For more than a decade, if you were deaf in America and needed to relay a text message into a voice call—say, to schedule a doctor's appointment or navigate a customer service line—T-Mobile was the dominant provider, though other companies received conditional certifications during this period.
That landscape shifted significantly on June 9, when Rylo, an Israeli-American startup barely five years old, secured full Federal Communications Commission certification to operate automated relay services nationwide. The same day, perhaps not coincidentally, the company announced an $85 million funding round. Israeli media outlets Calcalist and AT Partners reported a valuation of roughly $500 million, though Rylo hasn't confirmed the figure publicly.
It's a remarkable trajectory for a company that started life as Nagish—Hebrew for "accessible"—and only recently rebranded. Now backed by General Catalyst's Customer Value Fund and Canaan, with total capital raised exceeding $100 million, Rylo is making an ambitious wager: that artificial intelligence can reshape how millions of people communicate across barriers of hearing and language.
Whether the technology is ready for that role—and whether users will trust machines over human interpreters—remains an open question.
The Regulatory Breakthrough
The FCC certification matters more than typical startup regulatory wins. It grants Rylo a five-year license, through June 2031, to provide Internet Protocol Captioning Telephone Service (IP CTS) and IP Relay using fully automated systems: automatic speech recognition for live captions, text-to-speech for outbound calls. More importantly, it unlocks access to the FCC's Telecommunications Relay Services Fund, which reimburses providers on a per-minute basis at rates the agency sets.
That's a revenue stream few venture-backed companies can claim—essentially, government reimbursement for every minute of service delivered.
The IP Relay certification is especially significant. Between 2014 and 2026, T-Mobile (which inherited Sprint's relay operations) operated as the sole provider, according to FCC records. Rylo's entry marks the first new competitor in that market in over a decade.
The company's pitch emphasizes privacy: by eliminating the human call centers that traditional relay services use, Rylo says it can avoid the awkwardness—and potential security risks—of having strangers listen in on personal conversations. It's a compelling argument, though one that assumes automated systems can handle the nuance and complexity of real-time human communication as effectively as trained operators. The jury's still out on that.
Building Momentum, Quietly
CEO Tomer Aharoni and CTO Alon Ezer founded the company in 2021, though it took until January 2024 to secure conditional FCC certification for IP CTS. By July of that year, they'd raised $16 million in total funding, including an $11 million Series A from Canaan Partners. The pitch was working: enterprise customers including Comcast, Pfizer, NBCUniversal, and Amazon had begun deploying the platform, according to company announcements at the time.
Then things accelerated. Last October, Rylo acquired Sign.mt, a sign-language translation startup, bringing aboard Dr. Amit Moryossef as Head of Research. That deal set the stage for "Rylo Sign," which the company says will eventually support translation between dozens of signed and spoken languages—a feature set that, if it works, could address chronic interpreter shortages in healthcare, education, and legal settings.
At least, that's the vision. The deaf community has historically approached AI-powered sign language tools with caution, and for good reason: signed languages are rich, context-dependent systems that don't map neatly onto spoken language syntax. Whether machine learning models can truly bridge that gap is still being debated.
A Crowded Field, A Massive Market
Rylo's $85 million raise positions it to scale quickly, funding FCC-certified captioning services and what the company describes as a broader AI communication suite. The roadmap is ambitious: workplace accessibility tools, sentiment analysis, fraud detection, speaker characteristic analysis, network improvements. It reads like a product team's wish list, though which features will gain traction—and which will quietly disappear—remains to be seen.
The market opportunity is undeniably large. Somewhere between 48 and 50 million Americans experience hearing loss, according to the Hearing Loss Association of America. Globally, the World Health Organization puts the figure at 430 million people with disabling hearing loss, a number projected to surpass 700 million by 2050 as populations age.
But opportunity doesn't mean open field. IP CTS providers like ClearCaptions, CaptionCall by Sorenson, Hamilton CapTel, and InnoCaption have been serving this market for years. Consumer tech giants, meanwhile, have introduced features like Android Live Caption—free, on-device captioning that operates outside the FCC's regulatory framework entirely.
Rylo's advantage, if it holds, is regulatory: access to that TRS Fund revenue stream, combined with venture capital that lets it move faster than traditional telecom-era providers. With 32 employees split between New York and Tel Aviv, support for roughly 50 languages, and what the company claims are hundreds of thousands of U.S. users, it's still small. But it has resources now.
Existing investors Vertex Ventures and Contour joined the round, alongside newcomers Cardumen Capital and K5 Global. Israeli media outlets Calcalist and AT Partners pegged the company's valuation at approximately $500 million, though Rylo hasn't confirmed the figure publicly.
The Billion-Dollar Question
According to media reports citing management projections—unconfirmed by the company—Rylo is targeting around $100 million in annual recurring revenue by the end of 2026 and $1 billion by 2028. Those are aggressive targets for a company that, two years ago, was still navigating conditional FCC approval.
Then again, aggressive is how the venture game works. General Catalyst doesn't write $85 million checks expecting modest outcomes.
There's a minor branding hiccup to navigate: a defunct 360-degree camera startup, also called Rylo, was acquired by VSCO in 2019 and still appears in iOS app stores. Search "Rylo" and you might land on an obsolete camera app before finding the accessibility platform. The Android app has already rebranded to "Rylo: Live Call Captions," but the iOS transition is ongoing. It's the kind of detail that won't matter much if the company succeeds—and will seem amusingly shortsighted if it doesn't.
For now, Rylo is betting that AI can do what human interpreters and traditional relay services have struggled to scale: real-time, multilingual, accessible communication for millions of people who've been shut out of conventional phone networks. With regulatory approval, substantial capital, and a competitive market watching closely, the next chapter will reveal whether the technology—and the business model—can deliver on that promise.
