Sesame, the conversational AI startup founded by former Oculus executives, launched its iOS app today after raising $250 million in Series B funding, marking a pivotal step toward its vision of blending AI companionship with wearable technology.
For years, AI chatbots have been trapped in the same awkward rhythm: rapid-fire responses that feel robotic or deliberate pauses that feel unnatural. Sesame is betting that the future of AI lies somewhere in between—a conversational agent that thinks aloud, pivots mid-sentence, and mimics the cadence of human speech. The company’s new iOS app, now available in a public preview, is its first major test of that philosophy. But the real prize? Lightweight smart glasses designed to turn AI from a screen-based tool into an always-present companion.
An AI That Feels Like a Person (Not a Bot)
Sesame’s approach to conversational AI is radical in its simplicity: it refuses to sacrifice thoughtfulness for speed. As the company puts it, “There’s an inherent tension between replying quickly and taking the time to compose thoughtful responses. A slower response is usually more correct, but it can also feel unnatural if it takes too long.” To bridge that gap, Sesame has built what it calls “fast search and retrieval systems” that allow its AI agents to process information in real time—even while speaking. The result? An AI that can weave new facts into a conversation mid-flow, much like a human might remember an additional point in the middle of a sentence.
That’s a far cry from today’s chatbots, which often deliver responses in bursts or struggle to incorporate new information dynamically. Sesame’s technology, however, doesn’t just translate text-to-speech—it generates speech directly, capturing “the rhythm, emotion, and expressiveness of real dialogue,” according to investor Sequoia Capital, which led the $250 million Series B round. The company demonstrated this capability in a 2025 beta with two AI agents, Maya and Miles, which attracted over a million users within weeks and logged more than 5 million minutes of conversation. Early testers described the experience as “genuinely fun” and “natural-sounding,” with one Yahoo Tech report calling it “unlike anything we’d used before.”
The iOS app introduces four distinct AI agents—Maya, Miles, Simone, and Charlie—each with its own voice, personality, and memory. Users can interact via voice, text, or a hybrid mode, and the app includes features like search cards with visual results, note-taking tools, and an incognito mode for private conversations. But the real innovation lies in Sesame’s long-term vision: turning these agents into “actionable companions” that can observe the world alongside users—likely through its upcoming smart glasses, slated for a 2027 launch.
The Oculus Team’s Second Act: From VR to AI Glasses
Sesame’s founding team reads like a who’s who of Oculus and Meta’s hardware leadership. Brendan Iribe, the former CEO of Oculus, co-founded the company alongside Ankit Kumar (ex-CTO of AR startup Ubiquity6), Nate Mitchell (Oculus co-founder and chief product officer), and Hans Hartmann (former Oculus COO and Fitbit executive). This isn’t just another AI chatbot—it’s a bet on the next frontier of consumer tech: “an assistant that understands context, lives alongside you, and helps you navigate daily life,” as LinkedIn post by Derek Weber framed it, echoing Tony Stark’s fictional AI, Jarvis.
The team’s Oculus pedigree isn’t just about credibility—it’s about execution. They’ve already proven they can ship hardware at scale (Oculus sold to Meta for $2 billion in 2014), and they’re applying that expertise to a new challenge: making smart glasses that people will actually wear. The key? Fashion-forward design. As Sequoia noted in its investment announcement, “hardware takes time,” but the goal is clear: glasses that look like accessories, not gadgets. Early descriptions emphasize “high-quality audio” and “lightweight, fashion-forward” frames—a direct response to the clunky reputation of past AR glasses like Google Glass.
Sesame isn’t alone in this race. OpenAI is collaborating with Apple design legend Jony Ive on AI-native devices, while Meta is doubling down on its Ray-Ban Meta glasses. But Sesame’s edge may lie in its focus on the “experience layer”—not just raw AI power or ecosystem scale, but the “feeling of interacting with AI”, as Weber put it. In a market flooded with chatbots, the company is betting that consumers will pay for an AI that feels like a companion, not a tool.
