"Rylo raises $85M to expand AI communication tools for deaf and hard-of-hearing users
The company, formerly known as Nagish, said the funding will support its expansion from phone-call captioning into a broader AI-powered communication platform.


The financing includes growth funding from General Catalyst’s Customer Value Fund, along with a new investment by Canaan and participation from existing investors Vertex Ventures and Contour.


The company said the round brings its total financing to more than $100 million.


WHAT IT DOES


Founded in 2021 as Nagish, Rylo offers an FCC-certified platform that provides real-time captioning and text-to-speech capabilities for phone calls and in-person communication.


The company said its Rylo Phone app will continue to offer those core features while it develops additional AI-powered tools for workplace accessibility, network improvements, speaker characteristics, sentiment analysis and real-time fraud detection.


The rebrand reflects the company’s planned expansion beyond phone call captioning into a broader communication platform for deaf and hard-of-hearing users, Rylo said in a statement, also noting the name Rylo combines the concepts of "relay" and "rely."


MARKET SNAPSHOT


In 2024, Rylo announced $16 million in funding, including an $11 million Series A and $5 million in seed funding.


Rylo acquired Sign.mt in 2025, a company focused on real-time sign language translation. That acquisition helped lead to Rylo Sign, an AI-powered sign language platform designed to support translation between signed and spoken languages.
