Sandbar, a New York–based interface startup, has raised US$23 million in Series A funding to develop a wearable device that lets people interact with artificial intelligence via voice rather than screens.
Adjacent and Kindred Ventures led the round; both venture firms focused on early-stage technology startups. The investment brings Sandbar’s total funding to us$36 million. Earlier backing included a US$10 million seed round led by True Ventures, a venture capital firm, as well as a US$3 million pre-seed round supported by Upfront Ventures, a venture firm and Betaworks, a startup studio and investment firm.
Sandbar was founded by Mina Fahmi and Kirak Hong, who previously worked together at CTRL-labs, a neural interface startup acquired by Meta in 2019. Their earlier work explored how computers could respond more directly to human intent — an idea that continues to shape Sandbar’s approach to AI interfaces.
The new funding will help the company expand its team across machine learning, interaction design and software engineering as it prepares to launch its first product. That product, called Stream, combines a wearable ring with a conversational AI interface. The system allows users to speak to an AI assistant without unlocking a phone or opening an app.
The concept is simple. Instead of typing into a screen, users press a button on the ring and talk. The system can capture notes, organize ideas, retrieve information from the web or trigger actions through connected applications.
The ring includes a microphone, a touchpad and subtle haptic feedback. These elements allow the device to respond through gentle vibrations rather than visual alerts. According to the company, the ring only listens when the user presses the button — a design meant to address common concerns around always-on microphones.
That design reflects a larger shift Sandbar believes is underway. As AI assistants become more capable, many startups are experimenting with new ways to interact with them. The focus is moving away from screens and keyboards toward interfaces that feel more natural and immediate.
Stream uses multiple AI models working together to process requests, search the web and structure information in real time. The company says users remain in control of their data and can choose whether to share information with other apps.
Sandbar is also developing a feature called Inner Voice, which responds using a voice customized to the user. The feature will debut during a closed beta planned for this spring, giving the company time to refine how the software behaves in everyday use.
The startup currently employs a team of 15 people. Many have worked on well-known consumer devices including the iPhone, Fitbit, Kindle and Vision Pro. Recent hires include Sam Bowen, formerly of Amazon and Fitbit, who joined as vice president of hardware and Brooke Travis, previously at Equinox, Dior and Gap, who now leads marketing.
Sandbar plans to begin shipping Stream in summer 2026 after completing early testing. As artificial intelligence tools become more integrated into daily life, the company is betting that the next shift in computing will not come from another app — but from new ways for people to interact with AI itself.

A closer look at PMMI’s FastTrack initiative and why it matters for growing manufacturing firms

Large trade shows are built for scale. But for small and medium-sized manufacturers, that scale often creates distance between what’s on display and what they can actually use. Too many options, too little time, and very few tools designed for companies that are still growing. That mismatch is what PMMI is trying to correct with its new SMB FastTrack Program at PACK EXPO East 2026.
That is the problem PMMI is trying to address with its new SMB FastTrack Program, launching at PACK EXPO East 2026 in Philadelphia.
PMMI — the Association for Packaging and Processing Technologies — is the industry body behind the PACK EXPO trade shows and a central organization in the global packaging and processing sector. Through FastTrack, it has created a program (not an app or a product) designed to help small and mid-sized companies navigate the show more efficiently and connect with solutions that fit their scale.
The idea behind SMB FastTrack is simple: reduce friction. Instead of asking smaller firms to sort through hundreds of exhibitors and sessions on their own, the program curates what is most relevant to them. Exhibitors that offer flexible pricing, right-sized machinery, or SMB-focused services are clearly identified with visual icons in both the online directory and on the show floor. That way, a small manufacturer can quickly distinguish between enterprise-only vendors and partners that are realistically accessible.
The same logic carries into education. Rather than treating all attendees the same, PACK EXPO East 2026 will include a learning track specifically built around SMB realities. These sessions focus on issues that smaller teams actually face—how to hire and train workers, use AI without over-investing, improve food safety, cut operating costs, and adopt technology in stages. The goal is not inspiration, but applicability: content that reflects real constraints, not ideal scenarios.
Planning, too, is built into the structure of the program. Through a dedicated FastTrack landing page, participants can access curated supplier lists, recommended sessions, and planning tools that help organize their time before they ever step onto the show floor. Tools like category search and sustainability finders are meant to narrow choices quickly, turning a massive event into something manageable.
Seen together, these elements point to a broader intention. PMMI is not simply adding features—it is reshaping how smaller manufacturers experience a major industry event. Instead of competing for attention in a space built for scale, SMBs are given clearer paths to the people, tools, and knowledge that match where they actually are in their growth cycle.
What makes SMB FastTrack notable is not the technology behind it, but the intention behind it. PMMI is recognizing that progress for small and mid-sized manufacturers depends less on spectacle and more on fit—solutions that are accessible, affordable, and adaptable. The program is designed to help companies move with purpose, not pressure.
In an industry where visibility often follows size, SMB FastTrack represents a structural shift. It treats small and medium-sized manufacturers not as a subset of the audience, but as a distinct group with distinct needs. By doing so, PMMI is quietly redefining what a trade show can be: not just a marketplace of innovation, but a usable platform for companies still building their next stage of growth.