What the iOS App Reveals About Sesame’s Ambitions
The iOS app is more than a demo—it’s a proof of concept for how Sesame’s technology will work in the real world. Users can engage with the AI agents in three modes: voice, text, or a hybrid “search, text, and think” mode. This flexibility addresses a critical flaw in today’s AI assistants: they often force users into rigid interaction styles. Sesame’s approach mirrors how humans communicate—sometimes we speak, sometimes we type, and sometimes we need to pause and reflect.
But the app also hints at where Sesame is headed. Features like “incognito mode” (which retains context but saves nothing to memory) and “deep dive” capabilities suggest the company is designing for scenarios where privacy and nuance matter. The app’s four distinct agents—each with unique personalities—also signal a shift away from the generic, one-size-fits-all AI of today. Maya might be analytical, while Charlie could be more casual; the goal is to match the AI’s tone to the user’s needs, much like how we adjust our speech depending on who we’re talking to.
Most importantly, the app serves as a testing ground for Sesame’s core philosophy: “natural-sounding” AI that observes the world alongside you. While the iOS version is limited to conversation, the company has hinted that future iterations will integrate with sensors and cameras—turning the AI from a passive listener into an active participant in daily life. Imagine asking your glasses AI to summarize a meeting in real time, or to flag important details as they happen. That’s the vision Sesame is chasing.
The $250 Million Bet: Why Investors Are All-In
Sesame’s $250 million Series B round—led by Sequoia with participation from Spark and other backers—reflects more than just hype. It’s a vote of confidence in a specific vision of AI’s future: one where the technology is embedded in our daily lives, not just confined to screens. Sequoia’s post on the investment called Sesame’s conversational layer “different” because it “doesn’t just translate LLM output into audio—it generates speech directly”, capturing the nuances of human dialogue. That’s a rare endorsement in a sea of AI startups chasing the same buzzword.
The funding also underscores the stakes in the AI hardware race. While companies like Apple and Meta focus on building ecosystems, Sesame is betting on “the experience layer”—the intangible but critical factor that determines whether users adopt a product. As Weber noted, “Consumers will choose what resonates with them.” In a market where AI assistants are still clunky and chatbots feel impersonal, Sesame’s approach—prioritizing natural interaction over raw intelligence—could be the differentiator.
But the real test will come with the smart glasses, expected in 2027. Hardware is notoriously difficult to perfect, and Sesame’s timeline suggests the team is aware of the challenges. Still, the company’s track record—from Oculus to Ubiquity6—gives it a leg up. If they can deliver on their promise of “fashion-forward” glasses with “high-quality audio” and an AI that feels like a true companion, they could redefine how we interact with technology.
What Comes Next: The Road to 2027 and Beyond
Sesame’s iOS app is just the beginning. The company has made it clear that its ultimate goal is to create an AI agent that doesn’t just respond to commands but “observes the world alongside you”. That means integrating sensors, cameras, and context-aware processing into its smart glasses—essentially turning the wearer’s vision into a shared experience with the AI.
- 2026: Refining the iOS app based on beta feedback, with a focus on expanding the four AI agents’ capabilities (e.g., more personalized responses, better integration with third-party apps).
- 2027: Launch of the smart glasses, with a design prioritizing both functionality and fashion. The AI companion will need to handle real-world tasks—summarizing meetings, identifying objects, or even providing real-time guidance—without feeling intrusive.
- 2028+: Potential expansion into enterprise or healthcare applications, where contextual AI could have broader utility (e.g., assisting doctors with patient notes or training workers in complex tasks).
The biggest question isn’t whether Sesame’s technology will work—early reviews suggest it does—but whether consumers will embrace AI glasses as more than a novelty. The market has seen failed attempts before (Google Glass, anyone), but Sesame’s focus on “natural-sounding” AI and fashion-forward design gives it a shot. If they can make the experience feel seamless and valuable, they could carve out a niche in a crowded field.
One thing is certain: the race to build the next generation of AI companions is on. OpenAI’s Jony Ive collaboration, Meta’s Ray-Ban glasses, and now Sesame’s iOS app all point to a future where AI isn’t just a tool we use—it’s a presence we live with. The company that gets the balance right between intelligence and humanity may just redefine what it means to have an assistant.
For now, Sesame’s iOS app is a glimpse into that future. And if the early reactions are any indication, it’s one worth watching.
