Relay Builds the AI Layer for Frontline Operations

TL;DR: Relay is building an operating layer for the physical workforce. Led by co-founders Chris Chuang, CEO, and Jim Mulcahy, President, the Raleigh company combines purpose-built wearable devices, cloud software, AI translation, worker-safety tools, and operational intelligence for teams that cannot work from a laptop.

Relay says its system is live at nearly 10,000 sites, serves more than 40 Fortune 500 companies, and processes over one billion data points each week. The company has raised more than $90 million, including a new $36 million financing announced in September 2026, and its careers board listed 32 openings at the time of this review.

The larger story is not a better walkie-talkie. Relay is trying to turn voice, location, alerts, and frontline activity into structured information that an enterprise can act on. That puts the company at the intersection of industrial AI, communications, safety, and the long-delayed digitization of deskless work.

About Relay

Relay evolved from within Republic Wireless, itself a spinout of Bandwidth. The company is headquartered in Raleigh, North Carolina, and is led by Chris Chuang and Jim Mulcahy, experienced entrepreneurs who previously worked together on the Wi-Fi-first mobile carrier.

That history matters. Relay did not start by adding a chatbot to an industrial dashboard. It began with the harder physical problem of keeping mobile workers connected across changing networks and demanding environments. Its current system pairs the RelayX and RelayM wearable devices with cloud software for team communications, worker safety, location awareness, translation, fleet management, and operational reporting.

The result is a hardware-enabled software platform designed for people in manufacturing plants, warehouses, hotels, hospitals, casinos, venues, and other physical operations. Those workers are often beyond the reach of email, conventional business software, and the data trails generated by desk-based work.

From Voice Traffic to Operational Intelligence

Traditional radios move voice from one person to another, then discard the exchange. Relay's thesis is that frontline communication contains valuable operating context: where help is needed, what interrupts a shift, which incidents repeat, and how teams respond.

The Relay SOAR platform is designed to capture those signals and turn them into searchable, usable information. Relay says the system now processes more than one billion data points every week. Its AI channel-scanning and reporting tools can monitor operational streams and summarize shift or incident activity, creating a bridge between the people doing the work and the systems their managers already use.

This is a meaningful category shift. A connected device may replace a radio, but an operational data layer can influence safety, staffing, training, response times, and process design. Relay is competing to own that layer before legacy communications vendors or horizontal software platforms reach the frontline.

Communication, Safety, and Language in One System

Relay's products are built around three practical jobs: keeping teams connected, helping workers summon and locate assistance, and making frontline activity legible to operators.

RelayX combines cellular and Wi-Fi connections with rugged hardware, group and one-to-one messaging, location features, safety alerts, and a screen designed for demanding environments. RelayM carries similar capabilities in a smaller form factor aimed at hospitality and other customer-facing settings.

TeamTranslate adds real-time voice translation across more than 30 languages. The feature is not a novelty when teams need to coordinate during an equipment problem, guest incident, or safety event. Relay reported that TeamTranslate usage grew more than 500 percent year over year, while 78 percent of new industrial customers adopted AI features. Those figures are company-reported, but they show where Relay believes its advantage is moving: from connectivity alone toward software and intelligence.

Traction Beyond the Device

Relay reported 461 percent revenue growth over three years and ranked No. 175 on the 2025 Deloitte Technology Fast 500. Its official company page says the platform is deployed across nearly 10,000 sites and used by more than 40 Fortune 500 companies. Relay also says 47 percent of revenue comes from customers with at least $100,000 in annual recurring revenue, with net revenue retention above 135 percent among those enterprise accounts.

These are company-reported operating metrics, not independently audited financial disclosures. Taken together, however, they point to an enterprise platform expanding within large customers rather than a device vendor living on one-time hardware sales.

The $36 million financing announced in September 2026 brings Relay's total capital raised above $90 million. Customer International Paper led the investment, alongside new and returning financial investors. A customer leading the round is strategically notable because it connects capital to firsthand product use, although it does not remove the execution risk ahead.

Leadership and the Hiring Signal

Chris Chuang serves as co-founder and CEO, and Jim Mulcahy is co-founder and President. Relay also added Matthew Welch as Chief Marketing Officer and Shiv Hira as Chief Financial Officer in 2026, bringing experience in hardware-enabled software, public-company finance, and businesses that scaled toward major liquidity events.

Hiring provides another view of the plan. Relay's current careers board listed 32 open roles during this review across finance, security, people operations, customer success, sales, and other functions. The company says it employs nearly 300 people in Raleigh and beyond.

The role mix suggests that the next phase is not only about building devices. Relay is adding the commercial, customer, financial, and operational capacity required to support complex enterprise deployments. That is a demand signal, not proof of future growth, and the company still has to turn new headcount into durable customer outcomes.

Why Relay Matters Now

Enterprises have spent years digitizing finance, sales, marketing, and software development while many physical workflows still run through radios, paper, memory, and improvised escalation chains. AI cannot improve a process it cannot observe. Relay's opportunity is to make the frontline observable without forcing workers to become data-entry clerks.

That opportunity also creates the main risk. Hardware must survive harsh conditions. Networks must remain available. Safety features must work when consequences are real. AI summaries cannot distort an incident, and workers need clear privacy boundaries around the voice and location data the platform captures.

Relay's advantage is that it has spent years building from the device outward. Its challenge is proving that the resulting data and intelligence layer can become a durable enterprise system rather than an expanded communications product.

The company now has the capital, customer footprint, product range, and hiring activity to test that ambition at scale. If Relay succeeds, the walkie-talkie will not merely get smarter. It will become the interface through which physical operations finally join the software-defined enterprise.
