UJET Wants to Kill the Call Center Mitel Helped Build

There is a version of the customer service story where artificial intelligence answers every call, no one waits on hold, and the humans quietly disappear. UJET is not selling that version. The San Francisco company has spent a decade arguing that the contact center was designed wrong from the start, and that fixing it has less to do with replacing people than with untangling the mess of software sitting in front of them. That argument now runs straight into Mitel, a company that has been building the other kind of contact center for roughly fifty years.

Put the two side by side and you get a clean picture of where customer experience is actually heading. UJET was founded in 2015 by Anand Janefalkar, an engineer who came up through Motorola and Jawbone. His starting complaint was simple: the contact center had barely changed since the 1990s, even as everything about how people communicate had. Phones became pocket computers. Support moved to chat, to apps, to whatever channel a customer already had open. The switchboard stayed a switchboard.

Mitel, by contrast, is one of the companies that built the switchboard era and lived through every version of it. Founded in the early 1970s, it grew into a telephony and unified-communications heavyweight, absorbed the enterprise comms business of Unify from Atos in 2023, and today leans heavily on partnerships - with Five9, with NICE CXone, with Zoom - to give its large installed base a path to the cloud. It is the incumbent's playbook, and it works. But it is a different bet than UJET's.

01The word "3.0" is doing a lot of work

UJET describes its product as "CCaaS 3.0" - contact center as a service, third generation. It is a marketing phrase, and a clever one, because it quietly labels everyone else as version one or two. But there is a real idea underneath it. Version one was the on-premises phone system. Version two moved that system to the cloud, mostly unchanged. UJET's claim is that the third version starts from the device the customer is already holding and treats voice as one channel among many, wired together by software rather than by a physical exchange.

That framing matters because it turns a feature argument into a category argument. You do not compete with UJET by adding one more integration. You compete by convincing a buyer that their current system is fundamentally an older generation. It is the same move that reshaped databases, payments, and developer tools - attack the assumption, not the product.

Naming is strategy, and UJET's is unusually literal. The company reads as "you jet" - a promise about speed folded into the logo before a buyer has seen a single feature. That kind of choice signals what a company believes it is selling. Mitel, born in a different decade, carries a name that sounds like infrastructure, because infrastructure is what it built. Neither is an accident. The words a company picks tend to harden into the story it tells for the next twenty years, and both of these companies are living inside the stories they named themselves after.

The customer roster tells the same story as the pitch. UJET's publicly cited names - Instacart, Turo, Wag!, Atom Tickets - are app-native brands that never ran a traditional phone room and never wanted one. For a company like that, "move your switchboard to the cloud" is meaningless advice, because there was no switchboard. That is the wedge UJET has been driving for a decade.

02Growing up in public

In 2024, UJET raised a $76 million Series D, reportedly at a $500 million valuation, led by Sapphire Ventures with participation from GV, Kleiner Perkins, Citi Ventures and others. Around the same time, it made a leadership change that is easy to skim past and worth reading closely. Vasili Triant, a telecom and contact-center veteran who had run contact-center businesses at Cisco and served as CEO of Serenova, was elevated to co-CEO and then, in April 2025, to sole CEO. Founder Janefalkar stepped into the roles of Chairman and Chief Evangelist.

There is a pattern there that shows up again and again in enterprise software. When a founder becomes the "evangelist" and an operator with a long sales-and-scale resume takes the CEO seat, the company is telling you something: the idea is proven, and the job now is distribution. UJET stopped arguing that CCaaS 3.0 should exist and started trying to sell it into the accounts that incumbents like Mitel have held for years.

03The Spiral move

In November 2025, UJET acquired Spiral, a conversational-analytics company started by former Amazon engineers. Spiral's job is to take the unstructured pile of a support operation - calls, chats, emails, surveys, reviews - and connect large volumes of conversation to the specific issues driving them. The clever part of the deal is what UJET did with it. Spiral's technology was folded into the core platform, and it was also kept alive as a standalone product, "Spiral by UJET," still actively sold on its own.

One acquisition, two revenue lines: a feature that deepens the platform, and a product that can walk into accounts that have never heard of UJET. It is a quiet, efficient way to buy both capability and a new front door at the same time.

04Orchestration over infrastructure

The clearest statement of UJET's bet arrived in March 2026 with Agentic Experience Orchestration, or AXO. Strip away the acronym and the idea is almost mundane, which is usually a good sign. Most of the pain in a modern contact center is not that the AI is bad. It is that the human agent is drowning - a dozen browser tabs, three systems that do not talk to each other, a customer waiting while the person supposed to be helping them hunts for a record. AXO is pitched as a single layer that unifies the data and the AI, automates the busywork, and shrinks the number of separate systems an agent has to touch.

Analysts have described it as a bet on orchestration over infrastructure, and that phrase captures the whole strategy. Mitel, and the broader telephony world it represents, sells infrastructure - the reliable plumbing that connects a call to a person. UJET is arguing that the value has moved up a layer, to the software that decides what happens once the connection is made. Both companies are, from different directions, arriving at the same question: what does a human agent actually do once an AI answers first?

It is worth being precise about why the agent angle is the interesting one. The loudest version of the AI story treats support staff as a cost to be removed, and plenty of vendors have leaned into exactly that. UJET's leadership has taken the opposite public position - keep the people, remove the friction - which is either genuine conviction or shrewd positioning, and probably a bit of both. Either way it is a more defensible place to stand, because a buyer who has watched an all-automation rollout frustrate customers is primed to hear a pitch about helping agents instead of firing them.

None of this guarantees UJET wins. Mitel's installed base is enormous, its partnerships give it a credible cloud story, and enterprise buyers are famously slow to rip out systems that still work. A company that names itself after speed - UJET reads as "you jet" - still has to convince cautious buyers to move, and it is going up against decades of relationships and reference customers. The reasonable read is not that one company is doomed. It is that the market is converging, and the newcomer with none of the legacy baggage tends to define the frame everyone else ends up defending.

05What you can actually do with it

For a business evaluating this space, the practical takeaways are concrete. UJET is aimed at companies that treat support as a product surface rather than a cost center - brands where a customer opening an app is the normal starting point, not a phone call. Its platform runs voice, chat, and digital channels through one system, layers AI on top of them, and with the Spiral acquisition adds analytics that read the whole conversation history for patterns. AXO is the piece designed to make the agent's day less miserable, which, unglamorous as it sounds, is often where customer satisfaction is actually won or lost.

There is also a lesson here that has nothing to do with contact centers specifically. Every technology eventually gets rebuilt by someone who never had to carry its baggage. The people who wired the first switchboards could not un-know how switchboards worked, and that knowledge became a kind of gravity. UJET's advantage is not that its engineers are smarter than Mitel's - it is that they started from a blank page in 2015 and got to ask, without flinching, whether the switchboard needed to exist at all. Incumbents rarely get to ask that question about their own product, which is why the answer usually comes from outside.

Mitel remains the safer, more familiar choice for organizations with heavy on-premises investments, complex telephony needs, and a preference for hybrid deployments they can control. The two are not identical products competing on a spec sheet. They are two answers to the same market, shaped by fifty years of distance between them - which is exactly what makes the comparison worth watching. Whoever ends up on top, the shape of the winning product is already becoming clear, and UJET has spent a decade sketching it.
