Relay has secured $36 million in new funding to expand its system designed for physical operations. This round brings the company's total raised capital to over $90 million. International Paper, a Fortune 500 packaging manufacturer with over 125 years of production experience, led this round.
New investors include clients Cerity Partners, Harmonic Growth Partners, and Thayer Investment Partners. Existing investors, such as G2 Venture Partners and Wind River Ventures, also increased their investments. Relay reported that the round was significantly oversubscribed.
The company characterized this funding as a strong fit for industries utilizing its technologies. Chris Chuang, CEO and co-founder of Relay, noted that customers are also investing in the company. He highlighted International Paper's experience using Relay in complex industrial environments.
Physical operations still heavily rely on frontline workers communicating through verbal interactions, much of which does not enter traditional digital systems. A Relay study involving 500 manufacturing professionals identified this gap. Approximately 57% of respondents stated that the most critical operational communication happens out loud and in person. Only 17% reported that almost everything workers notice gets logged into a system, journal, or official report. Relay terms this lost operational information as 'signal evaporation.'
Furthermore, the company found that 79% of respondents regularly encounter communication breakdowns. Such failures can lead to delays, rework requirements, and missed task handoffs. Relay uses standard push-to-talk radio systems to record on-site communications.
The Relay platform integrates cloud communication, artificial intelligence, translation, location tracking, and automated workflows. The system supports 35 languages and utilizes specialized hardware for challenging work environments. Relay's goal is to connect workers' verbally expressed knowledge with existing operational systems. The company serves hundreds of thousands of frontline workers across various sectors, including manufacturing, hospitality, and healthcare. Relay collaborates with approximately 10% of Fortune 500 companies.
Some large enterprise clients use the Relay platform for over 10,000 users. Weekly, Relay processes over a billion data points across nearly 10,000 deployed sites. The company's enterprise client base also demonstrates gross revenue retention at 99% and net revenue retention at 130%. International Paper applies Relay in harsh industrial settings, using the platform for communication, shift handovers, safety alerts, and maintenance response. Thayer Investment Partners also notes growing adoption in the hospitality sector, as their partners represent leading hotel, resort, and casino brands.
Relay plans to use the new funding to accelerate the development of its software capabilities and AI features. The company intends to create an analytics layer and an agent layer for operational data, allowing teams to query shift information and take appropriate action. Additionally, Relay plans to expand worker safety solutions and integration with enterprise systems. The company will also develop the next generation of hardware for frontline workers in physical workplaces and expand its presence in the industrial and hospitality markets. Additional funding will be directed toward hiring product and go-to-market teams.
Relay has been recognized on the Deloitte Technology Fast 500 list for three consecutive years. Recently, the company ranked 830th on the Inc. 5000 list as one of America's fastest-growing private companies, marking its third year on the list. Relay's broader platform is designed to transform frontline workers' verbal communication into actionable operational outcomes, helping businesses connect human knowledge with automation and artificial intelligence.
