardware leadership from the Oculus team and backing from top-tier VCs, the startup is positioned to challenge both Big Tech incumbents and struggling hardware startups. The real test will be whether consumers embrace talking to AI companions through glasses—but if anyone can crack that code, it's the team that made VR mainstream.
