At 11 in the morning, a vacation rental stops being a holiday and becomes a stopwatch. One guest has left. Another may arrive at four. In between sit sheets, towels, dust, keys, damaged lamps, missing shampoo, a cleaner’s route across town and a host’s rising pulse. The interval is short, the work is physical, and the customer who notices it most is the one who never sees it happen. Tim Roy built his company in that invisible five-hour economy.
Roy is the COO and co-founder of Turno, the Honolulu company once called TurnoverBnB. The platform ties booking calendars to the people who reset short-term rentals. It can schedule a cleaner when a reservation ends, handle messages and payment, document work with checklists and photographs, and help a host find an independent cleaner when the trusted regular is unavailable. It is software for a handoff, which sounds modest until the handoff fails.
His route into that business was usefully indirect. Roy studied civil engineering at Notre Dame, then completed a master’s in the same field at the University of Hawai‘i at Mānoa. He worked on geotechnical projects, first at Pacific Geotechnical Engineers and later at Geolabs. The work involved field conditions, measurements, recommendations and the awkward fact that a structure is only as dependable as what supports it. Vacation rentals would offer the same lesson in a different material.
Third place, first developer
The partnership began at Shidler College of Business. Roy returned to the University of Hawai‘i for an MBA and met Assaf Karmon, a software engineer who had been hosting on Airbnb. Karmon’s irritation was painfully specific: coordinating cleaners through changing reservations consumed time and invited mistakes. He had already begun turning that nuisance into software. Roy brought operating discipline and a business-school alliance.
In their final semester, the pair entered the idea in a business-plan competition. They finished third. Founder mythology tends to reserve its lighting for winners, but third place did the practical job. The prize money paid for their first developer. That is a better startup fable anyway: the podium mattered less than what the founders bought after stepping off it.
“We accurately projected our revenue for several years in the future. I had no confidence they’d come true. But they did. It’s surprising.”Tim Roy
That confession is funny because it refuses the hindsight founders are often tempted to manufacture. Roy and Karmon may have drawn the correct line on a spreadsheet, but accuracy did not make the line feel inevitable. In the early days, the company’s revenue was measured in lunch money. The pair kept their attention on the next useful thing: scheduling first, then a marketplace, then payments and quality-control tools.
A surviving exchange from June 2017 catches Roy at ground level. He posted in an Airbnb hosts forum that he and a friend had written free software to schedule cleaners. Would anyone try it? The first volunteer complained that the confirmation email had not arrived. Roy, out to dinner, asked whether it had landed in spam. It had. Soon the conversation moved to ad hoc cleaning jobs and how cleaners preferred to receive alerts. Product discovery had begun before dessert.
For a while, the experiment ran beside Roy’s engineering career. He remained at Geolabs until 2019, roughly three years after the company began. The overlap complicates the usual leap-and-build story. Turno was not born from a theatrical exit. It was tested while one founder still had another profession, and while users were still explaining what the calendar needed to do. The pace was less cannonball than causeway: another section laid down whenever the previous one held.
The five-hour handoff
An engineer of invisible work
Calling Roy a former engineer misses the continuity. Civil engineering trains the eye downward, toward load, sequence and failure. As COO, he moved from physical ground to operational ground. Turno’s subject is not merely cleaning. It is dependency: a booking changes a date; the date changes a job; the job requires a person; completion releases a payment; the condition of the property shapes a guest review. One missed signal can travel through the entire chain.
The marketplace added another kind of structure. Hosts needed reliable local professionals, while cleaners needed steady work and a way to show credibility. Turno let cleaners set pricing and bid for projects, while hosts could compare offers, reviews and experience. Around that exchange grew the less glamorous machinery that makes a marketplace trustworthy: checklists, in-app chat, problem reporting, photographs and automatic payment.
By 2021, more than 20,000 short-term-rental hosts were using the business, and revenue had tripled since early that year. A $4.5 million Series A led by RET Ventures, with Blue Startups participating, supplied capital for hiring and international expansion. The following year, Hawaii’s venture community named Roy and Karmon Tech Entrepreneurs of the Year and recognized the funding as its Deal of the Year. Turno remained headquartered in Hawaii even as its customers spread across more than 70 countries.
From a local pitch to a global operating layer
Two founders, twelve time zones
Scale created a problem Turno could not solve with a cleaning checklist: how to make a far-flung company feel like one company. At one stage, its team stretched across a dozen time zones and seven countries. The founders experimented with virtual-reality meetings, online games and small rituals around birthdays and life events. In April 2022, colleagues gathered in Brazil, many meeting face to face for the first time.
“It was great to see everyone in person, eat together, drink together, talk, and create friendships. It was an amazing time.”Tim Roy on Turno’s 2022 summit
The remark is not a management framework, which is its charm. Roy described the ordinary acts that remote work tends to flatten. Eating together is not a KPI. Friendship does not fit neatly into a dashboard. Yet a company coordinating service work across continents depends on people trusting messages from colleagues they may never have met. The operator’s task includes repairing distance.
Roy’s life outside the company also revolves around coordination with conditions. He raced sailboats at Notre Dame. In Hawaii, he served on the boards of Kokokahi Sailing Club and Kaneohe Yacht Club, with additional finance and planning work at the latter. He has been described as spending free time racing, surfing and meeting friends for pau hana at the sandbar. Sailing and operations share a useful indignity: neither allows a person to negotiate with the wind.
A shorter name for a wider map
TurnoverBnB did what early company names often do: it explained the product at the cost of elegance. By February 2023, the business had mobile apps for hosts and cleaners, support in six languages, payment in multiple currencies and connections to major booking platforms and property-management systems. It served the United States, Canada, Europe, Australia and beyond. The old name had become both too long and too narrow.
The company shortened it to Turno. Roy announced the change as a promise to make things easy, simple and quick, then added the line that makes the corporate copy human: “Plus, 5-letter domains are cool.” Beneath the joke sat a coherent piece of strategy. A service built to remove friction had removed some from its own introduction.
The company’s direction has continued to widen without abandoning the original handoff. In June 2026, Turno hired Darrell Pratt as chief technology officer. Roy framed the appointment around experience scaling marketplaces and building AI products. The new CTO described an ambition to expand from cleaning into end-to-end property operations, including maintenance and recurring services such as moving trash cans to the curb.
There is poetry, of a stubbornly practical kind, in a software company aspiring to remember the bins. Travel technology usually sells the view: the blue water, the handsome kitchen, the promise of escape. Roy’s work sits behind the photograph. Someone must notice that the soap is low, that the previous guest left a mark on the table, that Wednesday’s checkout has become Thursday’s, that a cleaner deserves prompt payment.
The foundation beneath the listing
Turno’s story is easy to summarize as a sequence of milestones: two MBA classmates, a third-place pitch, a first developer, a marketplace, 20,000 hosts, a Series A, more than 70 countries, a new name. The more interesting sequence happens every day in miniature. A reservation ends. A person receives an assignment. Work becomes visible through a checklist and photographs. Money moves. A door opens at four.
Roy arrived at software after years spent thinking about foundations. He found another one hiding underneath hospitality. Guests rarely praise the coordination that made a room ready; they simply expect the room to be ready. That expectation supports an industry, and expectations are heavy things. The civil engineer in the COO seat appears to have recognized the load.
